Ciclos de vida comparados de Aedes aegypti (Diptera, Culicidae) do semiárido da Paraíba

Abstract: ABSTRACT. Life cycles compared to Aedes aegypti (Diptera, Culicidae) in the semi-arid region of Paraíba. The present work aims at comparing the life cycle between samples from different populations of Aedes aegypti (Linnaeus, 1762) collected in ten municipalities in the semi-arid region of state of Paraíba, Brazil. The life cycles were studied under 26 ± 2°C, a relative humidity of 60 ± 10% and a 12 h photophase. The development period, egg viability, and larval and pupal survival, were evaluated daily, as wel… Show more

“…Our finding of prolonged times in both larvae and pupae development in three populations is not rare since, for example, larval development times in populations of Ae. aegypti with ranges from 9.15 to 10.89 days have been reported, similar to what we found for Riohacha [ 37 ]. These long development times may represent a disadvantage since larvae and pupae are exposed longer to predators and other factors that can eliminate them and, therefore, may influence the behavior of these populations in the field [ 92 , 93 , 94 ].…”

“…The ability of Ae. aegypti to vary its biology and adapt to different environmental conditions can influence population densities, favoring its permanence in areas with virus transmission [ 37 , 38 ]. Thus, Ae.…”

“…The transience of breeding grounds, conditioned by the presence of water, necessitates rapid development of the larval and pupal stages, because the need for the cycle to be complete prior to evaporation of the water-containing vessel (CONSOLI and OLIVEIRA, 1994). The development cycle of Ae.aegypti is holometabolous, involving egg phases (resistant up to 450 days), four larval stages (from seven to nine days) and pupa (two to three days), being the temperature a relevant factor in its development, that is, at high temperatures the life cycle of the mosquito is faster (CASTRO et al, 2013;LOPES et al, 2014) and the females lay the eggs in batches of 50 to 500 eggs (CONSOLI and OLIVEIRA, 1994). Ae.…”

“…Há uma concentração deste mosquito nas vilas e cidades, onde há um maior contingente populacional, onde as condições ambientais e sociais contribuem para o estabelecimento de suas populações, embora também possa ser encontrado distante dos aglomerados urbanos (Consoli;Oliveira, 1994;Natal, 2002). O estudo com as diferenças de ciclos biológicos verificadas entre as populações de A. aegypti apresenta capacidade desse inseto sofrer variações na sua biologia e se adaptar às diferentes condições ambientais, favorecendo a permanência deste nessas áreas com aumento do risco de transmissão do vírus da dengue (Castro JR et al, 2013).…”
