Abstract
Aims: The study was conducted between October 2012 and May, 2013 with the aim of determining
the effect of Lambda-cyhalothrin treated blinds on control of malaria infection. 400 blood samples
were collected from 106 households.
Study Design: It is an experimental study involving both intervention and control groups.
Place and Duration of Study: The study was conducted in Malete community in Moro Local
Government Area of Kwara State, North central part of Nigeria between October 2012 and May 2013.
Methods: The study was divided into three phases namely: Pre-intervention, intervention and post
intervention. In pre-intervention, 200 blood samples were taken and stained using Giemsa
techniques to determine the baseline malaria infection. At intervention stage, windows and doors
blinds were treated with lambda-cyhalothrin and in post–intervention another 200 blood samples
were taken after treatment and were stained using Giemsa techniques.
Results: On the overall pre-intervention of malaria parasite was 12.5% and after intervention it
reduced to 8.0%. Out of entire infection rate, 2.5% was documented among students residing in the
western location, 4.5% in the central area while 5.5% was recorded in the eastern part of the study
area. Similarly students within the age bracket 18-22 years recorded the highest rate (14.5%) of
asymptomatic malaria infection followed by those within 23-27 years and >27 years with 12.4% and
8.6% rates respectively. Statistically, there was no significant difference in the distribution of malaria
infection in the study area with respect to age (X2=1.743, P=0.08).Statistical analysis by Chi-square
showed a significant difference in frequency of malaria infection among asymptomatic male and
female subjects (X2=5.743, P=0.04). Statistical analysis by student T-test showed no significant
difference in the prevalence of malaria infection before and after intervention (t=0.3310, P=0.07).
Conclusion: Lambda-cyhalothrin used in this trial study shows a promising future against malaria
vector, most of the blinds treated were made of cotton material because it was the common
material among the inhabitants sampled. Further studies are therefore suggested to investigate the
effect of other clothing materials such as nylon and polyester on malaria infection after treatment
with the same chemical.
