Integral Action of Metarhizium Anisopliae Var. Acridun and Low Dose of Some Affecting Treatments Against Locusta Migratoria Migratorioides Under Field Conditions

Abstract

The effect of Metarhizium anisopliae var. acridum, anti-feedant agent (azadirachtin), anti-molting agent (Flufenoxuron), Juvenile hormone analogue compound (pyripoxyfen) and Chloropyrifos (two formulations) was evaluated under field conditions of Shark El-Uwainat area against the nymphal instars 3 rd , 4 th and 5 th of Locusta migratoria migratorioides. The obtained results revealed that the integration between M. anisopliae and 20% of the recommended dose of all the compounds exhibited the highest integral action, recording 100% population reduction after (11-13days) of application. On the other hand, the fungus alone induced moderate percentages of population reduction after 10 days of treatment. Also, on comparing the dose and half the dose of the fungus the full dose gave approximately the same trend of activity. Green muscle (M. anisopliae), antifeedant agent, anti-molting agent and juvenile hormone analogues compound can be useful for proposed different elements of an IPM strategy.
