Research in the Sierra Nevada region of California illustrates the varying flower choices of bumble bees: The five most common bumble bee species studied each selected a different assortment of flowers, and each selected at least one flower species not selected by the others. The findings are already being put to use in forest restoration efforts to increase and improve quality of bumble bee habitat.
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.
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.
Pest management is more than just matching pests with control methods. A tangled web of societal influences also play a role in growers' decisions and their uptake of integrated pest management, and researchers say the science of "social ecological systems" can inform efforts to increase IPM adoption.
Bumble bee nests can be hard to find and study, so researchers hope they can create artificial nest boxes for them to use and be observed more easily. But will bumble bees use such boxes? New research offers some clues about optimal design and placement of bumble bee "domiciles."
When their ranges overlap, two invasive mosquito species mate but produce no offspring, in an event known as satyrization. They can evolve quickly to learn to avoid each other, but that choosiness may cost the mosquitoes in other ways.
Research in Pennsylvania shows that overall colony weight and the number of worker bees to be the leading factors in determining overwintering survival of honey bee (Apis mellifera) colonies. For colonies in which the combined weight of adult bees, brood, and food stores exceeded 30 kilograms, overwinter survival rates were about 94 percent.
A new study shows that growing a variety of crops in the same field increases local insect diversity and even improves the ratio of natural-enemy insects to pest insects.
Learning how cuckoo bumble bees cheat the eusocial system can tell scientists a lot about how insect sociality evolves and how hosts and parasites coevolve. But, as other bees face declines, cuckoo bees will only get more difficult to study.
A new study that explores the effect of smoke on honey bee (Apis mellifera) behavior finds that it reduces the instance of bees releasing a venom droplet in their signaling of danger to other bees, which researchers speculate may thereby reduce the amount of alarm pheromone released.
In the course of a study on mosquito movement, researchers discovered that local colonies of honey bees had foraged on a nontoxic sugar bait meant for the mosquitoes. The bait was dyed red to track mosquitoes that fed on it, but the dye also showed up in much of the bees' honey.
New research shows that late-stage Anopheles gambiae larvae will eat eggs and first-instar larvae of their own species, calling into question the common view that females of the mosquito species avoid laying eggs in water where other larvae are already present.
First encountered in the United States in Pennsylvania in 2014, the spotted lanternfly had spread to New York, Delaware, and Virginia by early 2018. The invasive insect threatens Tree of Heaven as well as grapes, hops, and fruit trees, and it has a penchant for hitchhiking. Anyone sighting spotted lanternfly is urged to report it to their state agriculture department or local extension office.
Grape root borers are slow killers of grape vines, but also are hard to detect.
School nurses deal directly with the effects of lice, ticks, and mosquitoes on students and can be an important addition to the IPM team.
Highlighted Posters at Entomology 2017 were selected by the Program Committee to exemplify the meeting theme of "ignite. inspire. innovate."
While a greenhouse structure affords growers pest control options that are not available for field crops, such as physical exclusion, it can also create challenges.
