In order to document the diversity and distribution of mosquitoes inhabiting Querétaro State México, collection trips were conducted in all physiographic regions sub-regions state (Sierra Madre Oriental, Central Plateau, Neo-Volcanic Axis). addition, mosquito specimens collected deposited Collection Arthropods Medical Importance (CAIM) re-examined. A total 2718 (570 larvae, 384 larval exuviae, ...

Abstract About 96% of all malaria deaths occur in Africa, and the malignant falciparum also originated on continent. Although only appeared Holocene period, it can be hypothesized that transfer parasites from other primates to humans occurred several times history parallel human evolution. This study develops model examines possible coexistence potential original host apes, ancestors, diverse a...

The spatangoid genus Schizaster Agassiz is recorded, for the first time, from the Lutetian (Middle Eocene) deposits of Sargaz area, south of Kerman, Iran. The Lutetian sediments of Sargaz region contain a rich and divers echinoid fauna represented by Cidaridae, Conoclypeidae, Echinolampadidae, Toxopneustidae, Phymosomatidae and Schizasteridae. Schizasteroid echinoids are an important component ...

background: to study the chemical constituents and larvicidal activity of essential oil extracted from the leaves of coccinia grandis against three mosquito species. methods: essential oil was extracted by hydro distillation using clevenger apparatus and was analyzed for chemical constituents by gas chromatography-mass spectrophotometry (gc-ms). larvicidal activity was recorded after 12 and 24h...

ba ckground: mosquitoes are well known as vectors of several disease causing pathogens. the extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fos- tered environmental deterioration. hence in recent years plants become alternative source of mosquito control agents. the present study assessed the larvicidal and ovipo...
