| Abstract | ||
| Field application of entomopathogenic nematodes (Heterorhabditis taysariiy (Ht), Heterorhabditis sp (TWF), Heterorhabditis bacteriophora (HP88) and Steinernema carpocapsae (Sc)) against fruit tree borers were performed in 2008 seasons in different governorate. Results showed that the method of use of nematodes soaked cotton plugs gave the best results, followed by the injection method and spray method against Zeuzera pyrina on apple trees. When, controlling Paropta paradoxa the injection method was better than the spraying method of the entomopathogenic nematodes on pear trees. Added the starch polymer to nematode suspension increased the infectivity of the three tested nematode species in both methods of (spray and injection) against Z. pyrina. Results showed that the addition of polymerized starch for the three nematodes tested gave high significant increase amounted 81.01%, while using the nematode alone gave 65.4%. | ||
