Role of some environmental factors on the breeding activity of Anopheles arabiensis in New Halfa town, eastern Sudan
AbstractAnopheles arabiensis breeding was studied during March 1999-June 2000 in New Halfa town. Of 3642 anopheline larvae collected, 3633 [99.75%] were A. arabiensis: 82.49%, 11.56%, 3.08% and 2.88% of the larvae were collected from shallow sunlit pools resulting from pipes leakages, rain pools, irrigation canals and man-made pools respectively. The overall mean density was 24.34 larvae/10 dips: 40.73 during the rainy season, 30.45 during irrigation and 13.10 in the dry season. Water for crop cultivation increased the relative humidity [P = 0.013] and both factors enhanced A. arabiensis breeding [P < 0.005]. There was no significant difference between the rainy and irrigation seasons. A. arabiensis breeding in this area has become perennial as a result of crop irrigation

Laboratory and field evaluation of two formulations of Bacillus thuringiensis M-H-14 against mosquito larvae in the Islamic Republic of Iran, 2012 Gezelbash, Z.; Vatandoost, H.; Abai, M.R.; Raeisi, A.; Rassi, Y.; Hanafi Bojd, A.A.; Jabbari, H; Nikpoor, F. (2014)Due to low efficacy in the field of a local commercial product of Bacillus thuringiensis M-H-14 [Bioflash[registered sign], a study was designed to assess its efficacy in laboratory, glass standard aquarium, semi-field and field conditions at both target and higher dosages against immature stages of Anopheles spp.and Culex spp.In laboratory conditions, the LCvalues of wettable powder and granule formulations were 227 and 1031 ppm respectively against a susceptible strain of An.stephensi.Following application of wettable powder and granules ...
