Heterodera schachtii (Schmidt, 1871) (Nematoda: Heteroderidae) is one of the most widespread plant-parasitic nematodes (PPNs) associated with cabbages, which cause severe yield losses in cruciferous vegetables. This study aimed to improve the current understanding of the prevalence and detection of H. schachtii in the cabbage-growing areas of Niğde Province, Türkiye. Field surveys were conducted between November and December 2021, and 100 soil samples were collected immediately after cabbage harvesting. Heterodera schachtii populations were identified by morphological and morphometric methods along with Internal Transcribed Spacer of the ribosomal region (ITS-rDNA) and Cytochrome Oxidase Subunit (COI-mtDNA) sequencing. The mean body length of H. schachtii was 463 ± 7 μm, while stylet and hyaline length ranged between 20.7–27.8 μm and 20.1–32.1 μm, respectively. Nearly half of the surveyed areas were infested with H. schachtii with a 41% incidence rate. However, the Merkez District had the highest proportion of infested fields with an over 51% incidence rate. The population density was determined in 41 samples with a mean of 79.5 cysts per 250 g of soil. These results will help to determine the control and management strategies of H. schachtii.

Summary: Plant-parasitic nematodes are among the most influential soil organisms worldwide and have a detrimental impact on wheat productivity; they also play a major role in maintaining soil diversity. However, limited information is available on the biodiversity of nematodes associated with wheat cropping systems in Turkey. To address this knowledge gap, 45 wheat fields in the Afyonkarahisar Province of Turkey were sampled in 2021 in order to extract and identify nematodes. A total of 14 genera and 44 species of these nematodes were identified based on their physical traits and ITS DNA sequences examination. Shannon diversity index was used to determine the prevalence and biodiversity features of these nematodes. This study represents the first comprehensive research on plant-parasitic nematodes from wheat-growing regions in the Afyonkarahisar Province. The genera Helicotylenchus , Heterodera , Merlinius , Pratylenchoides and Pratylenchus dominated with a high relative abundance percentage >60%, and were extremely common (>90% for each). The average Shannon index of nematode species in the wheat fields was 2.20, with an evenness value of 0.81, indicating moderate diversification and good nematode evenness. This study also revealed a significant correlation between nematode genus biodiversity and edaphic, climatic and geographical factors. Finally, this research demonstrated a remarkable diversity of soil nematodes associated with wheat crops and they have the potential to be useful tools for extensive soil bio-study.

- Abstract
Root lesion nematodes (RLNs) (Pratylenchusspp.) are one of the most economically important plant parasitic nematodes (PPNs) and are considered one of the leading causative agents of apple diseases that severely decrease yield and quality in apple (Malus domesticaBorkh.) orchards. Occurrence, identification, and diversity of PPNs in apple orchards in central Anatolia region of Türkiye have not been well understood. Therefore, in this study, a field survey was conducted in this region to reveal the occurrence, distribution, and diversity of mainly RLNs. The primary analysis of soil and root samples based on morphology revealed that 8 PPN species were present in sampled areas, the most prevalent of which was RLNs. As a result of morphological, morphometric, and molecular studies, a total of 5 species of RLNs [Pratylenchus crenatusLoof, 1960; Pratylenchus neglectus(Rensch, 1924) Filipjev & Schuurmans-Stekhoven, 1941; Pratylenchus penetrans(Cobb, 1917) Filipjev & Schuurmans-Stekhoven, 1941; Pratylenchus thorneiSher & Allen, 1953 and Pratylenchus vulnusAllen & Jensen, 1951] were identified. Phylogenetic analysis with the D2–D3 domain of LSU-rDNA sequences further confirmed the identification. The results indicated that P. thorneiwas the predominant species in surveyed areas, followed by P. neglectus. The results confirmed the host status of apples for RLNs and demonstrated that RLNs were the most threatening PPNs in the surveyed apple orchards. The necessity of determining the damage caused by plant parasitic nematodes to apple production emerges as an important factor to be done as a future study.

