Colony composition, prey preference and behavioral characteristics of Leptanilla kubotai (Hymenoptera: Formicidae: Leptanillinae)
Get PDFLeptanilline ants are cryptic, and our comprehension of their natural history remains incomplete. We collected one colony of Leptanilla kubotai in October 2023 and investigated the colony composition and behavioral characteristics of this rare species. The nest of Leptanilla kubotai was
situated 15 cm deep in the soil and contained one dichthadiiform queen, 453 workers, and 663 larvae. The queen had 88 ovarioles, while the workers had no ovaries. Workers were specialized predators of geophilomorph centipedes, and promptly recruited nestmates upon encounter with a prey. Larvae showed remarkable mobility, associated with unique morphological features: a ventral hooked claw on their prothorax and a row of teeth on the external margin of their mandibles. The queen and workers performed larval hemolymph feeding and likely rely on larvae for nutrition in the absence of prey. We compare these findings to other Leptanillinae and discuss the specialization of Leptanilla for a subterranean lifestyle.journal articl
Report on the Kagawa University JICA 2024 Nikkei Training Project
Get PDFThis report highlights the Kagawa University JICA 2024 Nikkei Training Project, a collaborative initiative by the Faculty of Agriculture and the International Office at Kagawa University. The project successfully concluded through joint efforts and was held at multiple locations, including the Japan International Cooperation Agency （JICA） Yokohama Center, the Faculty of Agriculture at Kagawa University, the International Office at Kagawa University, and various on-site venues. This intensive training program spanned four weeks, running from October 15 to October 30, 2024, and provided participants with a highly engaging learning experience. The program was funded by the Japan International Cooperation Agency （JICA）, which also facilitated pre-training at the JICA Yokohama Center. It was coordinated and implemented by the Faculty of Agriculture and the International Office. Eight entrepreneurs of Japanese ancestry, from Paraguay, Brazil, Mexico, Colombia, and Bolivia, were invited to join the program. These individuals were motivated by the desire to establish and grow new food-related businesses in their respective countries. This report offers a detailed summary of the project, covering its planning process, goals, and outcomes. It also includes evaluations and feedback from participants, organizers, and JICA representatives．departmental bulletin pape
