Closeup of a elm zigzag sawfly larva, light green and slightly translucent in color, feeding on a green leaf. The larva has eaten a gap into the leaf from the edge that is roughly the shape of the larva but wider. The leaf and sawfly are photographed against a white background.

Here We Go Again: Meet the Elm Zigzag Sawfly, Another Non-Native Forest Pest

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.

Beware, Boxwoods: Another Pest is On the Horizon

Cydalima perspectalis, sometimes known as the box tree moth, is established in Canada and was recently found in the U.S. Feeding by this moth can devastate boxwood plants, which are commonly planted in landscapes across the country. A new review highlights the life cycle and potential impact of this pest and makes recommendations for scouting and management.

The Ambrosia Beetle Megaplatypus mutatus: Tiny but Destructive

Most ambrosia beetles are secondary pests on woody plants in both managed and natural landscapes. However, some of the most impactful invasive species in the world are ambrosia beetles. Megaplatypus mutatus, native to South America, has invaded other regions, and a new article in the open-access Journal of Integrated Pest Management  reviews its potential impact and management strategies.

New Guide Highlights IPM for Boxwood Pests

Boxwood is one of the most widely planted landscape plants in North America. However, it is not without management challenges, specifically from arthropod and disease pests. A new article in the open-access Journal of Integrated Pest Management discusses identification, biology, and management of common boxwood pests.

Another Pest of Pollinators: Small Hive Beetle Management in Honey Bee Colonies

Small hive beetles (Aethina tumida) can cause substantial damage in commercial honey bee colonies in North America. Both larval and adult beetles consume hive products and honey bee eggs and larvae, creating a slimy waste in the process. A new guide discusses the biology and management of these pests and highlights current gaps in our knowledge.
