Yellow pyramid traps baited
with Euschistus spp. pheromone may replace limb jarring for monitoring
brown stink bugs in peach. In 2001, an insect pest management program was
demonstrated in four Arkansas peach orchards. Four yellow pyramid traps were
placed individually under peach trees at 30m intervals in the wooded perimeter
of each orchard. Weekly or biweekly, rubber septum each charged with 50ul
methyl 2,4-decadiendate replaced, and the numbers of brown stink bugs per trap
and per limb jarring were recorded. Brown stink bug population levels in peach
trees exceeded the threshold of 1 stink bug per limb jarring only on 19 April,
9 and 19 June and insecticide applications were recommended to growers. The
corresponding weekly counts from the yellow pyramid traps were > 60 stink
bugs. The trap to limb jarring ratio of the number of stink bugs was 60:1. The
tentative trap economic threshold to be tested in 2002 will be 60 brown stink
bugs per pyramid trap per week.
