摘  要：
研究了植食性鳃金龟科(Melolonthidae)的6个种和丽金龟科(Rutelidae)2个种的雌雄内生殖系统构造。雌虫生殖系统具一对卵巢,各有6个卵巢小管,但受精囊及附腺的形状在科与科,种与种之间存有明显差异。卵巢发育分为5级,可用于预测产卵时期。根据卵巢发育与成虫取食的关系,将8种金龟分为不需营养型、补充营养型和完全营养型。比较了不同营养类型与卵巢发育进度和生殖力的关系,从而为分析蛴螬种群数量动态和确定防治对策提供依据。

摘  要：
The reproductive systems of chafers of 8 species belonging to Melolonthidae and Rutelidae are described. The female system consists of paired ovaries each with 6 ovarioles, a spermatheca and an accessory gland open to the base of bursa copulatrix. The male system consists of a pair of six-lobed testes cohnected to the vasa deferentia. The morphological variation of the systems in different species are noted, especially. the spermatheca and apcessory glands which may be used as cues in specific classification. . Comparison has been made in the ovarian development in the adults after emergence.Based on the difference in the relation belween ovarian development and trophic activities of the adult beetles the 8 species of chafers can be divided into 3 types: 1. the nutritionally indif-ferent type in which the newly emerged female beetle contans fully developed ovaries, such as Holotrichia 韎tanis,- H. trichophora and Anomala exoleta, 2. the type in which ovarian maturation needs compiementary nutrition in.the aduls such as Holotrichia obilita and Anomala corpulenta, and 3. the type in which ovarian development completely depends on adult feeding, such as Holotrichia parellela, Trematodes tenebrioides and Serica orientalis. The differences among these types are important because they are determinative for fecundity and the longevity of the adult beetles. The fecundities pf chafers of the latter two types can be significantly influenced by their food plants; but the nutrition condition in the larval stage is also important. 'Our results indicate that the chafers with short preoviposition period and not attracted to light trap should be controlled in the larval stage. The species which depend on adult nutrition for ovarian maturation can be controlled in the adult stage and the suitable time to carry out chemical control can be decided through observing the sex ratio of chafers attracted to light trap and the stage of ovarian development. The species with high reproductive potential such as H. oblita and H. parallela which are irnportarnt soil nsects in tlie crop fields in North China should be monitored more closely.
