Influence of biotic factors on ingestion and developtment of Aedes aegypti and Aedes albociptus larvae (Diptera:Culicidae)
Chinese Journal of Entomology 12 (1), 41-48
Abstract: The effects of age, larval density and starvation on food ingestion and development of Aedes aegypti (L.)and Aedes alboptictus (Skuse) were studied. Following the increasing of larval age and feeding period, the food displacement rates of both species were reduced. There was a significant decrease (p < 0.05) in food ingestion when the 4th instar larvae of both species were starved for more than 12 hours. A high pupation rate (28.6%) with Ae. aegypti larvae was found to result in compensation for the 48 hours starvation. The study on the influence of density indicated that shorter larval duration, more pupated individuals and higher pupal weight can be obtained when both species are reared in a density of 20 larvae/100 ml water. According to the adaptative index [(pupal weight / larval duration)x% survival], Ae. aegypti is more adaptable to a low density environment, while Ae. albopictus is more adaptable to overcrowding.