Mediterranean cereal cyst nematode (CCN) Heterodera latipons is considered as one of the main CCN that causes significant economic losses in the production of intolerant cereal crops in Turkey. Accordingly, this study aimed at evaluating the effect of different storing temperatures and durations on the emergence of second-stage juveniles (J2s) of the nematode populations obtained from the eastern Mediterranean (Adana and Hatay) and south-eastern (Gaziantep and Kilis) regions of Turkey. The obtained results revealed a variation in the J2s hatching profiles of the regional nematode populations. The eastern-Mediterranean and the south-eastern populations hatched at between 5 and 20 °C; however, considerable divergences in the J2 hatching were noticed. The highest emergence of J2s for the populations occurred at 10 °C, whereas the lowest level was observed at 5 °C. To simulate the preplanting soil temperatures in Turkey, the cysts were stored at 5 °C and 20 °C, before incubation at 10 and 15 °C, to stimulate hatching of the J2s. The highest cumulative hatching was obtained at a constant temperature of 10 °C, while the lowest cumulative hatching occurred at 5 °C. Moreover, storing cysts at 5 °C, before incubation at 10 and 15 °C, significantly stimulated hatching of the populations of H. latipons when compared to the control. However, storing the cysts at 20 °C, before incubation at 10 °C, substantially stimulated the emergence of J2s relative to the control. The obtained results about the hatching behaviour of H. latipons may help in the development of effective control strategies for this nematode in Turkey. [ABSTRACT FROM AUTHOR]

Çevre Bilimleri - Abstract
Kök-ur nematodları geniş bir konukçu dizisine sahip olup önemli kültür bitkilerinde ağır verim kayıplarına neden olmaktadır. Türkiye’de nematodlar ile mücadelede nematisit kullanımına önemli kısıtlamalar getirilmekte bunun yanında mücadelede yeni metotlar ortaya konması gerekmektedir. Bu yüzden biber seralarında Kök-ur nematodları ile mücadelede alternatif mücadele programlarının geliştirilmesi büyük önem taşımaktadır. Bu çalışmada toprak solarizasyonu ile birlikte iki farklı kimyasal ve toprak fumigantının iki ve dört hat şeklinde damla sulama sistemi ile kombine edilerek nematodlarla ile mücadele programlarında kullanılabilirliği araştırılmıştır. Çalışmada solarizasyon + metam sodyum + iprodione uygulaması, dört lateral hatlı damla sulama sisteminde verime ve nematodun kökteki urlanması üzerine etkili bulunmuştur. Bitki boyu ve nematodun üreme gücüne solarizasyon + iprodione uygulamasının dört lateral hatlı damla sulama sisteminde en yüksek etkiye sahip olduğu saptanmıştır., Root-knot nematodes possess a wide group of hosts and cause significant yield losses in many economically important plant species. Restrictions on the use of nematicides in Turkey have increased; hence it is needed to discover new control methods for managing Root-knot nematodes.

