前言当我们于1961-1963年在河北省代表地区进行蝇种调查时,根据采集的地点和蝇类结果一、丽蝇属各种丽蝇皆有嗜寒性,适应于低温高湿的环境,故其活动季节与多数蝇类相反;在活动的情况,对棲息习性作了初步了解(见表1)。在石家庄于1962年全年每月作了采集,以便观察其季节分布(见图1),现将结果报导如下。炎热的夏季几乎绝迹,于春季或初冬出现的数量很多。在冬季中午气温较高阳光充足时,也可看到少量成蝇在外界飞翔。在石家庄于10月开始出现,经整个冬季不断,5月下旬逐渐减少,7-9月消失。其活动场所相当广乏,在公园等处的小松树上,泥泞的猪圈内,向阳的墙壁上都很
Preface When we conducted a survey of fly species in the representative area of Hebei Province from 1961 to 1963, according to the collected sites and the result of flies, all the fly flies in this family were cold-blooded, adapted to the environment of low temperature and high humidity, Therefore, the season of activity is opposite to that of most flies; at the activity level, a preliminary understanding of habitat habits was made (see Table 1). In Shijiazhuang in 1962 year made a monthly collection in order to observe the seasonal distribution (see Figure 1), the results reported below. The hot summers are nearly extinct, with a large number occurring in the spring or early winter. In the winter at noon when the sun is high sunshine, you can also see a small amount of fly into the outside world to fly. Shijiazhuang in October began to appear, after the winter constant, gradually reduced in late May, July-September disappear. The venue is quite lack of activity, in the park and other small pine trees, muddy pigsty, sunny wall are very
