Full Text: The stable fly can make cattle miserable, and producers have had only limited success in using traditional insecticides against the pest. Now researchers are identifying aromatic compounds that attract and repel stable flies and have used two compounds found in catnip to develop a control strategy.

In lab tests, the two compounds--ZE-nepetalactone and EZ-nepetalactone--discourage even starved stable flies from biting cattle and feeding on their blood, providing effective protection more than 98 percent of the time. The same compounds have a 95-percent success rate in discouraging female stable flies from laying their eggs. In addition, carbon dioxide and some compounds in manure and bacteria elicit antenna responses from stable flies that are similar to the flies' response to pheromones, which suggests that these compounds might be used as attractants for pest management.

These findings are important steps in developing biobased control tools and improving sustainable stable fly management. Junwei Zhu, USDA-ARS Agroecosystem Management Research Unit, Lincoln, NE 68583-0938; (402) 472-7525, jerry.zhu@ars.usda.gov.
