    Abstract:
    Field-collected female Psorophora howardii (Coquillett), Psorophora ciliate (F.), and Psorophora ferox (Humboltd) mosquitoes were tested in laboratory conditions to measure body size, blood engorgement duration, bloodmeal size, fecundity, and egg morphology. Mean bloodmeal size was significantly different among the three species of mosquitoes, whereas there was no difference in blood engorgement duration. Mean body weights and wing lengths of Ps. howardii and Ps. ciliata were significantly greater than Ps.ferox. Seven days after bloodmeals, oviposition rates for Ps. howardii, Ps. ciliata, and Ps.ferox were 18.8, 56.2, and 0%, respectively. The mean number of total eggs produced per female for the three species was 59, 81, and 73, respectively. Mean egg lengths of Ps. howardii and Ps. ciliata were significantly greater than Ps.ferox, and egg diameters for each of the three species were significantly different from one another. Length per diameter ratios of Ps. howardii and Ps. ciliata were significantly smaller than Ps. ferox. Bloodmeal size was positively related to body weight, but not related to blood engorgement duration, and the total egg number was positively related to bloodmeal size.
