Spodoptera cosmioides

Spodoptera cosmioides View in CoL

The eggs of S. cosmioides display several colors, ranging from green, grey, and brown to non-glossy pinkish-brown, and they are laid in two to three layers.The egg masses are generally covered with filamentous modified scales ( Fig. 5A View Figure 5 ) characteristic of many Spodoptera species. Aeropyles (0.5-1.5 µm) are distributed on the junction points where the ribs and cross-ribs converge, as well as, on the vertical ribs of the outer third series of cells from the micropylar region ( Figs. 5C and 5D View Figure 5 ). The average numbers of ribs and micropyles are 48 (46–54) and 3 (3–4), respectively, and the micropyle is surrounded by a rosette composed of 10 (8–12) primary cells ( Fig. 5B View Figure 5 ). The distal ends of the primary petals of the rosette are rounded ( Fig.5B View Figure 5 ). The texture of the chorion surface, observed at a magnification of 12,000x, is irregularly rugose ( Fig. 5E View Figure 5 ).
