          Abstract

          Relatos da resistência de Aedes aegypti (L.) ao temefós em vários estados brasileiros, justificou esta pesquisa que teve por objetivo verificar e caracterizar a resistência ao temefós de populações de A. aegypti da Paraíba. A resistência ao temefós foi avaliada e caracterizada a partir da dose diagnóstica de 0,012 mg/l, e de curvas de concentração-mortalidade. Os dados de mortalidade nas concentrações múltiplas foram submetidos à análise de Probit, sendo as razões de resistências calculadas a partir das CL50s das populações resistentes e da CL50 da população suscetível de laboratório. Todas as populações de A. aegypti mostraram-se resistentes ao temefós. A população do Sítio Piabas com RR = 4,0 apresentou baixa resistência, as populações de Campina Grande com RR = 6,0, Lagoa do Mato com RR = 9,3 e Capim de Cheiro com RR = 9,0 apresentaram moderada resistência, e Boqueirão com RR = 11,0, Brejo dos Santos com RR = 16,6 e Itaporanga com RR = 15,6 mostraram média resistência ao temefós. Os resultados confirmam a necessidade contínua de um programa de monitoramento e manejo da resistência de A. aegypti na Paraíba.

          Rumors of Aedes aegypti (L.) resistance to temephos in diferent Brazilian states justified this research, whose objective was to verify and characterize the resistance to temephos in A. aegypti populations from Paraíba State. The temephos resistance was evaluated and characterized through a diagnostic dose of 0.012 mg/l and concentration-mortality curves. The mortality data of multiple concentrations were submitted to Probit analysis, and the resistance ratios (RR) were figured out from the CL50s of the survived population and CL50 a laboratory susceptible population. All the A. aegypti populations showed resistance to temephos. The Sítio Piabas population with RR = 4.0, showed lower resistance, the Campina Grande with RR = 6.0, Lagoa do Mato with RR = 9.3 and Capim de Cheiro with RR = 9.0, showed a moderate resistance, and Boqueirão with RR = 11.0, Brejo dos Santos with RR = 16.6 and Itaporanga with RR= 15.6, showed intermediate levels of resistance to temephos. These results confirm the need of a continuous monitoring and managing program of A. aegypti resistance in Paraíba State.
