Abstract
A study of the impact of construction works on the
mosquito fauna and incidence of human malaria was undertaken
in the Federal Capital Territory (Abuja) of
Nigeria from February 1986 to June 1987.
In summary, a total of 67 breeding sites were
visited out of which 37 (55.2%) were found in Garki
Municipal compared to only 6(8.6%) at Sheda Village.
A total of 2,057 mosquito larvae were collected out of
which 1,284 (61.8%) were Culicine larvae while 793
were Anpphelines. 2,411 adult Culex pipiens fatiqans
were caught from the various outdoor resting places.
The sex ratio, i.e. male:female was estimated to be
1.3:1. of the 40 adult Anopheline mosquitoes caught,
11 were An. fenestus.
The indoor resting Anopheline population was studied
using the Pyrethrum spray-sheet collection (PSC) technique,
259 -female An. gambiae were caught out of which 11 were
sporozuite positive on dissection. The sporozoite rate
of the population for the period April-October 1986
was found to be 4.2%. 65.8% of the total number of
Anopheles gambiae dissected were blood-fed. The bloodfeeding
rates of the population were highest in August
and September - 70.3% and 71% respectively.
The disease transmission potentials of the mosquitoes
for September and October at Garki were 0.08 and 0.03
respectively. 35 Adult Aedes aeqypti were caught feeding
outdoors between 4-7 p.m. at Sheda. 177 malaria patients
were hospitalized in the clinic between January to
December, 1986. The highest percentage in-patient cases
due to malaria, (11.8%) was recorded in June. on blood
examination, 31.3% positive slides were found in the
age group 2-4 years.
