absence of insecticide resistance in anopheles gambiae s.l. (diptera: culicidae) after four decades of residual house spraying in gokwe district, zimbabwe.field tests showed that anopheles gambiae s.l. from 4 villages in gokwe district, midlands province, zimbabwe, were susceptible to 4% ddt, 0.025% deltamethrin, 0.025% alpha-cypermethrin, and 0.1% lambdacyhalothrin. in the laboratory, f1 progeny of field-caught females that were identified as anopheles arabiensis patton were completely susceptible to deltamethrin, alpha-cypermethrin, lambdacyhathrin, and ddt. the use of insecticides in gokwe district has not yet induced detectable resistance in a ...200010730502
pyrethroid resistance in the major malaria vector anopheles arabiensis from gwave, a malaria-endemic area in zimbabwe.insecticide resistance can present a major obstacle to malaria control programmes. following the recent detection of ddt resistance in anopheles arabiensis in gokwe, zimbabwe, the underlying resistance mechanisms in this population were studied.200819038063
do mosquito coils and killer sticks work against anopheles gambiae sensu lato mosquitoes in zimbabwe?tests against anopheles gambiae s. 1. mosquitoes (malaria transmitting mosquitoes) were carried out in chegutu, chiredzi and kamhororo (gokwe). these tests were done in relatively closed rural huts and experimental huts. the tests demonstrated that a one hour exposure to smoke from the burning of insecticidal coils contain 0.3 pc pyrethrin, achieve 100 pc knockdown of mosquitoes. mosquito killer sticks gave 85 pc knockdowns with 30 pc recoveries and less than 10 pc recoveries for the coils. with ...19947954723
