Cotton balls as an oviposition substrate for laboratory rearing of phytophagous stink bugs (Heteroptera: Pentatomidae)
Annals of the Entomological Society of America 100 (5), 745-748
Abstract: Studies were conducted to test the suitability of absorbent cotton as an oviposition substrate for phytophagous stink bugs (Heteroptera: Pentatomidae). In confined boxes, >80% of total egg masses of Euschistus heros (F.), Dichelops melacanthus (Dallas), and Thyanta perditor (F.) were laid on cotton; for Piezodorus guildinii (Westwood) and Chinavia impicticornis (Stål), >60%. However, Nezara viridula (L.) and Edessa meditabunda (F.) did not oviposit on cotton balls, but instead on the box walls, on filter paper, or on food. Newly hatched nymphs successfully (>95%) left the eggshells despite the presence of cotton fibers around the egg masses.
