Field and laboratory studies on some compounds against cotton leafworm, spodoptera littoralis (boisd)
Abstract: The cotton leafworm (CLW), Spodoptera littoralis (Boisd.) is 'a highly polyphagous insect pest infesting about 73 host plants including important field crops such as maize, clover, vegetables and various fruits The extensive use of insecticides to control S. littoralis has led to its resistance to the action of various classes of insecticides ( Tabashink et al., 1987), residual toxicity and environmental pollution (Frank et al., 1990) and negative effects on non-target organisms (Franz, 1974). The foregoing problems and hazards that have arisen as a result of using conventional insecticides are incentives for researching alternative control agents with new mode of action. Among these agents are the insect growth regulators (IGRs) and the plant extracts. IGRs are group of insecticides have developed chitin synthesis inhibitors (CSI's) such as Hexaflumuron (consult) and Teflubenzuron (No moult). Many IGR's have shown potentiality against lepidopterous insects including S. littoralis (Farag, 2001 and Abdel-AAl, 2003). This work aimed to evaluate field and laboratory studies of two plant extracts (Azadirachtin A , Soybean seed oil (30%)) and two insect growth regulators Triflumuron (Alsystin,SIR 8514), Flufenoxuron (10% EC) against cotton leafworm, Spodoptera littoralis.
