摘要
这项研究是在俄亥俄州伍斯特的俄亥俄州农业研究与发展中心的草坪上进行的。4月22日，对12.2 X 12.2 m的地块施用杀虫剂，地块布置在重复4次的RCB中。颗粒状杀虫剂使用滴滴喷雾器，液体喷雾器使用Teejet 8015喷嘴，压力为3.87 kg/cm2，体积为1384升/公顷。试验区不进行后处理灌溉。处理时环境条件为:billbugs:越冬成虫活跃;草皮:平整，干燥，高度6.35 cm, 75%肯塔基蓝草，15%高羊茅，10%阔叶草;茅草:没有;土壤:湿润，2.54厘米处58°F, 7.62厘米处55°F;天气:多云，57华氏度，5-16公里/小时;水:pH值6.75。7月在每个小区9.3 m2 (78 DAT)的中心采集的药效数据是根据每个小区8、10.8 cm直径样本的活billbug幼虫和蛹的数量。
Control of the Billbug Adults on A Lawn Area in Wayne County, 1992
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°F at 2.54 cm and 55°F at 7.62 cm; Weather: cloudy, 57°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.
