Abstract：
Indoor and outdoor ovitraps were placed in 15 randomly selected houses in two rural villages in Chiapas, southern Mexico. In addition, ovitraps were placed in five transects surrounding each village, with three traps per transect, one at the edge, one at 50 m, and another at 100 m from the edge of the village. All traps were inspected weekly. A transect with eight traps along a road between the two villages was also included. Population fluctuations of Aedes aegypti and Ae. albopictus were examined during 2016-2018 by counting egg numbers. A higher number of Aedes spp. eggs was recorded at Hidalgo village with 257,712 eggs (60.9%), of which 58.1% were present in outdoor ovitraps and 41.9% in indoor ovitraps, compared with 165,623 eggs (39.1%) collected in the village of Río Florido, 49.0% in outdoor and 51.0% in indoor ovitraps. A total of 84,047 eggs was collected from ovitraps placed along transects around Río Florido, compared to 67,542 eggs recorded from transects around Hidalgo. Fluctuations in egg counts were associated with annual variation in precipitation, with 2.3 to 3.2-fold more eggs collected from ovitraps placed in houses and 4.8 to 5.1-fold more eggs in ovitraps from the surrounding transects during the rainy season than in the dry season, respectively. Aedes aegypti was the dominant species during the dry season and at the start of the rainy season in both villages. Aedes albopictus populations were lower for most of the dry season, but increased during the rainy season and predominated at the end of the rainy season in both villages. Aedes albopictus was also the dominant species in the zones surrounding both villages. The numbers of eggs collected from intradomiciliary ovitraps were strongly correlated with the numbers of eggs in peridomiciliary ovitraps in both Río Florido (R2
adj = 0.92) and Hidalgo (R2
adj = 0.94), suggesting that peridomiciliary sampling could provide an accurate estimate of intradomiciliary oviposition by Aedes spp. in future studies in these villages. We conclude that the feasibility of sterile insect technique (SIT)-based program of vector control could be evaluated in the isolated Ae. aegypti populations in the rural villages of our baseline study.
摘要：
室内和室外产卵器被放置在恰帕斯州两个农村随机选择的15所房屋中，墨西哥南部。此外,诱卵器被放置在每个村庄周围的五个剖面中，每个横断面有三个陷阱，一个在边缘，一个在50米，另一个距离村庄边缘100米。每周检查所有陷阱。还包括两个村庄之间一条道路上有八个陷阱的横断面。埃及伊蚊和Ae的种群波动。在2016-2018年期间，通过计数卵数检查了白纹目。伊蚊数量较多。伊达尔戈村的鸡蛋记录为257,712个鸡蛋（60.9%），其中58.1%存在于室外产卵器中，41.9%存在于室内产卵器中，与RíoFlorido村收集的165,623个鸡蛋（39.1％）相比，室外产卵器占49.0%，室内产卵器占51.0%。从沿着RíoFlorido周围的样片放置的诱卵器中收集了总共84,047个卵，相比之下，从伊达尔戈周围的样带记录的67,542个鸡蛋。卵数的波动与降水量的年变化有关，雨季期间从房屋中放置的产卵器中收集的卵比旱季多2.3至3.2倍，从周围样带中收集的产卵器中收集的卵比旱季多4.8至5.1倍，分别。埃及伊蚊是两个村庄在旱季和雨季开始时的主要物种。在旱季的大部分时间里，白纹伊蚊种群数量较低，但在雨季期间有所增加，并在两个村庄的雨季结束时占主导地位。白纹伊蚊也是两个村庄周围地区的优势物种。在RíoFlorido（R2adj=0.92）和Hidalgo（R2adj=0.94）中，从内部睫状卵器中收集的卵的数量与周围睫状卵器中的卵的数量密切相关，这表明，脂质周围的采样可以为伊蚊属的脂质内产卵提供准确的估计。在这些村庄的未来研究中。我们得出的结论是，可以在分离的Ae中评估基于不育昆虫技术（SIT）的媒介控制程序的可行性。我们基线研究农村村庄的埃及伊蚊种群。
