Stink Bug Rearing Technique Could Lead to Control Strategies

bmsb1-eggs-nymphs

Researchers at North Carolina A&T State University have found a successful rearing method for brown marmorated stink bugs (Halyomorpha halys), which could be used to develop a reliable supply of the bugs for research. Drs. Beatrice Dingha and Louis Jackai have developed a laboratory rearing method that has successfully produced five generations of brown marmorated […]

New Zealand Farmers use Moths and Beetles to Fight Weeds

ragwort

The Horizons Regional Council, a government agency in New Zealand, has recently described a successful example of biological control, which involves the reduction of a pest by using a natural enemy instead of pesticides. A weed called ragwort (Senecio jacobaeae) competes with plants in pastures and contains alkaloids that are toxic to livestock. In order […]

Earwig Nymphs Share Food with their Brothers and Sisters

earwig

Competition among animals can be fierce, even among brothers and sisters. Some caterpillars, for example, will eat their siblings, and baby birds sometimes push their brothers and sisters out of the nest. However, new research shows that this isn’t the case with earwigs. “Young earwig offspring don’t simply compete for food. Rather the siblings share […]

Cataloging Insect and Bat Diversity: A Research Trip to Belize

wasp-mimicing-moth-wp

By David Wyatt It was late 2002 and I had just received my latest Bat Conservation International magazine. As I relaxed on the couch and read the articles, my eye caught on a field expedition to Belize being led by biologist Fiona Reid. This expedition would study the bats of Belize at several locations in […]

Pheromone Research May Lead to New Insect Control Methods

fireant

Each year in the United States, fire ants cost $7 billion for control, damage repair, and medical care. They infest millions of acres in urban, agricultural, wildlife, recreational and industrial areas. In order to combat the the red imported fire ant, scientists at the USDA’s Agricultural Research Service are studying pheromones that are secreted by […]

Carnivorous Caterpillars Fool Ants by Sounding like Queens

carnivorous-caterpillar

Last week Kiran Gadhave wrote about “The Curious Case of the Large Blue Butterfly,” and he described how the butterfly larvae fool ants into taking them into their colonies, where they then eat the ant grubs. Now researchers may have discovered how the caterpillars fool the ants by making sounds that mimic the ant queen. […]

Entomologists Use Dogs to Hunt Down Stink Bugs

Last year at Entomology 2013, the 60th Annual Meeting of the Entomological Society of America, scientists from the U.S. Department of Agriculture gave a presentation called “Exploring Overwintering Ecology of Brown Marmorated Stink Bug Using Detector Dogs.” Now they have published an article about this topic in the journal PLOS ONE. The brown marmorated stink […]

The Florida Entomological Society (FES) has announced that it will co-locate its 2016 annual meeting with the XXV International Congress of Entomology (ICE), which will be held in Orlando, FL from September 25-30, 2016. Like the Olympics, the International Congress of Entomology is held every four years, and it attracts thousands of participants from all […]

The First Journal Article on Insecticide Resistance was Published 100 Years Ago this Month

scale-insect

One hundred years ago this month, an entomologist at the Washington Agricultural Experiment Station named A. L. Melander published an article in the Journal of Economic Entomology called “Can Insects Become Resistant to Sprays?” It is widely regarded as the first ever published article on arthropod resistance to insecticides. “Melander’s 1914 paper not only reported […]

Termites Tunnel and Transport Food Faster at Higher Temperatures

Coptotermes-formosanus

Entomologists at the University of Florida recently published an article in the Annals of the Entomological Society of America that may help to explain the seasonal activities of termites. The effects of temperature on tunneling and food-transportation activity of four subterranean termite species — Coptotermes formosanus Shiraki, Coptotermes gestroi (Wasmann), Reticulitermes virginicus (Banks), and Reticulitermes […]
