摘 要：
以天然存在的茵陈二炔（Ｃａｐｉｌｌｅｎｅ）为先导化合物，仿生合成了９个共轭二 块和３个单炔共１２个化合物。经生物活性测定表明：合成的聚乙炔类化合物对仓库害 虫具有一定的毒杀、抑制繁殖和行为控制作用．其中化合物２、５、９、１０试验剂量为 ０．０５％（ｗ／ｗ）时，能完全抑制米象（Ｓｉｔｏｐｈｉｌｕｓ ｏｒｙｚａｅ）的繁殖；化合物 ２、５、８、９、１０对锯 谷盗（Ｏｒｙｚａｏｐｈｉｌｕｓ Ｓｕｒｉｎａｍｅｎｓｉｓ）繁殖抑制率都在８０％以上．对赤拟谷盗（Ｔｒｉｂｏｌｉｕｍ ｃａｓｔａｎｅｕｍ）抑制率在 ８０％以上的有 ２、３、４、５、１０几种；化合物 ２、５、１０对米象 致死中浓度（ＬＣ_（５０））值分别为 ０． ０１２８％，０． ０２９５％和 ０．００６９％；处理 ９６ｈ后， 化合物５、６对赤拟谷盗成虫的忌避率分别为９７．４４％和９１．８９％；生化酶抑 制测定表明，化合物１０对乙酸胆碱脂酶具有明显的抑制作用，其它几种化 合物的毒杀机理有待进一步研究。

摘 要：
This paper reports the biological activities of twelve synthetic polyacetylenoid compounds against several stored-product insects. Trials under laboratory condition indicated a very high level of activity on poisoning. inhibiting reproduction and repelling. The LC_(50) of compound 2. 5 and 10 on Sitophilus oryzae are 0' 0128%. 0. 0295% and 0. 0069% respectively, they all can inhibit its reproduction completely. The majority of tested compounds can also inhibit the reproduction of both Oryzaephilus surinamensis and Tribolium castaneum and the rate of inhibition reach over 80% at the dose of 0. 05%. Compound 6. 7 exhibited the activity of repellent against the adult of Tribolium castaneum at the test of concentration 100μg/cm~2 and the retaining activity is 97. 44% and 91. 89% respectively for 96 hr. The result of enzyme assay in vitro in the larvae of Tribolium castaneum shows that compound 10 is an effective inhibitor of acetylcholinesterase.
