| host-feeding pattern of culex quinquefasciatus say and mansonia annulifera (theobald) (diptera: culicidae), the major vectors of filariasis in a rural area of south india. | culex quinquefasciatus and mansonia annulifera are abundant in the rural areas of kuttanadu, kerala, india. bloodmeal identification for individuals of these species collected in this region was determined by the agar-gel precipitin test. a total of 2,328 blood smears from cx. quinquefasciatus (1,148) and ma. annulifera (1,180) was tested. results showed that cx. quinquefasciatus and ma. annulifera were highly anthropophilic and that human feeding accounted for 74 and 66% of the total bloodmeals ... | 2004 | 15185948 |
| decline of brugian filariasis in cherthala taluk, alappuzha district, kerala. | a total of 4492 persons from 5 panchayats and 1 town were investigated from the brugia malayi most endemic taluk of cherthala, alappuzha district of kerala state. the urban area in cherthala taluk only revealed mf carriers; mf rate was 0.13%. rural areas in cherthala taluk were free from infection. microfilaria rate had declined by 99.5% and disease rate by 90.7% in cherthala compared to 1934 prevalence. shedding of sheath by b. malayi microfilariae was recorded for the first time in india. the ... | 2005 | 17080705 |
| susceptibility status of mansonia annulifera to brugia malayi parasites in cherthala, alappuzha district, kerala. | laboratory studies conducted on ma. annulifera collected from cherthala region, kerala, endemic for brugian filariasis indicated that this species is highly susceptible to b. malayi parasites. the experimental infection index of this species was relatively higher (2.74). no significant loss of larvae during development was recorded. the extrinsic incubation period was estimated to be 8 days. | 1998 | 9838888 |
| biting rhythm of the vectors of malayan filariasis, mansonia annulifera, m. uniformis & m. indiana in shertallai (kerala state), india. | biting activity of mansonioides mosquitoes through all night collections for a period of two years in shertallai region, in south india was studied. m. annulifera bites uniformly throughout the night, with two peaks of activity, one after midnight (24.00-01.00 h) and another before dawn (04.00-05.00 h). m. uniformis was found to be predominantly dusk biting, with its peak of activity between 1800 to 1900 h. m. indiana showed two peaks of biting activity one after dusk (2000-2100 h) and another b ... | 1989 | 2563359 |
| seasonal abundance & biting behaviour of mansonia annulifera, m. uniformis & m. indiana & their relative role in the transmission of malayan filariasis in shertallai (kerala state). | three species of mansonia (mansonioides) mosquitoes, viz., mansonia annulifera, m. uniformis and m. indiana were recorded in the shertallai region of kerala state. m. annulifera and m. uniformis were recorded throughout the year while m. indiana was seasonal and in small numbers. their indoor resting density was 3.29, 0.25 and 0.10 per man per h and the man biting density was 24.67, 12.74 and 0.47 per man per night respectively. vector density fluctuated through seasons and reached a peak during ... | 1991 | 1683653 |
| the resting and house frequenting behavior of mansonia annulifera, ma. uniformis and ma. indiana, the vectors of malayan filariasis in kerala state, india. | mansonia annulifera, was recorded to be an endophilic species, preferring to rest indoors, while ma. uniformis was exophilic, having a predilection for outdoor resting habitats, eg bushes and shrubs. ma. indiana did not show a clear preference to either of these biotopes. in indoor resting collections, the unfed proportion of ma. uniformis was significantly higher during post-dusk compared to day hours (p < 0.05), indicating that this exophilic species enters houses during dusk hours for feeding ... | 1992 | 1359651 |
| epidemiology of brugian filariasis in a rural community of kerala state. | the baseline clinico-parasitological parameters collected during the initial survey and the entomological observations made during the first year as a part of a longitudinal study undertaken in a brugian endemic rural community are presented in this paper. out of the total (11.604) examined population, 8.1 per cent had microfilaraemia and 7.6 per cent had filarial disease. a highly significant (p less than 0.001) relationship of age was observed with microfilaraemia and the disease. the filarial ... | 1989 | 2809139 |
