摘要:

本研究旨在挖掘仓储害虫的新型植物源药剂,并有效开发利用毒草——瑞香狼毒。以新鲜瑞香狼毒不同器官与提取物为试材,采用熏蒸与趋避方法,对3种常见仓储害虫进行测试。结果发现,瑞香狼毒在常规几种提取液中,石油醚提取物活性最强。瑞香狼毒花、叶、根、地上部分、茎石油醚提取物对杂拟谷盗的致死中浓度分别是:9.80、19.59、29.89、39.94、51.32 mg/L;瑞香狼毒花的石油醚提取物对杂拟谷盗、赤拟谷盗、米象的致死中浓度分别为:9.80、14.47、18.66 mg/L。杂拟谷盗趋向于瑞香狼毒及其提取物,米象对其具有趋避性。瑞香狼毒花石油醚提取物可以作为仓储害虫的植物源药剂开发利用。

Abstract:

In order to excavate a new plant-derived medicament for storage pests and effectively develop and utilize Stellera chamaejasme L., a poisonous weed, using different organs and extracts of Stellera chamaejasme L. as test materials, three common storage pests were tested by fumigation and avoidance methods. Among several conventional extracts of Stellera chamaejasme L., petroleum ether extract had the strongest activity. The lethal concentrations of petroleum ether extracts from flowers, leaves, roots, aerial parts and stems were 9.80 mg/L, 19.59 mg/L, 29.89 mg/L, 39.94 mg/L and 51.32 mg/L respectively; the lethal concentrations of petroleum ether extract from Stellera chamaejasme L. to Tribolium confusum (H.), Tribolium castaneum (Herbst) and Sitophilus oryzae (L.) were 9.80 mg/L, 14.47 mg/L and 18.66 mg/L, respectively. Tribolium confusum (H.) tends to be Stellera chamaejasme L and its extract, and Tribolium castaneum (Herbst) is repellent to it. The petroleum ether extract of Stellera chamaejasme can be used as a botanical drug for storage pests.
