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

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. The optimum temperature for the development and reproduction of beetles is considered to be 25-27°C. The hatching rate of larvae at a temperature of 25°C was 99.1 1.59, and the mortality rate was 0.9 1.21. Under this regime, the sex ratio was: 58.6% - females and 39.8% males, which has undoubted practical significance
