Abstract: As part of the rearing process for Anopheline mosquitoes, a new method for accurate delivery of food to mosquito larvae was evaluated by the Armed Forces Research Institute of Medical Sciences (AFRIMS) Thailand. Larvae were fed using AFRIMS spoons or a standard salt shaker, and larval developmental time, mortality, adult size, and food remnants remaining in the larval rearing water were evaluated. The food quantity delivered by the spoons to Anopheles dirus and An. minums larvae (0.27, 0.18 g/day, respectively) was less than that from the salt shaker (2.20, 0.36 g/day, respectively). Larval development time was not affected by the different amounts of daily food. However, using the AFRIMS spoons lowered the overall mortality rates, produced larger females, reduced food remnant contamination of the rearing water, and improved mosquito production in the insectary. This food delivery method may be of benefit to other insectaries seeking to maximize their mosquito production.
Weight of food debris obtained from the larval rearing water. Mean values followed by the same letter are not significantly different from one another (<em>P</em>>0.05, Tukey’s honestly significant test).
