The manual aspirators are integral to conduct mosquito research. Collections made using classic aspirators which has a glass or polycorbonate collection tubing and a silicone collecting tube to suck the air. It is the most simple, easy and quicker way to collect mosquitoes. However, the drawback with the classic aspirators is the manual sucking which is really tiresome and entry of unwanted particles to human mouth while making mosquito collections in dusty or unhigenic surfaces. It's is the most economical way of working with mosquitoes.
Filter based classic aspirators
Recently, as a substitute to mitigate the negative effects of having a wire mesh between the silicon tubing and the glass collection tube, a HEPA or similar purpose material have been introduced. These filters have taken care of the negative aspects of the classical aspirators while protecting the costing factor.
Improved mosquito aspirators with collection chamber installed with dust/allergin filters
One of the disadvantages of the classic aspirators is the damages to the mosquitoes. The collected mosquitoes need to sucked frequently to keep them in the collection tube. This will exert unwanted pressure on the mosquitoes. When collection of multiple insects made they started becoming piling on one another fighting to be free and space. A new improved model has been introduced recently to address this issue. These aspirators has three parts: collection tube (acrylic or PP), collection chamber (polycorbonate) and sucking tube (silicone or regular latex tubing). The collection chamber has 1"*2.5" (inches) inner space. Due to presence of this chamber mosquitoes find it bit difficult to escape when pressure not available to hold then back in the place.
Mechanical aspirator Mechanical aspirators are great way to work in the field as well as in laboratories for a longer periods of collections. Use of these aspirators is less tiring, convenient and quick. The battery operated mechanical aspirators suck insects due to reverse moment of the fan. The mosquitoes are released into mosquito containers safe transporting insects into the laboratory. The aspirator comes with one collection tube and a chamber to collect sucked insects. The replacement batteries need to be bought as and when exhausts
