摘要：
12 water and/or mud samples from different mosquito habitats were tested for the presence of phages specific to Bacillus spp. 37 plaque morphologies were detected on B. thuringiensis. H-14, B. thuringiensis Berliner, B. sphaericus 1593, B. sphaericus IF-114. Samples number 1, 11, 12, 5 and 10 decreased the mortality rates of B. thuringiensis H-14 when added to the larvicidal bioassay system of Culex pipiens. Samples number 5, 11, 9, 12 inhibited the larvicidal activity of B. sphaericus. Ultrafiltrates of water samples, which harbored high numbers of the detected phages exerted more inhibition in the larvicidal potentiality of the tested entomopathogenic bacteria.
