Insecticides are important in agriculture, to reduce human disease, and to decrease the nuisance of biting insects. Despite this, many have the potential for environmental impacts and toxicity in nontarget organisms. We reviewed data on the effects of insecticides based on toxins from Bacillus thuringiensis var. israelensis (Bti) and Bacillus thuringiensis var. kurstaki (Btk) on amphibians. The few peer-reviewed publications that are available for Bti provide variable conclusions, ranging from few observable effects to evidence of acute toxicity at high concentrations. We briefly highlight the current controversies and identify key areas for future investigation.

杀虫剂在农业中很重要，可减少人类疾病并减少咬虫的滋扰。尽管如此，许多物质仍可能对非目标生物产生环境影响和毒性。我们审查了基于苏云金芽孢杆菌变种的毒素对杀虫剂作用的数据。以色列（Bti）和苏云金芽孢杆菌变种 库尔斯塔基（Btk）两栖动物。少数可用于Bti的经过同行评审的出版物提供了不同的结论，从可观察到的影响到高浓度下急性毒性的证据不等。我们简要介绍了当前的争议，并确定了需要进一步研究的关键领域。
