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。

The thresholds of sound signal perception in the presence or absence of a continuous background sound were compared on 6 subjects. When both the signal and the background sound were pure tone of the same frequency, the thresholds of signal perception in the presence of weak background sound (0-5 db above threshold) were about 8 db lower, in average, than when the background sound was absent. This lowering of signal perception threshold was explained as a result of sensibilization of the auditory...

The thresholds of sound signal perception in the presence or absence of a continuous background sound were compared on 6 subjects. When both the signal and the background sound were pure tone of the same frequency, the thresholds of signal perception in the presence of weak background sound (0-5 db above threshold) were about 8 db lower, in average, than when the background sound was absent. This lowering of signal perception threshold was explained as a result of sensibilization of the auditory system by the background sound. Such kind of sensibi-lization effect was not eliminated by the masking of white noise. It, however, did not appear, if the signal differed from the background sound in frequency in more than 10 cps.

本工作在6名受试者身上比较了在有及无连续背景声作用下声音信号感受阈的变化。当信号及背景声为频率相同的纯音时,弱背景声(强度为阈上0—5分贝)能使信号感受阈降低8分贝左右。在有白噪声干扰的条件下,这一作用仍然存在。信号感受阈的降低是弱背景声提高了听觉系统对信号感受能力的结果。当背景声与信号有较大的频率差时,弱背景声即无降低信号感受阈的作用。

Differential thresholds of loudness (△I/I) were determined on 5 subjects for different signal durations (t) by both the signal comparison method and the method of beat perception.△I/I obtained by the first method did not seem to change with the change of signal duration (△I/I=K), whereas △I/I obtained by the second method varied systematically: when t was shorter than some critical duration T, △I/I were inversely proportional to the square root of t, i.e. △I/I=K'(T/t)2/2; when t was longer than T, △I/I...

Differential thresholds of loudness (△I/I) were determined on 5 subjects for different signal durations (t) by both the signal comparison method and the method of beat perception.△I/I obtained by the first method did not seem to change with the change of signal duration (△I/I=K), whereas △I/I obtained by the second method varied systematically: when t was shorter than some critical duration T, △I/I were inversely proportional to the square root of t, i.e. △I/I=K'(T/t)2/2; when t was longer than T, △I/I became constant, i.e. △I/I=K'. T was about 150 msec. The results were compared with the previous data dealing with the role of signal duration in pitch differentiation.

本工作用两种方法研究了声音的响度辨别阈(△I/I)与信号时程(t)的关系.用信号比较法测得的△I/I不受t的长短的影响,即△I/I=K.用拍感受法测得的结果却有所不同:当t短于极限时间T时,△I/I与t的平方根成反比,即△I/I=K'(T/t)~(1/2);当t长于T时,△I/I趋于恒定,即△I/I=K';T约为150毫秒.用拍感受法测得的响度辨别阈与信号时程的关系,和以前测得的音调辨别阈与信号时程的关系十分相象.
