Morphology and Morphometry of Aedes aegypti Adult Mosquito.

ABSTRACT

Aim: To study the morphology and morphometry of Aedes aegypti mosquito. Place and Duration of Study Laboratory of St. John’s College, Agra. From June, 2011 to May, 2012. Methodology: 20 male and 20 female adult Aedes aegypti were taken for the study. Head, clypeus, vertex, antenna, maxillary palp, thorax, wings, legs and abdomen were studied. The type of scales, their morphology, bands and patches were observed. Morphometric study was done using Image J software. Kruskal-Wallis one way analysis of variance (ANOVA) was employed. Results: The clypeus of female has two silvery white dots whereas, male had no dots. The vertex of male and female has silvery white flat scales. The size of head, proboscis, maxillary palp, antenna, thorax, its lyre marking and median longitudinal lines were measured. The scales and bristles of thoracic regions were observed. The wing membrane has no white scales. It bears specific venation which had flat scales. The size of the wing, legs, abdomen were measured and their scales were observed. The claws of fore, mid and hind legs varied in male and female Ae. aegypti. Conclusion: This study revealed the morphologic features of Ae. aegypti adult in Agra for better understanding of the key characters.
