Studies were conducted on the occurence of metabolic mediated resistance in cotton aphid, Aphis gossypil to selected insecticides viz., endosulfan, monocrotophos, dimethoate, phosphamidon, carbaryl and cypermethrin using synergist TPP suppressible metabolic resistance even at 1:5 ratio in respect of monocrotophos and cypermethrin.
The samples of okra and brinjal fruit and soil collected from non-IPM and IPM fields were analyzed for insecticides viz chlorpyriphos, cypermethrin and monocrotophos, widely used in these crops in adopted village Raispur, in Ghaziabad District (UP).
Newly developed Enzyme Linked Immuno Sorbent Assay (ELISA) technique has been used for monitoring of wheat grain and flour samples for endosulfan residues. Data indicated that eight samples out of fifteen contained endosulfan residues. The average concentation varied from 0.65-6.1 ppm. ELISA data correlated well with GC analysis with correlation coefficient of 0.98.
