Building a Better Bee Trap: Researchers Say Bee Bowls Are Overused
In a look at the state of bee monitoring in the U.S., a group of researchers argue the commonly used bowl trap presents too many drawbacks to effectively study bee abundance and diversity.
Rolled Cardboard Makes a Handy Insect-Sampling Tool
A group of researchers gets creative with some simple materials: strips of cardboard, rolled up and tied with string. Affixed to tree trunks or limbs, the "trunk refugia" show promise as a simple and inexpensive tool for sampling tree-dwelling insects and arthropods.
Integrated Pest Management Pays for Midwestern Watermelon Growers
Entomologists at Purdue University have developed a reliable and cost-effective scouting technique for striped cucumber beetle (Acalymma vittatum) in watermelon fields. Researchers working with watermelon growers say the method could significantly reduce the unnecessary use of insecticides to manage the pest.
Spotted-Wing Drosophila: New Seasonal Activity Model Will Aid IPM Efforts
Seven years' worth of trapping data for the invasive spotted-wing drosophila in Michigan offer an enhanced view of the pest's seasonal activity and abundance patterns, a boon for fruit growers and integrated pest management pros in temperate regions.
Large-Scale Study Points to Simpler Trap for Monitoring Brown Marmorated Stink Bugs
Tested in more than 100 locations across the U.S., a clear sticky-panel trap proves effective in attracting brown marmorated stink bugs, putting an easier-to-use tool in the hands of growers and IPM professionals for monitoring populations of the invasive pest.
Counting Ticks on Animals is More Complicated Than It Sounds
Simply counting the number of ticks on a host animal seems like a straightforward task, but an analysis of published tick research finds no single, standard method among scientists. A group of researchers says tick-counting methods should be as rigorous as any other scientific procedure and described clearly enough to allow their use in other studies.
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.
In Search for Better Stink Bug Management, Scientists Look Up
A parasitoid wasp from Asia offers promise for biological control of the brown marmorated stink bug in North America, but new research suggests that monitoring efforts using primarily ground-level traps may be looking in the wrong place.
Testing Shows Dry, Red Sticky Traps Improve Spotted-Wing Drosophila Monitoring
A new study finds spotted-wing drosophila prefer red, glue-covered monitoring traps made of plastic rectangles or spheres compared to the most commonly used clear deli-cup traps. The findings will advance the pursuit of more efficient and effective monitoring techniques for the pest.
Study Shines a (Fluorescent) Light on Invasive Fruit Fly Trapping
To estimate the catch rate of traps for invasive spotted-wing drosophila fruit flies in tart cherry orchards, researchers at Michigan State University first marked thousands of flies with fluorescent dust and released them. Then they counted the recaptured flies under ultraviolet light.
The Collapsible Passive Trap: Mosquito Monitoring in a Lightweight Package
Evaluation of the collapsible passive trap for mosquitoes shows performs as well as other commonly used traps but in a lighter, easier-to-carry design, making it an attractive option for mosquito monitoring in remote areas.
Beware the “Dark Side” of Light Traps
Light traps are useful collecting devices to sample large numbers and species of insects, but they also may mask infestations of some insect-borne illnesses and even expose humans to disease vectors.
Building a Better Light Trap: Study Finds Specific Light Waves Attract Anopheline Mosquitoes
By Andrew Porterfield For more than 50 years, the light trap—an incandescent light source attached to an insect collector—has been the standard for sampling potentially disease-carrying mosquitos. The U.S. Centers […]
Line Trapping: A Promising Method for More Accurate Pest Monitoring
It’s easy to think of a pheromone trap as a lure, putting out a scent and waiting for insects to come rolling in. But insects aren’t sharks; they don’t sense […]
Why Stink Bug Pheromone Traps Perform Poorly During Winter Invasions
Score one for the brown marmorated stink bug, again. Since the pernicious pest arrived in the United States nearly 20 years ago, it has proven difficult to fend off, attacking […]
A Model for Effective, Reduced-Cost Bed Bug Monitoring
While the common bed bug (Cimex lectularius) can target all varieties of human habitats, it is a significant concern in settings such as multi-unit, low-income housing, especially those for the […]
