Gf. Omeara et al., COLONIZATION OF ROCK HOLES BY AEDES-ALBOPICTUS IN THE SOUTHEASTERN UNITED-STATES, Journal of the American Mosquito Control Association, 13(3), 1997, pp. 270-274
Aedes albopictus was collected from water-holding rock holes along 3 s
treams in Georgia and 1 in South Carolina. To compare the occurrence o
f Ae. albopictus and Aedes atropalpus, rock holes were sampled for imm
ature Aedes at 2 sites where there were numerous rock holes harboring
mosquitoes. At 1 of these sites, tree holes and various types of artif
icial containers were also sampled for immature Aedes. At both sites,
immature Ae. albopictus occurred in rock holes much less frequently th
an the rock-pool specialist, Aedes atropalpus. Moreover, the distribut
ion of Ae. albopictus was limited to rock holes in less flood prone lo
cations, whereas Ae. atropalpus was often a common mosquito even in ro
ck holes that were among the most susceptible to flooding by rising st
ream levels. By contrast, Ae. albopictus was frequently found in the s
amples from tree holes and artificial containers. Thus, it appears tha
t riverine rock holes that are flooded frequently may be, at best, mar
ginal habitats for Ae. albopictus.