The second stage juveniles (J2) of Root-knot nematode infect plant roots and feed on the inside roots as obligate parasites. After hatching, in case of inability to find plant roots, they die within a limited period. It is important to know the viability of second stage juveniles without feeding regarding their pathogenicity. In this study, the survivability of the second stage juveniles of root knot nematodes without feeding and the effect of different applications on hatching were investigated. In the first part of the study, the survival rate of Meloidogyne incognita and M. hapla second stage juveniles without feeding was determined. The survivability of M. incognita and M. hapla juveniles at differing time periods were determined by counting under the microscope. Juveniles were placed in a cold room in order to determine survival rate for 108 days at +4°C. The 50% of M. hapla lived until 71th day and 6,5% lived until 101st day in the cold room conditions. M. hapla juveniles entirely died on 108th day. The longest survivability of M. incognita juveniles was found on 66th day. In the second part of the study, the effect of tap water, hydrogen peroxide (H2O2) 3 different (1%, 2%, 3%) doses with 5 different temperatures (room temperature 16-22°C, 20°C, 25°C, 30°C, 35°C) applications were investigated on M. incognita egg mass hatching in laboratory conditions. The highest hatching rate was found from tap water at 30°C application and the least number of larvae hatching was determined on H2O2 applications., Kültür bitkilerinin obligat parazitleri olan Kök-ur nematodlarının yumurtalarından ikinci dönem larvaları (J2) çıktıktan sonra konukçu bitki kökü bulamayanlar belirli bir süre sonunda ölmektedirler. Yumurtadan çıkan larvaların beslenme olmaksızın yaşam sürelerinin bilinmesi nematodun patojenitesi açısından önem arzetmektedir. Bu çalışmada, kök-ur nematodu ikinci dönem larvalarının beslenme olmaksızın canlılıklarını sürdürmesi ve yumurtadan çıkışlarına farklı uygulamaların etkileri araştırılmıştır. Çalışmanın ilk aşamasında Meloidogyne incognita ve M. hapla türlerine ait larvaların beslenme olmaksızın yaşam sürelerini ortaya çıkarılmıştır. M. incognita ve M. hapla ikinci dönem larvalarının canlılık oranı mikroskop altında sayım yapılarak belirlenmiştir. Yaşam süresinin belirlenmesi amacıyla elde edilen nematodlar 108 gün süresince +4°C bekletilmiştir. Bu çalışmada, M. hapla 50. güne kadar %71’e yakın oranda canlılığını korumuş olup %6,5’i 101. güne kadar canlılığını koruyabilmiştir. M. hapla larvaları 108’inci günde tamamen ölmüştür. M. incognita’nın en uzun hayatta kalma süresi 66. güne kadar tespit edilmiştir. Çalışmanın ikinci aşamasında, M. incognita’nın yumurtalarından larva çıkışına laboratuvar koşullarında, çeşme suyu ve Hidrojen peroksit (H2O2)’in 3 farklı (%1, %2, %3) dozunun 5 farklı sıcaklıktaki (oda sıcaklığı 16-22°C, 20°C, 25°C, 30°C, 35°C) etkileri araştırılmıştır. En yüksek yumurtadan larva çıkışı 30°C çeşme suyu uygulamasından ve en düşük larva sayısı ise H2O2 uygulamalarından saptanmıştır.

Turkey is ranked among top ten wheat producing countries in the world. Cereal cyst nematodes are considered one of the most damaging plant parasitic nematodes on wheat worldwide. Up to date, the most effective method of controlling this group of nematodes is the use of crop rotation and resistant varieties. The successful development of disease-resistant plants is contingent on knowledge of the pathotypes of the causal agent. In this study, three populations of Heterodera filipjevi (Madzhidov, 1981) Stelter were collected from different locations (Afsin, Elbistan and Yozgat) in Turkey in order to identify their pathotype using “The International Test Assortment of Cereal Cultivars”. The results showed that two populations gave a similar reaction to the resistant and susceptible varieties. These populations were determined as Ha 33 pathotype which is a new report for Turkey., Türkiye dünya buğday üretiminde ilk on ülke arasında yer almaktadır. Tahıl kist nematodları dünya genelinde buğday yetiştiriciliğinde en zararlı bitki paraziti nematod gruplardan biri olarak bilinmektedir. Bugüne kadar yapılan çalışmalara göre bu nematod gurubu ile en etkin mücadele yöntemi münavebe ve dayanıklı çeşit kullanımıdır. Nematodlara karşı dayanıklı çeşit geliştirmede en önemli unsur hedeflenen alanlardaki nematodların popülasyonlarına ait patotiplerin belirlenmesidir. Bu çalışmada Orta Anadolu Bölgesi’nde buğday alanlarında yaygın bulunan ve önemli zarara neden olan Heterodera filipjevi (Madzhidov, 1981) Stelter’ nin patotipini belirlemek amacıyla üç farklı lokasyondan (Afsin, Elbistan and Yozgat) alınan popülasyonlar “Uluslararası test materyalleri” kullanılarak denemeye alınmıştır. Bu araştırma sonucunda her üç populasyonun H. filipjevi’nin Ha3 gurubu Ha 33 patotipine ait olduğu belirlenmiştir.

