does autocthonous primary production influence oviposition by aedes japonicus japonicus (diptera: culicidae) in container habitats?aedes (finlaya) japonicus japonicus (theobald) (diptera: culicidae) is recently invasive in north america and has expanded its range rapidly since 1998. throughout its native and expanded range, ae. j. japonicus larvae are commonly observed in many types of natural and artificial water-filled containers that vary in organic matter content and exposure to sunlight. larvae are most often found in containers with decaying leaf material or algae, and we postulated that the added autocthonous primary ...023427654
anopheles (anopheles) petragnani del vecchio 1939-a new mosquito species for germany.the so far known species of the anopheles claviger complex, anopheles claviger s.s. and anopheles petragnani, can only be distinguished by partial overlapping characteristics of immature stages and by nucleotide sequence variation of the genomic ribosomal dna (rdna) internal transcribed spacer 2 (its2) region. the known distribution of an. petragnani is so far restricted to the western mediterranean region, whereas an. claviger s.s. occurs across most of europe, up to the middle east and north a ...201627003404
recently discovered aedes japonicus japonicus (diptera: culicidae) populations in the netherlands and northern germany resulted from a new introduction event and from a split from an existing population.originally native to east asia, aedes japonicus japonicus, a potential vector of several arboviruses, has become one of the most invasive mosquito species in the world. after having established in the usa, it is now spreading in europe, with new populations emerging. in contrast to the usa, the introduction pathways and modes of dispersal in europe are largely obscure.201525608763
evidence that implicit assumptions of 'no evolution' of disease vectors in changing environments can be violated on a rapid timescale.projected impacts of climate change on vector-borne disease dynamics must consider many variables relevant to hosts, vectors and pathogens, including how altered environmental characteristics might affect the spatial distributions of vector species. however, many predictive models for vector distributions consider their habitat requirements to be fixed over relevant time-scales, when they may actually be capable of rapid evolutionary change and even adaptation. we examine the genetic signature o ...025688024
mosquito larvae in tires from mississippi, united states: the efficacy of abiotic and biotic parameters in predicting spatial and temporal patterns of mosquito populations and communities.container systems, including discarded vehicle tires, which support populations of mosquitoes, have been of interest for understanding the variables that produce biting adults that serve as both nuisances and as public health threats. we sampled tires in six sites at three times in 2012 across the state of mississippi to understand the biotic and abiotic variables responsible for explaining patterns of larvae of common species, species richness, and total abundance of mosquitoes. from 498 tires ...201526334813
invasive process and repeated cross-sectional surveys of the mosquito aedes japonicus japonicus establishment in belgium.when accidentally introduced in a new location, a species does not necessarily readily become invasive, but it usually needs several years to adapt to its new environment. in 2009, a national mosquito survey (modirisk) reported the introduction and possible establishment of an invasive mosquito species, aedes j. japonicus, in belgium. first collected in 2002 in the village of natoye from a second-hand tire company, then sampled in 2003 and 2004, the presence of adults and larvae was confirmed in ...201424694576
