Abstract

        Four formulation products include Profenofos (OP), Pyriproxyfen (IGR)- Spinosad (Biotic agent) and Light mineral oil (CAPL-2) oil 96.62% E.C. were sprayed by using economy micron ULVA Sprayer in Laboratory with four different concentrations and control treatment with water on castor oil plant leaves and water sensitive paper to determine the spray coverage of each treatment.
        Results indicated that Profenofos, Pyriproxyfen and Spinosad are the most effective in larval mortality and followed by CAPL-2. Also, Profenofos, Pyriproxyfen and Spinosad are more affected on pupation and pupal weights followed by CAPL-2. The adult emergence affected more at 30, 45 and 60 ppm of Profenofos, 400 ppm of Pyriproxyfen, 350 ppm of Spinosad followed by 200 ppm of CAPL-2 oil. The most efficient compounds are those of Pyriproxyfen and CAPL-2 oil that reduced a sever reduction in the fecundity and fertility followed by Spinosad and Profenofos,similarly longevity was strongly affected by Pyriproxyfen, but Spinosad, CAPL-2 and Profenofos has slightly effect under lab. Conditions Data showed also that, there was a negative correlation between N/cm² and the percentage corrected larval mortality in all treatments, except in the case of CAPL-2 oil, the correlation was positive. No significant differences between VMD of droplet sizes and the percentage corrected mortality. The ration [VMD],[N/cm²] was developed toward a tendency to homogeneity of spray spectrum with increasing the concentration used in all the treatments.
