Attraction of female mediterranean fruit flies to the five major components of male-produced pheromone in a laboratory flight tunnel.
Attraction and pheromonal activity of five major identified components of the male-produced sex pheromone of the Mediterranean fruit flyCeratitis capitata to virgin laboratory-reared females was assessed in a laboratory flight tunnel. Dual-choice competitive assays were run to establish a baseline response of virgin females to live male pheromone, individual components, and an ensemble of all five compounds alone (air control) and competitively against one another. Approximately 50% of the females released in the tunnel were captured on leaf models emitting pheromonal odors from five live males. Over 37% of released females responded to an ensemble of five major identified components presented in individual capillaries. Response of females to individual componentsDescription

Terry Pratchett's hilarious take on the Faust legend stars many of the Discworld's most popular characters. Eric is the Discworld's only demonology hacker. The trouble is, he's not very good at it. All he wants is the usual three wishes: to be immortal, rule the world and have the most beautiful woman fall madly in love with him. The usual stuff. But what he gets is Rincewind, the Disc's most incompetent wizard, and Rincewind's Luggage (the world's most dangerous travel accessory) into the bargain. The outcome is an outrageous adventure that will leave Eric wishing once more - this time, quite fervently - that he'd never been born.show more
