Temperature influence on embryonic development of Anopheles albitarsis and Anopheles aquasalis.
Temperature influence on the embryonic development of Anopheles aquasalis and An. albitarsis was investigated. At 26 degrees C, 75% and 60% of respectively An. aquasalis and An. albitarsis eggs hatched, with one peak of eclosion, between the 2nd and 3rd day after oviposition. At 20 +/- 2 degrees C, around 66-70% of An. aquasalis eggs hatched, with one eclosion peak, on the 5th day. On the other hand, An. albitarsis eclosion at 21+/- 2 degrees C decreased to 10-22%, with two eclosion peaks, on the 4th-5th day and on the 9th-12th day. These data indicate a stronger temperature influence over An.albitarsis than over An. aquasalis embryos.
