UGA researcher targets prionus root borers
“The utility of the traps as a monitoring tool is a great improvement over the old light trap method that has been used for the past 30 years,” said Dutcher, who noted that the traps may also be effective as a part of an integrated beetle control method.
Two possible methods are mating disruption where an orchard is inundated with pheromone and males cannot find mates, or mass trapping where male beetles are trapped over a large plot of acreage with a matrix of evenly spaced traps.
Dutcher and his team of pecan growers are also testing chemical control methods where beetles are monitored with traps and the soil is treated to control the beetles before they lay eggs near the tree trunk and roots. Research is under way to incorporate the new trapping system into pecan pest management in Georgia pecans.
Pecan orchards with high root borer infestations have been reported across south Georgia from Cordele to Leesburg and from Tifton to Waycross.
