| larvicidal properties of decomposed leaf litter in the subalpine mosquito breeding sites. | the larvicidal properties of the dietary leaf litter originating from the vegetation surrounding the subalpine mosquito breeding sites were investigated by using 10-month decomposed alder leaf litter against different field collections of culicine taxa of various ecological origin (aedes cantans, aedes caspius, aedes cataphylla, aedes detritus, aedes punctor, aedes pullatus, aedes rusticus, anopheles claviger, culex hortensis, culex pipiens, culiseta morsitans). larvae originating from sites wit ... | 2002 | 11804062 |
| differential sensitivity to bacillus thuringiensis var. israelensis and temephos in field mosquito populations of ochlerotatus cataphylla (diptera: culicidae): toward resistance? | in the present study, four populations of the same field mosquito species, ochlerotatus cataphylla, were sampled over the rh6ne-alpes region (france), and their respective sensitivity to the organophosphate temephos and the bacterio-insecticide bacillus thuringiensis var. israelensis (bti) was measured. the results obtained in toxicological tests showed significant differences in the larval sensitivities of the four populations for both insecticides. these differences appeared to be related to t ... | 2007 | 17269473 |
| mosquito species richness, composition, and abundance along habitat-climate-elevation gradients in the northern colorado front range. | we exploited elevation gradients (1,500-2,400 m) ranging from plains to montane areas along the poudre river and big thompson river in the northern colorado front range to determine how mosquito species richness, composition, and abundance change along natural habitat-climate-elevation gradients. mosquito collections in 26 sites in 2006 by using co2-baited cdc light traps yielded a total of 7,136 identifiable mosquitoes of 27 species. commonly collected species included aedes vexans (meigen) (n ... | 2008 | 18714885 |
| long lasting persistence of bacillus thuringiensis subsp. israelensis (bti) in mosquito natural habitats. | background: the detrimental effects of chemical insecticides on the environment and human health have lead to the call for biological alternatives. today, one of the most promising solutions is the use of spray formulations based on bacillus thuringiensis subsp. israelensis (bti) in insect control programs. as a result, the amounts of bti spread in the environment are expected to increase worldwide, whilst the common belief that commercial bti is easily cleared from the ecosystem has not yet bee ... | 2008 | 18941501 |
| direct pcr of indigenous and invasive mosquito species: a time- and cost-effective technique of mosquito barcoding. | millions of people die each year as a result of pathogens transmitted by mosquitoes. however, the morphological identification of mosquito species can be difficult even for experts. the identification of morphologically indistinguishable species, such as members of the anopheles maculipennis complex (diptera: culicidae), and possible hybrids, such as culex pipiens pipiens/culex pipiens molestus (diptera: culicidae), presents a major problem. in addition, the detection and discrimination of newly ... | 2015 | 26663040 |
| mosquitoes (diptera: culicidae) and their relevance as disease vectors in the city of vienna, austria. | mosquitoes (diptera: culicidae) are important vectors for a wide range of pathogenic organisms. as large parts of the human population in developed countries live in cities, the occurrence of vector-borne diseases in urban areas is of particular interest for epidemiologists and public health authorities. in this study, we investigated the mosquito occurrence in the city of vienna, austria, in order to estimate the risk of transmission of mosquito-borne diseases. mosquitoes were captured using di ... | 2014 | 25468380 |
| monitoring of west nile virus in mosquitoes between 2011-2012 in hungary. | west nile virus (wnv) is a widely distributed mosquito-borne flavivirus. wnv strains are classified into several genetic lineages on the basis of phylogenetic differences. whereas lineage 1 viruses are distributed worldwide, lineage 2 wnv was first detected outside of africa in hungary in 2004. since then, wnv-associated disease and mortality in animal and human hosts have been documented periodically in hungary. after the first detection of wnv from a pool of culex pipiens mosquitoes in 2010, s ... | 0 | 25229703 |
| circulation of dirofilaria repens and dirofilaria immitis in moldova. | over the last two decades, a significant spread of dirofilariasis has been observed in eastern and central europe. however, data on the circulation of dirofilaria spp. in moldova were absent although direct neighbor states reported high incidence rates of human dirofilariasis. | 2016 | 27912786 |
| monitoring resistance to bacillus thuringiensis subsp. israelensis in the field by performing bioassays with each cry toxin separately. | bacillus thuringiensis subsp. israelensis (bti) is increasingly used worldwide for mosquito control and is the only larvicide used in the french rhône-alpes region since decades. the artificial selection of mosquitoes with field-persistent bti collected in breeding sites from this region led to a moderate level of resistance to bti, but to relatively high levels of resistance to individual bti cry toxins. based on this observation, we developed a bioassay procedure using each bti cry toxin separ ... | 0 | 24037105 |
