Abstract

The blood-engorgement kinetics of Anopheles aquasalis, Aedes aegypti, Haemagogus janthinomys, and Culex quinquefasciatus were determined under laboratory conditions using females collected from three field sites in Trinidad. Most An. aquasalis, Ae. aegypti, and Hg. janthinomys completed probing within 70 s but Cx. quinquefasciatus averaged >180 s. Anopheles aquasalis (67.0 s) had the shortest gut filling time while Cx. quinquefasciatus had the longest gut filling time (222.8 s). Aedes aegypti and Hg. janthinomys had similar gut filling durations, 87.7 s and 90.4 s, respectively. More than 70% of An. aquasalis, Ae. aegypti. Cx. quinquefasciatus, and Hg. janthinomys showed prediuresis. Anopheles aquasalis exhibited the shortest mean duration of prediuresis (77.3 s) and Cx. quinquefasciatus the longest (526.9 s). Most individual mosquitoes spent less time filling their guts than in prediuresis. Overall, An. aquasalis exhibited the shortest total feeding time (135.7 s) and Cx. quinquefasciatus the longest (661.9 s). Individual An. aquasalis mosquitoes showed a high degree of variability in their ability to agglutinate human erythrocytes immediately upon blood engorgement, with individuals agglutinating <25% of the ingested erythrocytes and others ≥90%. Among Ae. aegypti and Cx. quinquefasciatus, the proportion showing agglutination varied from 0% (67% and 69% respectively) to <50%. The parity of the field collected mosquito vectors had no significant effect on probing, duration of blood-feeding, duration of prediuresis, or erythrocyte agglutination. The inter- and intra-specific variation in blood-feeding and erythrocyte processing observed for the four vector species collected from the field in Trinidad are described in terms of vector competence and evolution of these behaviors.
