Le résumé fourni par la source

The study was carried out for the assessment of abundance of predatory insects associated with lac insect Kerria lacca (Kerr) and their management through new insecticide molecule in kusmi lac during July-October 2015-16 and 2016-17. A combination of Emamectin benzoatate 5 % SG +Carbendazim 50 WP (T1), Indoxacarb 14.5 % SC + Carbendazim 50 WP (T2) and Control (T3) was evaluated against the predators of the lac insect. Pesticides application significantly reduced the incidence of major predators Eublemma amabilis Moore and Pseudohypatopa pulverea Mayr in comparison to (T3). There was a reduction in the population of predatory insects 81.97 per cent in T1 and 77.78 per cent T2 respectively over the year. It was seen that the different samples of lac collected from different lac growing areas of Chhattisgarh and noted that not a single sample was free from the attack of predator Eublemma amabilis Moore and Pseudohypatopa pulverea Mayr and appeared as major problem of lac host plants and losses consideration level in most of the areas.
