Cannibalism Behaviour of a Ladybird Beetle, Cheilomenes sexmaculata Fabricius (Coleoptera:Coccinellidae) due to its Densities

India has an incredible affluent assortment of both flora and fauna. The fauna is extremely distinctive establishing the ecosystem steadiness in a drastic comportment. Ladybird beetles are cosmopolitan in distribution. They diminutive insects ranging in size from 1-10 mm, vibrantly clad with shades of red, yellow or orange with spots on their elytra, belonging to the order Coleoptera and family Coccinellidae.

They are elected as farmer's friends as they prey upon a number of insect pests like aphids, mealybugs, thrips other soft bodied insects and phytophagous mites. They are persuasive biocontrol agents and indispensable gears of integrated pest management. They have already been time-honored as successful biocontrol agents against coccids, diaspids and other pest infestations. Present work spotlights on the effect of density on cannibalism by different larval stages of the zigzag ladybird beetle, Cheilomenes sexmaculata.
