Effect of food type in response to different roles of fig figs and raisins for some insect growth inhibitors

The result of the recent study revealed that the host kind (Artificialdiet, Date and Fig) affect the Susceptibility of different insect stages ofFig moth Ephestia caute/la (Walk.) and CmTant moth Ephestia ca/ide/la(Gunee) to selected insect growth inhibitors (Diflubenzuron , Lufenuron,Cyromazine) Lufenuron was the most toxic inJ1ibitors against eggs of Figmoth reared on artificial diet and its LC50 value reached 0.0012 whilethe Cyromazine exhibit a less toxic effect on eggs of the same speciesreared on Fig and its LC 50 value reached 0.0075. The larvae ofFig mothshowed a higher sensitivity to insect growth inJ1ibitors in comparison toCurrant moth larvae reared on all hosts. The values of LC50 of insectgrowth inhibitors on pupae of Fig and currant most were varied accordingto the diet kind and insect species. Diflubenzuron and Cyromazine weremore toxic to the adults of Fig moth reared on artificial diet whileCyromazine showed a higher toxic effect to the adults of Cunant mothreared on fig.
