Part II: Thermal time model <strong>for</strong> ALH<br />
development<br />
<strong>Aster</strong> leafhopper generational<br />
development driven by April<br />
2009 wea<strong>the</strong>r data<br />
•- Egg stage (white); 1 st - 5 th <strong>in</strong>stars<br />
(Brown, Drk. green, green, yellow,<br />
orange); Adult (Red)<br />
Longitude<br />
Is this type of model useful<br />
•- Research purposes – gives<br />
predictions to ground-truth<br />
•- Give growers advanced warn<strong>in</strong>g<br />
of seasonal pest development and<br />
potential <strong>for</strong> migration<br />
Will <strong>the</strong> model accurately predict ALH developmental stage
