| We analyzed the reproductive status, ovarian development, daily survival rate, and length of the gonotrophic cycle in females of Anopheles ( Kerteszia ) cruzii Dyar & Knab, to determine how these factors influence the risk of malaria transmission in the coastal region of the state of Paraná, southern Brazil. In the Palmito State Forest, Paranaguá, females were captured at dawn and dusk by aspiration, bimonthly from December 2006 through March 2007. A total of 2,268 females were captured, of which 454 were dissected. Of these, 48% were parous, 50% not reproductive, 73% in Christopher and Mer stages I and II, 23% in stages III to V, 55% nulliparous, 14% uniparous, and 11% had blood in their midgut. Daily survival was 0.24 ± 0.03 overall, 0.51 ± 0.04... |
