identification of host blood meal in haematophagous arthropods is an important element in their rule in transmission of vector borne diseases. the effects of post ingestion and physical conditions that killed mosquitoes are stored on the success of detecting blood meal dna of anopheles stephensi and culex quinquefasiatus was investigated by polymerase chain reaction (pcr) amplification at the h...

Mosquitoes are the major vectors of diseases such as malaria, dengue, filariasis e.t.c which led to thousands death yearly. World Health Organisation (WHO, 2005). In Nigeria, repellent activity ointments formulated with Occimum gratissimum oil has been reported against Ae. aegypti and Culex quinquefasiatus mosquito (Esimone et al., 2011). Mechanical aspirator will be use catch blood fed female ...

Alginate encapsulated B. thuringiensis var. israelensis (B. t. i.) self floating type formulations were prepared. Its spore release rate, floating efficacy and larvicidal activity against Culex quinquefasiatus were tested in the laboratory. The larval mortality of 91-100% was induced by the floating formulation with a mean spore release of 3.04 x 10(4)/ml/day from 6th day to 27th day. From day ...

Abstract Background Mosquitoes are vectors for several diseases like dengue, chikingunea, malaria etc. The three important mosquito species in India Aedes aegypti , Culex quinquefasciatus and Anopheles stephensi . Several plant extracts phytoconstituents have been tested antimosquito activity. In our present investigation, we studied, the larvicidal, pupicidal ovicidal activities of successive ...

The effects of post-ingestion and physical conditions under which killed mosquitoes are stored on the success of detecting blood meal DNA of Anopheles stephensi and Culex quinquefasiatus were investigated by polymerase chain reaction (PCR) amplification at the human mitochondrial DNA cytochrome b (cytB) gene. Host DNA extracted from the blood meal up to 33 h post-ingestion in both species acts ...

Background & Objectives: Mosquitoes (Diptera: Culicidae) are medically considered as one of the most important species of insects in terms of disease transmission to human beings; hence, they can be vectors of remarkable diseases such as malaria, West Nile, dengue fever, yellow fever, and filariasis. This study aimed to determine the species diversity and larval habitat characteristics of mosqu...

Nucleotide sequences of the circadian rhythm genes, period and timeless, were studied for the first time in mosquitoes Culex pipiens Linnaeus, 1758. In this work we evaluated variations of the studied genome fragments for the two forms of Culex pipiens (forma "pipiens" - mosquitoes common for aboveground habitats, forma "molestus" - underground mosquitoes). We compared Culex pipiens from Russia...
