文摘

In biocontrol, alternative food for predators is normally supplied on the plants. We used the litter as source of alternative food for plant-inhabiting predators. The food in the litter was of superior quality than was the pest. Nevertheless, predators commuted between the litter and above-ground plant parts. Predators controlled thrips better with food in the litter than without it.
