Abstract | ||||
The effect of two fungus insecticides .Beauveria bassiana (Bals.) Biosect and Biofar was evaluated at the rates of 200 gm; 100gm.l100L. water against the white fly. Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) at Etay·Elbaroad Agri. Res.Station EI·Behera Governorate during 2001 ;2002 seasons . Obtained data revealed that the two fungus formulations Biosect and Biofar were effective against both immature and adult stages of white fly in the field. Reducing the two fungus formulations dose to the half resulted in reducing both Immature and adult stage density of white fly in the field . Mixing the two fungus formulations at the previous doses with Soya bean natural oit Naturals at the dose 625 m!.1100L.water increased the percent reduction of the immature and adult stages Population. Entomopathogens like Biosect and Biofar alone or in mixture with soya bean natural oil gave promising result in controling both adult and immalure stage of white fly and can be safely applied in I.P.M. program of while fly on vegetable plants. | ||||
