Abstract
The mortality of European red mite [Panonychus ulmi (Koch)] eggs on fruit of ‘McIntosh’ apple (Malus domestica Borkh.) in storage increased with continuing exposure to low O2 (1.5% CO2 + 1.0% O2) or conventional controlled atmospheres (5.0% CO2 + 3.0% O2) and with elevated storage temperatures to 7.5°C. Lethality was sufficient to provide commercial control for overwintering populations. Susceptibility of red mite eggs differed among years and orchards within years.Keywords
