SEASONAL EMERGENCE OF ANOPLOPHORA CHINENSIS:<br />
DEVELOPMENT OF A DEGREE DAY MODEL<br />
The effectiveness <strong>of</strong> all pest m<strong>an</strong>agement strategies depend <strong>in</strong> large part upon proper tim<strong>in</strong>g<br />
<strong>of</strong> <strong>the</strong>ir implementation to co<strong>in</strong>cide with <strong>the</strong> targeted life state. For example, <strong>in</strong>secticidal<br />
control <strong>of</strong> adult beetles may co<strong>in</strong>cide with adult emergence. Moreover, <strong>the</strong> best tim<strong>in</strong>gs could<br />
be predicted by Degree‐day models.<br />
Degree‐day models, also known as phenology models are based on <strong>the</strong> fact that <strong>an</strong> <strong>in</strong>sect's<br />
growth is closely l<strong>in</strong>ked to <strong>the</strong> temperature where it is found. A specific number <strong>of</strong> heat units<br />
are required for <strong>the</strong> <strong>in</strong>sect to complete a certa<strong>in</strong> physiological process.<br />
