The 1st confirmed record of Culex coronator for Louisiana was made at Fort Polk, LA, from carbon dioxide-baited light trap and gravid trap collections performed from April to October 2004. In addition to the new record, 17 mosquito species in 5 genera (Aedes, Anopheles, Coquillettidia, Culex, and Psorophora) were collected. Collection-site and species distribution data are included.

Mosquitoes in the Culex pipiens complex (Diptera: Culicidae), especially Cx. pipiens and Culex quinquefasciatus, have successfully exploited the rapid growth of the human population and globalization to their advantage by successfully utilizing man-made habitats, particularly for oviposition. Culex spp. lay over 100 eggs together in a raft. Each egg in the raft produces an apical droplet contai...

Insect-specific flaviviruses (ISFVs) commonly infect vectors of mosquito-borne arboviruses. To investigate whether infection with an ISFV might affect mosquito flight behavior, we quantified flight behavior in Culex pipiens L. naturally infected with Culex flavivirus (CxFV). We observed a significant reduction in the scotophase (dark hours) flight activity of CxFV-positive mosquitoes relative t...

three media formulated from molasses and cornsteep liquor and another media based on the basal medium formulation of ips-82 were assessed for the growth and production of insecticidal properties of b. thuringiensis h-14 .• bacterial powders prepared from the broth cultures were assayed against the larvae of culex pipiens and anopheles stephensi. a standard powder of ips-82 was included in the a...

in order to determine the control of breeding sources of culex larvae in sewage wells by the larvicide abate, some studies were performed in the summer and autumn of 1972. in general, it was noticed in these studies that:1. the wells chosen as a control (5 wells) were active throughout the study periods and adult mosquitoes were captured plentifully. 2 in 4 sewage wells which were controlled by...
