Produce-Loving Pests

Insects may be small, but they can wreak havoc on the environment or on a country's economy.
wreak: 加える、与える、浴びせる
wreak havoc on: 荒らす、惨害を与える

Mark Hoddle, director of the Center for Invasive Species Research at the University of California, Riverside, travels the world, studying and battling insects that devour key exports or ecologically significant plants.
devour: むさぼり食う、がつがつ食う、(…を)滅ぼす、(…を)のむ、むさぼり読む、(…を)食い入るように見つめる、(…に)熱心に聞き入る、夢中にさせる、悩ませる

Hoddle stores samples in his lab so he can study their DNA and donate them to research collections.

He also sometimes traps bugs ahead of time-before they cause problems in the U.S.-and holds on to them for future reference.
ahead of time: 定刻前に

It's hard to predict what the next invasive pest is going to be, he says.

This way, when they show up, I've got them marked as a target.
