A researcher in Australia has actually created an insecticide-free method to manage an especially annoying types of mosquito.
The method includes 2 things: releasing an extremely low-tech mosquito trap called a GAT and learning more about your next-door neighbors.
GAT means Gravid Aedes Trap. Aedes is brief for Aedes albopictus, recognized informally as the Asian tiger mosquito, which bites strongly night and day.
The trap does not look especially remarkable– it’s generally 3 plastic containers stacked together. The leading and bottom containers are black. The mosquitoes fly into the trap through a hole in in the leading container, however they appear to have a tough time flying back out through the hole. To make matters even worse (for the mosquito) you can hang a piece of sticky paper inside the leading container to capture a stubborn insect that occurs to land there.
The bottom container includes water with some decaying turf drifting in it. Aedes mosquitoes usually lay their eggs in stagnant water. The middle container has a net to trap any mosquitoes that hatch in the water.
It’s an easy setup, however the researcher who developed the GAT, Scott Ritchie of the Australian Institute of Tropical Health and Medication at James Cook University, states there are numerous factors it works.
” A lot of mosquitoes are innately brought in to black,” Ritchie states, so that’s exactly what entices them in.
Female mosquitoes are the ones that bite individuals, and when they’re packed with blood, they aspire to lay eggs.
” So we have actually got the blackness that brings them to the trap, and after that we have actually got the stagnant water in fact inside the trap where they cannot get away,” Ritchie states. “If you trap out enough of the egg-laying mosquitoes, then there aren’t going to be eggs in the wild, so the population will crash.”
However the traps alone aren’t enough to obtain rid of the pesky mosquito. Ritchie states it is essential for property owners to remove any swimming pools of standing water. Deserted tires, for instance, are infamous for gathering water after it rains, however even an inverted bottle cap can hold sufficient water for an Aedes mosquito to lay her eggs.
There’s another crucial to managing the mosquito population in a neighborhood: Everyone needs to pitch in. If your next-door neighbors do not utilize the traps and eliminate standing water, then mosquitoes are most likely to grow and will not mind flying over to your backyard for a treat.
However there is some great news. “These mosquitoes do not fly really far,” states Dina Fonseca, a mosquito professional at Rutgers University. “So generally if you have the majority of your next-door neighbors using this method and knowledgeable about exactly what they have to do to manage this mosquito, you remain in good condition.”
Then she includes with a smile, “It does need talking with the next-door neighbors.”
There’s currently some clinical proof that the traps can be efficient. Fonseca is dealing with numerous neighborhoods around Washington, D.C., to see if the control program works. Anecdotally, citizens inform her the variety of mosquito bites has actually decreased in locations where individuals are utilizing the traps and getting rid of standing water. The clinical evidence is still a methods off.
