article about mosquito coil resistance test procedure

Anopheles coluzzii larval habitat and insecticide - article about mosquito coil resistance test procedure ,May 20, 2016·A total of 1397 females, including 784 specimens from Manoka and 613 from Youpwe, were used for resistance testing The two mosquito populations displayed resistance to DDT, permethrin and deltamethrin, with variable mortality rates from 1 % to 90 % The knock-down times were also significantly increased (at least 28 fold)Mosquito Control | Pesticide Research InstituteThe effectiveness of most other products marketed to repel mosquitoes differs greatly Burning citronella candles or mosquito coils containing allethrin are for outdoor use only and work best when there is little air movement Plant oils such as pine, spearmint, geranium and neem will help deter mosquitoes
