True spiders represent one of the most important natural predatory species in Egyptian fields. In this work, common true spiders were surveyed in wheat, cotton and maize fields, and were counted weekly by using the direct method. For evaluating the feeding consumption of true spiders, five feeding cases were tested (as preys). These cases were: egg...

Infection with the entomopathogenic nematode, Steinernema glaseri caused death to the Egyptian cotton leaf worm, Spodoptera littoralis (Boisd.) larvae. Mortality of insect larvae increased when the nematodes were exposed to eicosanoid biosynthesis inhibitor dexamethasone. These effects were reversed when dexamethasone was used together with the eic...

The entomopathogenic nematodes, Heterorhabditis and Steinernema together with their associated bacteria Photorhabdus and Xenorhabdus, respectively have come about because of their biological control potentials. To address the immunocompetence of the host insect Schistocerca gregaria following nematode infection, we tested a hypothesis that the inse...

The nematode isolates tested were collected from different localities of Egypt. Some experiments evaluated the infectivity and susceptibility of Heterorhabditis bacteriophora and H.indica as biocontrol candidates against some economics agricultural insect pests, such as Spodoptera littoralis, Agrotis ipsilon, Sesamia cretica, Phthorimaea operculell...
