Abstract
The present study was conducted to evaluate the effect of buprolord as IGR against the two spotted spider mites (TSSM), Tetranychus urticae Koch. Also, the behavioristic action of mixture of buprolord and extract of Ipomoea carnea was included. A positive correlation between concentrations used and mortality percentages was recorded. The idea was to try to reduce the extravagant of traditional pesticides. Buprolord was effective against T. urticae, protonymphs. When old eggs were treated with 250 ppm of the mixture kindly results were obtained. Mortality percentages were increased directly proportional with increasing concentration of buprolord. Old eggs of the mite, T. urticae were susceptible to the tested concentrations of buprolord during 72 hr. than in 24hr. where they were more sensitive. Concentration of 250 ppm on T. urticae old eggs gave 26.06/female. On the other hand, the lowest concentration of 25 ppm gave 65.61 eggs compared with 65.35 eggs for the untreated females. The IGR used here extended the developmental period to T. urticae by delaying the developmental rate. Conclusively, The present study was conducted to evaluate the effect of buprolord as IGR against the two spotted spider mites (TSSM),Tetranychus urticae Koch. Buprolord was effective against T. urticae, protonymphs. Old eggs of the mite, T. urticae were susceptible to the tested concentrations of buprolord during 72 hr. than in 24hr.. The IGR used here extended the developmental period to T. urticae by delaying the developmental rate.
