应用扫描电镜观察七星瓢虫Coccinella septempunctata的唇须和附节,以便确认在感应农药残留时起主要作用的化学感受器。研究证明分布在下颚须上的感器类型包括两种锥形感器（兼有机械感受器和化学感受器的功能）和一种钟形感器。同时本文首次报道了对这些感器精确的形态测量,明确了其性二型性。对下颚须的测量表明其左右末节的长度差异与七星瓢虫的性别之间有明显的相关性。文中还记述了下唇须上一种新的钟形感器,其在每个下唇须上的数量大约为12 ~17个。经测量这些机械感受器的平均直径为2.4μm。早期研究中所记述的锥形感器被证实是下唇须上仅有的化学感应器,并且首次证明这些锥形感器的数量与性别相关,雄性平均为18个,雌性平均为16个。附节上也存在性别差异：第2跗节跗垫的宽度在雄性中是从后向前逐渐增大,而在雌性中刚好相反。本文还就这些差异的意义以及新发现感器的功能进行了讨论。

Three kinds of.plant growth regulators, gibberellinA 4/7 （GA 4/7 ）, 6-benzylaminopurine （BA）, and chlormequat chloride （CCC）, were evaluated f.r their ability to promote strobilus and cone production in a Chinese pine （Pinus tabulif.rmis Carr.） clonal seed orchard. Treatments （0, 250, 500, or 1000 mg L -1 ） were applied during three periods （June- July, July-August and August-September） in 2005. Of.the three plant growth regulators, GA 4/7 was the best f.r promoting f.ower and cone production. Trees sprayed with GA 4/7 （500 mg L -1 ） f.om June to September had signif.cantly more f.male strobili and immature cones than controls and other treatments （p≤0.0001）. The best time to apply GA 4/7 was in June. BA at 500 mg L -1 signif.cantly increased f.male f.ower and immature cone production, compared to other treatments and controls （p≤0.0001）, while promotion of.male strobili was unchanged. Chlormequat chloride at 1000 mg L -1 signif.cantly increased the number of.male strobili, compared to the other treatments （p≤0.0001）. Spraying CCC at500 mg L -1 signif.cantly increased the number of.f.male strobili, compared to controls （p0.05）, but it had no ef.ect on immature cone production （p0.05）. These results are important f.r improving seed production and seed orchard management of.Chinese pine.
