Among 25 insecticides and biorationals evaluated with and without Fish Oil Rosin Soap (5 ml/l) against different instars of scale insect, Hemilecanium imbricans, the insecticides viz., buprofezin 25 SC @ 1.25 ml/l, chlorpyriphos 20 EC @ 2 ml/l, acephate 75 SP @ 1 g/l, lambda-cyhalothrin 5 EC @ 0.5 ml/l, profenophos 50 EC @ 2 ml/l and dichlorvos 76 EC @ 1 ml/l were recorded highest per cent mortality of scales under laboratory conditions. Irrespective of treatments imposed with and without FORS against different stages of scale insect, H. imbricans similar effects were produced with respect to mortality percentage with little variation. With respect to instar susceptibility, the first instars (crawlers) and second instars of H. imbricans were shown more susceptibility to all combination treatments compared to third and fourth instars under laboratory conditions.

Keywords: Scale insect, Hemilecanium, Insecticides, Biorationals, Mortality, Fish Oil Rosin Soap (FORS) etc.
