Science Sunday. Interesting topic about plants making noises and the impact on moths. I knew I was hearing noises in the garden haha. 
Article: When They Hear Plants Cry, Moths Make a Decision - The New York Times
Quote: In an earlier study, researchers showed that some plants emit ultrasonic clicks when under stress. Those sounds are imperceptible to people but fall within the hearing range of other animals, including insects.
Now I know why they never lay eggs on my plants … 
Interesting. Buuuuut I saw plenty moth & worm activity in a wet tripical rainforest & plants that were never dehydrated. Possibly less than my hot dry outdoors but not remarkably so; I found insect pressure far lower in Hawaii than California… which I attribute to CA being more populous in plants people and pests, HI being isolated geographically, more beneficial insects in HI due to climate & less pesticide use per area…
