Histologically, the compound eye of the Caribbean fruit fly, Anastrepha suspensa (Loew) and the apple maggot fly, Rhagoletis pomonella (Walsh) have the open rhabdom structure composed of 8 retinula cells, the seventh retinula cell being the superior cell and the eighth cell being the inferior cell. This cellular organization is similar to that of the housefly and other Diptera. The compound eye of the Caribbean fruit fly consists of ca. 3600 ommatidia that are 190-260 µm long with each having a hexagonal lens 25-30 µm wide. The apple maggot fly eye is smaller and is composed of ca. 2600 ommatidia that are 150-220 µm long with lenses 25 µm wide. The dorsal quadrant of the eyes of both species would be a suitable site for inserting microelectrodes for recording electroretinograms because the eye is structurally more resistant to depression in this area. Therefore, a minimum of cellular distortion would occur when electrodes are inserted in these quadrants of the compound eye. |
