| chemistryvis-à-vis maternalism in lace bugs (heteroptera: tingidae): alarm pheromones and exudate defense incorythucha andgargaphia species. | the hawthorn lace bug,corythucha cydoniae, and the eggplant lace bug,gargaphia solani, possess alarm pheromones that are produced in dorsal abdominal glands (dags). wheng. solani nymphs are grasped, they emit secretion from both dags; the posterior dag secretion alone elicits alarm, but the anterior dag secretion may hasten the response. inc. cydoniae, the response is due to a synergism between the anterior and posterior dag secretions, and nymphs are apparently unable to voluntarily release the ... | 1991 | 24258608 |
| acyclohexanediones from setal exudate of hawthorn lace bug nymphcorythucha cydoniae (hemiptera: tingidae). | the three major components of setal exudate from nymphs of the hawthorn lace bug,corythucha cydoniae, were identified as 3,6-dihydroxy-2-[1-oxo-6(e),8(e)-tetradecadienyl]cyclohex-2-en-1-one; 3,6-dihydroxy-2-[1-oxo-dodecanyl]-cyclohex-2-en-1-one; 3,6-dihydroxy-2-[1-oxo-8-dodecenyl] cyclohex-2-en-1-one. an additional 10 minor components were partially characterized. | 1989 | 24272424 |
