The time required for the embryonic development of Dolerus tritici Chu at 27℃ is about 7days. Both the mode of cleavage and the formation of the germ band are in common with otherinsects. At very early stages, the amnion degenerates without formation of a dorsal organ, butthe serosa persists until eclosion. The gastrulation is accomplished by means of an invagination ofthe germ band, the endoderm (mesenteron rudiment) being of bipolar origin.

The time required for the embryonic development of Dolerus tritici Chu at 27℃ is about 7days. Both the mode of cleavage and the formation of the germ band are in common with otherinsects. At very early stages, the amnion degenerates without formation of a dorsal organ, butthe serosa persists until eclosion. The gastrulation is accomplished by means of an invagination ofthe germ band, the endoderm (mesenteron rudiment) being of bipolar origin. During embro- genesis the germ band divides into 19 segments: 5 cephalic (including the acron), 3 thoracic and11 abdominal. The premandibular segment bears no appendages and disappears in the early stage;the antennae are post-oral in origin but soon migrate forward into pre-oral position; the labrum isunpaired, therefore represents no true appendage. The blastokinesis consists of the shortening of the dorsally flexed germ band and the bendingof its caudal end to the venter. During blastokinesis, the process of doxsal closure of the embryois completed. A neural groove, which appears behind the mouth and extends to the caudal end, gives riseto the ventral nerve cord. The protocerebrum, the duetocerebrum and the optic lobes arise fromthe pre-oral ectoderm. In the begnning, the stomodeal nervous system appears as two outgrowthsfrom the dorsal wall of the stomodeum. The mesenteron is formed by two masses of endodermal cells (mesenteron rudiments) situatedinner to the blind ends of ectodermal stomodeum and proctodeum. At the end of proctodeum thereare outgrowths which developing into Malpighian tubules. There are 14 pairs of ectodermal invaginations altogether present. Of these 4 pairs in the headgive rise in succession to the anterior tentorial arms, the mandibular apodemes, the posterior tentorialarms and the salivary glands; while those occurring in meso- and metathorax and in first to eighthabdominal segments develop into tracheal and form the tracheal system. Originally the oenocytesare ectodermal cells which invaginate at first alone with the abdominal tracheal and later lose theirconnections with the integument. The median mesoderm gives rise to haemocytes, the splanchnic mesoderm forms the muscularcoat of the digestive tube, while the somatic mesoderm develop into the skeletal muscles as well asthe fat bodies. Those cells which occur at the junction of the splanchnic and the somatic layersform the dorsal vessel and the dorsal diaphragin. Anteriorly the aorta is formed by the union oftwo coelomic sacs of the acron.

(1) The photically evoked response of the compound eye and optic lobe of the cockroach (Periplaneta australasiae) was led by means of micropipette electrode filled with 10% K_4Fe(CN)_6 approaching the eye from the stalk of the optic lobe. This electrode also served as a differential lead in conjunction with a fixed subcorneal electrode.

(1) The photically evoked response of the compound eye and optic lobe of the cockroach (Periplaneta australasiae) was led by means of micropipette electrode filled with 10% K_4Fe(CN)_6 approaching the eye from the stalk of the optic lobe. This electrode also served as a differential lead in conjunction with a fixed subcorneal electrode. (2) It was found that the microelectrode nearly inevitably developed a kind of oscillatory potential upon touching the basement membrane which was evidently a rigid structure. With reference to the basement membrane, other structural levels of the optic lobe and the eye could be determined accurately. The structure of the eye and optic lobe was described briefly. (3) A spot-light (dia. 150μ), an annulus (inner dia. 150μ, outer dia. ~1mm) and a circular patch of light (~1mm dia.) were used to study the form and additivity of electroretinogram (ERG) to different patterns of stimulation. It was found that the ERG generated in different areas of the retina was additive, and its form, was independent of the shape of the stimulating light. No evidence was found to indicate the existence of a genuine local response corresponding to the local ERG of the vertebrate eye. (4) The ERG of the cockroach is a pure negative wave, in which two components, N_1 and N_2, can be distinguished. Both components can be recorded along the depth of the layer of retinula cell practically without decrement. Slightly below the basement membrane, N_2 can be recorded relatively in isolation from N_1. A positive component arising from medulla externa does not spread electrotonically to the compound eye. (5) Increasing light adaptation suppresses N_1 at a faster rate than that of N_2. (6) The discrepancies in the interpretation with regard to the site of production of various ERG components of the compound eye of Periplaneta and certain other insects were discussed.

(一)用一个10% K_4Fe(CN)_6灌注的玻璃微电极記录了大蠊复眼及視叶不同深度部位对光刺激的电反应。这个电极是从对侧复眼插入的,它同时又与另外一个固定的角膜下电极作为辨差引导。对某些深度的电反应曾加以分析。 (二)电极接触基底膜时,无例外地产生一种振动电位;根据基底膜的位置卽可准确地断定复眼及視叶其他結构的位置。对复眼和视叶的結构曾簡单地加以描述。 (三)用小光点(直徑150μ)、光环(內徑150μ,外徑約1mm)和圓形光(直徑約1mm)刺激,檢查了視网膜电图的相加性和波形是否因刺激形状的不同而有所改变。結果表明,大蠊复眼視网膜电图是完全可以相加的,单相引导出的电位的形状与刺激光的形状无关。沒有証据指示在昆虫复眼有相当于脊椎动物的局部視网膜电图的存在。 (四)大蠊視网膜电图为一純负波,在这个负波里,可区別两个成分,N_1和N_2,它們在整个小网膜細胞层都可以不衰减地被記录出来;在基底膜紧下,主要只記录到N_2。視叶的外髓层也有一个正向电位反应,但它的电場不到达复眼。 (五)漸次增强明适应,N_1比N_2更快被压抑。 (六)对于大蠊視网膜电图某些部分的起源以及与其他某些昆虫的不同,本文曾加以...

(1)The scotopic spectral sensitivity curve with its maximum at 490 nm of theround scad shows a relatively heightened sensitivity in the short wavelength regionand a ‘shoulder’between 523 nm and 560 nm as compared to the absorption spectrumof the rod pigment.The former has been proved to be the result of scattering propertiesand fluorescence of the cornea and lens,while the latter has been interpreted by thepresence of another pigment with its maximum sensitivity at rather longer wavelengthin the retina or the participation of the action of the photopic(cone)system even underscotopic conditions.The curve of the Japanese mackerel has its maximum at 480nm and fits fairlywell with the absorption spectrum of the rod pigment.(2)When the intensity of white background light on the cornea attains 4.07μw/cm~2,the peak of the spectral sensitivity curve of the round scad is displaced some30 nm toward the long wavelength,i.e.at 520 nm(Purkinje shift).The intensity atwhich the Purkinje shift occured seemed rather higher(40.7μw/cm~2)for the Japanesesmackerel,its photopic spectral sensitivity curve has a peak at 525 nm.

1.鲹ERG b波的暗视光谱敏感曲线峰值在490毫微米,和视色素吸收光谱相比较,短波段(小于456毫微米)曲线上翘,长波段也偏高。前者已证明主要是由于角膜和水晶体的散射和萤光特性,后者可能是由于网膜内包含另一种敏感峰偏长波段的色素,或在暗视条件下有明视系统参与活动。鲐的暗视光敏曲线峰值在480毫微米,和视色素吸收光谱吻合得很好。2.当背景光强(白光)达到一定水平(4.07微瓦/平方厘米),鲹的光敏曲线发生浦肯野位移,峰值移至520毫微米。鲐发生浦氏位移的光强水平要高一些(40.7微瓦/平方厘米),峰值移至525毫微米。
