Mosquitoes lay eggs on a piece of paper floating in the water. At regular intervals the water is run through a filter and the paper replaced to remove any deposited eggs and larva. The water is then re-used, because mosquitoes release an 'oviposition' pheromone when they lay eggs, and other mosquitoes are attracted to water which contains this ...
The eggs then fall through the mesh into the water, where the larvae hatch and develop into pupas. When the adult mosquitoes emerge, they are trapped beneath the mesh and are unable to escape from the ovitrap. [1] Ovitraps mimic the preferred breeding site for container breeding mosquitoes, including Aedes albopictus and Aedes aegypti. [2]
An Ovitrap, a tool for the collection of eggs from tiger mosquitoes: In this case, an ovitrap type used for the monitoring of the Asian tiger mosquito Aedes albopictus in the Swiss canton of Ticino. The presence of the mosquitoes is detected through the eggs they lay on the wooden paddle or from larvae that hatch from these eggs in the laboratory.
Aedes koreicus is known to be a container breeding mosquito. [3] They lay eggs in all types of artificial containers and natural holes that are found in plants and rocks in urban, peri urban, and natural environments. [3] Aedes koreicus lay approximately 100 eggs at a time, and can lay eggs up to three times per life cycle.
This ensures as many eggs as possible will survive if the breeding sites are damaged or dried up. Because these mosquitoes jump from breeding site to breeding site, the chances that they will find an ovitrap are extremely high, almost certain if enough ovitraps are placed around natural breeding sites.
This is a naturally occurring bacteria that kills the mosquito larvae. It only affects mosquitoes and doesn’t harm beneficial insects such as butterflies and bees or fish, frogs, people and pets.
Augmentation involves the supplemental release of natural enemies that occur in a particular area, boosting the naturally occurring populations there. In inoculative release, small numbers of the control agents are released at intervals to allow them to reproduce, in the hope of setting up longer-term control and thus keeping the pest down to a ...
