A total of ten insecticides (single or mixtures) that is Dinotefuran + Spirotetramat (T1), Dinotefuran + Spirotetramat (T2), Pyriproxyfen+ Spirotetramat (T3), Pyriproxyfen+ Spirotetramat (T4), Spirotetramat (T5), Spirotetramat (T6), Pyrifluquinazon (T7), Pyrifluquinazon (T8), Flonicamid (T9), Flonicamid + Abamectin (T10) were applied two times in a field experiment on two varieties of understand (MNH-90 and BS-18) using randomized complete block design. Water (T0) dressed as control. Pyrifluquinazon @ 48.7 g/acre (T8) produced the maximum mortality (83%) of women of whitefly while the maximum nymphal mortality (78.4 %) was noticed in T8 (Pyrifluquinazon @ 48.7 g/acre). The maximum increase in boll pressure (133%) was observed in T8 (Pyrifluquinazon @ 48.7 g/acre) understood by T10 (Flonicamid+Abamectin) which present 110% increase over control. Pyrifluquinazon at 40 g/acre was establish to be more reliable than other proven insecticides, with a minimum decline of 31% in natural attacker population.