The cereal cyst nematodes, Heterodera avenae group, are known as parasites of cereals worldwide. In Turkey, the cereal cyst nematodes, Heterodera filipjevi, H. avenae and H. latipons, are the three known species infested wheat fields and cause high yield losses. The using of resistance varieties is one of the most effective methods for controlling cereal cyst nematodes. Recently, resistance genes (Cre genes) which are obtained from wild wheat genotypes have been transferred into bread wheat varieties to control the cereal cyst nematodes species. In this study, the efficiency of some sources of resistance (CreR, Cre1, Cre2, Cre3, Cre7 and Cre8) in wheat against some Turkish H. avenae, H. filipjevi and H. latipons populations was investigated in-vitro conditions. According to results, the effect of resistance genes showed variation depending on different Cereal cyst nematode populations; H.avenae, H. filipjevi and H. latipons. Although Cre1 gene was only found as completely resistant to all (three) nematode species, Cre3 and Cre7 were found resistant to H. avenae and H. latipons. Cre R was also determined as resistant to H. filipjevi and H. latipons populations but Cre8 was only found resistant against to H. filipjevi population. No resistance was found in Cre 2 gene against to all nematode populations. Additionally, 2 resistance gene-free variety and lines were found resistant to H. avenae; 3 wheat lines to H. filipjevi and 11 wheat genotypes were found moderately resistant to H. latipons., Tahıl kist nematodları, Heterodera avenae group, buğdayın önemli zararlılar arasında yer almaktadır. Türkiye’de buğday alanlarının Tahıl kist nematodları, Heterodera filipjevi, H. avenae ve H. latipons’la bulaşık olduğu bilinmektedir. Dayanıklı çeşit ve hatların Tahıl kist nematodları karşı kullanılması en önemli mücadele yöntemlerinden biridir. Son zamanlarda, Tahıl kist nematodlarına karşı buğdayın yabani formlarından elde edilerek ekmeklik buğday çeşitlerine aktarılmış birçok dayanıklılık (Cre genleri) geni geliştirilmiştir. Bu çalışmada dayanıklılık genlerinin (Cre R, Cre1, Cre2, Cre3, Cre7, Cre8) H.avenae, H. filipjevi ve H. latipons‘un ülkemizdeki bazı popülasyonlara karşı etkinlikleri in-vitro koşullarda araştırılmıştır. Çalışmada sonucunda Tahıl kist nematodları, H.avenae, H. filipjevi ve H. latipons popülasyonlarına göre dayanıklılık genlerinin etkinliklerinin değişiği; bunla birlikte Cre1’in her üç nematod türüne karşı tam bir dayanıklılığa sahip olduğu, Cre3 ve Cre7’nin H. avenae ve H. latipons’a, Cre R’nin H. filipjevi ve H. latipons’a, Cre8’in ise sadece H. filipjevi popülasyonlarına karşı dayanıklı olduğu ve Cre2’nin ise her üç nematod türüne karşı dayanıklılığa sahip olmadığı saptanmıştır. Ayrıca, dayanıklılık geni içermeyen çeşit ve hatlardan H. avenae karşı 2 adet, H. filipjevi karşı 3 adet, H. latipons’a karşı 11 adet buğday genotipi orta dayanıklı bulunmuştur.

Wheat (Triticum spp.) is highly susceptible to the root lesion nematode, Pratylenchus thornei, which causes excessive amounts of crop losses each year. In this research, we investigated the cumulative effect of the biocontrol agent Purpureocillium lilacinum (syn: Paecilomyces lilacinus) against P. thornei. Three doses of P. lilacinum (10
6 , 107 and 108 conidia cultures mL-1 ) with one dose of 400 P. thornei individuals (adults and juveniles) mL-1 were applied in 100 cm3 soil under greenhouse conditions. The number of nematodes in the soil and root in addition to total nematode in soil+root were determined. Moreover, different plant parameters such as the plant height, plant fresh and dry weight, root fresh and dry weight were evaluated. Applications with the higher dose of bio-agents (100 cm3 P. thornei infested soil with 108 conidia culture of P. lilacinum mL-1 ) exhibited maximal enhancement in dry and fresh weight of shoot and reduced P. thornei population. As a consequence, P. lilacinum individually was highly effective in enhancing different plant parameters and suppressing P. thornei reproduction. Overall, present findings suggest that the exploitation of the biocontrol agent P. lilacinum could be helpful for effective management of the root lesion nematode P. thornei.

