Black Vine & Strawberry Root Weevil
Description:
Adults emerge mid May to late July. Five to six weeks later, eggs hatch into grubs that search out roots to feed on. Grubs feed all season. The worst injury occurs when overwintering grubs feed on roots in spring; plants may fail to put out new growth and die. Because adults feed only at night (making characteristic notches in foliage) and grubs live in soil, the weevil is often not identified as a problem. Notches in leaves, or wilting (despite ample moisture, especially on container plants) are a sign that these pests are feeding on roots. Weevils increase quickly—as many as 500 eggs per female! They prey on a wide range of trees, shrubs, houseplants and berries.
Solutions:
Because the adults hide during the day in debris at the base of plants, and grubs live in the soil, eating roots, both stages are vulnerable to control by Nema-Ject™ Nematodes.
