Comparative Morphogenesis of Antennal Sensilla Between the Leptocybe invasa and Ophelimus maskelli (Hymenoptera: Eulophidae) and its relationship to their vital Capacity

insects. The sensilla have been labelled according to their distribution, size, and shape. May also use scanning electron microscopy to reveal sensory organs. On the antennae of L. invasa , sensilla were dispersed in six different types, while on the antennae of O. maskelli , they were placed in nine different types. According to this study, O. maskelli had more sensilla overall than L. invasa ; along the antenna, O. maskelli had 100 sensilla compared to L. invasa more than 37 sensilla. The results from the measured biological characteristics were explained by the qualitative and quantitative differences in the sensilla types of the two species on the antenna, favouring O. Maskelli . The results tended to show that O. Maskelli was the strongest rival that could displace L. invasa .
