Abstract

Data on insecticide resistance in mosquitoes from Mississippi are reported. Mosquitoes were collected from June through October 2017 from 28 cities in Mississippi and included wild-caught Culex quinquefasciatus Say obtained as egg rafts (reared to adults), and Aedes albopictus (Skuse) collected as larvae (reared to adults). The Centers for Disease Control and Prevention (CDC) bottle bioassay protocol was utilized. Thirty-six populations of Cx. quinquefasciatus were tested for malathion resistance from 24 cities; 22 of them (61.1%) met the World Health Organization criteria as resistant, and the remaining 14 (38.9%) were classified suspected resistant. Forty-one populations of Cx. quinquefasciatus were also tested from 24 cities for resistance to permethrin, and of these, 18 populations (43.9%) were susceptible, 13 (31.7%) were resistant, and 10 (24.4%) were suspected resistance. Eighteen populations of Ae. albopictus were collected from 10 cities in Mississippi for resistance testing to malathion; 5 populations were susceptible (27.8%), 5 were resistant (27.8%), and 8 (44.4%) suspected resistant. Sixteen populations of Ae. albopictus were tested from 10 cities for resistance to permethrin and none were resistant.
