Warmer temperatures, caused by global warming, could make pest control more challenging in the Pacific Northwest, theorizes a Washington State University entomologist.

At one time, codling moth developed through just two generations per season in Washington State, and, occasionally, a partial third. Nowadays, the pest develops through a partial third generation most years. Another generation Dr. Vince Jones at WSU’s Tree Fruit Research and Extension Center in Wenatchee, said temperature and daylight (photoperiod) influence when an insect goes into diapause […]
