We would like to study the availability of apply old or establishing new vector control technique during mosquitoes swarm, but I am not sure whether to try old one or working on designing new tool.
Dear colleague,
Experience with several kinds of vectors tells us that in considering their control it is needed to do it in context. Any tool or technique per se (by itself) is not going to give you the result you look for. That is the reason for which the best way to address vector control is by integrated management, as the WHO recommends. It is needed a comprehensive diagnostic of situation, as well as to have a good knowledge (biology, behaviour, etc) of the vector you are pointing out. For sure, the main issue is not about if the best tecnique is old or very new. You mention mosquitoes in general. I think that if you are more specific regarding what type of mosquito you need to control and why, you will get better help. I suggest you to review WHO materials regarding vector control, keeping in mind that research is made for living better. I hope to have helped a little.
I agree with you Mayira Sojo-Milano that there is no single effective tool but many of them should be applied
Mayira Sojo-Milano, i agree with your response very much.
Additionlly before you choose a tool for use against a known vector species , its recommended to do insectcide resistance tests against the insectcide used in that tool. Insectcide resistance as been the most worst part in toool selection. Hoping I have added value
Aedes aegypti and Ae. albopictus are the most evasive vectors that transmit dengue, chikungunya, Zika and more than 30 other viruses. Their larvae live in artificial containers that near human residential area. Most of the containers are cryptic that cannot be reached by conventional pesticide sprays. Some of the technologies that can target the cryptic habitat are being evaluated such as autodissemination, release male mosquitoes treated with insect growth regulators. Other technology such as releasing GM mosquito males, Wolbachia infected male release are also showing promising result. In the end, as Mayira mentioned, there is no single technology works as silver bullet. IPM is the way to go!
Public awareness has to be created about the measures to be taken to prevent their multiplication, for example, the water stagnation near the residences, storage of water in open containers etc. must be avoided. The IPM strategy needs to be applied, WHO recommendations may be followed.
For Aedes control source reduction is the best bet, especially Aedes aegypti. However, Aedes albopictus is a tricky species as they also breed in inaccessible habitats like tree holes. In this case you have to couple anti-adult strategies with source reduction.
May be a community based control approch i.e. reducing the ovipositing sites of Aedes by the residents themselves can reduce the Aedes population.
Combining SIT ITT could work though much needs to be done ( optimized rearing) before reaching this point..
