A survey of Bacillus thuringiensis recovered from the environments of olive groves in Greece was carried out. Of 80 soil samples, 24 were found to contain B. thuringiensis with parasporal crystal inclusions; these were tested for toxicity against the olive fruit fly (Dacus oleae). Mortality levels of larvae caused by the different isolates varied from 7 to 87%. Higher levels of mortality were observed if a mixture of relatively pure crystals and spores was used compared with the mortality resulting from either fraction alone. We were able to show that the toxicity of the most active isolate is likely to be specific for D. oleae.
对从希腊橄榄园环境中分离出的苏云金芽孢杆菌进行了一项调查。在80份土壤样本中，发现有24份含有带有伴孢晶体包涵体的苏云金芽孢杆菌；对这些样本进行了针对橄榄实蝇（Dacus oleae）的毒性测试。不同分离株引起的幼虫死亡率从7%到87%不等。与单独使用其中任何一种成分相比，使用相对纯净的晶体和孢子混合物时观察到更高的死亡率。我们能够证明，活性最高的分离株的毒性可能对橄榄实蝇具有特异性。
