Disruptive selection mediated by predation on aquatic immature stages has been proposed as a major force driving ecological divergence and fostering speciation between the M and S molecular forms of the African malaria mosquito, Anopheles gambiae. In the dry savannahs of West Africa where both molecular forms co-occur, the S form thrives in temporary pools filled with rainwater, whereas the M f...

In the past, Aedes atropalpus was limited to those areas of the eastern U.S. and Canada that had rivers or shorelines with large rocks containing rock pools. In the last 10 years, many new records of larval breeding in scrap tires have accumulated. We present records of larval breeding in non-rock pool containers for 54 counties; most are far from the original range. The species has not only fo...

There is growing of the effects of insecticide used controlling the vectors of human diseases. Manipulating or introducing an auto-reproducing predator into the ecosystem may provide sustained biological control of pest populations. The selection of a biological agent should be based on its self-replicating capacity, preference for the target pest population in the presence of alternate natural...

An introduced, breeding population of Aedes albopictus has been established in Harris County, Texas, and several parishes in Louisiana. The problem of its identification and separation from the indigenous Nearctic mosquito fauna is addressed. Using the keys of Darsie and Ward (1981), the author offers suggested inserts which will accomplish the identification of adult females and larvae in the ...

BACKGROUND & OBJECTIVES Rajasthan is one of the dengue endemic states of India. Very few studies have been published on entomological aspects of dengue in this state. Owing to water scarcity, inhabitants in desert areas overstore domestic water which leads to the persistence of dengue vectors within the domestic premises. Area specific knowledge on breeding, key containers and seasonal rhythms ...

INTRODUCTION Many efforts have been made to ease the burden of malaria through vector control, among whichis the development of odor-baited traps and evaluation of efficient attractants that could replace host odor. However, most traps and evaluated attractants are expensive, which poor communities cannot afford. This study was conductedwith the aim to devise asimple and affordable odor-baited ...

Stormwater catch basins in urban areas provide important larval habitat for Culex mosquitoes. In this study we quantified adult Culex emergence using a newly designed emergence trap deployed in catch basins in suburban Chicago, IL. Traps were deployed from late June to mid-October, 2009-10, in 19 catch basins for a total of 461 trap-days. Based on laboratory trials, the percentage of adults eme...

Simple and economic methods were developed for control programs to demonstrate the movement of mosquitoes from a breeding source to residential areas. Using mark-release-recapture methods and examples, mean, median and maximum distances traveled were estimated or observed and compared for 11 species produced in a wastewater treatment facility near Lakeland, FL. The applicability of these method...

On August 2, 1985, numerous adults and larvae of an unknown species of Aedes were collected from several widely separated tire dumps, in and around the city of Houston, Texas. Specimens sent to Dr. Y.-M. Huang at the U. S. National Museum, were identified as Aedes albopictru (Skuse), a container-breeding species, indigenous to the Oriental and Australian regions. Aedes albopictu.r has been coll...
