Effect of temperature on the development of Aedes aegypti and Aedes albopictus

Abstract

The fundamental approach to the biological control of Aedes albopictus requires the mass rearing of mosquitoes and the release of highly competitive adults in the field. As the fitness of adults is highly dependent on the development of immatures, we aimed to identify the minimum feeding regime required to produce viable and competitive adults by evaluating three response parameters: development duration, immature mortality, and adult wing length. Our study suggests at least 0.60 mg/larva/day of larval diet composed of dog food, dried beef liver, yeast, and milk powder in a weight ratio of 2:1:1:1 is required to maximize adult fitness. With standardized protocols in mass rearing, intensive studies can be readily conducted on mosquito colonies to facilitate comparisons across laboratories. This study also evaluated the differences in response of laboratory and field strains under different feeding regimes. We found that strain alone did not exert substantial effects on all response parameters. However, the field strain exhibited significantly lower immature mortality than the laboratory strain under the minimum feeding regime. Females and males of the laboratory strain had longer wing lengths under nutritional constraint due to the higher mortality that resulted in reduced interactions with the remaining larvae. Meanwhile, the field strain exhibited heterogeneous duration of immature development compared with the laboratory strain. The disparities demonstrated by the two strains in this study suggest the effect of inbreeding surfaced after a long term of laboratory colonization. Despite the trade-offs resulting from laboratory colonization, the competitiveness of the laboratory strain of Ae. albopictus is comparable to the field strain, provided the larvae are fed optimally.

“…Previous studies have identiÞed similar average temperatures ranging from 4.2 to 11ЊC prevent the development of immature Ae. albopictus (Udaka 1959, Kamimura et al 2002, Delatte et al 2009). …”

Environmental conditions in water storage drums and influences on Aedes aegypti in Trinidad, West Indies

“…Larval rearing temperatures can potentially have a major impact on disease transmission by influencing body size, development time, and production (Kierans and Fay, 1968; Atkinson, 1994; Kamimura et al , 2002; Reisen et al , 1997). The relationship between elevated temperatures and shortened development duration, could increase the abundance of host seeking adults (Kamimura et al, 2002; Keirans and Fay, 1968).…”

“…aegypti, and subsequently dengue transmission. Mosquito body size is dependent upon intrinsic genetic factors as well as larval nutrition and temperature during development has been correlated with vector competence (Alto et al ., 2008; Kierans and Fay, 1968; Kamimura et al ., 2002; Reisen et al ., 1997). Understanding their effects on mosquito populations is important to the development of novel control programs.…”

A Model to Predict Evaporation Rates in Habitats Used by Container-Dwelling Mosquitoes

“…To determine developmental rates for Ae. albopictus, temperaturedependent rates were estimated from the literature (Hawley 1988, Alto and Juliano 2001, Kamimura et al 2002, and Delatte et al 2009). Developmental rates also were calculated for Cx.…”
