Potato psyllid 

Dr. Casey D. Butler recently received his PhD from the University of California-Riverside (UCR) and earned his BS (’03) and MS (’06) degrees from Purdue University. At UCR, Casey’s research focused on the development of management strategies for the potato psyllid, Bactericera cockerelli (Sulc), in southern California, a major pest of solanaceous crops. The goal of his research is to build the foundation of integrated pest management against this pest by first developing sampling plans in agricultural fields and then move toward more targeted chemical tools, biological control, and host plant resistance. His research regarding host plant resistance involved collaborators at the USDA-ARS and Texas A&M University. Twenty-two potato genotypes were tested on adult potato psyllids for possible antizenosis to determine if specific breeding clones or varieties can decrease transmission of Ca. L. psyllaurous. Five of the potato genotypes significantly decreased transmission compared to controls. The next step is to test these promising genotypes in the field before recommendations can be made for the most effective integration with a management program. Casey is a R&D scientist at Syngenta Crop Protection, Inc.

He said: This is a special honor and I am extremely grateful for receiving the Kenneth and Barbara Starks Plant Resistance to Insects Graduate Student Research Award. Being acknowledged with this award has further encouraged my interest in host plant resistance to insects in agricultire.

Kevin Steffey (BS ’72) was one of ten ECB team members and eight associate team members awarded the Integrative Pest Management Team Award (sponsored by Dow AgroSciences).

The European Corn Borer Team documented a 6.9 billion dollar cumulative benefit to U.S. corn producers resulting from 14 years of area-wide suppression of the pest Ostrinia nubilalis (Hubner) following the adoption of transgenic corn, specifically corn hybrids expressing one or more insecticidal proteins of the bacterium Bacillus thuringiensis. The team found a significant decline in ECB larval and moth populations for five major corn-growing states in the central U.S. Corn Belt. The team had access to, or collected, long-term (50+ years) larval and moth population data that allowed a quantitative analysis of population change before and after the introduction of Bt corn. In brief, the area-wide suppression occurs over time because Bt corn, as a form of host plant resistance, continues to be highly effective, providing virtually 100% control of the pest with no field-evolved resistance to Bt. The analysis confirmed that in addition to the direct benefits to Bt corn producers, nearly 63% of the savings ($4.9 billion) actually accrued to non-Bt corn growers. The team’s findings were reported by Science, NPR, the Associated Press, German Public Radio, and other news outlets.

Fighting Ants Fodder for Writers

Ants, it seems, relish a good fight. If you take a moment to observe ants in nature, you will notice that battles between different species of ants are a common occurrence. Such hostile encounters within the ant world have inspired many a writer to take up pen and ink, or in modern times keyboard and screen, to capture the moment.

While he lived at Walden Pond, Henry David Thoreau witnessed ants in the woodpile engaged in less-than-friendly activities. Based on his observations, he wrote "The Battle of the Ants," an excerpt from "Walden." In his essay, Thoreau described the ants as "the red republicans on the one hand, and the black imperialists on the other." Thoreau was amazed at the tenacity of the battling ants and wrote, "It was evident that their battle-cry was 'Conquer or die.'"

Arwin Provonsha amid the vast Entomology Department insect collection 

The Purdue Entomological Research Collection (PERC), whose specimens date back to the beginnings of the University, contains the largest, most complete insect reference collection in Indiana. It's basically a library of bugs. From the exotic (consider the Madagascar hissing cockroach) to the invasive (an Oriental beetle now represents a serious threat to Indiana plants), PERC offers more than 2 million insects representing more than 150,000 species. And they add approximately 15,000 new specimens each year.

Arwin Provonsha, the curator and scientific illustrator, though partially retired, maintains a full-time passion for insects. He's drawn thousands of them, illustrating a dozen books, and, since starting in 1971, he's been the point man for identifying and tagging the creatures as they've passed through PERC.

Hermetic bags save African crop, but not how experts once thought

The hermetic grain storage bags that cut off oxygen to weevils and have saved West and Central African farmers hundreds of millions of dollars by putting the brakes on the insects' rapid multiplication don't merely suffocate them as once thought, a Purdue University study shows.

More than 25 years after introducing the Purdue Improved Cowpea Storage (PICS) bags to farmers in Africa, Larry Murdock, a professor of insect physiology, discovered that weevils produce much of their water themselves through metabolic processes. When oxygen in the bags decreases, the weevils cannot use it to create water, and instead of suffocating, they eventually die of thirst.

Crop pests may be more abundant in Indiana farm fields this spring because of what continues to be a mild winter.

Some species of insects and weeds may have benefited from the warmer-than-normal temperatures and lack of snowfall in the state, two Purdue Extension specialists say.

Tamarisk manna scale (manna) 

There are many types of scales. Some are small plate-like structures that form the external covering of fish or reptiles. There are flakey scales, such as the rust that forms on metal. A system of ordered marks, such as a ruler with inches and centimeters, used for measurements is also called a scale. Another type of scale is a series of tones in music. Other scales, such as the one in your bathroom, are designed for weighing things.

There are also scales in the world of insects - a fact that almost anyone who raises plants for either fun or profit can attest. That's because scales of the insect kind are major plant pests.

Val J. Watts and Catherine A. Hill, Purdue researchers, prepare a test on insect larvae 

Purdue researchers are discovering the next generation of insecticides directed at disease-carrying insects like mosquitoes, ticks and tsetse flies, which could help professionals in the human health, veterinary and crop production sectors.

Catherine A. Hill, associate professor of entomology in the College of Agriculture, and Val J. Watts, professor of medicinal chemistry and molecular pharmacology in the College of Pharmacy, say vector insects - which carry and transmit infectious pathogens or parasites to other living organisms - are developing resistance to insecticides sprayed in the air or embedded in bed nets. The increased resistance makes insecticides less effective.

Robber fly eating Japanese beetle on a green leaf 

Human history has had its share of infamous robbers. In the United States, Jesse James, Bonnie and Clyde, and John Dillinger come to mind. England was home to Robin Hood and Dick Turpin; individuals who it is said sometimes helped themselves to the money of others.

In the interest of full disclosure, to my knowledge, the English outlaw Dick Turpin is not one of my ancestors. While being related to a legendary robber might not seem to be a good thing, in this case, it does have its perks. People with the surname Turpin are sometimes given a free drink at Dick Turpin British pubs!

Almost everyone has read or heard a story that begins with, "Once upon a time." That phrase is often used to introduce a fable or a tale with its origins in bygone days. For example, "The Story of the Three Bears" begins, "Once upon a time, there was a little girl named Goldilocks."

Once upon a time in the Midwestern United States there existed a major ecosystem - the tallgrass prairie. It covered some 142 million acres from western Indiana through Illinois and Iowa to the eastern parts of Nebraska and Kansas.

Honey bee on large leaf 

Honeybee populations have been in serious decline for years, and Purdue University scientists may have identified one of the factors that cause bee deaths around agricultural fields.

Analyses of bees found dead in and around hives from several apiaries over two years in Indiana showed the presence of neonicotinoid insecticides, which are commonly used to coat corn and soybean seeds before planting. The research showed that those insecticides were present at high concentrations in waste talc that is exhausted from farm machinery during planting.