TEZ6395 Tez (Yüksek Lisans) -- Çukurova Üniversitesi, Adana, 2007. Kaynakça (s.38-43) var. viii, 60 s. : rnk. res. ; 29 cm. This study was carried out in four olive orchards in years of 2006 and 2007 in Adana. Population dynamics of Olive fruit fly, Bactrocera oleae Gmel. (Diptera: Tephritidae) was determined by yellow sticky and Mcphail lure traps. To determine the natural enemies of this pest, damaged fruits and pupa inside the soil were collected, and then they were put into cages and parasitoits which were emerged from cages were send to experts for identification. In addition to the above, damaged fruits were counted and damage rate was determined. Olive fruit fly population reach 3-4 peaks around the year, but olive fruit fly population could not reach high population in Adana. This study revealed that McPhail lure traps captured less than 5-6 times when compared with other type of traps. Furthermore, this study exposes that damaged fruit rate reach to 4.3 % as a maximum rate which is so low. Among the natural enemies of this pest, parasitoits that belong to superfamily of Cynipoidea and families of Eulophidae, Pteromalidae were determined. Bu çalışma 2006-2007 yıllarında Adana ilinde 4 farklı zeytin bahçesinde yürütülmüştür. Zeytin sineği, Bactrocera oleae Gmel. (Diptera: Tephritidae)'nin ergin populasyon takibi, feromonlu sarı yapışkan ve McPhail besi tuzakları kullanılarak yapılmıştır. Zararlının doğal düşmanlarını saptamak amacıyla vuruklu zeytin taneleri ve toprakta pupalar toplanarak kültüre alınmış, kültür kafeslerinden çıkan parazitoitler teşhise gönderilmiştir. Ayrıca zeytin danelerindeki vuruk oranı da sayılarak zarar oranı saptanmıştır. Zeytin sineğinin yıl boyunca 3-4 tepe noktası yaptığı ve Adana ilinde yüksek popülasyon yoğunluklarına ulaşamadığı ortaya çıkmıştır. McPhail besi tuzaklarında yakalanan sinek sayısının diğer tuzak tipine göre 6-7 kat daha az olduğu ortaya çıkmıştır. Vuruk oranı en yüksek % 4.3'e çıktığı ve zarar oranın ise düşük olduğu belirlenmiştir. Zararlının doğal düşmanlarından Cynipoidea üst familyasına ve Eulophidae, Pteromalidae familyalarına ait parazitoitler saptanmıştır.

To determine the natural enemies of this pest. damaged fruits and pupa inside the soil were collected, and then they were put into cages and parasitoits which were emerged from cages were send to experts for identification. in addition to the above, damaged fruits were counted and damage rate was determined.Olive fruit fly population reach 3-4 peaks around the year, but olive fruit fly population could not reach high population in Adana. This study revealed that McPhail lure traps captured less than 5-6 times when compared with other type of traps. Furthermore, this study exposes that damaged fruit rate reach to 4.3 % as a maximum rate which is so low. Among the natural enemies of this pest, parasitoits that belong to superfamily of Cynipoidea and families of Eulophidae, Pteromalidae were determined.Key Words: Olive Fruit Fly, Bactrocera oleae,, Parasitoits 70

- Abstract
Background: Entomopathogenic nematodes (EPNs) (Steinernematidae and Heterorhabditidae) and their symbiotic bacteria are pathogenic for a wide range of insect pests and have been used successfully as a biological control agent. Although EPNs are well studied against many agricultural insect pests, the efficacy of their symbiotic bacteria still remains unclear for many insect pests of agricultural importance. In the present study, the virulence of native EPN isolates and their cell-free supernatants of symbiotic bacteria were tested against the 3rd and 4th larval instars of Agrotis segetum(Denis & Schiffermüller) (Lepidoptera: Noctuidae) under laboratory conditions (25 ± 1 °C and R.H. 60%). Results: The 4th instar larvae were more susceptible to infective juveniles (IJs) and mortalities over (95%) were achieved by all tested EPN isolates at the concentration of 100 IJs/cm
2 after 72 hrs of exposure. The cell-free supernatants were more effective against the 3rd instar larvae and the highest mortalities were recorded as 42 and 60% in the contact and leaf disc bioassays, respectively. Conclusion: The results indicated that the cell-free supernatants can be an ideal application for young larval stages of A. segetum. However, further studies are required to test the effectiveness of both EPNs and the cell-free supernatants of their symbiotic bacteria in field conditions.- Published
