The effect of intercropping broad bean with termis on the corresponding pest infestation and predators abundance in El-Menofia Governorate, Egypt [electronic resource].

Includes reference.

Field trials were conducted at Ashmoun region, EI-Menofia Governorate during the two broad bean cultivated seasons 2005/2006 and 2006/2007 fbr studying the impact of intercropping of broad bean with termis on pest infestation and the related predators. The intensity of attack to broad bean differed greatly during the two growing seasons based on cropping pattern. It appears that termis is a preferable host had decreased aphids and spider mites population but increased the population of whitefly under different tested intercropping systems during the tested seasons. Also Termis showed alone less attractive than broad bean to jassids infestation. The population of the collected predaceous insects showed light increase under intercropping systems of broad bean with termis in 2005/2006 than 2006/2007 season. Highly significant values for the effect of system to the related predaceous insects abundance, but the interaction between systems and the tested seasons demonstrates reliable effect. The number of predaceous mites (Phytoseiidae and Tydeidae) was obviously higher on leaflets of broad bean intercropped fields with termis than in pure broad bean. The intercropping system for broad bean with termis also increase the abundance of spiders which were belonging to six dominanted families, namely Miturgidae,Thomisidae, Philodromidae, Salticidae, Theridiidae and Gnaphosidae.
