Nematode odors offer possible advantage in the battle against insect pests

Gardeners commonly use nematodes to naturally get rid of harmful soil-dwelling insects. A new study published today in the journal Functional Ecology revealed that these insect-killing nematodes also produce distinctive chemical cues, which deter Colorado potato beetles and make potato leaves less palatable to them.
