Subject(s): Online resources: In: Bulletin of The Entomological Society of Egypt (A.R.E.), Economic Series 2005.v.31Summary: Tomato, Lycopersicon esculentum is considered an important vegetable crop in Egypt. Tomato plants are infested by many pests such as the aphid, Aphis gossypii, the whitefly, Bemisia labaci, the Egyptian cotton leaf worm, Spodoptera littoralis, the potato tuber worm, Phlhorimaea operculella and the American bollworm, Heliolhis armigera (Anonyomus, 2001). Both chlorpyrifos-methyl and profenofos are used in controlling these insects. Using insecticides could contaminate tomato fruits and cause hazard to consumers. Many publications revealed the existence of pesticide residues, mainly organophosphorus insecticides in tomato fruits, (El-Sayed, el al., 1971; Gomaa, el al.1985; Ramadan 1991; EINabarawy ,el al.1992; Abdalla, el al., 1993 and Sallam1998).
