<prompt> Which of the following types of mosquitoes can be controlled by removing destroying the aquatic plants by herbicides?AedesCulexMansoniaAnopheles  <response>: Ans. c Mansonia Ref. Park PSM 22nd624, 626 Control of Mansonia mosquito is easy, i.e., by removaldestruction of aquatic host plants by herbicides. Use of herbicide to destroy aquatic plants kills the Mansonia larvae as they grow on pisita plants.There are two main tribes of mosquitoes - Tribe anopheline and Tribe culicini. The tribe anopheline contains only one genus:- Anopheles. The tribe Culicini is represented in India by 15 genera, of which the important ones are:- Culex, - Aedes, and - Mansonia.Mansonia They are big, black or brown with speckling on their wings and legs. The common Indian species are:- M. annulifera, M. uniformis, M. indiana and M. longipalpis. Breed in ponds and lakes containing aquatic plants, especially the floating ones like Pistia strtiotes and water hyacinth. The eggs are laid on the undersurface of leaves. The larvae and pupae are found attached to the rootlets of these plants by their siphon tubes; they obtain their air supply from these rootlets. When about to become adults, the pupae come to water surface and fully formed adults emerge and escape. Control:-1. BiologicalThe best knowns are the Gambusia affinis, Lebister reticulates and Brabel fish.These fish were used successfully in eradicating guinea worm in parts of Kar state.2. Chemical Control:The commonly used larvicides are:a Mineral oils , b Paris green and c Synthetic insecticides.PARIS GREEN stomach poison: Copper acetoarsenite is an emerald green. Paris green kills mainly the Anopheles larvae because they are surface-feeders.SYNTHETIC INSECTICIDES: Fenthion, Clorpyrifos, and Abate are the most effective larvicides.
