Abstract

Abstract

Six genera, comprising 13 species of mosquitoes, which were found indigenously in Thailand, ie, Aedes albopictus, Ae. lineatopennis, Ae. mediolineatus, Ae. togoi, Anopheles barbirostris, An. maculatus, An. minimus, An. peditaeniatus, An. sinensis, Armigeres subalbatus, Culex quinquefasciatus, Mansonia uniformis, and Toxorhynchites splendens, were screened for synchronized oviposition by placing 5-day-old gravid females on a moist filter paper plate for 1 hour. This revealed that Ae. albopictus, Ae. lineatopennis, Ae. mediolineatus, Ae. togoi, and Ar. subalbatus could succeed in depositing a satisfactory number of viable eggs within 1 hour. The oviposition rates, average number of eggs per oviposited female, and hatchability rates were 90.0%, 19.4, and 67.3%; 60.0%, 16.0, and 55.7%; 35.0%, 25.4, and 42.7%; 65.0%, 56.2, and 75.0%; 55.0%, 62.4, and 82.0%; per species, respectively.
