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.
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.
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 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.
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.
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.
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.
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.
In a new special collection on trap and cover crops in integrated pest management, experts review the latest research on various habitat-management methods and their applications in both deterring pest populations and fostering natural enemies of crop pests.
In a new model for integrated pest management, one cooperative extension pro says broader management, business, and sustainability factors must be factored in for IPM success.
Nonchemical Varroa-management methods are more common among small-scale beekeepers, but chemical varroacides show wide use among all types.
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.
A pilot program in a 150-acre zone in Miami in 2018 released as many as 375,000 Wolbachia-infected male Aedes aegypti mosquitoes per week for six months and succeeded in reducing the female Ae. aegypti population by more than 75 percent.
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.
A new study examines two host-targeted tick-control methods, and one shows a distinct advantage, but it's likely not cost-effective for the typical homeowner.
Meet Alejandro Del Pozo-Valdivia, Ph.D., IPM entomology advisor at the University of California Cooperative Extension, connector of grower and research communities, and subject of the next installment of our "Standout Early Career Professionals" series.
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.
