Essay On Mosquito

Mosquito as a holobiont undergoes metamorphic transition from larval to adult stage. Microbial inhabitants of mosquito and its larvae refer to the microbial communities which colonise in the target organism. The microflora associated with larvae is replaced in the adult mosquito with new set of microbes. This variation in the microbiota is due to the significant changes in host mosquito life according to the changes in the environment and feeding habits. This process of microbial cleaning and acquisition is termed as gut sterilization. During their larval stage mosquito mainly consume bacteria and planktons as nutritive resources. This paves the initial stage of bacterial colonization that adds to resident members. Among the microbes the bacteria colonize more in the midgut than in salivary gland and

Whereas mosquito gut showed a low bacterial diversity that consist primarily of gram negative aerobes and facultative anaerobes. This was justified by the findings of (Osei-Poku et al. 2012) in which they observed that mosquitoes tend to have similar diets during different life stages.

Nature of Anopheline gut

Genus Anopheles which comprises approximately 430 species are cosmopolitan in distribution (cdc) Each mosquito genus has specific ecological preference for selecting its habitat. For example genus Anopheles, are mostly observed in clear water exposed to direct sunlight (Clements 1999). As non selective filter feeder larvae, Anopheles indiscriminately feed on inorganic matter like dust and organic matter such as filamentous algae, fungi, rotifers, cyanobacteria, zooflagellates and crustaceans present in water. They utilize mouth brushes or lateral palatal brushes as paddles to create currents by using energy for ingesting food particles (Eyob Chukalo and Dawit Abate
