Phytophagous insects differ in their degree of specialization to their host plants. It ranges from monophagous or oligophagous species that can only develop on a single host plant, or family of host plants, to extremely polyphagous species that can develop on plants from many distinct botanical families. The aim of this study was to compare the larval performance and adult preference of a highly generalist species, the Queensland fruit fly (Bactrocera tryoni) and a highly specialist species, the breadfruit fruit fly (B. umbrosa) among several fruits covering both species' host range. (i) larval performance was tested on 16 fruit species, and (ii) a female preference was tested on a subset of five fruit species. In addition, (iii) a field survey was carried out on 11 fruit species. B. umbrosa infested only Artocarpus fruits in the field. Accordingly, B. umbrosa larvae survived and developed only on fruits belonging to the Artocarpus genus. Female B. umbrosa did not lay their eggs on non‐Artocarpus fruits, except Terminalia catappa. Female B. tryoni, on the other hand, made little selection between the fruits tested, and its larvae developed on 13 of the 16 fruit species tested. The larval performance of both species, adjusted when tested by female preference, predicted in large part the fruit infestation in the field. These data are essential to better estimate invasion risk where the species are not established. [ABSTRACT FROM AUTHOR]

In the formation of helminth fauna, the formation of a high diversity of species, in the circulation of helminths between humans and ruminant domestic animals in nature and in their infection, in the completion of the development stages of biohelminths and their invasion and in the transfer of dangerous helminths from one area to another, their intermediate hosts have a great role. When determining the role of intermediate hosts in the spread of helminths of domestic carnivores, it was found that the intermediate hosts of 12 species of helminths are insects, 7 species are ruminants, 16 species are rodents, 5 species are reptiles and 3 species are earthworms. During the study, it was found that rodents were infected with cysticercoids of the mentioned helminths in 49.3%, reptiles with cysticercoids, procercoids and plerocercoids in 34.7%, snails in 24.7% and insects in 37.3%. Among the intermediate hosts, rodents prevail over other intermediate hosts with 16 species and infection rate of 49.3%. It comes from the ethology of rodents. The scientific-research work carried out in this direction has important theoretical and practical importance. The main direction in the fight against intermediate hosts is to break the chain between transmissible diseases and the agent that transmits them. [ABSTRACT FROM AUTHOR]

This research aimed to develop science teaching materials based on marine aquaculture bioecology using floating net cage technology that is practical and effective in improving students' scientific literacy skills at Lombok coastal schools. This was development research based on the Thiagarajan 4D model, which consists of four stages: design, define, develop, and disseminate. The research subjects consisted of six junior high schools on the coast of Lombok, who were selected using the purposive sampling technique. The instrument used was a scientific literacy assessment of 16 reasoned multiple choice questions. Data were analyzed using normalized gain analysis. The results showed that science teaching materials based on marine aquaculture bioecology with floating net cage technology were effective in increasing the scientific literacy skills of students in the six sampled schools, obtaining an average N-gain value of 0.5 in the medium category.

Against the background of climate change and scarce non-renewable resources, transforming the fossil-based toward a bio-based economy is considered crucial for sustainable development. Numerous countries have released governmental strategies outlining their bioeconomy visions. This study examines the bioeconomy visions presented in 78 policy documents from 50 countries worldwide, building on earlier vision typologies. Through qualitative content analysis, 227 distinct policy goals were identified and analyzed. Descriptive statistics were used to determine the salience of specific goals, overarching goal categories, and distinct bioeconomy visions: bioresource, biotechnology, and bioecology visions. The results reveal that goals and visions prioritize economic growth, while environmental considerations are less salient. The bioresource vision emerges as the globally dominant perspective, while the bioecology and biotechnology visions have lower salience. These findings deepen our comprehension of current bioeconomy policies and emphasize the need for critical research on bioeconomy visions and their implications for public policy.

