| evidence for a male-produced aggregation pheromone in scyphophorus acupunctatus gyllenhal (coleoptera: curculionidae). | olfactory response of male and female scyphophorus acupunctatus gyllenhal (coleoptera: curculionidae) to volatiles released from the same or opposite conspecifics alone, or combined with host plant volatiles, was evaluated in the laboratory and field. we also evaluated the response to synthetic rhynchophorinae pheromones in the laboratory. in laboratory tests, attraction of males and females in y-tube olfactometer to conspecific males was greater than to females and clean air. males and females ... | 2003 | 14503583 |
| factors affecting pheromone release by scyphophorus acupunctatus (coleoptera: curculionidae). | scyphophorus acupuncatus gyllenhal is considered to be the most significant pest of cultivated agaves in the world. recent studies on the chemical ecology of this weevil have shown that males release a pheromone that attracts both sexes. in this study, we investigated the effect of feeding, aging, photoperiod, and time of day on pheromone release by s. acupuncatus males under laboratory conditions. the pheromone released by individual males was sampled using solid-phase microextraction and analy ... | 2009 | 19825297 |
