Schistocerca cancellata locust - gregarious phase

Swarm Shift: How Locusts Switch Phases When Numbers Swell

After swarms of the South American locust Schistocerca cancellata reappeared in 2015 for the first time in 60 years, a study on what drives their swarm behavior finds the insects' population density acts as a trigger for a slew of biological and behavioral changes at the individual level.

mandarin oranges

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.

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.

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.

yellowjacket - Vespula squamosa

Yellowjackets: A Look at Opportunistic Raiders of Honey Bee Hives

Yellowjackets are nuisance predators of honey bees, preying on them and pillaging their honey. But bees fight back, and healthy hives are rarely at risk. Learn more about yellowjackets, their interactions with bees, and what sets yellowjackets apart from hornets and other fellow wasps.

Toxorhynchites rutilus mosquito larva feeding

Meet the Mosquito With a Big Appetite—for Other Mosquitoes

The mosquito species Toxorhynchites rutilus is harmless to humans but is a voracious predator of other mosquitoes. Researchers in Houston, Texas, are hoping the "mosquito assassin" could be put into action as a tool for controlling mosquitoes that carry human pathogens—if they can find an efficient way to raise the predator mosquitoes in the lab.

Pacific cicada killer - Sphecius convallis

When Cicada-Killer Wasps Become Cicada-Stealer Wasps

Hunting cicadas and lugging them back to a nest is hard work for a cicada-killer wasp. But sometimes all that hard work goes to waste, when a fellow wasp swoops in and lays her egg on the other wasp's prey. And that's if the cicada isn't stolen by a bird first.

khapra beetle - Trogoderma granarium

Khapra Beetle Can’t Beat the Heat

The khapra beetle does outsize damage to stored grains and is a top target at ports and border crossings. Researchers in Canada have found the threshold temperature that will kill the beetle at all life stages, even diapause.

insect sampling - bodycam evaluation 1

Bodycams Can Make for Better Agricultural Pest Management, Too

In a new study at the University of Arizona, researchers used body-mounted cameras to evaluate the efficiency of two insect pest sampling techniques—a sweepnet and a vacuum—in a cotton field. The perspective offered new insights into how such methods can be evaluated and could help growers and integrated pest management professionals further fine-tune their sampling techniques.
