In laboratory studies, insecticides (diflubenzuron, novaluron, methoprene and, pyriproxyfen) that have been incorporated into rodent diets were effective as feed-throughs against sand fly larvae. Novaluron also was effective against sand fly larvae at low concentrations and under simulated field conditions. Ivermectin has been shown to be effective as a systemic insecticide, killing 100% of blo...
Background and Aim: Some medically important species of Muscidae and Fanniidae families are among synanthropic flies and can be seen in human habitats therefore they can be mechanical vectors of different pathogenic microorganisms. Identification and determination of species of these flies is essential for any control program planning. This study was conducted to determine the faunal diversity ...
The population-level dynamics of maternally transmitted endosymbionts, including reproductive parasites, depends primarily on the fitness effects and transmission fidelity of these infections. Although experimental laboratory studies have shown that within-host endosymbiont density can affect both of these factors, the existence of such effects in natural populations has not yet been documented...
The elimination of infectious diseases requires reducing transmission below a certain threshold. The Visceral Leishmaniasis (VL) Elimination Initiative in Southeast Asia aims to reduce the annual VL incidence rate below 1 case per 10,000 inhabitants in endemic areas by 2015 via a combination of case management and vector control. Using a previously developed VL transmission model, we investigat...
The occurrence of closely related strains of maternally transmitted endosymbionts in distantly related insect species indicates that these infections can colonize new host species by lateral transfer, although the mechanisms by which this occurs are unknown. We investigated whether ectoparasitic mites, which feed on insect haemolymph, can serve as interspecific vectors of Spiroplasma poulsonii,...
This is the first record for the subfamily Psychodinae from Ecuador and a new species belonging to genus Arisemus, A. triconnectus, is described.
Background and Aim: Sand flies are responsible for transmission of leishmaniasis, papatasi fever and carrion disease. Warning of sand fly population is the first step for the establishment of baseline data for the vector control operations of visceral leishmaniasis (VL). In order to attempt to the difference between species composition and bieocology of sand flies, the comparative research was...
