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.
Gloomy scale is a pest of deciduous trees that tends to increase in abundance and damage severity in urban areas. This insect feeds on tree cells and tissues, prefers red maple as a host, and may expand its range as climate change continues to alter our environment.
Tar spot is an emerging foliar fungal disease of corn that can reduce crop yield. Incidence and discovery of this disease greatly increased in 2018 and 2019 thanks to a coordinated, multi-state effort that relied heavily on social media and electronic disease mapping.
Citrus greening disease is seriously hindering citrus production in the United States, but generating widespread adoption of the best integrated pest management practices among growers is a challenge, especially when livelihoods are on the line. Recognizing the strong economic factors at play in management decisions will help improve plans for increasing IPM adoption.
A new paper in the Journal of Integrated Pest Management highlights the importance of people in successful integrated pest management programs.
