Spodoptera eridania

Spodoptera eridania View in CoL

The eggs of S. eridania are light green and somewhat shiny, and as in other Spodoptera species are deposited in one or occasionally two or three layers. Egg masses are generally covered with filamentous modified scales. They are hemispherical and flattened at the base. They may be covered with abundant filamentous scales ( Fig. 6A View Figure 6 ). Their average diameter and height are 480.3 µm (430–521) and 370.2 µm (292–420), respectively ( Fig.6B View Figure 6 ). The average number of micropyles is 3.9 (2–5) ( Fig. 6D View Figure 6 ) and they are surrounded by a rosette composed of 10.6 (8–14) primary cells ( Figs. 6B and 6C View Figure 6 ). The distal ends of the rosette have rounded petals on their outer edge ( Figs. 6B and 6C View Figure 6 ). The number of ribs in the eggs of this species ranges from 51 to 52, which falls within the range of S. albula and S. cosmioides . The aeropyles are arranged at the junction of the ribs and cross-ribs. The texture of the chorion surface, observed at a magnification of 12,000x is rugous.
