Background Malarious areas in Iran are close to Afghanistan and Pakistan that urge the researchers to extend their knowledge on malaria epidemiology to the neighboring countries as well. Vectorial capacity differs at species or even at population level, the first essential step is accurate identification of vectors. This study aimed to identify Anopheles species composition in selected malariou...

Malaria transmission was studied from July to September, 2002 in three villages of the Tesseney sub-zone, in the western lowlands of Eritrea. The three methods used for mosquito collection were light traps, pyrethrum spray catches, and pit shelter collections. All anopheline mosquitoes that were collected belonged to the Anopheles gambiae complex and they were identified by PCR as the sibling s...

Pyrethroids are synthetic chemicals similar to pyrethrins in the pyrethrum extract which is obtained from Chrysanthemum plant. Historically, pyrethroids have been classified into two classes that differ in their chemical structure and symptoms of exposure: Type I pyrethroids include allethrin, tetramethrin, d-phenothrin, permethrin, and bioresmethrin. Type II pyrethroids include cypermethrin, c...

Cytochrome P450-dependent monooxygenases are important in the activation and detoxiWcation of numerous insecticides. In this study, a Drosophila melanogaster Cyp6d4 null mutant was used to determine the role of this P450 in insecticide metabolism. This null mutant was generated by imprecise excision of a mobile P element located upstream to the P450 gene Cyp6d4. Comparative analysis between the...

Pyrethrins are terpenoid esters derived from the flowers of Chrysanthemum cinerariifolium. The pyrethrin family includes six similar compounds containing a cyclopropane core, named pyrethrin 1 and 2, cinerin 1 and 2 and jasmolin 1 and 2. Pyrethrins both repel and kill insects by delaying the closure of voltage-gated sodium ion channels in the nerve cells. The insecticidal and insect repellent p...

UNLABELLED PREMISE OF THE STUDY Nuclear microsatellite primers were developed for the weedy herb Anacyclus clavatus to study the genetic structure of hybrid zones with closely related taxa in the western Mediterranean Basin, where different floral phenotypes are present. • METHODS AND RESULTS We obtained two microsatellite libraries using next-generation sequencing and Sanger sequencing of...
