Title

THE EFFECTS OF ABAMECTIN ON BEMISIA TABACI (HOMOPTERA: ALEYRODIDAE) AND ERETMOCERLLS MLLNDLLS (HYMENOPTERA: APHELINIDAE)

Pages

  173-192

Abstract

 The effect of six concentrations (0.25, 0.5, 1, 2, 4, and 6 mg/l) of ABAMECTIN was evaluated on 1 and 4-day eggs, different nymphal instars, and pupae of Bemisia tabaci Gennadius (Hom.: Aleyrodidae) and also eggs, larvae, pupae, and adults of Eretmocerus mundus Mercet (Hym.: Aphelinidae) as the efficient parasitoid of B. tabaci. Morphological and biological effects of the insecticide were also studied on first and second generations of the parasitoid. The susceptibility of one-day eggs of B. tabaci to the insecticide was more than tour-day eggs, and also early nymphal instars (1 st and 2nd) than 3rd and 4th instars, and pupa. Application of ABAMECTIN in larval stage of parasitoid, affected the head capsule width, fecundity, and longevity. The effect of insecticide on pupal stage of the parasitoid had significant effect on head capsule width, antelmal sensilla, developmental time, longevity, and fecundity, but no significant effect on the adult eclusion percentage. The effect of insecticide on I-day eggs of the parasitoid increased mean developmental time of immature stages. The insecticide residues had significant effect on longevity and sex ratio, but did not affect fecundity, survival percentage, and morphological characters of 2nd generation individuals. Results of the present research indicated that ABAMECTIN has the destructive and sever effects on E. mundus. Therefore, application of the insecticide, meantime of observance of suitable concentration (2 mg/l) and golden time application (early nymphal stages of B. tabaci, and contemporaneously pupa of E. mundus) is possible in integrated pest management programs of sweetpotato whitefly.
