Examples of <strong>impacts</strong> of climate <strong>change</strong> on insects<br />
• Reduced overwintering mortality from cold weather events.<br />
• Faster development/ more generations per season due to<br />
warmer <strong>and</strong> longer summers.<br />
Ips pine bark beetles could move from<br />
2 generations per year to 3 gens/yr.<br />
in central <strong>and</strong> northern MN.<br />
• Disrupt the phenological synchrony between insects <strong>and</strong> their<br />
natural enemies.<br />
Population increases of larch casebearer are<br />
thought to be caused by warmer temperatures<br />
that favor the defoliator over its parasites.
