According to Dan Strickman, a senior program officer in vector control at the Bill and Melinda Gates Foundation, that is what happened with resmethrin and allethrin
, two pyrethroids used in mosquito control.
All 3 coils (FISH M (0.005% metofluthrin)) 86%, Shieldtox (0.15% d-trans allethrin
) 74%, and Tesco Value (0.3% allethrin
) 72% showed high knockdown efficacy.
If you're in an open-air stand, nothing works better than a ThermaCell, which uses butane heat to vaporize an insect repellant called allethrin
, which, according to the company, is a copy of a repellant that occurs naturally in chrysanthemum flowers.
The type segment is further classified in to bifenthrin, deltamethrin, permethrin, cypermethrin, cyfluthrin, lambda-cyhalothrin and other pyrethroids (fenvalerate, resmethrin, tetramethrin, allethrin
, phenothrin, barthrin, dimethrin, and bioresmethrin).
The butane heats a mat to release the repellent allethrin
, with each mat holding enough repellent to last four hours.
Collecting cloths were placed beneath vegetation, and then all vegetation was saturated with insecticides (Pre- Strike[TM]--active ingredients: piperonyl butoxide 1.0%, tetramethrin 0.2%, etofenprox 0.1%; Raid House & Garden[TM]--active ingredients: d-cis trans allethrin
0.239%, 3-phenoxybenzyl d- cis and trans 2,2-dimethyl-3-(2-methylpropenyl) cyclopropanecarboxylate 0.096%).
dirus subjected to dl, d-T80 allethrin
(0.27% - 0.50% w/w) mosquito coils under a 25 m3 room experimental setup were also fairly low, ranging between 20.8 -28.3 min and 8 min respectively (Katsuda et al., 2008).
The potential of induction of mutagenicity of mosquito coil in humans is therefore a major concern, because it could account for infertility in males, as was also demonstrated by Madhubabu & Yenugu (2012) in a study of the effect of continuous inhalation of allethrin
based mosquito smoke in the male reproductive tract of rats.
, bioallethrin, tetramethrin, phenothrin, resmethrin, bioresmethrin, kadethrin, permethrin, cypermethrin, fenvalerate, deltamethrin and flumethrin.
"Type-I"-like pyrethroids include allethrin
, bifenthrin, permethrin, phenothrin, resmethrin, tefluthrin and tetramethrin.
