Abstract
The present study analyses the influence of container size available during foraging on the demographic attributes of ladybird beetle Menochilus sexmaculatus (Fabricius; Coleoptera: Coccinellidae). To provide variations in the foraging arena, we used a small petri dish, large petri dish, and beaker as small, medium and large containers for foraging. Results revealed significant influence of container size on life attributes. Developmental attributes of M. sexmaculatus were better in the small arena followed by medium and large arenas. The highest mortality rate and maximum life expectancy were recorded in a large arena, followed by medium and small arenas. Reproductive attributes (fecundity and oviposition period) were much better in the large arena. The results of this study indicate that a small container encompassing small foraging arena is beneficial for immature development and survival, while a large container encompassing large foraging arena is best for the reproductive attributes of adults.
