Survey underway for Phragmites scale in Louisiana

In Delta Farm Press

by Bruce Schultz

A team of 16 scientists and students led by the LSU AgCenter conducted a survey on May 31 to collect samples of a small insect that’s a potential threat to the fragile marsh of lower Plaquemines Parish, La.

The tiny insect, the Phragmites scale, is attacking Roseau cane, a plant similar to bamboo with a dense network of roots that hold marsh soil together. Continue reading

Urban warming slows photosynthesis and growth in city trees

by Matt Shipman, NC State University

New research from North Carolina State University finds that urban warming reduces growth and photosynthesis in city trees. The researchers found that insect pests are part of the problem, but that heat itself plays a more significant role.

Earlier studies have shown that urban warming increases pest abundance in street trees,” says Emily Meineke, lead author of a paper describing the work. “We wanted to know how urban warming and pest abundance affect tree growth, since trees pull carbon out of the atmosphere and convert it into biomass. This is important, because we know that high levels of atmospheric carbon play a role in climate change.” Meineke did the work while a Ph.D. student at NC State. She is now a postdoctoral researcher at Harvard. Continue reading

NC State doctoral student wins Friends of Southern IPM Award for work on urban heat islands

A doctoral student at NC State University will receive a regional award in November for his work on urban tree integrated pest management.

NCSU Ph.D. student, Adam Dale, was one of several graduate students nominated to receive a Friends of Southern IPM Graduate Student award. The Southern IPM Center, which sponsors the award, gives one Masters award and one Ph.D. award based on the decision of an outside panel.

Warmer temps limit impact of parasites, boost pest populations

By Matt Shipman

Climate change is expected to disrupt ecosystems by changing the life cycles of insects and other organisms in unpredictable ways – and scientists are getting a preview of these changes in cities. Research from North Carolina State University shows that some insect pests are thriving in warm, urban environments and developing earlier, limiting the impact of parasitoid wasps that normally help keep those pest populations in check.

Scale insects more abundant at higher temperatures

A study by two researchers at North Carolina State University concludes that damaging scale insects are more abundant in urban heat islands.
