The sterile insect technique (SIT) depends greatly on the production of good quality sterile male insects that are released into target wild populations. Quality is assured through a system of bioassays of quality parameters that reflect the insect’s ability to survive, interact with its environment, and locate, mate and fertilize females of the target population. Therefore, implementation of field or field-cage tests under semi-natural conditions, where sterile males have to compete with wild males for wild females, is required to provide the ultimate assurance that the sterile insects have the ability to fulfil their mission after release. For example, low temperature, low nutrient availability, and low quality/quantity of food during the larval development time could have an impact on the adult size and at least reduce his competitiveness within the wild mosquito. Here, using field collected of An. gambiae sl larvae, we will estimate broad-sense biological parameters of the reared mosquito in term of larval developmental time, adult body size, and longevity of starved adults in relation with the type of different larval treatment to screen out the best and benefic for the likely success of the SIT approach. |
