Plant growth stimulants 'Miraculan' gradually decreased survival of the larvae of Spodoptera litura from 86.67 to 46.67 per cent at 3.22 to 100 ppm. Similar trend was also observed in adult emergence. Growth indices were lower in all treated diets as compared to control. The results of the experiment showed that artificial diet fortified with different levels of Miraculan (plant growth stimulant) has adverse effect on the survival and development of Spodoptera litura. Reduction in per cent pupation, adult emergence and larval survival of S.litura indicates the role for these growth regulators in IPM.Keywords
Spodoptera litura (fab.), Miraculan

Deltamethrin was found to be most toxic against the larvae of Spilarctia obliqua followed by triazophos, spinosad, chlorpyrifos and fipronil in leaf dip. LC50 of deltamethrin at 12, 24 and 48 hours after treatment (HAT) was 0.008, 0.0001 and 0.00002 per cent respectively through larval dip method. With leaf dip method the LC50 was 0.007, 0.0002 and 0.00002 at 12, 24 and 48 HAT respectively. Being the novel mode of action and safety point of view spinosad was the most promising insecticide which gave the satisfactory control with safety measures, application and environment.Keywords

An attempt was made to assess the toxicity of some novel molecules of insecticides against Spodoptera litura (Fab.). The dose mortality response to the 7 d old larvae of S. litura indicated that spinosad at 24 h was 4.773 times more toxic than cartap hydrochloride at LC50 value. By the lapse of time this ratio further increases to 82.5 at 48 h and 71 times at 72h. The relative toxicity ratio (RTR) of novel molecules at LC50 value in comparison to cartap hydrochloride at 24h and 48h were: spinosad (4.77, 9.9)> fipronil (1.59, 3) and at 72h the values were spinosad (10.14) and fipronil (2.54). LC50 values of cartap hydrochloride, fipronil, spinosad, as 0.44% and 0.126%; 0.0418% and 0.079%; 0.004% and 0.0264% respectively at 24 h.Keywords
