Ovipostional behavior, larval survivorship, and temporal biting cycle of Aedes triseriatus in the flood plains of Fortbend [i.e. Fort Bend] Co. Texas
MetadataShow full item record
Aedes triseriatus(Say), the common treehole mosquito, utilized all tree heights between ground level and 3.7 meters for oviposition, from June-August, 1985. Percentage of eggs decreased with increasing oviposition heights, however, greater preferences were found for ground level to 1.2 meters. More eggs were deposited at all heights in June than in July and August, although mean percentage of eggs for June, July and August did not differ. Heights exceeding 1.2 meters yielded fewer eggs for the summer and more eggs were deposited between July and August. Larval survivorship depended upon treehole fluid concentration and density of larvae/concentration. Survivorship was greater at low density and denser detritus concentration. Greater number of male adults emerged from surviving larval populations, however, the ratio of male/female was not dependent on the concentration or larval density. Biting occurred during the day with early morning and late afternoon peaks and continued into a crepuscular peak.
