A filter paper bioassay was developed for testing the efficacy of nematodes and other agents for control of Diaprepes abbreviatus larvae. Surfactants, with and without Steinernema riobravis, were screened first in the filter paper bioassay and then in a potted citrus seedling study. The results of the two assays were in agreement on the relative merits of the compounds tested. Surfactants increased larval mortality at 4 days for the filter paper bioassay and 1 week for the potted plant bioassay. At 8 days for the filter paper bioassay and 2 weeks for the potted plant bioassay, nematodes alone were equal to treatments of nematodes plus surfactants.
开发了一种滤纸生物测定法，用于测试线虫和其他药剂防治短体蔗根象幼虫的效果。首先在滤纸生物测定法中筛选了添加和未添加里奥布拉夫斯小杆线虫（Steinernema riobravis）的表面活性剂，然后在盆栽柑橘幼苗试验中进行筛选。两种测定法的结果在受试化合物的相对优点方面是一致的。表面活性剂在滤纸生物测定法的第4天和盆栽植物生物测定法的第1周提高了幼虫死亡率。在滤纸生物测定法的第8天和盆栽植物生物测定法的第2周，单独使用线虫与线虫加表面活性剂的处理效果相当。
