Effect of JH on the sensitivity of AL interneurons in A. ipsilon males to the sex pheromone blend. The proportion of responding neurons with a certain threshold in treated males is represented in the diagrams. Males were tested 2 days after the treatment. Day 5, −CA + oil, 3-day-old allatectomized males injected with olive oil, n = 73 neurons. Day 5, −CA + JH, 3-day-old allatectomized males injected with JH, n = 70 neurons. Day 2, + JH, 0-day-old control males injected with JH, n = 69 neurons.
