Usefulness of Stress Indicators in Forecasting Population Trends in Microtus arvalis (Pallas) 1

ABSTRACT The appearance of a stress condition in Microtus arvalis (Pallas) populations was established on the basis of histochemical analyses and correlated with population dynamics. It was found that stress appears only during invasions, i.e. when crop damage has already occurred. Commonly, the pop...

Description
Summary:ABSTRACT The appearance of a stress condition in Microtus arvalis (Pallas) populations was established on the basis of histochemical analyses and correlated with population dynamics. It was found that stress appears only during invasions, i.e. when crop damage has already occurred. Commonly, the population crash occurs 30 to 50 days after the appearance of stress. It is concluded that stress indices can neither be used for warnings nor for long‐term forecasts of outbreaks.
