摘　　要：选用７种植物提取物，分别设置８００ｐｐｍ、４００ｐｐｍ、２００ｐｐｍ、１００ｐｐｍ、５０ｐｐｍ ５个浓度梯度，对赤拟谷盗进行试验。结果表明，对赤拟谷盗种群形成抑制效果最好的 是 ８００ｐｐｍ的桔皮提取物，抑制率为 ９３．４％；其次是 ８００ｐｐｍ的脐橙提取物，抑制率为 ８５．７％。８００ｐｐｍ的一年蓬花瓣、肉桂、艾蒿、山萘、鱼腥草提取物对赤拟谷盗种群形成抑 制率依次为７８．１％、７６．４％、７４．４％、６７．８％、５４．３％。在同种植物提取物的５个浓度梯 度中，以最高浓度８００ｐｐｍ的抑制效果最好。在试验剂量范围内，桔皮、脐橙、肉桂、山 萘、艾蒿、鱼腥草的提取物对赤拟谷盗成虫和幼虫都有不同程度的驱避作用。７种植物 提取物对赤拟谷盗成虫和幼虫均未表现明显的触杀作用。The extract (concentration 800, 400, 200, 100 and 50ppm) of 7 plants was tested to control Tribolium castaneum. The result showed that 800ppm of orange skin extract had the best inhibition (93. 4%). following 800ppm Umbilical orange skin extract (85. 7%). Inhibition of 800ppm Erigeron annuus. Cinnamonum cassia. Artemisia argyi. Kaempferia galanga. Cordate houttuynia on Tribolium castaneum spicies was 78.1, 76.4 , 74. 4. 67. 8 and 54. 3% respectively. The highes concentration (800ppm) in 5 concentrations for the same plant had the best inhibition effect. In the test dosages, the extract of orange skin, Umbilical orange skin, Cinmamomum cassia. Kaempferia galangn. Artemisia argyi, Cordate houttuynia had the repellency on adults and larvae. No significant effect of contact insecticide on Triboliu castaneum adults and larvae showed in 7 plants extract.
