The residual effectiveness of 0.005mg/ml of cyhalothrin applied to cattle was determined against three species of mosquitos: Anopheles maculatus Theobald. Anopheles dirus Peyton and Harrison Mansonia uniformis Theobald. Twenty-four hour post exposure mortality and the degree of successful blood engorgement were determined by exposing mosquitos for 10 minutes to cattle. Three replicated assays were conducted and mortality determined at 1, 2, 7, 14 and 21 days after each treatment. An initial mortality of 92-94% for An. dirus and Ma. uniformis and 79% for An. maculatus was obtained. Percentage mortality declined to 10%, 18% and 31% for An. maculatus, An. dirus and Ma. uniformis respectively on day 7 post application. On day 21 post application, percentage mortality was 2-3% for the three species of mosquitos.
测定了将0.005毫克/毫升的氯氟氰菊酯施用于牛后对三种蚊子的残留效果：多斑按蚊（Theobald）、大劣按蚊（Peyton和Harrison）以及匀斑曼蚊（Theobald）。通过让蚊子在牛身上暴露10分钟来确定暴露24小时后的死亡率和成功吸血程度。进行了三次重复试验，并在每次处理后的第1、2、7、14和21天测定死亡率。大劣按蚊和匀斑曼蚊的初始死亡率为92 - 94%，多斑按蚊为79%。施药后第7天，多斑按蚊、大劣按蚊和匀斑曼蚊的死亡率分别降至10%、18%和31%。施药后第21天，这三种蚊子的死亡率为2 - 3%。
