Experimental breeding sites simulating natural conditions were used to evaluate the efficacy of 2 formulations of Bacillus sphaericus (strain 2362) against Anopheles albimanus and culicine (mostly Culex coronator and Cx. quinquefasciatus) mosquito larvae of southern Mexico. Three doses of each formulation were used in a first field trial: 2, 3 and 4 g/m2 (granular) or 2, 3 and 4 ml/m2 (liquid); and in a second field trial: 0.125, 0.24 and 0.5 g/m2 (granular) or 0.125, 0.25 and 0.5 ml/m2 (liquid). The optimum concentrations of each formulation for effective control of larval populations over periods of 3-4 months were 0.125 ml/m2 of liquid product for Culex spp. and 2 g/m2 of granular product for An. albimanus (ca. 70% mean reduction).
利用模拟自然条件的实验性繁殖地，评估了球形芽孢杆菌（菌株2362）的两种制剂对墨西哥南部的白纹伊蚊以及库蚊（主要是冠突库蚊和致倦库蚊）幼虫的防治效果。在首次田间试验中，每种制剂使用了三个剂量：2、3和4克/平方米（颗粒剂）或2、3和4毫升/平方米（液剂）；在第二次田间试验中：0.125、0.24和0.5克/平方米（颗粒剂）或0.125、0.25和0.5毫升/平方米（液剂）。在3至4个月的时间内，有效控制幼虫种群的每种制剂的最佳浓度为：库蚊属幼虫使用0.125毫升/平方米的液剂产品，白纹伊蚊使用2克/平方米的颗粒剂产品（平均减少约70%）。
