Temperature
influence on the embryonic development of
Anopheles aquasalis
and An.
albitarsis
was investigated.
At 26ºC, 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 ± 2ºC, 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 ± 2ºC 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.
