Essential oils extracted from leaves of Aloysia polystachya and A. citriodora (Verbenaceae) and from leaves and fruits of Schinus molle var. areira (Anacardiaceae) were tested for their repellent and toxic activities against adults of Rhizopertha dominica (Coleoptera: Bostrichidae). Topical application and filter paper assays were employed for contact toxicity studies; filter paper impregnation was also used for fumigant and repellent assays. In topical tests A. polystachya was as effective as S. molle leaves. In the case of repellent assays, A. citriodora was the most effective oil based on the class scale. A. polystachya was the most toxic plant on contact toxicity by filter paper assay (LC50 26.6 mg/cm2). Fumigant toxicity was only evaluated with fruits and leaves of S. molle, and no significant differences were found between them. Published data are included to compare the fumigant toxicity of S. molle with that of A. citridora and A. polystachya.
对从多穗香茶菜（唇形科）和柠檬香茶菜（唇形科）叶片以及秘鲁胡椒树（漆树科）叶片和果实中提取的精油进行了测试，以研究其对谷蠹成虫（鞘翅目：长蠹科）的驱避和毒性活性。采用局部涂抹法和滤纸法进行接触毒性研究；滤纸浸渍法也用于熏蒸和驱避试验。在局部试验中，多穗香茶菜与秘鲁胡椒树叶片的效果相当。在驱避试验中，根据等级量表，柠檬香茶菜是最有效的精油。通过滤纸法进行接触毒性测试时，多穗香茶菜是毒性最强的植物（LC50为26.6毫克/平方厘米）。仅对秘鲁胡椒树的果实和叶片进行了熏蒸毒性评估，二者之间未发现显著差异。纳入已发表的数据以比较秘鲁胡椒树与柠檬香茶菜和多穗香茶菜的熏蒸毒性。
