Incidence of climate on the population dynamics of Aedes aegypti (Diptera: Culicidae) in the Ignacio Agramonte health area of Camagüey, Cuba

The Aedes aegypti mosquito transmits three of the most serious viruses (DENV), ZIKV, and CHIKV), causing significant morbidity and mortality in humans worldwide. The objective of this research was to determine the impact of certain climatic variables on the population dynamics of the Ae. aegypti mosquito in the "Ignacio Agramonte" health area of ​​Camagüey, Cuba. A correlation was established between the total number of positive mosquito deposits and three temperature ranges; in addition, the total number of positive deposits was correlated with three humidity levels, as well as with precipitation, wind direction, wind speed and force, and atmospheric pressure. All analyses were performed using Pearson's correlation coefficient.

Finally, a linear regression analysis was performed using the Durbin-Watson statistic and the ANOVA test (Fisher's F-test), which allowed for an analysis of variance. The results showed no significant correlation with any of the temperatures; however, the correlation between the total number of positive deposits and those outside the enclosures was highly significant. In the regression analysis, the model was also highly significant, with a Fisher's F-test significant at the 100% confidence level. Regarding variances, they were significant at the 95% confidence level, except for LAG12VM, where the model trend was significant and increased depending on the mean wind speed and direction frequency, both of which were regressed over 7 months. It is concluded that climate does influence the population dynamics of the Ae. aegypti mosquito.
