Clover Root Curculio: Historic Perspectives Guide Modern Management
Understudied and less well-known than other pests, the clover root curculio damages clover and alfalfa crops across North America. A new profile of the pest and options for managing it is published this month in the open-access Journal of Integrated Pest Management.
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.
The Eyes Have It: How Butterflies Navigate to Suitable Habitat
Do butterflies find suitable habitat through vision or via other senses? The results of a new study were easy to see: Butterflies with flash-induced blindness consistently failed to navigate to target habitat that unaffected butterflies could readily find.
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.
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.
When Forest Fires Flare, Woodboring Beetles Rush In
Woodboring beetles make good food for woodpeckers, and researchers studying how forest fires affect bird populations have studied the patterns of woodboring-beetle colonization of forests after fires. Their findings offer clues and raise new questions about the impact of fires on forest ecosystems, in a time of increased fire activity and longer fire seasons.
Research That’s For the Birds: Grazed Land Increases Insect Food Supply for Sage Grouse
A recent Environmental Entomology study sheds new light on how insects fit into the puzzle of sage grouse—and rangeland—conservation.
European Earwig: Fruit Pest, Potential Ally, or Both?
A new profile in the Journal of Integrated Pest Management busts some myths about the European earwig (Forficula auricularia). Though perceived as a pest, it is actually an underappreciated biological control agent and likely a beneficial insect in most apple orchards.
Drosophilid Melting Pot: African Fig Fly Meets Spotted-Wing Drosophila in the U.S.
The African fig fly (Zaprionus indianus) is an invasive fruit fly in North America that has been found commingling with its cousin spotted-wing drosophila (Drosophila suzukii), sometimes even using the latter's egg-laying sites for its own. A new profile in the Journal of Integrated Pest Management highlights the African fig fly's biology and range and offers options for management.
Researchers Share New Method for Detecting Insect Egg Predators
A proof-of-concept study shows insect eggs can be marked with protein that can be later detected in a gut-content analysis of arthropod predators that fed on the eggs. Researchers say the method has applications in biological control and beyond.
Virus Helps Onion Thrips Live Longer, Do More Damage
Iris yellow spot virus is bad for onions, but it's good for the thrips species that carry the virus and spread it to onion plants. In a recent study, infected onion thrips lived about 20 percent longer than uninfected thrips, giving them more time to damage onion plants and transmit the virus.
How a Honey Bee’s Waggle is Inspiring Aerospace Design
Engineers may recognize the internal muscle structure of a honey bee abdomen for its resemblance to a Stewart platform, a mechanical device that enables six degrees of freedom in movement. Researchers who have found its natural equivalent in bees say the discovery is already informing their work in designing articulating nose cones for rockets.
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.
New Guide Details Pest-Management Practices for Longan
A major fruit export from Vietnam, longan has been well studied in Southeast Asia, but a new profile in the open-access Journal of Integrated Pest Management offers a compilation of longan IPM research for potentially new audiences.
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.
Spectroscopy Opens Potential for Ultra-Early Pest Detection in Crops
Researchers at Purdue University are developing new ways to apply spectroscopy in service of greater food security. By analyzing light reflected by plants, they can detect compounds the plants produce soon after they face an insect pest attack or other stressor.
