Bio-efficacy, persistence and residual toxicity of greener insecticides against predominant flea beetles on cabbage crop in Kashmir
The flea beetles, Phyllotreta striolata (Fabricius, 1803) and Altica himensis (Shukla, 1960) (Coleoptera: Chrysomelidae: Alticinae) are one of the most serious pests of Brassica oleracea L. in Kashmir.

| description |
The flea beetles, Phyllotreta striolata (Fabricius, 1803) and Altica himensis (Shukla, 1960) (Coleoptera: Chrysomelidae: Alticinae) are one of the most serious pests of Brassica oleracea L. in Kashmir. In order to find eco-friendly control against these pests, bio-efficacy, persistence and residual toxicity of some newer insecticides viz., Emamectin benzoate 5SG @ 0.002 and 0.004 per cent, Spinosad 45SC @ 0.0035 and 0.007 per cent was evaluated against P. striolata and A. himensis infesting cabbage crop. Mortality caused by these insecticides was recorded in all the treatments. The result revealed that spinosad 45SC @ 0.007 per cent exhibited significantly lowest pest population and the highest efficacy against cabbage flea beetles. The persistence and residual toxicity of these insecticides was worked and it was found that spinosad 45SC @ at 0.007 per cent revealed the highest PT value of (346.11 & 321.43) for P. striolata and (299.57 & 322.38) for A. himensis compared to other insecticides. LT50 values of (4.13 & 3.38) for P. striolata and (3.08 & 3.84) for A. himensis were the highest for Spinosad 45SC @ 0.007 per cent. It was concluded that spinosad 45SC @ 0.007 per cent offers a feasible choice for the management of P. striolata and A. himensis.
