Abstract

Species diversity plays an important role in shaping the behavioural responses and ecological performance of insects. The present study investigates the influence of species diversity on the behavioural traits of the tropical tasar silkworm (Antheraea mylitta). The study was conducted under natural rearing conditions in tasar-growing areas where different host plant species were available. Key behavioural parameters such as feeding behaviour, resting pattern, locomotion and host plant preference were observed and recorded during different larval instars. The results revealed significant variations in behavioural patterns in relation to species diversity and host plant availability. Larvae exhibited higher feeding frequency and activity levels in habitats with greater plant diversity. The findings suggest that species diversity positively influences the behavioural adaptability of tasar silkworms and may contribute to improved survival and growth. This study highlights the ecological significance of biodiversity in sustaining tasar sericulture and insect adaptation.
