Weekly Insect Bytes for June 27
June 27, 2014
We are collecting brown marmorated stink bug adults and nymphs (first week of capturing nymphs) in traps located in fruit orchards and baited with a combination of BMSB aggregation pheromone. Also, earlier this past week we received a notice from the Pennsylvania Department of Agriculture confirming the EPA approval for Section 18 Emergency Registration for PA of bifenthrin (pyrethroid, IRAC Group 3A). Japanese beetles are present in orchards located in southern Pennsylvania.
