EFFECT OF NEEM AZAL TIS ON THE TWO-SPOTTED SPIDER MITE Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE )

Abstract
The effects of Neem Azal- TIS, a commercial product, on various developmental stages of the two-spotted spider mite, Tetranychus urticae Koch were tested in the laboratory. Neem Azal TIS was tested for its effect as a deterrent, toxicant, developmental retarding and antiovipositional of the pest T. urticae. The product exhibited strong deterrent for T. urticae females, and the percentage of 001 was increased as the concentration increased to reach 94.17% at 0.4 % conc. The developmental period of both treated larval and proto nymphal stages were significantly prolonged. Female longevity resulted from treated larvae, protonymphs and newly-emerged females was shortened and a remarkable depression in fecundity was noted at all tested concentrations. A decrease in the percentage of egg hatchbility was recorded at 0.4 and 0.2 % concs., while an increase in female mortality was observed.
