Dengue and dengue hemorrhagic fever are mosquito-borne viral diseases that coincide with the distribution of Aedes aegypti (L.), the primary vector in the tropical and semitropical world. With no available vaccine, controlling the dengue vector is essential to prevent epidemics. The effects of the insect growth regulator pyriproxyfen on Ae. aegypti...

A Culex quinquefasciatus Say colony was selected for 45 generations at LC70-90 levels using Natular XRG, a granular formulation of 2.5% spinosad for induction of spinosad resistance. Resistance to spinosad was noticed in early generations (F1-F9). Resistance levels increased gradually from generations F11-F35, and elevated significantly from genera...

The effectiveness of the amides piplartine and piperlonguminine isolated from Piper species for controlling L3 and L4 of Aedes aegypti (L.) was assessed through bioassays at concentrations ranging from 1 to 300 g/l ml. Piplartine reduced the mosquito development period and caused larval mortality only at concentrations > 100 microg/ml, whereas pipe...

In total, 183,602 female culicine mosquitoes were captured by Mosquito Magnet, black light, and New Jersey light traps, and manual aspiration of resting blood-fed mosquitoes, in the Republic of Korea from 2008 to 2011. Culicine mosquitoes were identified to species, placed in pools of up to 30 mosquitoes each, and screened for flavivirus RNA by usi...

We assessed the potential for vacant lots and other nonresidential settings to serve as source environments for Aedes (Stegomyia) aegypti (L.) (Diptera: Culicidae) in Mérida City, México. Mosquito immatures were collected, during November 2011-June 2013, from residential premises (n = 156 site visits) and nonresidential settings represented by vaca...

The efficacy of using predators for the biological control of mosquito disease vectors will be reduced if mosquito larvae respond to predator presence. The larvae of two mosquito species were investigated to study whether they responded to predator kairomones by increasing surface filter-feeding, which is a less active and thus less risky feeding s...

The small genus Trichorhynchiella Fain, 1995, including two species of permanent bird ectoparasites belonging to the family Harpirhynchidae (Acariformes: Cheyletoidea), is revised. The generic diagnosis is emended. The type species, Trichorhynchiella paddae Fain, 1995 from Lonchura oryzivora (L, 1758) (Passeriformes: Estrildidae) from Southeast Asi...

Embryos of Lucilia (Phaenicia) sericata (Meigen) (Diptera Calliphoridae), the green blowfly, were successfully cryopreserved by vitrification in liquid nitrogen and stored for 8 yr. Embryos incubated at 19 degrees C for 17 h after oviposition were found to be the most appropriate stage to cryopreserve. Removal of the embryonic surface water was don...

The residual efficacy of lambda-cyhalothrin sprayed on foliage was evaluated against various mosquito species in sections of forest in Cairns, Queensland, Australia Weekly sweep-net collections in treated and untreated areas before and after spraying showed 87-100% reductions in mosquito numbers for the first 9 wk postspray. After that period, redu...
