New country and host records of Trichogramma species for Turkey are presented. Trichogramma aurosum Sugonjaev & Sorokina is recorded for the first time from Turkey, and a new species, T. zerynthiae Polaszek & Bolu, is described. Morphological identification based on dissected male genitalia is supplemented by molecular sequence data. [ABSTRACT FROM AUTHOR]

Kusuhara. • • Gonatocerus cincticipitis is an egg parasitoid of green rice leafhopper, Nephotettix cincticeps. • •The previously reported genetic identity of Gonatocerus cincticipitis was incorrect. • • Gonatocerus cincticipitis is a member of a morphologically difficult species complex. • •Revised molecular identity of Gonatocerus cincticipitis facilitates its positive identification. Gonatocerus cincticipitis Sahad (Hymenoptera: Mymaridae) is an egg parasitoid of the rice pest, green rice leafhopper Nephotettix cincticeps (Uhler) (Hemiptera: Cicadellidae), in Japan and the Republic of Korea. Its molecular determination is reconsidered following the previous taxonomic misidentification, and its genetic separation from G. saipanensis (Doutt), a morphologically identical Gonatocerus sp. from Shimane Prefecture, Honshu Island in Japan, and other members of the Gonatocerus fuscicornis (Walker) species complex is demonstrated and discussed. DNA was successfully extracted from reared specimens of G. cincticipitis from Honshu and Kyushu islands in Japan, and the standard barcoding section of the mitochondrial cytochrome oxidase subunit 1 gene (COI) as well as two regions of nuclear ribosomal RNA, the D2 domain of 28S (28S-D2) and the internal transcribed spacer 2 (ITS2), were amplified and sequenced for genetic analyses. Both sexes of G. cincticipitis are redescribed and illustrated to facilitate their recognition. An updated morphological key to females of the Palaearctic species of Gonatocerus Nees ab Esenbeck is also provided. [ABSTRACT FROM AUTHOR]

The Euwallacea fornicatus species complex is native to Asia but has invaded many countries globally. This complex includes four cryptic species that infest a wide range of economic crops, including tea. One of them is Euwallacea perbrevis Schedl, which has been a major pest of tea in Sri Lanka and India for over a century. The species complex was first recorded infesting tea in Taiwan over 80 years ago but the specific identity of that first record is unknown. Furthermore, although tea is an important industry in Taiwan, this pest has attracted limited attention. Hence, we surveyed tea gardens across the island, determining infestation rates, and identifying the Euwallacea species present. We also used sticky traps to monitor the annual flight dynamics of the beetles and of a parasitoid natural enemy, an undescribed species of Eucosmophorus. Levels of infestation varied even between neighboring gardens. Highly infested tea gardens were located mainly in central Taiwan and some in eastern Taiwan. The peak flight activity of the species complex occurred between October and March, when the parasitoid was also abundant. Molecular identification of the trapped beetles identified them as E. fornicatus sensu stricto Eichhoff and E. kuroshio Gomez & Hulcr, but E. perbrevis was not detected. In contrast to the situation in Sri Lanka, where E. perbrevis attacks the highly visible terminal branches of the tea plant, in Taiwan, E. fornicatus s. s. and E. kuroshio predominantly attacked the main bole and underground parts. We propose that the 'hidden' nature of this attack, and the similarities of the symptoms to a common fungal disease of tea, may have led to an underestimation of the impact of the species complex on tea, not only in Taiwan but also in other tea growing countries. • E. fornicatus s. s. and E. kuroshio are dominant in tea gardens of Taiwan. • E. perbrevis was not detected in tea gardens of Taiwan. • Peak flight activity of SHB occurred between October and March. • SHB prefer to attack lower part of the main trunk of the tea plant.

[Display omitted] • Amrasca biguttula is an economically important pest of okra, Abelmoschus esculentus , in Japan. • Five species of Mymaridae and one of Trichogrammatidae were reared from okra leafhopper eggs. • Anagrus turpanicus was newly recorded from Japan. • Anagrus ? atomus , A. turpanicus and Pseudoligosita nephotetticum are for the first time reported from eggs of okra leafhopper. The okra leafhopper, Amrasca (Sundapteryx) biguttula (Ishida) (Hemiptera: Cicadellidae), is an economically important pest of okra, Abelmoschus esculentus (L.) Moench (Malvaceae), in Japan. During 2019 and 2022 surveys for its egg parasitoids (Hymenoptera) were conducted on Kyushu and Ryukyu islands in southern Japan. Five species of Mymaridae, Anagrus (Anagrus)? atomus (L.), A. (A.) japonicus Sahad, A. (A.) turpanicus Triapitsyn and Hu, Arescon enocki (Subba Rao and Kaur), and Stethynium empoascae Subba Rao, as well as one of Trichogrammatidae, Pseudoligosita nephotetticum (Mani), were recorded from eggs of A. biguttula on okra in Japan. Of these, A. (A.) turpanicus , identified using a combination of molecular and morphological methods, is newly recorded from Japan; A. (A.)? atomus , A. (A.) turpanicus and P. nephotetticum are for the first time reported from eggs of okra leafhopper. [ABSTRACT FROM AUTHOR]
