| Abstract: | "Although adult sycamore lace bugs Corythucha ciliata (Say) show no sign of aggregation, nymphs at all developing stages are gregarious. When an individual nymph in the center of a colony was squashed with a needlepoint, proximate nymphs showed evasive behavior. The same evasive reaction was produced by exposing aggregated nymphs to nymph hexane extract. The active component, E-3,7-dimethyl-2,6-octadien-1-ol, geraniol, was responsible for the evasive behavior, and identified as the alarm pheromone. One nanogram of the alarm pheromone elicited activity similar to that in a third instar nymph. Presence of 2-acylcyclohexane-1,3-diones and their 4-hydroxy analogues are reconfirmed as nymph-specific components, though their biological significance remains unknown" |
