Temperature Extremes May Undermine Biocontrol of Emerald Ash Borer
Sudden cold waves may be lethal to overwintering larvae of two parasitoid wasp species used for biological control of emerald ash borer, while the borer larvae appear to more easily weather the extreme cold.
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.
How Drones Can Use Multispectral Imagery to Fight Pests
A new study shows how stress to soybean crops caused by the soybean aphid can be detected remotely by drone-based multispectral imagery.
Wild Pollinators Get the Job Done
Wild pollinators have the potential to play a bigger part in pollinating specialty crops, according to a new study.
Fungus Could Help Control Emerald Ash Borer
A recent study shows that male emerald ash borers infected with a deadly fungus readily transmit the fungus when mating, opening doors for future biological control efforts.
Spotted Lanternfly: Large Potential Range in U.S. and Beyond
A new study published today in the Journal of Economic Entomology models potential suitable habitat for the invasive spotted lanternfly and shows large swaths of the United States and beyond are likely to be vulnerable should the spotted lanternfly continue to spread.
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.
Did Two Florida Populations of Conehead Termites Arise From a Single Colonization Event?
Native to Central and South America, the conehead termite has been found in just two places in the United States: Dania Beach and Pompano Beach, Florida. A new genetic analysis of these two populations suggests they arose from a single invasion.
It’s a Bird! It’s a Plane! It’s an Ecological Field Study!
In a recent study in Germany, targeted delivery of insecticides by unmanned aerial vehicles was effective against oak processionary moths. Researchers say such drones are suitable for aerial spraying during field studies and may open new doors for "precision forestry."
Fatal Attraction: A Novel Solution to the Problem of Asian Citrus Psyllid on Residential Citrus
In many areas where the Asian citrus psyllid spreads citrus greening disease to commercial groves, it can evade control efforts by infesting residential citrus trees. A new attract-and-kill device, however, is being evaluated for managing psyllids on citrus in residential areas.
For Mass-Rearing Sterile Fruit Flies, Fewer Males Means More Efficient Mating
Sometimes, less is more. Case in point: the mass-rearing program that produces millions of sterile Mexican fruit flies (Anastrepha ludens) for managing wild populations. Scientists refining the effort find that a lower ratio of males to females in mating cages leads to higher fecundity and fertility in the females—and higher cost-effectiveness for the operation.
Wildflower Strips Bring Farmers Extra Money While Helping Native Bees
Planting strips of wildflowers next to crops is a boon for native bees, but few farms adopt the practice. A new study, however, shows farmers can turn an immediate profit by selling wildflower seeds retail, while the long-term benefits of increased pollination and crop yields materialize over time.
Pink Bollworm Versus Bt Cotton: Three Countries, Three Results
A new article in the Journal of Economic Entomology examines varying levels of resistance to Bt toxins developed by the pink bollworm in the United States, China, and India over the last 20 years, illustrating the importance of incorporating refuge crops in Bt systems.
A Promising New Parasitoid Drills Down on Emerald Ash Borers
In a recent study, the wasp Spathius galinae successfully established wild populations and outperformed other parasitoids in attacking invasive emerald ash borers in three northeastern states in the U.S. Researchers say it could become a useful biological control agent to protect native ash trees.
Building-Wide Pest Management Program Stops Cockroaches From Moving Nextdoor
A study of the spatial distribution of German cockroaches in a high-rise apartment building found infestations were clustered in groups of adjacent units. But a building-wide integrated pest management program can be successful in eliminating most infestations and, importantly, stopping the cockroaches from migrating from one apartment to the next.
Mandarin Boom Means Citrus Pest Management Must Evolve
The rise in popularity of mandarin oranges has outpaced knowledge of how integrated pest management (IPM) for them might differ from that of larger oranges. New research combines field study with years of data from citrus groves and shows that mandarins stand up surprisingly well to insect pests.
