“…This predator's effectiveness was further amplified when combined with reduced insecticide use. When integrated with Malathion, mosquito control reached up to 96% compared to 29% with Malathion alone [ 32 ]. Interestingly, increasing the number of Tx.…”

This review summarizes the predatory potential of Toxorhynchites mosquitoes as biological control agents for Aedes vectors. A single larva can consume hundreds of mosquito larvae during its development, with preference for larger prey and higher consumption rates at higher prey densities. Studies suggest Toxorhynchites can significantly reduce Aedes populations. Beyond direct predation, they may indirectly influence prey behavior and adult mosquito lifespan. Despite the demonstrably positive effects of Toxorhynchites species as biocontrol agents, there are acknowledged limitations that require further investigation. These limitations include potential variations in effectiveness across diverse habitats and mosquito developmental stages. Additionally, long‐term ecological sustainability and potential ramifications warrant further research. Future efforts should prioritize optimizing rearing and release strategies to enhance effectiveness. Exploring the potential for combined control methods with other biocontrol agents or traditional methods is also crucial. Finally, investigating the influence of environmental factors on predation rates can further refine and optimize the application of Toxorhynchites in mosquito control programs.

“…(malathion, temefos, and dibroma) pay dividends (Collins and Blackwell, 2000). In New Orleans, the combination of T. amboinensis and malathion reduced the population density of Aedes aegypti by 96%, while using malathion alone, only by 29% (Focks et al, 1986).…”

Predators as Control Agents of Mosquito Larvae in Micro-Reservoirs (Review)

2022

View full text Add to dashboard Cite

The article reviews predators that are able to control populations of mosquito larvae (Culicidae) in phytotelmata and their anthropogenic analogs. The spectrum of mosquito larva consumers in micro-reservoirs is listed. It includes flatworms, crustaceans, arachnids, insects, vertebrates, and carnivorous plants. The biology and practical use of the two most effective biological control agents, predatory mosquitoes Toxorhynchites and copepods, are considered in more detail. Prospects of invertebrate predators as controlling agents for the mosquito larvae in micro-reservoirs in temperate climate zones are briefly discussed. Supplementary Information The online version contains supplementary material available at 10.1134/S1995082922010138.

“…aegypti numbers showed a greater decrease following the regular release of Tx. amboinensis adult females into a region treated with ultra-low-volume (ULV) malathion pesticide than if either approach was used in isolation [139,163,164]. Further promising strategies have investigated combining Toxorhynchites with other biocontrol agents, such as the intracellular bacteria, Wolbachia [165], the entomopathogenic fungus, Metarhizium brunneum [166], an acetogenin derived from Annona mucosa seeds [167] or silver nanoparticles biosynthesized from Berberis tinctoria leaf extract [168].…”

The increasing global incidence of mosquito-borne infections is driving a need for effective control methods. Vector populations have expanded their geographical ranges, while increasing resistance to chemical insecticides and a lack of effective treatments or vaccines has meant that the development of vector control methods is essential in the fight against mosquito-transmitted diseases. This review will focus on Toxorhynchites, a non-hematophagous mosquito genus which is a natural predator of vector species and may be exploited as a biological control agent. Their effectiveness in this role has been strongly debated for many years and early trials have been marred by misinformation and incomplete descriptions. Here, we draw together current knowledge of the general biology of Toxorhynchites and discuss how this updated information will benefit their role in an integrated vector management program.
