Abstract:

The mortality and sub-lethal effects were determined on development of surviving of S. litura on Insect growth regulator, Methoxyfenozide 240 SC (Dose: 1680, 1440, 1200, 960 and 720 ppm, were dissolved in water and each treatment was replicated 3 times. The results indicated that the copulation time, fecundity and fertility decreased when compared with control (distilled water). The maximum mortality observed on dose one after one week and minimum on dose five after 24 hours with the maximum larval weight reduction on dose one and dose three after 24 hours. The longest larval and pupal period, short adult longevity, maximum pupal weight reduction, longest duration of life-cycle, shortest copulation time, minimum fecundity and minimum fertility of eggs were recorded in dose one and highest in dose five. It is concluded that the methoxyfenozide (IGR) effective by their sub-lethal concentrations however, most preference can be given to which caused highly sub-lethal effects on the reproduction and biology of S. litura under laboratory conditions.
