The present paper is a review of the experimental results of current researches concerning foodpreferences and nutrition of plant-feeding insects. Stress has been laid on the roles played by the sensory discriminations and nutritional requirements in the selection of host plants. The effectivevisual, olfactory, tactile and gustatory stimuli emitted from plants may be classified as attractive orrepulsive for insects during food-finding and phagostimulative or phagoinhibitive for insects duringfeeding.

The present paper is a review of the experimental results of current researches concerning foodpreferences and nutrition of plant-feeding insects. Stress has been laid on the roles played by the sensory discriminations and nutritional requirements in the selection of host plants. The effectivevisual, olfactory, tactile and gustatory stimuli emitted from plants may be classified as attractive orrepulsive for insects during food-finding and phagostimulative or phagoinhibitive for insects duringfeeding. The same may be applied to oviposition of the adult females whose offspring will feedon the same plant where they lay their eggs. Descriptions are given for the nature of the varioussensory stimuli and the characteristics of responses of different insects. In establishing nutritionalrelations with their host plants phytophagous insects of various food habits conceived as oligopha-gous, polyphagous, etc. perhaps all may subject to the action of favourable as well as unfavourablestimuli. Sometimes these two categories of stimuli may not be confined to the 'odd' substances ofplant origin, as revealed by the fact that some species have been reared successfully with artificialmedia of purified chemicals. Since food preferences may imply the possibility of maintenance of a population of an insect ona particular plant species, the roles played by nutritional requirements and the capacities of fooddigestion and utilization and of tolerating or omitting detrimental actions of toxic substances inplants are also important factors. These are the manifestations of the metabolic peculiarities ofdifferent insect species and different individuals of the same species. Although there are manysimilarities in the nutritional requirements of the phytophagous species so far studied, one cannotdisregard the functional adaptation in the differential utilization of the chemical constituents ofplants. Viewing the facts that nutrients such as sugars and amino acids may be used as phagostimu-lants and that the genral nutritional condition of the insect may also affect the threshold ofsensory perception and the frequency of occurrence of dispersal movements which may lead to thechange of the relation with the host plant or the location of feeding, one may agree to the genera-lization that thee are relations between host specificity and nutrition. Various theories concerning the causes of host specificity are examined and discussed.

本文综述和讨论近年来有关植食性昆虫食性和营养的研究结果和发展。第一部分略述该类昆虫食物因理化性质的各异所引起的食性特化现象,由此所产生的研究课题和国际对这方面的研究动态。第二部分叙述昆虫的感觉作用和食料植物选择之间的关系,列举对不同昆虫在觅食或产卵时有诱致或驱斥效应的和在取食时有助长或抑制效应的感觉刺激的本质和昆虫反应的特点。第三部分讨论植食性昆虫的营养和代谢的特点及其与食性特化的关系,在列举较近期间的研究成就后指出在不同种类中所存在着的营养差异,可能和食性特化有某些联系。这类昆虫的营养需要和对植物中有毒物质的适应都是代谢类型的反映,它们和昆虫的感觉反应有一定的联系,在与植物建立营养的关系中同样是重要的。第四部分叙述并讨论了有关植食性昆虫食性的某些理论,其中包括在选择食物中的机制、食性形成的主导因素、对食性类型以及食性演化的解释等。最后,指出对有关方面研究的可能进展和成就,及其在昆虫学各方面所起的影响。

An automatic radon measuring instrument type JSZ-2 for observing the continuous change of radon concentration of underground water in the search of earthquake precursors is described in this paper. It consists of four essential portions, namely, (1) continuous degassing device made of glass; (2) automatic programming controller of timing; (3) scintillation impulse counter; (4) digital repeated recorder.The set can be used to record intermittently or continuously for radon content of underground water, maximum 1,000 Emans, with errors ±10%. The quantity of water flow Qwater=2.0 liters/minute and of gas flow Qgas=200-450 milli-liters/minute. Sensitivity is about 800 impulses/minute/Eman., response, less than 5 minutes, efficiency of degasification about 50%.Under various conditions, this instrument has been subjected to tests for its actual performance. It can be said that in comparison with instruments of similar nature, made both in China and abroad, this instrument has the characters of better direct viewing, higher sensitivity and reliability, ease of operation, etc. Particularly, the glass degassing device has the advantage of anti-corrosion, ease of cleaning and low cost. The instrument can essentially meet the requirements of Radon observation in earthquake areas.

This paper introduces a new method by which fluorescent mini-tuft is used to view the flow on the body surface and to record it by photography in low and high speed wind tunnels. The size of the fluorescent mini-tuft is about 10-20 microns in diameter.

This paper introduces a new method by which fluorescent mini-tuft is used to view the flow on the body surface and to record it by photography in low and high speed wind tunnels. The size of the fluorescent mini-tuft is about 10-20 microns in diameter. Our experiments have proved that fluorescent mini-tuft stuck on the model has no significant effects on the results of force testing. Suggest that as soon as the manufacturing of the testing model is completed, fluorescent mini-tuft be stuck on it so that the force measurement and flow viewing on the body surface may be carried on simultaneously.Fluoresccnl: mini-tuft has been used for viewing the flow patterns on wings of six different shapes.Three of them are selected from reference [1] so that comparison may be made between this method and the oil flow method.

本文介绍了一种使用萤光微丝来观察物体表面流谱的新方法。这种方法不仅适用于低速风洞中实时观察流谱,或用照相方法记录流谱,并且也适用于跨、超音速风洞中观察或记录流谱。实验证明,由于萤光微丝的尺度极小(直径仅为10~20微米左右),风洞试验模型粘贴萤光微丝后,对测力试验的结果影响不大,在实验误差范围之内。故建议在风洞试验模型加工完毕时,即粘贴萤光微丝,以便随时观察流谱,并进行测力试验。 我们在低速风洞中,进行了六种平面形状机翼的萤光微丝法流谱观察,并就其中几种平面形状机翼与资料中的油流流谱进行了比较。
