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 (...

A 2-site immunoradiometric assay (IRMA) was performed on the head and thorax of Anopheles culicifacies s.l. and An. pulcherrimus females, the 2 most common anopheline species in the District of Ghassreghand (Baluchistan, Iran), collected during the 2 peak malaria transmission seasons (May and September-October 1991). Positive IRMA results revealed the 2 species as potential vectors of malaria i...

BACKGROUND & OBJECTIVES Mosquitoes transmit diseases to >700 million people annually. Malaria kills three million persons every year, including one child every 30 sec. Worldwide there are >3000 mosquito species. In Iraq, 37 species have been identified in different surveys over several decades. We conducted an entomological survey to determine the mosquito species and their distribution in Iraq...

The present study explored the phylogenetic utility of mt-ND5 gene sequences for mosquitoes in genus Anopheles. Phylogenetic tree employing the Maximum Parsimony methods in PAUP strongly supported the traditional taxonomy of genus. Subgenus Anopheles represented by a single species i.e. Anopheles nigerrimus initially separated out from the rest with a strong bootstrap value of 100. Subgenus Cel...

Anopheles pulcherrimus Theobald has a wide distribution in western Asia and is a potential vector of malaria in Iran. We have examined the rDNA-ITS2 (internal transcribed spacer 2) region of An. pulcherrimus specimens collected during the two peaks of activity (May-June and October-November) from Sistan and Baluchistan province, southeastern Iran. There were no consistent differences between sp...

Hormozgan Province is located in the south of Iran bordering the Persian Gulf. In this area, malaria is still considered a major health problem. In the province, eleven species of Anopheles were identified: An. pulcherrimus, An. sergenti, An. apoci, An. multicolor, An. subpictus, An. turkhudi, An. fluviatilis, An. stephensi, An. d'thali, An. superpictus, and An. culicifacies, among which only t...

A cDNA with 2.3 kb encoding F1-F0 ATP synthase (proton ATPase) beta-subunit homologue was isolated from a testis cDNA library of the sea urchin, Hemicentrotus pulcherrimus. The deduced amino acid sequence consisted of 523 residues which contained a 19-residue amino-terminal signal peptide and a 8-residue glycine-rich consensus sequences. Analysis of poly(A) +RNA and/or total RNA from H. pulcher...

Mosquito breeding within the wastewater irrigation system around the town of Haroonabad in the southern Punjab, Pakistan, was studied from July to September 2000 as part of a wider study of the costs and benefits of wastewater use in agriculture. The objective of this study was to assess the vector-borne human disease risks associated with mosquito species utilizing wastewater for breeding. Mos...

A decapeptide (GFDLNGGGVG) isolated from the solubilized jelly layer of the sea urchin Hemicentrotus pulcherrimus stimulates the respiration and motility of H. pulcherrimus spermatozoa and, in addition, produces a number of biological effects on H. pulcherrimus spermatozoa including increases in cAMP and cGMP levels, activation of a Na+/H+ exchange system, and increases in intracellular pH (pHi...
