Spore-forming Bacillus isolates were recovered from different Jordanian habitats. Of 37 samples, 187 colonies were selected. Forty-six (24.6%) of them were pathogenic to the third instar larvae of Drosophila melanogaster. Larvicidal activity of the isolates was from 0% (non-cultivated soil) to 83.3% (decomposed animal residues). The total spore count per gram weight varied from 0.1 x 10(5)-18 x 10(5) among the 37 tested samples. Morphological and microscopical identification of the isolates showed the presence of 16 different Bacillus species. The pathogenic isolates were B. thuringiensis (44) and B. sphaericus (2).
从约旦不同栖息地分离出了形成芽孢的芽孢杆菌。在37个样本中，挑选出了187个菌落。其中46个（24.6%）对黑腹果蝇的三龄幼虫具有致病性。这些分离株的杀幼虫活性从0%（未耕种土壤）到83.3%（分解的动物残体）不等。在37个测试样本中，每克重量的总芽孢数在0.1×10⁵至18×10⁵之间变化。对分离株的形态学和显微镜鉴定显示存在16种不同的芽孢杆菌。致病分离株为苏云金芽孢杆菌（44个）和球形芽孢杆菌（2个）。
