The Density of Anopheles Mosquitoes in Correlation to Malaria Cases and Some Environmental Factors in Elnhoud Town
This work aimed at studying the population density of Anopheles mosquitoes and the incidence of malaria, during July–December 2017 and 2018. The study was conducted in Elnhoud Town. The mean temperature and amount of rain fall were also recorded during this study. The results showed that the Anopheles mosquitoes (Larvae and Adults) were recorded in all available breeding said and resting place. The numbers recorded for this vector species were higher during September, and August than during the other months in Elnhoud town, during 2017. In 2018, the means recorded for this species were higher during September and October than during other months. The species were not recorded during November and December 2018 in all town. The overall mean number of the vector recorded in all town was higher in 2018 than in 2017. The number of malaria cases recorded in the town was highly correlated with the number of vectors recorded and with the environmental factors (means temperature and the amount of rain fall), during 2018, the amount of rainfall was high and this may have led to the increase of the breeding sites, and hence, the malaria cases recorded. During both years the numbers of vectors and of the resulting malaria cases were highly in the town.
