Penn State A plant may start to prime its defenses as soon as it gets a whiff of a male fly searching for a mate, according to Penn State entomologists. Once tall goldenrod plants smell a sex attractant emitted by true fruit fly males, they appear to prepare chemical defenses that make them less appealing to female flies that could damage the plants by depositing eggs on them, the researchers said. "It's become increasingly clear in recent years that plants are responsive to odors,"...

Scientists at the University of Liverpool have found that male mice produce a pheromone that provokes females and competitor males to remember a preference for the place where the pheromone was previously encountered. Some animals, such as moths, use a sensitive tracking system to trace airborne sex pheromones to the source, while others, such as snakes, follow trails of pheromones left on the ground. A team from the University's Institute of Integrative Biology has discovered that mice...
