The efficacy of the larvicidal and pupicidal agent (Agnique) MMF was evaluated against larvae of An. arabiensis and Culex (Diptera: Culicidae) under field conditions in Bahary Locality, Khartoum, Sudan. At an applied dosage of 0.25 ml/m2, MMF resulted in 89.4, 79.8 and 88.2% reductions in L3-L4 instars An. arabiensis and 63.5% in Culex larvae (all stages) 24 to 72 hours post-treatment. Pupae were completely eliminated (100%) within 24 hours posttreatment. The earlier instars (L1-L2) of An. arabiensis were more tolerant with a 62.5% reduction at 72 hours post-treatment compared to (L3-L4) instars and pupae. At 7-days post-treatment Agnique gave a 57.5% reduction in L1-L2 and 92.6% in L3-L4 instar larvae of An. arabiensis and 57.3% and 86.4% in Culex larvae and pupae, respectively. We conclude that Agnique can perform effectively against L3-L4 instars and pupae of An. arabiensis for only 1 week, and 3 to 4 days against L1-L2 instars of Culex spp.
在苏丹喀土穆巴哈里地区的野外条件下，评估了杀幼虫和杀蛹剂（阿格尼克）MMF对阿拉伯按蚊和库蚊（双翅目：蚊科）幼虫的效果。以0.25毫升/平方米的施用量施用MMF后，在处理后24至72小时内，阿拉伯按蚊L3-L4龄幼虫减少了89.4%、79.8%和88.2%，库蚊幼虫（各阶段）减少了63.5%。蛹在处理后24小时内被完全消灭（100%）。与L3-L4龄幼虫和蛹相比，阿拉伯按蚊的早期龄期（L1-L2）更具耐受性，在处理后72小时减少了62.5%。在处理后7天，阿格尼克使阿拉伯按蚊L1-L2龄幼虫减少了57.5%，L3-L4龄幼虫减少了92.6%，使库蚊幼虫和蛹分别减少了57.3%和86.4%。我们得出结论，阿格尼克仅能在1周内有效对抗阿拉伯按蚊的L3-L4龄幼虫和蛹，对库蚊属的L1-L2龄幼虫能有效3至4天。
