Cynoff 25ULV (cypermethrin 25 g/l) and Solfac UL015 (cyfluthrin 1.5% w/v) were evaluated against the sentinel sugar-fed adults and 4th-instar larvae of Aedes aegypti in a housing estate endemic of dengue in Malaysia. The impact of both pyrethroids on field populations of Aedes albopictus and Aedes aegypti larvae was monitored weekly using bottle containers. Both Cynoff 25ULV and Solfac UL015 sh...

BACKGROUND & OBJECTIVES The Colombo City in Sri Lanka is experiencing tremendous development and construction of multiple storey buildings and high rise apartments. The change in housing types and microhabitats might have altered the flight and breeding behaviour of Aedes mosquito population. This study was carried out to determine the vertical dispersal and abundance of Aedes mosquitoes in mul...

Methods employed by Australian quarantine officers to control Aedes mosquitoes in containers were tested against all stages of Aedes aegypti. Saltwater emersion killed all larvae but not pupae or eggs that were briefly exposed. Swimming pool chlorine, methyl bromide fumigation, and permethrin (2% active ingredient) spray provided 100% mortality of eggs, larvae, and pupae. Aerosol sprays incorpo...

Adult female Aedes aegypti that were reared on a suboptimal diet as larvae were less likely to engage in host-seeking behavior than were adults derived from larvae reared on an optimal diet. A postemergence carbohydrate diet of either 1 or 10% sucrose solution did not affect this response. When the progeny of field-collected Aedes vexans were reared in the laboratory, the adults were significan...

The lady beetle, Curinus coeruleus (Mulsant), a biological control agent of the coconut mealybug, Nipaecoccus nipae (Maskell) and the psyllid, Heteropsylla cubana Crawford, was examined for its ability to consume Aedes albopictus (Skuse) eggs in the laboratory. Most C. coeruleus larvae in this test preyed on A. albopictus eggs (75% for the 2 and 3 instar and 71% for the 4 instar). The 2 and 3 i...

An investigation of habitat preference for larval breeding sites by Aedes (Diptera: Culicidae) mosquitoes which occur around human dwellings in Ishigakijima and Taketomi-jima Islands revealed that Ae. albopictus Skuse 1894 preferred pools in tires and boats and was distributed widely from the coast, inland. Although Ae. riversi Bohart & Ingram, 1946 and Ae. flavopictus miyarai (Tanaka et al, 19...

Aedes albopictus was found in M. Muzquiz, Coahuila, Mexico, in the summer of 1993. Aedes albopictus larvae were collected in tires and bottles at low density. Aedes aegypti, Toxorhynchites theobaldi, Culex quinquefasciatus, and Culiseta incidens were collected in the same containers.

Different standing water bodies act as breeding grounds of mosquitoes, thus responsible for the spread of diseases. A survey was conducted to study the population dynamics of mosquito larvae in three village ponds of Ludhiana district (Punjab), India. For this purpose water samples were collected at monthly intervals from July 2011 to June 2012 and larval density (LD/L) and larval density index...

Laboratory-bred females of Culex quinquefasciatus, Aedes aegypti and Aedes albopictus from the insectarium, Unit of Medical Entomology, Institute for Medical Research were used in the experiment. The late third stage of the F0 larvae which survived the high selection pressure of malathion, permethrin and temephos were reared and colonies were established from adults that emerged. Cx. quinquefas...

OBJECTIVE To evaluate the efficacy of fish as predators of the Aedes aegypti larvae in laboratory conditions. METHODS The male and female of five different fish were included in the experiment. The tests to measure their consumption ability lasted five weeks for each species. Each trial involved four test tanks and four control tanks. Two control tanks contained just one fish, and the other t...
