Abstract
Investigations on “Life table, feeding potential and relative toxicity of
insecticides to ladybird beetle, Cheilomenes sexmaculata (Fabricius) were carried
out at Department of Agricultural Entomology, B. A. College of Agriculture,
Anand Agricultural University, Anand (Gujarat) during the year 2019-20. The
feeding potential of the predator was calculated on four hosts i.e., mustard aphid,
Lipaphis erysimi (Kaltenbach), cotton aphid, Aphis gossypii (Glover), maize aphid,
Rhopalosiphum maidis (Fitch) and cowpea aphid, Aphis craccivora (Koch). A total
of nine insecticides, viz.; acetamiprid (0.006%), buprofezin (0.05%), fipronil
(0.01%), flonicamid (0.015%), imidacloprid (0.089%), spinosad (0.0135%),
spiromesifen (0.0229%), thiacloprid (0.013%) and thiamethoxam (0.01%) were
evaluated.
