Is lethal ovitrap an effective method to control mosquitoes?
I am going to use lethal ovitrap to control mosquito population. What the advantage and disadvantage of this method to control mosquito. What is the most advance lethal ovitrap right now and how does it work?
Most recent answer
Ovitraps are designed to facilitate insect collection as the design and color of the trap would determine its efficiency. For mosquito control, emphasis are on the elimination of the vector which is motile hence the need for numerous ovitraps, its time consuming too and not commensurately rewarding. In a scenario of mass control, I would advise integrating insect growth inhibitors with your ovitraps.

Lethal ovitraps are not a control method. The number of eggs is not a limiting factor in the mosquito population dynamic. From the breeding places of your landscape you will obtain the same number of female mosquitoes with or without lethal ovitraps. Only a big number of ovitraps able to compete in actractivity with the natural breeding places could reduce the mosquito number ... but is only a theoretical hypothesis.

Although few papers are available focusing on aedes but I also think you have to set a lot of traps for significant outcome (that can be done by other traps). Wikipedia can help:https://en.wikipedia.org/wiki/Lethal_ovitrap

The idea behind the use of ovitraps as mosquito population control is that mosquitos will lay their eggs in a container which will be removed by someone (researchers, government, etc), thus diminishing the number of eggs that will hatch and that will eventually become adults.

You are inviting female mosquito to lay eggs in a hostile environment. I know she is smart than you think. She is highly selective . Lethal ovitraps are a gimmick, not effective in control methodology.
Try and tell us how many eggs you destroy in a week per trap...Good luck.

Thank you Mr. Pantaleoni, Mr. Al-Amin, Mr, Paploski, and Mr. Aslamkhan for your answer.
I see. So the main problem using lethal ovitrap to reduce mosquito population is to compete with mosquito natural breeding place.
How about the use of chemical attractant? Does it help?

yes Its a tool to reduce mosquito burden by addition of new breeding site which lure mosquito to lay eggs and reduce the burden of breeding in other containers in addition to this the laid eggs do not become adults therefore, to reduce the densities of Aedes they are definitely useful

The new BG-GAT traps from Biogents were used to control Aedes populations. However, large numbers of traps were used and you should remove natural breeding sites, that might compete with the BG-GAT.
Go with an insect growth regulator in the water of your Lethal ovitrap. Periproxyfen would work as it has properties that sterilze ovidepositing females as well. But any non-repellent chemical should work (fipronil comes to mind).
Lethal Ovitraps and BR-GAT autocidal are not the silver bullet, but can significantly impact Aedes populations.

Lethal ovitrap is not a magic bullet. But these can be used as a part of integrated vector management together with other environmental control programmes such as removal of all man made containers etc. Thereby placement of a few lethal ovitraps in small premises has shown a very clear reduction of mosquito (Aedes)
populations. IGR, Novaluron (Rimon) added to the ovitrap is effective with at least 6 weeks residual effect. Trying to introduce this in Sri Lanka.

Have to use high number of lethal ovitraps to control the vector population. Do not use as main method to control but as an addition to common control strategies such as 'search and destroy' breeding sites, chemical interventions (fogging, ULV) and larviciding.
I think you should consider other control methods.The use of ovitraps might not be beneficial as a control method.
