Conifer sawflies are common herbivores throughout North America. Typically little more than a nuisance to individual trees, large outbreaks are capable of defoliating thousands of forested acres in a very short time. A new review in the Journal of Integrated Pest Management summarizes what we know about conifer sawflies in eastern North America, provides an identification key for larvae and outlines management options for both managed and natural landscapes.
While their damage may be unsightly, many common caterpillar species that emerge in late summer to munch on tree leaves are generally not a significant threat to tree health. A new guide in the Journal of Integrated Pest Management takes a closer look at these late-season defoliators and offers tips for management.
The elm zigzag sawfly (Aproceros leucopoda) is now established in several places in North America. This non-native forest pest can be a threat to elm species and hybrids and is capable of large defoliation events. Will it turn into a full-blown invasive species, or simply co-exist with native herbivores in natural and urban forests? At this point, we don't know. A new review highlights elm zigzag sawfly biology, ecology, and management strategies in the U.S.
Quinoa's emergence as an attractive, climate-resilient crop in the U.S. has been met with a fresh challenge from a stem-boring fly species, Amauromyza karli, previously known in Canada. While research is scant on this new pest, a new profile in the Journal of Integrated Pest Management outlines what we know—and what we need to find out—about reducing its impact on quinoa.
Lesser mealworm beetles (Alphitobius diaperinus) evolved to live in bird nests, and in broiler chicken houses their populations explode. A new pest profile in the Journal of Integrated Pest Management outlines why lesser mealworms are exceptionally challenging to manage in chicken houses and identifies key research needs for future progress.
