Abstract

We investigated the external morphology, eye size, facet size, and numbers of ommatidia and ommatrichia of the compound eyes of Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae), Bactrocera tau (Walker) and Bactrocera dorsalis (Hendel) using light and scanning electron microscopy. There significant differences were found between females and males and between the 3 Bactrocera species. The results contribute to the further exploration of the relationship between the ultrastructural dimensions of the compound eye features and the visu­ally-based behaviors of these 3 Bactrocera species.

 

Sumario

Investigamos la morfología externa, el tamaño de los ojos, el tama­ño de las facetas y el número de ommatidia y ommatrichia de los ojos compuestos de Bactrocera cucurbitae (Coquillett) (Diptera: Tephriti­dae), Bactrocera tau (Walker) y Bactrocera dorsalis (Hendel) usando microscopía de luz y electrónica de barrido (SEM). No se encontraron diferencias significativas entre las hembras y los machos de las 3 espe­cies de Bactrocera. Los resultados contribuyen a la investigación adi­cional de las relaciones entre las dimensiones ultraestructurales de las características de los ojos compuestos y el comportamiento basado en lo visual de estas 3 especies Bactrocera.
