Can we release dragonflies to control mosquitoes in Singapore?
Frequently Asked QuestionsDragonflies are one of the predators of mosquitoes and have been deployed as biological control agents in rural areas in countries such as Cambodia and Vietnam. However, their extent of control is limited in Singapore due to the lack of larvae habitat (i.e. pond) and difference in adult behaviour and habitat. EHI has tested several commercial adult mosquito traps of various designs (baited with a range of attractants, including carbon dioxide) for surveillance and research purposes.
Related QuestionsCan I use Dragonflies to control mosquitos or other flying pests?
British Dragonfly SocietyDragonflies certainly do eat large numbers of flying pest species, but using them to control these pests is not really feasible. There have been a number of studies carried out and only in very restricted and tightly controlled environments have Dragonflies, or their larvae, been shown to be able to control pest numbers. In the open, there is no reason to suppose that Dragonflies introduced to a pest rich habitat will stay there.
