899 Abstract The maxillary stylets and maxillary palps of three species of mosquitoes belonging to genus Anopheles, viz., Anopheles culicifacies Giles, Anopheles fluviatilis James Anopheles subpictus Grassi have been studied using scanning electron microscope. The studies reveal the presence of lateral teeth and absence of mesial teeth on the maxillary stylets. The number, shape and size of lat...

In human malaria, transmission intensity is highly dependent on the vectorial capacity and competence of local mosquitoes. Most mosquitoes are dead ends for the parasite, and only limited ranges of Anopheles are able to transmit Plasmodium to humans. Research to understand the determinants of vectorial capacity and competence has greatly progressed in recent years; however, some aspects have be...

This study contributes to knowledge of Anopheles species, including vectors of Plasmodium from the western Brazilian Amazon in Porto Velho, Rondônia State. The sampling area has undergone substantial environmental changes as a consequence of agricultural and hydroelectric projects, which have caused intensive deforestation and favored habitats for some mosquito species. The purpose of this stud...

Zika virus (ZIKV) is a vector-borne flavivirus that has caused recent outbreaks associated with serious disease in infants and newborns in the Americas. Aedes mosquitoes are the primary vectors for ZIKV, but little is known about the diversity of mosquitoes that can transmit ZIKV in North America. We chose three abundant North American mosquito species (Anopheles freeborni, Anopheles quadrimacu...

Anopheles mosquitoes transmit malaria, a major public health problem among many African countries. One of the most effective methods to control malaria is by controlling the Anopheles mosquito vectors that transmit the parasites. Mathematical models have both predictive and explorative utility to investigate the pros and cons of different malaria control strategies. We have developed a C++ base...

Wolbachia are maternally transmitted intracellular bacteria that invade insect populations by manipulating their reproduction and immunity and thus limiting the spread of numerous human pathogens. Experimental Wolbachia infections can reduce Plasmodium numbers in Anopheles mosquitoes in the laboratory, however, natural Wolbachia infections in field anophelines have never been reported. Here we ...

two organochlorine, one organophosphate, two carbamate and two pyrethroid insecticides have been studied for their comparative study against fieldcollected an.pulcherrimus. the trail was conducted in ghasreghand district, sistan and baluchistan province, southeastern iran using who impregnated papers at the diagnostic dose. results revealed that this species exhibit resistant to 0.4% dieldrin (...

Anopheles squamifemur has been identified from CDC light trap collections carried out at Arca de Israel, a small community located in the extreme north-east of Bolivia (Pando Department) on the banks of the river Madera, on the border with Brazil. Anopheles costai and An. forattinii have been identified in place of An. mediopunctatus which has been removed from the Bolivian list of Anopheles sp...

Anopheles populations were monitored for one year in 2 neighboring villages in Faiyum Governorate, Egypt, to study factors causing differences in malaria prevalence. Both villages contained the following speciei: Anopheles pharoensis, An. sergentii, An. multicolor and An. tenebrosus. Abundant larval breeding sites in Abheet, the viliage with the higher malaria rate, accounted for the higher adu...
