Abstract

The potential of a certain Bacillus thuringiensis isolate against first- instar nymphs and newly emerged adults (i.e., sucking stages) of Bemisia tabaci, could be detected on the basis of the calculated LC50 values which recorded 17.7and18.21CFU/ml respectively, This means that, The effect of the bioinsecticide was stronger on adult individuals. On the other hand the calculated LC50 values on newly emerged adults of Euseius scutalis by indirect and direct exposure were 4.89 and 27.5 CFU/ml respectively; this means that indirect exposure was more effective than direct exposure. Biological control agents should be directed to reduce the pest and preserve the predator (natural enemy).
