If an agricultural pest can be found quickly enough, control could potentially get rid of it. Unfortunately, often when pests are finally detected, their numbers are large enough to make control difficult. But what if you could detect their presence at low numbers, when control could be more effective?
That is the strategy that Rafael Valentin and co-authors took in using environmental DNA to look for brown maramorated stinkbugs (Halyomorpha halys). By sampling the water used to wash picked crops for evidence of stinkbug DNA, the team were able to pick up indications for the presence of the stinkbug before they actually found the bug itself.
