As. Ba et Sa. Phillips, DEGRADATION OF RED IMPORTED FIRE ANT (HYMENOPTERA, FORMICIDAE) YOLK SPHERES, The Florida entomologist, 78(3), 1995, pp. 463-466
Transmission electron microscopy reveals that the eggs of the red impo
rted fire ant, Solenopsis invicta Buren, contain yolk spheres that are
evenly distributed throughout the center of the egg. Yolk degradation
occurs sequentially as evidenced by the simultaneous observation of t
hree stages of yolk platelet degradation within the eggs.
