Abstract

Survival ofReticulitermes hesperus workers was assessed inPseudotsuga menziesii, Lysiloma seemanii, andTabebuia ochracea sawdusts; and on heartwood solvent extracts ofP. menziesii, L. seemanii, T. ochracea, Pinus ponderosa, Tabebuia guayacan, and aCentrolobium species. Survival inP. menziesii sawdust was 100% at 5 days and 81-87% at 15 days. Survival inL. seemanii andT. ochracea sawdusts was significantly less over both 5 and 15 days than in the starvation control, indicating toxicity. Survival on filter papers treated with solvent extracts ofT. ochracea andP. ponderosa was significantly less than that on control papers, but onlyP. ponderosa differed significantly from the starvation control. In behavioral assays with groups and with individualR. hesperus workers, extracts ofP. menziesii andP. ponderosa were preferred. In the individual behavioral assays, extracts ofT. guayacan andT. ochracea were repellent. Results of toxicity assays were not predictable from preference assays.

摘要

在辐射松、黄杉和黄檀刨花中评估了美洲散白蚁工蚁的存活率；并在辐射松、黄杉、黄檀、西洋杉、圭亚那苦木和某种黄檀的心材溶剂提取物上评估了存活率。在 5 天和 15 天的时间里，在辐射松刨花中的存活率均为 100%，在黄杉和黄檀刨花中的存活率显著低于饥饿对照，表明毒性。用黄檀和西洋杉溶剂提取物处理的滤纸的存活率明显低于对照滤纸，但只有西洋杉与饥饿对照有显著差异。在有群体和个体美洲散白蚁工蚁的行为测定中，对辐射松和西洋杉的提取物表现出偏好。在个体行为测定中，对苦木和黄檀的提取物表现出驱避性。毒性测定的结果不能从偏好测定中预测。
