Abstract:The bluegrass billbug, Sphenophorus paroulus Gyllenhal was a serious pest of home lawns for the 2nd successive season in isolated suburban areas of Rochester, N. Y. Overwintering adults were active by mid-May 1968, but populations high enough to produce damage were not present until the 1st week in July. Where 50 adults could be collected from paved streets, driveways, and sidewalks in 5 minutes, untreated lawns were subsequently completely destroyed.
Insecticides, their formulations, and doses in ounces (oz) active ingredient per 1000 ft3 that produced 87+% control and prevented lawn damage included Baygon® (o-isopropoxyphenyl methylcarbamate)50wp and 5G at 30z, diazinon 2G and 14G at 3 oz, and carbaryl 80 wp at 6.4 oz.
In laboratory tests, diazinon was the most effective insecticide, producing the highest mortality of larvae and adults infesting treated soil and adults feeding on treated grass stems. Results of field insecticide studies supplemented by laboratory tests points toward the evidence that adults were killed before ovipositing, resulting in protection of lawns from billbug injury.
