This summer saw some extensive billbug damage in many parts of Indiana.  Obvious damage to Kentucky bluegrass in the central and northern parts of the state are not uncommon and can usually be attributed to the bluegrass billbug.  However, reports...

We have been monitoring reports of very large infestations of armyworm moths flying into Kentucky this spring.  Armyworms move north with storms from the southern states each year and depending upon how and where the storms blow will dictate when...

It seems that the Japanese beetles have been arriving early for the last few years but this year is truly an exception. The first Japanese beetles of the year were observed in central Indiana on the 3rd of June. This...

It appears that our unseasonably warm spring has pushed the activity of many insects as much as 2-3 weeks ahead of traditional expectations. Among the turfgrass insects that are showing up early this year are the billbugs. These insects over-winter...

It was just a matter of time. While invasive species such as the emerald ash borer have been garnering so much attention in the press, the Turfgrass Entomology and Applied Ecology Laboratory at Purdue University has been tracking the spread...

Earthworm activity is on the rise as soils warm up, but their mounds will be highly visible until grass starts growing in late March and April. Earthworms are highly beneficial because they create channels for air and water penetration, reduce...

The first Japanese beetles of the year were observed in central Indiana last week and now is a great time to review the biology and control of these pests. Japanese beetle adults pupate from larvae in late spring and begin...

As our nematode survey continues, more questions are being asked about nematodes, their damage potential, etc. Following is an update on the survey:  Do not attribute all vague symptoms to nematodes. Nematode populations and symptoms are extremely complex and...

Recent storms have generated the weather patterns that bring black cutworm moths into our state each year. Pheromone traps picked up the first black cutworm moths of the season during the past two weeks. Predictive models estimate that the first...

The first Japanese beetles of the year were observed in central Indiana on June 22 and have since come out in full force. They are being reported in large numbers from many places throughout the state feeding on their favorite...

Significant weather events from the south usually are responsible for the movement of the black cutworm moths into our area each spring beginning as early as March. Black light traps stationed throughout the state have failed to catch many black...

Japanese beetles are back! They appeared 10 days to 2 weeks earlier than normal this year and indications are pointing to a very heavy population in many parts of the state. Last years weather conditions kept soils moist which apparently...
