Influence Of Temperature On Development Of Coccinella septempunctata (Coleoptera, Coccinellidae)

open access: yes, 2016
It was established as a result of research that the development of ladybird proceeds faster at the temperatures from15°C to 30°C. Increasing the temperature above 30°C, has a negative effect on the development of this species. At 15°C, embryonic development is completed in 16-18 days, at 20°C - 19-20, at 25°C-6-8, 27°C - 4-5, 30°C - 4-5 days.

Laboratory Evaluation Of Coccinella Septempunctata Predation On Aphids And Mealybugs

open access: yesInternational Journal of Environmental Sciences
A study was done at SRM College of Agricultural Sciences (SRMCAS), Baburayanpettai, to find out if the ladybird beetle Coccinella septumpunctata could eat aphids and mealy bugs in Bhendi crops.In a free-choice test, results revealed that aphids were slightly more preferred (94.5%) than mealy bugs (84.82%), when both were exposed together to adults of ...
