| studies on quantitative aspects of the transmission of wuchereria bancrofti. | feeding experiments with anopheles gambiae and culex fatigans infected with wuchereria bancrofti showed that the mosquito females were losing about 20% of their worm burden when they were feeding on a blood chamber as well as on the guinea pig. 6.6% of all mature larvae found in the mosquitoes succeeded in entering the final host. a striking high infection rate was observed in those mosquitoes which refused to feed on a guinea pig. these mosquitoes have also to be considered when the loss of fil ... | 1976 | 941249 |
| behavioral response of host-seeking mosquitoes (diptera: culicidae) to insecticide-impregnated bed netting: a new approach to insecticide bioassays. | the response of anopheles gambiae giles s.s and culex quinquefasciatus say to insecticide-treated netting in a wind tunnel permeated with guinea pig odors was recorded on videotape. with no insecticide present, mosquitoes spent 99% of the time on the netting, either at rest or occasionally walking across it. on nylon netting, permethrin at 50, 400, and 1,000 mg m-2 irritated the mosquitoes, causing them to spend significantly more time away from the netting and relatively more time walking than ... | 1994 | 7908985 |
| olfactory memory in the mosquito culex quinquefasciatus. | the cosmotropical urban mosquito culex quinquefasciatus say (diptera: culicidae) uses chemical cues to locate suitable water pools for oviposition. although gravid females are innately attracted to or repelled by certain compounds, this study found that an individual mosquito's preferences for these odours could be altered greatly by prior experience. mosquitoes reared in water containing skatole, at a level normally repellent to ovipositing females, preferred to oviposit in water containing tha ... | 2001 | 11434554 |
| effect of different hosts on feeding patterns and mortality of mosquitoes (diptera: culicidae) and their implications on parasite transmission. | the host-response to hematophagus insects is still an important parameter in understanding disease transmission patterns. we investigated the feeding and mortality rates of three mosquito species, namely culex quinquefasciatus, aedes aegypti and anopheles arabiensis against three different hosts. | 2010 | 20606966 |
| evidence for a lectin specific for sulfated glycans in the salivary gland of the malaria vector, anopheles gambiae. | salivary gland homogenate (sgh) from the female mosquitoes anopheles gambiae, an. stephensi, an. freeborni, an. dirus and an. albimanus were found to exhibit hemagglutinating (lectin) activity. lectin activity was not found for male an. gambiae, or female ae aegypti, culex quinquefasciatus, phlebotomus duboscqi, and lutzomyia longipalpis. with respect to species-specificity, an. gambiae sgh agglutinates red blood cells (rbc) from humans, horse, sheep, goat, pig, and cow; it is less active for ra ... | 2014 | 25207644 |
| culturing culex quinquefasciatus mosquitoes with a blood substitute diet for the females. | the tropical house mosquito culex quinquefasciatus was cultured by feeding the females on an artificial diet, not on live animals or whole blood. this anautogenous strain has been maintained for more than fifty generations. the blood replacement diet for female mosquitoes, designed to simulate the tonicity and density of host blood, was based on ovalbumin, soya infant formula, globulins and adenosine triphosphate. female adults of cx quinquefasciatus were fed the artificial blood formula from "p ... | 1996 | 8887338 |
