  • Japanese beetles thrive in human landscapes

    Jul 18, 2011 8:00 am

    According to INHS entomologist Chris Dietrich, Japanese beetles are generalists and will eat approximately 300 different types of plants, which is not unusual for an introduced species. Human lawns make perfect habitat for the grubs which feed on the roots of grass, but killing the grubs will do little, as adults will fly in from other yards.

  • Corn rootworm on the rebound?

    Jul 18, 2011 9:00 am

    After a couple of years with low levels of damage from Western Corn Rootworms, INHS Insect Behaviorist Joe Spencer and his colleagues have found significant damage to roots and a higher level of adult emergence compared to last year. For more information, visit Farms.com.

  • Western corn rootworm developing resistance to rotation

    Sep 4, 2013 8:30 am

    INHS Behavioral Entomologist Joe Spencer is looking at rotation-resistant western corn rootworms, which are causing severe injury to crops. Crops modified to resist infestation by insects and crop rotation are some of the methods to control injurious insects, but some rootworms have developed resistance to these mechanisms. Repeated use of the modified corn year after year has given the rootworms time to adapt. Producers are encouraged to watch their fields for injury. This story was reported in InvestorPlace and the Bulletin.

  • Soybean Aphids have lowest impact in years

    Sep 25, 2012 8:00 am

  • Engineering students help INHS researchers

    Aug 6, 2012 8:00 am

    INHS researchers tapped into the innovative nature of engineering students to design systems that would help address questions about North American River Otters. As part of their senior design projects, 4 groups of students set out to tackle different problems. One device, the Otter Print Shooter, is a pressure and motion sensitive camera encased in clear box, under ground. When an otter steps on the box, the print shooter takes a photo of the paw. Otter paw prints are believed to have unique patterns, similar to fingerprints. The Otter Stalker System wirelessly connects multiple trail cameras, thereby increasing the field of view, allowing the researchers to capture more of the behavior of river otters.

  • Is there enough food in the Great Lakes to support Asian Carp?

    Nov 3, 2010 9:00 am

    In a press release issued by Illinois Indiana SeaGrant, INHS Aquatic Ecologists Walter Hill and Sandra Cooke suggest that due to other invasive species in the Great Lakes, Asian Carp may not find enough food to thrive. However, Hill does not see their results as a reason to relent on efforts to keep Asian carp out of the Great Lakes. "Given the potential consequences to Great Lakes ecosystems if these filter feeders do prove capable of establishing reproducing populations, efforts to keep Asian carp out of the Great Lakes must not be lessened." Another story discusses some of the methods being used to keep Asian Carp out of the Great Lakes, including an experiment being led by Blake Ruebush and Greg Sass on a Sound-Bubble-Strobe-Light-Barrier.

  • Waterfowl counts higher than average
