(S.) anduzei, S. (S.) jobbinsiの2属5種が採集された。G. wrightiとS. (E.) sp.は特に個体数が多く, この2種の合計はそれぞれの川の総採集個体数の80%以上を占めた。採集された5種の個体数密度は雨季の始まりから乾季の前半まで高く, 乾季の後半は低い。各月の幼虫の頭幅値の頻度分布から, G. wrightiは雨季に2世代, 乾季に1世代, 計年3世代, S. (E.) sp.は雨季乾季共に2世代ずつ, 計年4世代経過するものと考えられる。 Immature stages of blackflies were studied in uppermost part of 2 streams in Guatemalan highland, Sierra Madre. In total 5 species, Gigantodax wrighti, Simulium (Simulium) tricornis, S. (S.) anduzei and S. (S.) jobbinsi in descending order of abundance, were collected. G. wrighti and S. (E.) sp. were predominant and occupied more than 80% of the total specimens collected from each stream. All the 5 species appeared at higher density in the rainy season and the first half of the dry season than in the latter half of the dry season. From the head width distribution in each month, G. wrighti and S. (E.) sp. were found to be multivoltine species. G. wrighti had two generations in the rainy season to the first half of the dry season and possibly one generation in the latter half. S. (E.) sp. had 2 generations in the rainy season, and at least one more generation, possibly two, in the dry season., 金沢大学留学生センター}, pages = {301--308}, title = {グァテマラ共和国の高原のブユとその個体数密度の季節変動および化性}, volume = {32}, year = {1981} }
