Abstract:Periplancta americana (L.) at different stages of development were exposed to 5 different light regimens for 24 h: UV vs. dark; "filtered" light (above 345nm) vs. dark; UV vs. "filtered" light white light vs. dark; and UV vs. white light. (of equal intensity). Early instars avoided UV more quickly than "filtered" or white light, given the opportunity to escape into darkness. However, when forced to choose between UV and "filtered" or white light, early instars showed delayed avoidance or no avoidance. The same general patter held for older instars except that avoidance responses occurred more quickly. When forced to choose between UV and white light of equal intensity, no avoidance occurred in any in star except the 5th. Mortality was greater than 90% in 1st to 5th-in star cockroaches regardless of the UV avoidance, though older instars required up to 1 month to reach 90% mortality, whereas in 1st and 2nd instars 100% mortality occurred within 4 days. Sixth and older instars exhibited very low mortality except in the UV vs. white light treatment where greater than 90% mortality occurred within 4 days.
