The horsefly, Tabanus griseus Krober, is one of the commonest species ofTabanids found in Peking. It is widely distributed in north-eastern, north andeast parts of China. This paper reports the result of a study on its life history andhabits conducted in Peking during 1951-54. Our observations show that this Tabanid begins to appear in early June,becomes abundant during latter part of June and throughout July. Here after thenumber decreases and after the middle of September it is rarely found in thefield. The seasonal activity therefore covers a period of about three and halfmonths. Six egg masses from which the issuing larvae were counted produced 456-842or in average 564 individuals. Under laboratory conditions, in the month of June andJuly, the average incubation period of the egg was found to be 4.5 days. Thelarvae molt within a few hours after hatching, and both the number and theduration of the larval stages are subject to a considerable variation. They normallypass through 7 or 8 larval stages but 6-10 larval stages also occurred. Under insec-tary conditions, the larval period for 52 individuals varied from 49 to 396 days.Those producing flies in the same year varied from 49-71 or in average 61.3 days,while those producing flies in the next year varied from 335 to 396 or in average 359 days. The average pupal duration for 52 individuals was 10.6 days. This Taba-nid is normally one generation per year. On a few occasions eggs daposited in Junecompleted their life histories in producing flies in early September. After feedingthese flies may deposit eggs and thus it is possible to have two generations a year. In the field, egg masses and larvae were found most frequently in rice fieldswhich seem to be the most suitable breeding place. Larvae have also been takenat the water edge of ponds with bulrush or other grasses growing, but on no occa-sion were larvae found near the sides of running water such as a river, a streamor a brook. This Tabanid passes winter in the larval stages, of which full-grownlarvae being the most common. In the field over-wintering larvae were usuallyfound in frozen soils 22-25 cm. below the surface on the edges of the rice fields. An egg-parasite, Telenomus sp., was found as a natural enemy. It is most com-mon in July and the parasiting rates of the egg masses of the Tabanid as found in1951 and 1953 were 34% and 23% respectively. Descriptions of immature and adult stages of Tabanus griseus are given; maleadult and the immature stages are described for first time. Measures for controling T. griseus are briefly suggested.

1.土灰虻是北京附近地区虻类的主要种类之一。它分布在东北、华北及华东等地。成虫为害牛、驴、骡等家畜。本文是1951—54年在北京进行生活史研究的一个报告。 2.土灰虻的成虫自6月上旬开始出现,6月下旬至7月下旬发生最多,9月中旬以后,则极少发现。全年的活动时间约为3(1/2)月。 3.本种虻的卵期平均为4.5日,每一卵块孵出的幼虫平均为564个。幼虫期在当年羽化的幼虫,平均为61.3日;在翌年羽化的幼虫,平均为359日。蛹期平均为10.6日。本种虻主要一年发生1代,仅有少数的个体当年可以发生第2代。 4.本种虻的孳生地主要在水稻田,在芦苇塘和长有窄长叶杂草的水塘亦常有孳生,但在河、溪等流动的水源则未有发现。本种以幼虫越冬,其中以成熟幼虫占极多数。越冬的处所多在堤岸下22—25厘米深的冻结土中。 5.本种虻有一种卵寄生蜂——黄胸黑卵蜂,寄生率达23—34%。这种卵寄生峰在7月间发生最多。 6.关于本种虻各虫期的形态,本文均有描述;其中雄虻及各幼期的形态,尚系初次记述。 7.根据生活史与习性的研究,对本种虻的防治问题,提出了几点意见;铲除田埂,清理池塘和积水洼地,利用天敌以及适当期间进行药治等。
