“…This may explain why Targema et al (2008) reported Wuchereria bancrofti infection to be a major public health problem in Benue State and advocated for the inclusion of the state in the National Programme to Eliminate Lymphatic Filariasis (NPELF). Also working in Ebonyi State, in Nigeria, Amaechi et al (2011) reported Culex quinquefasciatus as the major vector with Anopheles gambiae and Anopheles funestus also playing significant roles in the transmission of lymphatic filariasis in the area.…”

Abstract:Studies on the roles of Anopheles gambiae and Anopheles funestus complexes in the transmission of Wuchereria bancrofti in Makurdi, Nigeria across four localities: High-level, Wurukum, North-bank and Wadata were undertaken from July, 2011 to June, 2012. 1,681 adult female mosquitoes were identified and dissected with the aid of standard keys and procedures to determine their incrimination rates with microfilariae of Wuchereria bancrofti. 1,040 (61.87%) of these were Anopheles gambiae sensu lato while 641 (38.13%) were Anopheles funestus. The results showed a significant difference ( ) 05 . 0  P between the mosquito species and their abundance. The overall microfilarial incrimination rate was 5.77% (97/1,681); Anopheles gambiae s.l. was more incriminated (3.57%) than Anopheles funestus (2.20%). The incrimination rates differed significantly ( ) 05 . 0  P between the two mosquito species surveyed. ANOVA also showed significant variations (P < 0.05) in the microfilarial incrimination rates across the localities and seasons: North-bank locality had the highest microfilarial incrimination rate of 17.23% while mosquitoes from High level, Wurukum and Wadata localities had similar incrimination rates of 3.94%, 3.93% and 3.79% respectively. These rates were higher during the dry season than the wet period. The results revealed potential risk of lymphatic filariasis transmission among residents of Makurdi, since the two Anopheles vectors effectively harboured microfilariae of Wuchereria bancrofti in their salivary glands. However, determination of microfilarial infection rates in human population is recommended in the study area. The results of the present investigation may provide entomological baseline data required for both present and future implementation of vector/disease control interventions in Makurdi

“…This is also in line with the findings that Cx. quinquefasciatus has increased in many towns due to increasing urbanization and resultant proliferation of unsanitary collections of water (Service, 1989) and Amechi et al (2011). As a result of the urban overcrowding, the sanitation services in most of the urban areas, especially at the urban-periphery or squatter settlements are unable to cope adequately with the influx of people (WHO, 2010).…”

Entomological survey of mosquito vectors was carried out to determine species abundance and identify those responsible for the transmission of lymphatic filariasis in Talatan-mafara and Tsafe Local Government Areas of Zamfara State, Nigeria. Houses were randomly selected for mosquito collection. Aerosol (Baygon) was sprayed in the rooms to knockdown indoor resting mosquitoes. A total of 5,230 mosquitoes comprising of 3,104 females and 2,126 males were collected and 1,182 engorged females were dissected to isolate filarial worm, Wuchereria bancrofti. The species of mosquitoes encountered include Culex quinquefasciatus (84%), Anopheles funestus (10%) and Anopheles gambiae sl. (6%). The overall infection and infectivity rates of the mosquitoes with Wuchereria bancrofti were 1.86% and 1.44% respectively. The infection/infectivity rates of Culex quinquefasciatus, Anopheles funestus and Anopheles gambiae sl. were 1.01%/0.51%, 2.97%/2.97% and 4.54%/4.14% respectively.
