Abstract
Laboratory and field experiments were conducted to evaluate the bio-efficacy of flubendiamide for the safety to lac insect and efficacy against associated insect-predators on lac culture. Eight concentrations of flubendiamide ranging from 0.0039 % (0.1 ml L−1) to 0.0315 % (0.8 ml L−1) were evaluated. No significant difference was observed on survival of emerging 1st instar lac insect larvae between various treatments and control as the result of dipping treatment of broodlac for 5, 10 and 15 min, indicating safety of the evaluated insecticide. Treatment of broodlac in insecticidal solutions for the same durations showed significant reduction in the population of both key lepidopteran predators, Eublemma amabilis (Noctuidae) and Pseudohypatopa pulverea (Blastobasidae) predating on lac insects. This is the first evaluation report of flubendiamide on lac insect ecosystem.
