| Abstract | ||
| Some Systematic Insecticides were subjected to field bioassay to evaluate its efficacy to control leaf miner of apple Phyllonorycter blancardella and to know their effect on its Parasitoids.The insecticides were Methomate -90WP, Wide 20 SP, Actara 25 WG (1, 5 and 10 gm /20 L). Results revealed that both applied concentrations (5 and 10 gm /20 L) of wide and Actara showed high field efficacy in reducing density of the pest after five and ten days of spray. So results indicated that the concentration (5 gm /20 L) was more efficient in reducing the numbers of sap feeder larvae( first three of five instars) after five days of spray while the concentration (10 gm /20 L) after ten days was more efficient in reducing the numbers of tissue feeder larvae (4th and 5th instars). This study has also proved that Actara was more safety on hymenopterous Parasitoids contrast with Methomate and Wide that have negative effect on it. Actara was integrated with Parasitoids in reducing the density of this insect while Methomate was less efficient on this pest and more toxic on its Parasitoids. | ||
