| Abstract/Contents: | "The study was located on lawns of the Ohio Agricultural Research and Development Center at Wooster, Ohio. Insecticides were applied 22 Apr to plots 12.2 X 12.2 m arranged in RCB replicated 4 times. Granular insecticides were applied using a drop spreader and liquids using a CO2 sprayer with Teejet 8015 nozzles at 3.87 kg/cm2 pressure that delivered a volume of 1384 liter/ha. The experimental area received no posttreatment irrigation. Environmental conditions at time of treatment were: billbugs: overwintered adults active; turf: level, dry, 6.35 cm height, 75% Kentucky bluegrass, 15% Tall fescue, 10% broadleaf weeds; thatch: none; soil: moist, 58 degreesF at 2.54 cm and 55 degrees F at 7.62 cm; Weather: cloudy 57 degrees F, 5-16 km/h; water: pH 6.75. Efficacy data taken from the center 9.3 m2 of each plot Jul (78 DAT) were based on the number of live billbug larvae and pupae in 8, 10.8 cm diam samples from each plot. Adult data from pitfall traps located in the center 9.3 m2 taken weekly from two wk pretreatment to 26 wk posttreatment failted to show control. This is viewed as a function of the adults mobility. Population of adults in pitfall traps was 98% S. parvulus and 2% S. minimus. Larval data indicates all treatments provided significant control of billbugs. Another study conducted nearby using smaller plots (6.1 X 6.1 m) failed to demonstrate adult control by way of larval counts. Authors perceive this as an effect of an inadequate plot size due to the mobility of this insect. No phytotoxicity was observed." |
