Silencing the alarm

An enzyme in the saliva of certain insects prevents their food plants from warning neighboring plants of an attack.

Oh Good, Trillions of Cicadas Are Coming

They’ll make their arrival in the region sometime in May or June.

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.
