In what way does pheromone work on the same species of plant or animal?

We’ve now had a way of working on insects to change their behavior with how to stop locusts swarming, and a possible way of changing crops to help them survive a drought. Now here’s an ingenious piece of research that tries to do both at the same time. To control insect activity and help the crop grows through one treatment. It’s all down to pheromones, the chemical signals that allow members of the same species of plant or animal to communicate. They’re as powerful as hormones, which travel in the blood, but unlike hormones they travel through the air. And it’s the 50th birthday of their discovery this year.

The Number One Male Country Artist of the year was 34-year-old Georgia native Jason Aldean. He earned his big break with his fourth album, "My Kinda Party". The set has sold more than two million copies in the U. S. alone and ranks at Number Four on the all-genre Billboard 200 year-end chart. Two songs from the album reached Number One, including the Country-rap hit, "Dirt Road Anthem," which also tops Billboard’s year-end Ringtones chart.
