| the effects of nosema algerae vavra and undeen (microsporida: nosematidae) pathogen of culex pipiens l.(diptera: culicidae) from egypt on fecundity and longevity of the host. | a microsporidian, nosema algerae vavra and undeen, was found parasitizing larvae and adults of a laboratory colony of culex pipiens l. originated from gharbia governorate. a detailed examination of the developmental stages of the pathogen under light and electron microscopes showed that they are typical of the original characteristics of n. algerae. other observations on the infected individuals revealed that spores of the pathogen were found in all organs of the infected mosquitoes except the n ... | 2000 | 11198385 |
| preliminary field trials with culicinomyces clavosporus against some egyptian mosquitoes in selected habitats. | culicinomyces clavosporus was isolated from diseased larvae of culex pipiens collected from brackish water habitat. pure cultures of the fungus were grown on nutrient agar media. in the laboratory, the egyptian isolate of the fungus was bioassayed against first instar larvae of aedes caspius, cx. antennatus and cx. pipiens. the estimated lc50's for ae. caspius, cx. antennatus and cx. pipiens were 4.4 x 10(2), 7.6 x 10(2) and 11.8 x 10(2) conidia/ml, respectively. field studies were undertaken in ... | 2003 | 12739818 |
