In 1984-1955, the ecology of Sand badger was observed in Long Xian, Shaanxi province, including habitat type, life habit, food, breeding, molt, natural enemies and parasites. 115 specimens were collected month by month in one year, the length-weight relationship of sand badger may be expressed as follows: : W = 0.00023L~(2.65028), : W = 0.00047L~(2.53922), W standed for body weight, L standed for body length, a and b were both constants. 1984—1985年,作者在陕西省陇县关山林区研究了猪獾的生态,包括栖息地类型、生活习性、食性、繁殖、换毛、天敌和寄生虫。 This paper deals with thd Early-Middle Devonian bivalves of Guangxi, with an approach of ecology. On the basis of the features of composition, life-habits of the Early-Middle Devonian bivalve faunas, the depositional environments of Guangxi are also mentioned. 本文从古生态角度研究广西早、中泥盆世双壳类化石,并根据双壳类的生活习性探讨沉积环境,这类研究在国内尚属首次尝试。 本文的第一部分详细讨论了广西早、中泥盆世双壳类的地理、地史分布,动物群特征及其化石组合序列,指出本区是世界泥盆纪双壳类发育中心之一。本文的第二部分在大量观察我国沿海潮间带及部分潮下带现生双壳类生活习性基础上,分析、讨论它们的功能性形态,进而对研究区泥盆纪的内生潜穴、半内生、表生及假漂浮双壳类的生活习性进行详细分析,分别绘制了不同时期双壳类生活习性复原图。本文的第三部分详细讨论了本区不同时期、不同种类及不同生态单元双壳类的分布及其与岩相和底质的关系。指出本区的潮下带—半局限盆地相带、开阔台地相带的双壳类最为繁盛,分异度高,而较深水台沟相带双壳类属种单调。此外还指出本区早埃姆斯期早时的双壳类在粉砂岩、粉砂质泥岩及泥岩中最为丰富;一些属种对某些底质有明显的选择性。根据不同时期双壳类动物群特征及生活习性讨论了广西早、中泥盆世沉积环境的变迁;并依据双壳类化石碳、氧同位素组成,对本区泥盆纪的古盐度、古温度进行了推算。 Biological characteristics of the Cowpea weevil has been studied more systematically. The life history, life habit, oviposit habit, quantity of oviposition, hatch rate, emergence rate, last of different stages of the Cowpea weevil and the relationship between its development and temporature, humidity, kinds of grain and moisture content of grain were clarified. The host range, within which the Cowpea weevil can be destructive, was also investigated, indicating 13 kinds of legumes, oilseeds and grain, among which... Biological characteristics of the Cowpea weevil has been studied more systematically. The life history, life habit, oviposit habit, quantity of oviposition, hatch rate, emergence rate, last of different stages of the Cowpea weevil and the relationship between its development and temporature, humidity, kinds of grain and moisture content of grain were clarified. The host range, within which the Cowpea weevil can be destructive, was also investigated, indicating 13 kinds of legumes, oilseeds and grain, among which legume is the one damaged the most severely. It was found that peanut and wheat were also suffered from its attack. 本文比较系统地研究了四纹豆象的生物学特性.基本摸清了此虫年生活史、生活习性、产卵习性、产卵量、孵化率、羽化率、各虫态历期以及四纹豆象生长发育与温湿度、粮种及含水量等的密切关系.弄清它能危害寄主范围和供试的豆类、油料、粮食等13个品种,其中对豆类危害最严重,也发现对花生仁和小麦的危害.四纹豆象还具有耐干、耐热等特性.
