This survey will involve collecting larvae of APM in damaged shoots of apple for positive confirmation of all suspect APM observations. Survey should begin during bloom through petal fall, or continue for 4-5 weeks from the start.
Damage is quite noticeable if present.
For project participation, it is recommended that at least 25 trees be observed per site, a minimum of 1 site per county and 3 counties. These counties should be selected from the major apple producing counties of your state. When selecting your sites, emphasis should be put on apple crop situations that use little or no pesticides. It is suspected that APM will not be a problem in most commercial apple orchards that use chemical controls. The larvae is the preferred life stage for this project.
