Role of bacteria in mediating the oviposition responses of Aedes albopictus (Diptera: Culicidae).

Laboratory evaluation of 21 insect repellents as larvicides and as oviposition deterrents of Aedes albopictus (Diptera: Culicidae).

Twenty-one commercial insect repellent products, including 12 botanical, 6 DEET-based, and 3 synthetic organics, were evaluated as larvicides and as oviposition deterrents of Aedes albopictus. Ten of the 12 botanical products at 0.1% concentration provided 57-100% mortality of laboratory-reared 4th-stage Ae. albopictus larvae at 24 h after treatment. Five of the 6 DEET-based products and 3 synt...

VERTICAL OVIPOSITION PREFERENCES OF THE ASIAN TIGER MOSQUITO, AEDES ALBOPICTUS (DIPTERA: CULICIDAE), IN TEMPERATE NORTH AMERICA by ERIC JASON WILLIGES

Laboratory and field evaluations of oviposition responses of Aedes albopictus and Aedes triseriatus (Diptera: Culicidae) to oak leaf infusions.

Organic infusions created by fermenting white oak (Quercus alba L.) leaves in water were evaluated as sources of attractant odorants and contact oviposition stimulants for gravid Aedes albopictus (Skuse) and Aedes triseriatus (Say). Infusions were bioassayed in the laboratory by giving single females a choice of ovipositing in 1 container with infusion and 7 containers with water. Ae. albopictu...

Wolbachia-induced cytoplasmic incompatibility in single- and superinfected Aedes albopictus (Diptera: Culicidae).

Maternally inherited bacteria of the genus Volbachia can cause cytoplasmic incompatibility resulting in the developmental arrest of early embryos. Previous studies have shown that both single- and superinfections of Wolbachia naturally occur in populations of Aedes albopictus (Skuse). Here, we report crossing experiments using three infection types occurring in Ae. albopictus: uninfected, singl...

Boric acid ovicidal trap for the management of Aedes species.

BACKGROUND & OBJECTIVES The use of low concentrations of boric acid as a potential and effective control agent for the eggs and immature stages of Aedes aegypti L. and Aedes albopictus Skuse (Diptera: Culicidae) is found to be safe and effective as compared to synthetic chemical insecticides. The study aims to determine the ovicidal concentration of boric acid, its effective concentration for o...
