In moth pheromone communication signals, both quantitative and qualitative intraspecific differences have been found across geographic regions. Such variation has generally been hypothesized to be due to selection, but evidence of genetic control of these differences is largely lacking. To explore the patterns of variation in pheromone signals, we quantified variation in the female sex pheromon...

We evaluated the effectiveness of using a blend volatiles that attract Cotesia vestalis , specialist parasitoid wasp diamondback moth (DBM) larvae, to control DBM larvae on cabbage plants under open field conditions. set three dispensers synthetic C. attractant together with one sugary-food feeder in plot (10 m × 1 m; treated plot) side pesticide-free agricultural (approximately 20 m) from June...

Four non-host plant extracts from Bifora radians, Arctium lappa, Humulus lupulus and Xanthium strumarium, were tested against adult grape berry moths, Paralobesia viteana, for their potential as repellents or oviposition deterrents. Responses were compared with those elicited by the major component of the P. viteana sex pheromone. Moths of both sexes exhibited varying electroantennogram (EAG) r...

Keywords: American black bear Aversive conditioning treatments Foraging theory Urban ecology Ursus americanus a b s t r a c t Human-dominated landscapes offer spatially concentrated and reliable food resources that attract wildlife and lead to human–wildlife conflicts. Conflict management is often directed at humans (e.g., education) to reduce attractants, or foraging benefits to wildlife, or a...

Freshly released eggs of the marine brown alga Dictyota dichotoma secrete a substance that attracts spermatozoids. This compound has been identified as n-butyl-cyclohepta-2,5-diene. It is closely related to attractants in several other brown algae and confirms that a relation exists between phylogeny and attractant compounds.

Wildlife-aircraft collisions (wildlife strikes) pose safety risks to aircraft and cost civil aviation over $390 million annually in the USA. We reviewed the results of prior studies to summarize the vegetation management techniques that have proven effective for wildlife strike reduction or have shown potential for achieving the same goal. Habitat components that may affect wildlife use of airp...
