ISOLATION AND IDENTIFICATION OF NOVEL LOCAL ISO- LATES OF Bacillus thuringiensis ACTIVE AGAINST RED PALM

he gram-positive bacterium B. thuringiensis is well-known as sources of insecticidal proteins, most of which accumulate in crystalline inclusions during sporulation, these parasporal inclusions contain various types of insecticidal crystal protein (ICP). The crystal proteins from B. thuringiensis are among the most successful biological control agents for the suppression of agriculturally and medically important insect pests (Roh et al., 2007), being toxic to the larvae of lepidopteron, dipteran, and coleopteran insects (Johnson et al., 1998), as well as certain hymenoptera, homoptera, and mallophaga, in addition to many nematodes, flatworms, and Sarcomastigophora (Walters and English, 1995; Horak et al., 1996).
