The peachtree borer,
Synanthedon exitiosa
, and lesser peachtree borer,
S. pictipes
, are economically important indirect pests of peach in West Virginia. The purpose of this 3-year study was to compare the efficacy of mating disruption and post-harvest trunk sprays of chlorpyrifos insecticide for control of this pest complex in a commercial peach orchard. Overall, Isomate
PTB
-Dual disruption dispensers applied at a rate of 371/ha significantly disrupted the male mate-finding behavior of
S. exitiosa
and
S. pictipes
. In addition, the
infestation
of peach trees by
S. exitiosa
larvae did not vary significantly between mating disruption and insecticide treated plots. Hot-spot maps of
S. exitiosa
infestation
showed significant spatial clusters of
infestation
predominately near the perimeter of all orchard plots, or where trees were missing within and/or between rows. The generation of standard deviational ellipses revelated that the location of
S. exitiosa
infestations in orchard plots remained relatively constant between years, and were generally oriented in a north and easterly direction, which coincided with the prevailing wind direction. Although our data indicated that mating disruption can provide growers with an effective non-chemical alternative to chlorpyrifos trunk sprays, several variables may affect its long-term success in West Virginia peach orchards; most notably the presence of high population densities, problems with maintaining adequate pheromone coverage, and the need for area-wide implementation.
