Gut bacteria sheds light on honey bee health

In ARS News

by Kim Kaplan

Bacteria in the gut of young honey bees may provide clues about the impact parasites have on bee health. That and other experimental findings were published by U.S. Department of Agriculture‘sAgricultural Research Service (ARS) researchers in the Proceedings of the National Academy of Sciences.

Because young honey bees don’t have gut bacteria, entomologist Jay Evans and post-doc Ryan Schwarz at ARS’ Bee Research Laboratory in Beltsville, Maryland, and University of Texas at Austin professor Nancy Moran conducted tests to determine the impact different combinations of a common bacterium and a common parasite had on honey bee health. The scientists hypothesized that increasing the gut bacterium would make the bees more resistant to the parasite, but instead it lead to surprising results. Continue reading

Citrus trees in “old flush” need to be watched for Asian citrus psyllid

In ARS News

by Dennis O’Brien, Agricultural Research Service

A U.S. Department of Agriculture (USDA) entomologist is providing citrus growers with much-needed guidance about the best times to use insecticides to control Huanglongbing (HLB), or citrus greening.

HLB has cost Florida citrus growers an estimated $1.3 billion since 2005. The disease is caused by a bacterium spread by the Asian citrus psyllid, which feeds on leaves of infected trees and carries the disease from tree to tree. Insecticides are currently the best option for controlling HLB. Continue reading
