Abstract
Summary In Mexico, the larvicide temephos (an organophosphate) has been used widely for vector control for a number of yr. Repeated exposure to this larvicide has caused resistance in Aedes container-inhabiting larvae. In this study, the susceptibility status to temephos was evaluated in Ae. albopictus and Ae. aegypti larvae from 4 locales within Quintana Roo, Mexico. Aedes aegypti exhibited low-intensity phenotypic resistance in Cancún, Playa del Carmen, José María Morelos, and Chetumal. Aedes albopictus was found to be susceptible to temephos in Chetumal and Playa del Carmen, but low-intensity phenotypic resistance (tolerance) was observed in Cancún and José María Morelos. The changes in susceptibility status to temephos in both species could be caused by different degrees of exposure to this larvicide. However, more in-depth studies are required to confirm this. Sumario En México, el larvicida temefos (organofosforado) se ha utilizado ampliamente para el control de vectores durante varios años. La exposición prolongada a este compuesto ha provocado resistencia en las larvas del género Aedes. En este estudio, el estado de la susceptibilidad a temefos fue evaluado en larvas de Ae. albopictus y Ae. aegypti de cuatro comunidades de Quintana Roo, México. Aedes aegypti mostró una resistencia fenotípica de baja intensidad en Cancún, Playa del Carmen, José María Morelos, y Chetumal. Por otro lado, las poblaciones de Ae. albopictus de Chetumal y Playa del Carmen fueron susceptibles al larvicida, sin embargo, se observó resistencia fenotípica de baja intensidad en Cancún y José María Morelos. Los cambios en el estado de susceptibilidad a temefos de ambas especies puede deberse a los diferentes niveles de exposición al larvicida, sin embargo, se requiere de estudios más profundos para confirmarlo.
综上所述,在墨西哥,Temephos(一种有机磷酸盐)已被广泛用于许多年的媒介控制。反复接触这种Larvice在Aedes容器中引起了耐药性-居住的幼虫。在这项研究中,评估了墨西哥金塔纳罗4个地方的AE.Alboctitus和AE.Aegypti幼虫对Temephos的易感性状况。埃及伊蚊在坎昆、卡门海滩、何塞·玛丽亚·莫雷洛斯和切图马尔表现出低强度的表型抵抗。在Chetumal和Playa del Carmen发现白纹伊蚊容易感染temephos,但在坎昆和何塞·玛丽亚·莫雷洛斯观察到低强度的表型抵抗(耐受性)。这两个物种对特米芬的易感性状态的变化可能是由于接触这种Larvice的程度不同造成的。然而,需要进行更多的深入研究来证实这一点。在墨西哥,几年来,Temefos(有机磷)Larvicida已广泛用于病媒控制。长期接触这种化合物会导致伊蚊属幼虫产生耐药性。在这项研究中,评估了墨西哥金塔纳罗四个社区的白纹伊蚊和埃及伊蚊幼虫对Temefos的易感性状况。埃及伊蚊在坎昆、卡门海滩、何塞·玛丽亚·莫雷洛斯和切图马尔表现出低强度的表型抗性。另一方面,Chetumal和Playa del Carmen的白纹伊蚊种群对Larvicida敏感,但在坎昆和何塞·玛丽亚·莫雷洛斯观察到低强度的表型抗性。两个物种对Temefos的易感性状态的变化可能是由于接触Larvicid的程度不同,但需要进行更深入的研究来证实这一点。
