Abstract

Nimbecidine (Contains 0.03% azadirachtin) and Green Miracle (antitranspirant) were tested alone and in combination against Aphis craccivora Koch. Nimbecidine was found to be highly effective in compared with Green Miracle at all concentrations tested against this aphid species. Ninety and fifty percent lethal concentrations (LC90,50) were 0.4 and 0.13 ml/l for nimbecidine, 3.5 and 1.7 ml/l for Green Miracle,  respectively.  LC90 and LC50 were2.2 and 1.3ml/l when mixing Nimbecidine and green miracle together. The Ninety and fifty percent lethal times (LT90,50) were 6.2 and 4.2 days at 0.6ml/l for Nimbecidine, 4.8 and 2.9 days at 5.0ml/l for Green Miracle. Mixing Nimbecidine and Green Miracle achieved LT90,50 values as 3.1 and 2.2 days(at 0.3 N + 3.0 G ml/l). The highest concentration for each formulation tested caused percentage reduction in the number of young born as 92.25% at 0.6 ml/l for Nimbecidine,  91.46 % for Green Miracle and 95.4%  at 0.3 N+ 3.0G ml/l for combination. The natal period and longevity decreased as concentration increased. The different concentrations for Nimbecidine, Green Miracle and in combination caused retardation in the development of the fourth nymphal instar. Nimbecidine and Green Miracle could be used in combination in integrated pest control.
