Influence of host anemia on blood-feeding rate and egg production of Aedes aegypti (L.) (Diptera : Culicidae)

By 

Abstract

Graduation date: 1992I tested a theoretical model proposing that anemia\ud favors transmission of blood-borne parasites to vectors\ud by accelerating the blood-feeding rate. Using Aedes\ud aegypti, the yellow fever mosquito, initially, I was not\ud able to confirm this phenomenon either in an artificial\ud or a live system; anemia did not correlate with blood-feeding\ud rate, time or volume. I then analyzed the\ud feeding rate over different time intervals to examine the\ud possibility that inconsistent feeding rates masked the\ud expected results; a comparison of the blood-feeding rate\ud at one particular time period supports the theory.\ud I then continued investigating the influence of\ud anemia on egg production of mosquitoes and found that\ud anemia has negative influence on vector's fecundity. I\ud conclude that although anemia has opposite influences on\ud mosquitoes in blood-feeding rate and egg production, they\ud can get, at least under certain conditions, benefit from\ud blood-feeding on anemic hosts