DNA barcoding and morphological characters together with thorough bioecological investigations to diagnose field bean pod borer, Adisura atkinsoni Moore, 1881 an important pest was carried out. A. atkinsoni has a limited host range. The incidence of Adisura was higher on local varieties (photo sensitive) compared to HA4 hybrid (photo-insensitive). The field bean pod borer appeared during middle of October and continue to March. The undefined taxa were identified using both female and male genitalia. But since they could be differentiated from their morphologically closest relative, they were marked as sensu lato. While doing BLAST analysis, the mitochondrial COI Sequence of Adisura specimens collected from Bengaluru showed similarity to A. bella. In the phylogenetic tree, these two samples Sp1 and Sp2 separate new sub-clade which stands separately from the rest of the Adisura species. It was identified that the lepidopteran samples collected from Bengaluru are Adisura and the DNA sequences did not match with any of the existing species of Adisura. The shift in this pest's prevalence has been discussed. [ABSTRACT FROM AUTHOR]

Tuberose (Agave amica (Medikus) Thiede and Govaerts) is a hardy and economically important flower crop in India. Tuberose growers have been facing severe loss in flower yield due to the large-scale deformities and rotting of buds caused by midge fly attacks. Morphology and DNA barcoding have confirmed the identity of this midge species as Contarinia maculipennis Felt (Diptera: Cecidomyiidae). Maggot feeding causes deformation and rotting of the infested buds and imparts an ugly appearance to the tuberose florets. Midge fly infestation ranged from 5.67% to 88% from July to September 2022 in different tuberose-growing areas of Maharashtra, Telangana and Andhra Pradesh in India. The bioecology of this midge species and the nature of damage to tuberose were studied to develop eco-friendly management methods. This study offers novel insights into the nature and extent of midge damage to tuberose and how midge symptoms differ from tuberose melody symptoms caused by the foliar nematode.

The alien brown seaweed Sargassum muticum (Yendo) Fensholt is currently observed along the coasts of Morocco. The present study aimed to evaluate the impact of physicochemical parameters on the distribution of S. muticum at four sites on the Atlantic coast of Morocco harvested between 2019 and 2020. This study showed that the highest biomass, thalli length, and fertility values were recorded in sampling sites characterized by optimal physicochemical (temperature, pH, and salinity) and nutrient H₃PO₄ during summer. The highest biomass values were recorded in August for Sidi Bouzid and Moulay Abdellah sites, conversely, in Saada and Jorf Lasfar sites the highest values were observed in February and March respectively. The thallus length was slightly larger in Moulay Abdellah site with 77.30 ± 14.09 cm compared with the three other sites during the summer/spring periods. Minimum thalli length was recorded in September for all studied sites. The thalli of S. muticum were fertile earlier in Sidi Bouzid and Saada during spring and peaked during the summer season for all studied sites showing a positive correlation with increasing temperature. Finally, the collected data shows that indeed physicochemical parameters influence bioecological parameters. Thus, contributed to a better understanding of the temporal variation of S. muticum phenology on the Moroccan Atlantic coast, these data provide the necessary information for coastal marine management and biomonitoring program as well as sustainable utilization of this renewable marine resource. • The study examines Sargassum muticum in Morocco's Atlantic coast, focusing on its spread and impact. • It looks at how environmental factors affect S. muticum across four Moroccan coast sites from 2019 to 2020. • Ideal conditions like temperature, pH, salinity, and nutrients boost S. muticum growth in summer. • Biomass peaks in August at Sidi Bouzid and Moulay Abdellah, but in February and March at Saada and Jorf Lasfar, showing growth differences. • Moulay Abdellah has longer thalli in summer/spring, with a slight decrease in September everywhere. • Fertility starts earlier at Sidi Bouzid and Saada in spring, peaking in summer across all sites due to rising temperatures. • The study emphasizes how environmental factors affect S. muticum , urging better coastal management. • It enhances understanding of S. muticum 's cycle along Morocco's Atlantic coast, aiding marine management and resource use.
