The Tertiary relic genus Catalpa,containing 11 Old and New World species,has multiple necturies in the junctions of the major veins on the lower leaf surfaces.The generalized structure of the neetaries consists of a single,basal cell,and a single row of vertically oriented secretory cells.The nectaries are small,and contain no vascular tissue.Glandular and nonglandular trichomes are also present on the leaves.The glandular trichomes are structurally very similar to the nectaries,anti pro- bably are their precursors....

The Tertiary relic genus Catalpa,containing 11 Old and New World species,has multiple necturies in the junctions of the major veins on the lower leaf surfaces.The generalized structure of the neetaries consists of a single,basal cell,and a single row of vertically oriented secretory cells.The nectaries are small,and contain no vascular tissue.Glandular and nonglandular trichomes are also present on the leaves.The glandular trichomes are structurally very similar to the nectaries,anti pro- bably are their precursors. Development of multiple nectaries in the lower leaf surface vein axils is considered to be an advanced strategy for attracting beneficial insects to control or minimize the effects of herbivorous insects.Chinese and American species of Catalpa are closely related,and have greater numbers of nectaries in more locations on the lower leaf surface than west Indian species.Herbivory pressures in the West Indies are postulated to be lower than on the continents,i.e.Asia and North America.

第三纪残留的梓树属(Catalpa),共有十一种分布在新旧世界,此类植物叶片的下表面主脉连接处有多数蜜腺。这些蜜腺的一般结构具有一个单一的基细胞以及一列纵行排列的分泌细胞。蜜腺小而且不具维管组织。叶上还有腺性及非腺性的毛状体。腺毛构造与蜜腺相似,可能是蜜腺的前身。我们认为叶片下表面脉腋有多数蜜腺的发育,对吸引有益昆虫以控制或减少噬食植物昆虫的为害是一种进步策略。中国种与美国梓属的种是密切相关的,叶下表面比西印度的种具蜜腺的数量更多,蜜腺分布部位也更多。这可假设在西印度群岛食草动物的压力比在大陆(即亚洲和北美洲)较小。

ne of the most crucial events in the life cycle of herbivorous insects is the selection of a suitable site for oviposition. Chemical stimuli play an important role in mediating the behavioral steps leading to oviposition. Abiotic and biotic environmental factors often influence the production or release of behavior-modifying chemicals by plants,and therefore,affect the oviposition prefer-ences of insects.This review intreduces the recent research progress in this area,with special em-phasis on...

The present paper deals with the characteristics of species richness and diversity of the arthropod communities in different rice fields and at various growing stages of rice based on the data obtained from field surveys and the measurement of the community diversity. The field surveys were carried out in three different forations which represented three typical rice-growing habitats: mountainous,plain and hilly fields in the suburb of Fuzhou, Fujian Province in 1994.

The present paper deals with the characteristics of species richness and diversity of the arthropod communities in different rice fields and at various growing stages of rice based on the data obtained from field surveys and the measurement of the community diversity. The field surveys were carried out in three different forations which represented three typical rice-growing habitats: mountainous,plain and hilly fields in the suburb of Fuzhou, Fujian Province in 1994. Shannon-Wiener's (1949) average information content(H) , Hurlbert's(1971) probability of interspecific encounter (PIE) and Pielou's (1966) formula of equitability (E) were used to measure the diversity of the arthropod communities in the ecosystem of rice fields. The result showed that the species richness of herbivorous insects, carnivorous insects, spiders and total species in the community varied with different fields because of the influence 0f environmental variables in the habitats, and fluctuated with various growing stages of rice due to the variation of crop nourishment. Changes in the index values of H, PIE and E indicated that the community diversity and equitability also varied with space (habitats formed by the rice fields) and time (growing stages of rice). The author thinks that the results of the study could be applied to predict and forecast the population dynamics of rice pests, and to develop the rational program of integrated pest management in the specific rice fields. Discussions are also given in some detail on the methodology of measurement of the species richness and diversity of the arthropod communities in rice fields.

本文根据田间调查的资料和群落多样性指数的测定,比较了不同稻田和水稻不同生育期节肢动物群落物种丰富度及多样性。田间调查于1994年在福建省福州市郊区选择3种具有代表性的水稻种植区进行,在此基础上,作者运用Shannon-Wiener(1949)的平均信息(H)、Hurlbert(1971)的种间相遇机率(PIE)和Pielou(1966)的均匀度(E)指数来测定和分析稻田生态系统中节肢动物群落的丰富度及多样性。结果表明,由于受到稻田生境中各种环境因素及水稻不同生育期营养状况的影响,稻田节肢动物群落的丰富度及多样性不仅因田而异,而且随着水稻的生长发育过程有较大的波动。作者认为,稻田节肢动物群落丰富度及多样性的研究结果,可为水稻害虫的预测预报和综合治理提供重要的科学依据。文中还就群落丰富度及多样性的测定方法问题进行了讨论。
