Foxes are always the first to arrive, lured by the scent of horse meat, beef and freshly killed chicken left at the edge of a desert road. Soon they are followed by other predators: wolves, jackals, hyenas and occasionally even a leopard. One after another, they partake of the roadside feast, while ignoring the nearby human observers. This remarkable nocturnal ritual is repeated once every two weeks at five locales in the bleak wastes of the Negev and Judean deserts, supervised by Israel's Nature Reserve Authority...
...resinous scent of hot green summer flowed in waves across the sprawling north campus of the University of Michigan. But the obsessed, drifting in and out of the five-building brick residence complex perched above Ann Arbor, hardly noticed. This was a weekend devoted to the joys of combat...
...Penn Station, from which the Crescent pulls out each day at 2:45 p.m. under Amtrak's auspices. (Southern takes over at Washington.) Rather, for the passenger embarking on the 1,378-mile, 28-hour trip to New Orleans, the Crescent City, there is the comforting scent of soap and polish, the promise of solicitude, of pride and punctuality. Not to mention a rockaby sleep, punctuated by the occasional hissing stop, and a glimpse of some dimly lit Southern station in the dark...
...with female pink bollworm moth pheromone that the male moths sometimes go on indiscriminate sex orgies. They try to mate with sticks, stones, vegetation or anything else in the vicinity. However they react, they are seldom able to find the available females; they soon become so accustomed to the scent that they no longer respond to it. The result: a sharp drop in the population of caterpillar young -and crop damage. In field tests near Blythe, Calif., last year, only 10% of cotton crops treated with Gossyplure were damaged, compared with 80% in unsprayed areas...
...vegetation and had no effect on other species of insects. (Standard chemical sprays used on cotton fields also kill insects that are beneficial to the crop.) It is conceivable, so to speak, that the bollworm could evolve immunity to its own sex pheromone-for example, by producing a different scent. But scientists could then synthesize the new pheromone and continue to control the frustrated moths...
