The deleterious effects of plant extracts or pure compounds on insects can be manifested in several manners including toxicity, repellent, antifeedant growth inhibitor, suppression of reproductive behavior and reduction of fecundity and fertility. Different types of plant preparations such as powders, solvent extracts, essential oils and whole plants are being investigated for their insecticidal activity including their action as fumigants, repellents, antifeedants, anti-ovipositions and insect growth regulators. The Egyptian woody perennials, Ipomea carnea belongs to family Convolvulaceae;...

This work provides an integral review of biology, toxicity and biochemical responses of some insecticides belonging to different groups on the cotton leafworm, Spodoptera littoralis (Boisduval) known as a destructive polyphageous insect pest that attack a wide range of crops especially cotton plants throughout the world attaining huge economic losses particularly in Egypt, under laboratory and field conditions and their subsequent side effects against some common predators associated with this pest in field. Moreover, using surfactants to increase the efficiency of some selected groups...

The complexity of Heliothis and Helicoverpa population dynamics, host relations and they large differences between the agroecosystems and socioeconomic environments in which they are pests, make generalized attempts on management largely meaningless. The pest and their impact need also to be understood in a regional context and management strategies develop on this basis. On the pages of this manuscript we try to throw some light on different sides related to this pest which already been published by other authors across time in an attempt to gather information and reviews in sole review...

This book is an attempt lead to historiography, monitor and record what has already published for Scrobipalpula absolta (Myrick, 1917) = Tuta absoluta (Povolny, 1994) insect which attacked the cultivations of tomatoes in various parts of the world and rapidly colonoised vast areas of different continents became a key problem in both outdoor and greenhouse crops unrealized losses for the growers, so we collected these review data and classified according to the subject for the benefit of the reader and whom interest in this regard to construct the integrated idea of this pest as well as...
