Prey species commonly use predator-released kairomones (PRKs) to detect risk of predation, yet the chemical identity of PRKs remains elusive. Chemical identification of PRKs will facilitate the study of predator-prey interactions and the risk of predation, and when the prey are pests, will potentially provide environmentally friendly means of pest control. In temporary pools of the Mediterranea...

The susceptibility of adult Culex pipiens s.l., Culiseta melanura and Aedes aegypti to insecticide aerosols in wind tunnel exposures varied with time, depending on the stage of blood meal digestion. Greater than 2-fold differences were observed in the concentrations of malathion and synergized resmethrin required to kill test mosquitoes, depending on whether they had been given a blood meal and...

The present study was carried out in Circeo National Park (Lazio region, Central Italy), in order to collect data about mosquito (Diptera, Culicidae) fauna in a protected area for biodiversity. From 2003 to 2004 seasonal surveys allowed to collect and to identify 380 larvae and 713 adult mosquitoes in 6 sites. A total of 15 mosquito species belonging to 6 genera were recorded; the most abundant...

A total of 38 species mosquitoes the Culicidae family two subfamilies Anophelinae and Culicinae belonging to 6 genera, were identified on territory Kharkiv Region from 2009 2019. Dirofilaria larvae found in 932 insects, which was 4.46 % surveyed mosquitoes. The prevalence infection female by dirofilaria ± 0.24 %, while mean intensity dirofilariae 5.4 2.1. Infection with is currently detected 11...

The infectivity and pathogenicity of newly discovered baculovirus, CuniNPV (family Baculoviridae, genus Nucleopolyhedrovirus) originally isolated from the mosquito Culex nigripalpus Theobald, was evaluated in laboratory bioassys against thirteen species and four genera of mosquitoes native to the northeastern U.S. Purified virus at a dosage rate of 1.6 x 10(7) occlusion bodies/ml with 10 mM Mg2...

Chemical cues play an important role in predator-prey interactions in aquatic environments (e.g., Petranka et al. 1987, Dodson et al. 1994, Wisenden 2000). Predator-released kairomones may induce morphological changes in prey (e.g., Laurila et al. 2004, Von-Bert and Stibor 2006), foraging changes by prey (e.g., McCarthy and Dickey 2002, Turner and Montgomery 2003), and behavioral responses of g...

Risk assessment and vector control programs rely on a comprehensive knowledge of mosquito diversity in different areas. The present study aims to evaluate biodiversity areas Sirjan County, Kerman Province, as one the most important economic zones Iran. Totally 4538 mosquitoes representing 19 species four genera were collected identified. Results showed that Culiseta longiareolata Culex quinquef...

The overwintering ecology of Culiseta melanura was studied in a seasonally flooded evergreen forest swamp in south central Connecticut in an effort to clarify which larval stages successfully overwinter in the northeastern USA, and to determine the degree to which larval development and/or mortality occur during the winter months. A total of 8,626 immature Cs. melanura were collected weekly for...

Mosquitoes are important living organisms that participate in the different levels of food chains. However, many families include vector species capable to transmit viruses, bacteria and parasites both humans animals, threatening public health. The goal this work was describe biological diversity mosquito areas M'sila; Algeria based on ecological nature their habitat. breeding sites found were ...
