Efficacy of bio- and synthetic pesticides to Lipaphis erysimi Kalt. and its predator, Ischiodon scutellaris (Fabricius) in broccoli ecosystem

Field experiment conducted to evaluate the toxicity of bio and synthetic pesticides to Lipaphis erysimi Kalt. and its predator, Ischiodon scutellaris (Fabricius) in broccoli crop at the experimental farm, ICAR Research Complex for NEH Region, Mizoram Centre, Kolasib, Mizoram, India showed that application of synthetic pesticides recorded 100% reduction in the L. erysimi population. Synthetic pesticides were highly toxic to I. scutellaris and resulted in 100% mortality. Imidacloprid 17.8% SL was less toxic to I. scutellaris when compared to other synthetic pesticides. Neem oil formulations were effective against L. erysimi and did not have any detrimental effect on the maggots of I. scutellaris.
