From the day, dinosaurs walked the Earth and till now that human is the dominant species, we have always been bothered by mosquitoes. There is a secret weapon to eliminate them, the bug spray, and it has worked until now, which is rather annoying.
One thing that all haters of this vampiric insect, realize is that they are hard to kill. Well, there is fly swatter, but sprays are the best. There is a wee bit of a problem too because bug spray is not always effective on them. Most unfortunate, when one wishes that most of them will just die with insecticide.
The real problem is how well they adapt and shrug off these bug sprays like armor. Spraying more to eradicate them does not pan out either, it only causes some problems to other species. Why does nature even require such animals, to exist when they seem extraneous, with no real purpose. Other things aside, scientists are learning about two kinds of mosquitoes. To spice things up, these two are major disease carriers that are Anopheles gambiae and Anopheles coluzzii which makes them threats to human health.
Days of these intolerable insects are numbered when the research done on these two will find out their secrets. As to how they become more insecticide-resistant, it is because of their legs which is amazing compared to other insects. In their legs are proteins that are in high levels which is why bug spray does not always work on them. Using extra strong bug-spray will not always work, using a newspaper to crush them might be better.
Further, probing into the generation of resistance from pesticides yielded surprising insights. These annoying insects are tricky and even a bed net laced, with chemicals are rendered useless. Anyone sleeping inside it will rue going inside it because it will not work. They land on the bed netting, and that touched the insect's legs, chemical on the legs will adapt to give immunity to the bed net. Evolving this adaptation on their legs, help them cope with man poisons.
Gathering proofs and observations from the Anopheline mosquitoes, it was discovered to have SAP2 in mosquitoes that resisted insecticides well. When exposed to pyrethroids that are used to kill them when coming into contact with a bed net, it was nothing to pesky mosquitoes. One way to kill them is to lower their resistance to SAP2, an insecticide that is attacked by increase SAP2 bug spray is more effective.
Adding increased protection to bed nets with piperonyl and pyrethroids that coats them, and kills mosquitoes on contact. Mosquitoes with less resistance will be killed by strong chemicals like cytochrome P450, but their resistance evolves too. In the meantime, these bed nets can kill disease laden-mosquitoes for now, but all these findings can help kill them later.
