EUROPEAN RED MITE CONTROL ON APPLE, 2010

Silicas for control of the poultry red mite Dermanyssus gallinae

Control of the poultry red mite Dermanyssus gallinae is a challenge for organic as well as conventional egg producers. In organic agriculture, control should be attempted by mechanically acting substances (e.g. oils or diatomaceous earth), before acaricides are applied. Diatomaceous earth (DE) without acaricides was at least as effective as DE supplemented with pyrethrum or essential oils and a...

APPLE: Malus domestica Borkhausen, 'Red Delicious' MITE FLARING POTENTIAL AND EFFECTS ON BENEFICIALS OF VARIOUS COMPOUNDS, 2003

The objective of this study was to determine the potential for several new CM products to flare ERM populations, especially those in the neonicotinoid class, by comparing them to other CM insecticides from the organophosphate, carbamate and pyrethroid classes. Treatment timing was designed to simulate application for CM control. The test materials were applied to 16-yr-old 'Red Delicious' apple...

The Economic Threshold with a Stochastic Pest Population an Application to the European Red Mite

This paper applies option value theory to determine the timing and value of pesticides in controlling crop damage. Entomologists and economists have both sought to determine '~ction" or 'economic" thresholds which would trigger the application of a pesticide, or an alternative pest control policy. These concepts are reviewed, and the differences arising in each discipline are noted. Two mathema...
