Cannibalism in mosquito larvae during microbial larvicide potency tests

Pyriproxyfen as a Mosquito Larvicide

Pyriproxyfen is an insect growth regulator that affects the physiology of morphogenesis, reproduction and embryogenesis of insects. It exhibits a high level of activity against mosquito larvae inhibiting adult emergence at very low dose rates. It has low mammalian toxicity and environmental impact. This paper reviews pyriproxyfen efficacy against nuisance mosquitoes and vectors of dengue and ma...

BVA 2 mosquito larvicide--a new surface oil larvicide for mosquito control.

BVA 2 mosquito larvicide was evaluated in laboratory pan tests against 3rd-instar Aedes taeniorhynchus (Wied.), Culex quinquefasciatus Say, and Culex nigripalpus Theobald larvae. BVA 2 was as effective as the standard, GB-1111, at 14 liters/ha (> 99.1% vs. 99.8%). In small field plot tests BVA 2 mosquito larvicide applied at 28 liters/ha was as effective as GB-1111 (99.0% vs. 99.8%) 24 h posttr...

Predatory cannibalism in Drosophila melanogaster larvae.

Hunting live prey is risky and thought to require specialized adaptations. Therefore, observations of predatory cannibalism in otherwise non-carnivorous animals raise questions about its function, adaptive significance and evolutionary potential. Here we document predatory cannibalism on larger conspecifics in Drosophila melanogaster larvae and address its evolutionary significance. We found th...

Osmotic regulation in mosquito larvae.

Aedes Mosquito Larvae CoLLeCtion

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...
