White grubs
Abstract
White grubs are soil-dwelling larvae of insects commonly known as “May beetles” or “June beetles” in the family Scarabaeidae. These grubs feed on herbaceous plant roots and other soil organic matter, but will also feed on the roots of woody plants, including all types of coniferous and hardwood seedlings in nursery settings. Numerous genera known to cause damage in forest nurseries include the common Phyllophaga (with more than 100 different species), Polyphylla, Diplotaxis, Dichelonyx, Serica, Cotalpa, Anomala, and others.
