ABSTRACT
Culex tritaeniorhynchus Giles, 1901 and Culex quinquefasciatus Say, 1823 is an important vector of Japanese encephalitis and Bancroftian filariasis, respectively in India and South East Asian countries. In this paper, we are describing the surface morphology and morphometrics of the egg of C. tritaeniorhynchus in comparison with C. quinquefasciatus for the first time. The results indicated that eggs of both the species appears to be similar to great extent in surface morphology, however, morphometrics provide 56.81% demarking attributes out of 44 attributes at various significant levels (p < 0.05-0.001), i.e., egg length, width and ratio of length/width, attributes of micropylar apparatus including corolla, disc, mound, tubercles size, and length of tubercular rows in micropylar region, size and density of tubercles, exochorionic pore in conical-shaped regions of eggs, and size of tubercular wheel units. Structurally, the additional presence of large tubercles strengthens the micropylar region to bear various collapsing forces in these species.
