摘要

摘要埃及伊蚊(Diptera:Culicidae)由于其传播的节肢动物传播病毒(虫媒病毒),对人类的福祉和健康构成了严重威胁。它的控制主要是通过大规模应用针对幼虫和成虫阶段的杀虫剂来实现的。为了开发一种对抗这种媒介的额外方法,将卵(7-15天大)以20只为一组暴露在温度在32±2°C和147±2°C.之间的热空气流中5 s。记录处理后24小时和48小时出现幼虫的累积百分比,作为对热空气处理反应的测量。在暴露于室温(26±2°C)的未经处理的对照中,幼虫在48小时内的累计羽化率为99.2±1.7%。幼虫在48 h内的累积羽化率在87±2°C.97.2%到147±2.4°C.67.7%之间。因此,这种拟议的热空气处理的生物学效果是不可接受的。埃及伊蚊卵在耐热和干燥方面的自然生物学特性似乎保护了它们免受不同温度水平的测试。

Larval Emergence from Aedes aegypti (Diptera: Culicidae) Eggs Exposed to Hot Air
Abstract Aedes aegypti (L.) (Diptera: Culicidae) represents a severe threat to human well-being and health due to the arthropod-borne viruses (arboviruses) it transmits. Its control is implemented mainly through massive applications of insecticides directed to the larval and adult stages. To develop an additional method for combating this vector, eggs (7–15 d old) were exposed in groups of 20 to a stream of hot air at temperatures between 32 ± 2°C and 147 ± 2°C for 5 s. The cumulative percentage of emerged larvae at 24 h and 48 h posttreatment was recorded as a measure of response to the hot air treatment. In the untreated control, which was exposed to room temperature (26 ± 2°C), the cumulative emergence of larvae at 48 h was 99.2 ± 1.7%. The cumulative percentage of larval emergence at 48 h ranged from 97.2% at 87 ± 2°C to 67.7% at 147 ± 2.4°C. The biological efficacy of this proposed hot air treatment was, thus, not acceptable. The natural biological attributes of the Ae. aegypti eggs in withstanding heat and desiccation appear to have protected them against the various levels of temperature tested.
