Why IPM Adoption is Lower in Developing Countries

Integrated pest management comes with a variety of benefits, but its mix of methods can present complicated choices to growers low on resources and agricultural advice. A new report in the Journal of Integrated Pest Management outlines some potential solutions.

potato psyllid - Bactericera cockerelli

Psyllid Movements Revealed Via Gut Content Analysis

Tracking the movements of the diminutive pests is a challenge, but a new study shows that DNA analysis of psyllid gut contents can reveal what plants psyllids have fed on, thereby pinpointing the non-crop "whistle stops" psyllids make before infesting crop fields.

Japanese beetle infestation on corn silk

New Guide Offers IPM Tips for Japanese Beetles in Soy and Corn

An invasive species established in the eastern United States for more than a century, the Japanese beetle is making its way into Midwestern soybean and corn fields. A new review in the Journal of Integrated Pest Management offers a guide to the pest's biology and behavior and methods to fend it off.

fall armyworm - Spodoptera frugiperda

Mixing Lawn Grass Varieties Could Trim Fall Armyworm Infestations

A simple change in the choice of grass varieties for lawns of St. Augustinegrass could be a key tool for fending off fall armyworm infestations, according to new research. While no single St. Augustinegrass cultivar rises above the rest in resisting infestation, mixing varieties may confer some benefits, as fall armyworms clearly preferred single-cultivar plantings in a series of lab tests.

carrot weevil - Listronotus oregonensis

New Guide Offers Latest in Carrot Weevil Management

Carrot weevil (Listronotus oregonensis) is a pest of carrots as well as parsley and celery. A new profile in the Journal of Integrated Pest Management gathers a variety of IPM methods for fending off carrot weevil and highlights where research is needed to better understand its biology and behavior.

Mosquito Management is Key in Creating Popular Urban Wetlands

A study that shows mosquitoes might benefit from wetland-management tactics aimed at protecting frogs illustrates the complicated ecological dynamics present in urban wetlands. Understanding the habitat requirements and ecological interactions of local mosquito species is critical to balancing such wetlands' risks and benefits.

Mesh to Reduce Bycatch: A Simple Solution to a Sticky Problem

Sticky traps used to monitor orchards for the Asian citrus psyllid often catch an array of larger non-target organisms. But a thin layer of mesh fabric—the same kind used in bridal veils and ballet tutus—makes an effective screen to eliminate most bycatch while still catching the target pests.

Aedes aegypti mosquito

Trap Modifications Collect Mosquito Waste for Virus Detection

Public health officials could soon be able to detect viruses in mosquitoes in the wild much more quickly and easily—thanks to the insect equivalent of a urine test. A new study in Australia shows that two kinds of commonly used mosquito traps can be readily modified to collect mosquito excreta, or liquid waste droplets, to be tested for signs of viruses.

Assay Array: Entomologists’ Lab Tests Expose Insect Secrets

Entomologists can find out a lot about an insect through some simple chemical reactions in a lab. A new review offers a guide to the wide variety of tests, or assays, that can be conducted to measure the fats, sugars, and other compounds in an insect's body—thereby revealing useful clues about how it stores and uses energy.
