Effect of three insect growth regulators on some biological and physiological aspects of spodoptera littoralis (boisd.)
Abstract: Cotton plants have been infested by many pests specially cotton leaf worm, Spodoptera littoralis (Boisd.) which led to great crop loss. The control of this pest is based mainly on foliage treatments with several traditional insecticides. The extensive and continuous use of such insecticides has created many problems, mainly the incapability of toxic agents in controlling the target insect pest at the recommended doses. Therefore, insecticides with novel modes of action with high selectivity towards vertebrates, such as insect growth regulators (IGRs) are required. This group of insecticides has developed and classified into (i) chitin synthesis inhibitors (CSI's) like Hexaflumuron (consult) and Teflubenzuron (No moult) and (ii) juvenile hormone mimics or ecdysone agonist (molting accelerating compounds) such as Tebufenozide (MAC). IGR's act by altering normal insect growth patterns, eventually and indirectly resulting in death of treated insects (Chandler et al., 1992). Many IGR's have shown potentiality against lepidopterous insects including S. littoralis (Ahmed et al., 1990; El-Deeb et al., 1991; Abdalla and Sammour, 1992; Fisk and Wright, 1992; Rao et al., 1994; Sokar, 1995; Auda and Salem, 1997; Farag, 2001 and Abdel-Al, 2003 and Seth et al., 2004). The aim of present work is to evaluate three IGRs against S. littoralis by studying their toxicity, and their efficacy on certain biological aspects as well as on feeding, consumption, digestion and utilization of treated cotton leaves by S. littoralis larvae.
