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.

墨西哥南部两个乡村的埃及伊蚊和白纹伊蚊种群动态：昆虫不育技术评估的基线数据

在墨西哥南部恰帕斯州两个乡村的 15 个随机选择的房屋中放置了室内和室外产卵器。此外，在每个村庄周围的5个样带上放置了产卵器，每个样带3个，1个在边缘，1个在距村庄边缘50 m处，1个在距离村庄边缘100 m处。每周检查所有陷阱。两个村庄之间的道路沿线有八个陷阱的横断面也包括在内。埃及伊蚊和伊蚊的种群波动。2016 年至 2018 年期间，通过计算卵数量对白纹伊蚊进行了检查。伊蚊数量较多。伊达尔戈村记录了 257,712 个鸡蛋（60.9%），其中 58.1% 存在于室外诱产卵器中，41.9% 存在于室内产卵器中，而里奥弗洛里多村收集到 165,623 个鸡蛋（39.1%），其中 49.0% 存在于室外室内诱产卵器中为 51.0%。从沿着里奥弗洛里多周围横断面放置的产卵器中总共收集了 84,047 个卵，而伊达尔戈周围横断面记录了 67,542 个卵。鸡蛋数量的波动与降水量的年度变化有关，雨季期间从放置在房屋内的产卵器中收集到的卵多于旱季的 2.3 至 3.2 倍，而从周围样带中收集的卵则多于旱季的 4.8 至 5.1 倍。分别。埃及伊蚊是两个村庄旱季和雨季开始时的优势物种。白纹伊蚊的数量在旱季大部分时间都较低，但在雨季有所增加，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边地区的优势种。^{在里约弗洛里多 (R 2} _adj = 0.92) 和伊达尔戈 (R ² _adj = 0.94)中，从圈内产卵器收集的卵数量与圈内产卵器中的卵数量密切相关，这表明圈内取样可以提供准确的估计值。伊蚊属的室内产卵。未来在这些村庄的研究。我们的结论是，基于昆虫不育技术（SIT）的病媒控制方案的可行性可以在分离的伊蚊中进行评估。我们基线研究中农村的埃及人口。
