Very recently, the Asian malaria vector (Anopheles stephensi) was stably transinfected with the wAlbB strain of Wolbachia, inducing refractoriness to the human malaria parasite Plasmodium falciparum. However, conditions in the field can differ substantially from those in the laboratory. We use the rodent malaria P. yoelii, and somatically transinfected An. stephensi as a model system to investi...
AgDNV is a powerful gene transduction tool and potential biological control agent for Anopheles mosquitoes. Using a GFP reporter virus system, we investigated AgDNV host range specificity in four arthropod cell lines (derived from An. gambiae, Aedes albopictus and Drosophila melanogaster) and six mosquito species from 3 genera (An. gambiae, An. arabiensis, An. stephensi, Ae. albopictus, Ae. aeg...
Optically active (1S,2'S)-2-methylpiperidinyl-3-cyclohexen-1-carboxamide (SS220) is a new synthetic arthropod repellent. A three-step synthesis based on a chiral Diels-Alder reaction and diastereomeric resolution of 2-methylpiperidine was developed to prepare the compound. Quantitative laboratory assays using human volunteers compared the effectiveness of SS220 with the commonly used repellents...
Aspergillus niger is a fungus of the genus Aspergillus. It has caused a disease called black mold on certain fruits and vegetables. The culture filtrates released from the A. niger ATCC 66566 were grown in Czapek dox broth (CDB) then filtered with flash chromatograph and were used for the bioassay after a growth of thirty days. The result demonstrated these mortalities with LC(50), LC(90), and ...
Successful development of Plasmodium in the mosquito is essential for the transmission of malaria. A major bottleneck in parasite numbers occurs during midgut invasion, partly as a consequence of the complex interactions between the endogenous microbiota and the mosquito immune response. We previously identified SRPN6 as an immune component which restricts Plasmodium berghei development in the ...
Methanolic extracts of the leaves of Atlantia monophylla (Rutaceae) were evaluated for mosquitocidal activity against immature stages of three mosquito species, Culex quinquefasciatus, Anopheles stephensi, and Aedes aegypti in the laboratory. Larvae of Cx. quinquefasciatus and pupae of An. stephensi were found more susceptible, with LC50 values of 0.14 mg/l and 0.05 mg/l, respectively. Insect g...
Effect of anti-mosquito-fat body antibodies on the development of the malaria parasite, Plasmodium vivax has been studied by feeding Anopheles stephensi mosquitoes with infected blood supplemented with serum from immunized rabbits. Immunogenic polypeptides were identified by western blot. Mosquitoes that ingested anti-fat body antibodies along with infectious blood meal had significantly fewer ...
اهداف. آغشتهسازی البسه نظامی، بهویژه یونیفرمها، به پرمترین بهعنوان تکنیک مفیدی برای مقابله با گزش حشرات و حفاظت فردی سربازان به ثبت رسیده است. هدف از مطالعه حاضر، بررسی تاثیر شستشوی یونیفرمهای آغشته بر دوام و بقای پرمترین و قدرت حشرهکشی آن است. روشها. این مطالعه از نوع مداخلهای تجربی است که به مدت 2 سال طی سالهای 1382 تا 1384 در دو آزمایشگاه در دانشگاه علوم پزشکی تهران به انجام رسیده ا...
malaria is considered a major health problem in iran. there are different methods for vector control. in this study we tested the larvicidal effects of some iranian plants. the methanolic extracts of 11 plants were prepared with percolation method. the larvicidal activities of them against malaria vector, anopheles stephensi were studied using world health organization standard method. all lc50...
background : anopheles stephensi is a sub-tropical species and has been considered as one of the most important vector of human malaria throughout the middle east and south asian region including the malarious areas of southern iran. current reports confirmed an. stephensi resistance to temephos in oman and india. however, there is no comprehensive research on mechanisms of temephos resistance ...
