[Culicidae Larvae and Their Seasonal Dynamics in the Region of Fez-Meknes, Morocco].

OBJECTIVE

As part of the prevention of vector-borne diseases in central Morocco, a study of the seasonal fluctuation of Culicidian biodiversity was conducted from November 2015 to November 2016 on four breeding sites located in the city of Fez in central Morocco (Jnan El Alami, Lgaâda dam, Awinat Elhajaj, Douwar Lhandiya Source). The study aimed to improve the knowledge of seasonal dynamics and activity period of Culicidian mosquitoes, in order to target the period of control.

METHODS

Larvae were collected by dipping method at a 15-day interval at least once a month. Statistical analyses were performed using version 3.6.1 of the statistical processing software.

RESULTS

During this study, nine species were found with high monthly and seasonal variations in numbers of each species and from site to site. Predominant species are vectors of disease: , known vectors of West Nile virus, followed by s. l. and that are the main vectors of malaria in Morocco. and reached the highest density in September, while was found in large numbers in February and can therefore emerge in late winter and mid-spring. The lowest number of was collected in November, but increased in September, October and December. s. l. occurred in June, with recurrences in March and July. was found in spring and summer and in abundance in June. However, was only present in September and October. Both and were present in November and February.

CONCLUSION

The results obtained will be an important tool for management and monitoring Culicidae proliferation and can be used to improve the efficiency of control management.
