Themain results obtained from this study are summarized as follows: 1. This insect has three overlapping generations a year in the western part of Hunan province.The duration of a generation varies with temperature. The longest period is 42 days under anaverage temperature of 18-24℃., the shortest 33 days with temperatures at 24--26℃. The over-wintering generation requires about seven months. 2. In Hua-yuan district, this insect hibernates mainly in the open field. And flight comes tomaximum in middle and late April. 3. The results of field or indoor experiment on various organic insecticides (BHC & D. D.T.) indicated that the 6 percent gamma BHC was the most effective at a dilution of 1:100--300,and 25% D. D. T. at a dilution of 1:400--500.

Successions of parallel wind barriers are broadly used on vegetable plantations in North China during cold season. The details o?structure and dimension of the harries may vary from place to place and from time to time in accordance with the experience of the farmers. In general the barriers are about 1.5-2 meters high, 100-200 meters long and are made of millet stems or reeds. In order to protect the crops from the prevailing cold N-W wind, the fences are oriented in a west-east direction. The inclination and density of the fences are varied gradually with the season. In the winter and early spring the barriers are impermeable and inclined toward the south at an angle of about 60-70° to the horizon, and in the early summer they become eract and very open (blockage ratio less than 40%). The distance between two successive impermeable fences is usually about 5 meters and the crop growing area is confined within a narrow s'rip extending 2-3 meters to the south from each fence. The distance between two successive open fences as well as the width of the protected area may exceed 20 meters.In this paper, a preliminary investiga'ion on the micrometerological effect of the impermeable fences are given. Observations and experiments within the narrow growing strip show that:-1. The wind speed is severely reduced. In case of N-W wind at 25cm above the ground immediately to the lee of the fence air is mearly stagnent, and at a distance of about 2 meters from the fence the air speed may increase to about 35 percent of the free wind speed.2. The barriers shade the northern part of the sky and reflect the direct and diffused solar radiation coming from the south. The interaction between shading and reflection effect influence the total incoming solar radiation in such a manner that large amount of incoming radiation is associated with high fences, low cloud amount, low solar attitude, small distance from the fence, high reflectivity of the fences surface and among these the cloud amount is the most important one. It is found that at noon the total incoming solar radiation within the narrow strip may exceed that in the open appreciably when the sky is clear and is much lesser than that in the open in cloudy or raining days.3. The fences obscure a large solid angle of the sky so that the out going long wave radiation is noticeably reduced.In North China, the skies are generally clear in winter and early spring, especially after the passage of a cold front, the weather may usually be characterized by s'rong N-W wind and low turbidity and iA such a region the impermeable wind barriers rnay be of great usefulness.
