Mosquito Survey and the Difficulties of Long Lasting Insecticide Nets Usage in Ifite Awka, Awka South LGA, Anambra State Nigeria
Abstract:
Background: The risk of mosquito-borne illnesses being transmitted from persons to persons via infected mosquito bites makes mosquito presence in educational settings a serious hazard to the health of students and other occupants. was carried out between October and December 2021
Methods: Mosquitoes were collected through three major sampling methods namely; Pyrethrum Knockdown Collection (PKC) for the indoor mosquitoes, Human Landing Catch (HLC) and larval sampling for outdoor mosquitoes.
Result: A total of 440 mosquitoes were collected from the sample locations and results from the study showed that the predominant species was Culex quinquefasciatus 323/440 (73.4%) followed by Anopheles gambiae 99/440 (22.5%), Mansoni africana 16/440 (3.6%) while Aedes aegypti was the least 2/440 (0.5%). There was a significant difference in abundance between the four mosquito species (p<0.000). With regards to hostels, the abundance of mosquitoes in Godfelic hostel was not significantly different (p=0.874) and highest compared to other sample locations. hostels were sampled. In the larval habitats sampled, the three mosquito genera present were Anopheles gambiae, Culex quinquefasciatus and Mansoni africana. Result on the challenges of using LLINs in malaria control using a questionnaire revealed that out of the 99 respondents, 32.73% implicated adverse reactions of chemical in nets, 27.27% complained of itching while using the nets, 34.55% complained of increase in body temperature and 5.455% complained of sneezing.
Conclusion: The findings of this study will be useful in developing and implementing a larval management strategy as a means of vector management, and it is recommends that ongoing campaigns to promote the use of long-lasting insecticidal nets (LLINs) to prevent malaria should be supported.
