INTEGRATED PEST MANAGEMENT – DRAGONFLY POND PROJECT Tropicana pioneers the use of dragonflies as a biocontrol mechanism. As one of the country’s leading developers, Tropicana is the first to deploy dragonflies to control pests naturally in Tropicana Golf & Country Resort. The pilot project to release 88 larvae of Red Glider Dragonfly (Tramae transmarina) into a new man-made pond in TGCR on 24 September 2021 is a collaboration with well-known dragonfly expert Dr Choong Chee Yen from Universiti Kebangsaan Malaysia (“UKM”). Our Dragonfly Pond is a flagship project to breed and sustain a healthy dragonfly population at our golf course as a means to apply biological control to mosquitoes in the surrounding area, which is still thriving to this date. Dragonflies are known natural predators of mosquitoes and other insects, thus a commonly used integrated pest management (“IPM”) measure has proven to be e ective in the long term. Currently, there are a total of 14 species of flying adults of dragonflies and damselflies throughout the day. These dragonflies feed on mosquitoes and other pests, serving as a natural control mechanism with a hunting e ciency rate of up to 95%. Natural controls such as dragonflies, birds, bats and minnows enhance the biodiversity in a given site, in line with ESG principles. They also avoid the introduction of chemical or bacterial agents into the site’s existing ecosystem, seen in conventional controls such as pest fogging and mosquito dunks utilising targeted bacteria such as Bacillus thuringiensis israelensis to control larvae populations.
