Abstract

Soil samples from some agricultural research plantations (IITA, CRIN, IAR&T, NIHORT and FRIN) in Ibadan metropolis, Nigeria were screened for the presence of entomopathogenic strains of Bacillus species. The loamy-sand and sandy-loam soil types were typical soil texture of these locations with soil pH ranging between 4.9 and 6.1. The loamy-sand soil type recorded the highest number of Bacillus spp. and the history of pesticides applied on the sampling locations did not seem to affect the distribution of Bacillus thuringensis and other entomopathogenic Bacillus spp. in the different soils. Eighty-two strains of Bacillus spp. were isolated with only seven of these being entomopathogenic. The seven strains of Bacillus spp. were toxic to Anopheles mosquito larvae exhibiting between 5% and 15% mortality within 72h.
