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.

Clinically most of the deaths from tartar emetic intoxication were due to cardiac impairment,and animal experiments also demonstrated depression of the heart.The present work investigated the hemodynamic effects of tartar eme- tic in order to elucidate the circulatory disturbance during its intoxication. In 26 dogs,anesthetized with chloraloso,cardiac output was estimated by Fick’s principle.Cardiac catheters were inserted under fluoroscopic guidance.Blood was drawn from pulmonary artery and aorta,and the oxygen content was analyzed by Roughton-Scholander's method.Electromanometer was used to measure the pressure in pulmonary artery and right atrium.Oxygen consumption was determined with a BMR apparatus which was connected to a tracheal cannula.The normal values (mean±s.d.)were:cardiac output 1.94±0.6 1/min,cardiac index 3.0±0.9 1/min/m~2,stroke volume 11±3 ml,aortic mean pressure 168±21 mm Hg,pulmo- nary arterial mean pressure 20±6 mm Hg,total peripheral resistance 8000±2800 dyne.sec.cm~(-5),work of left ventricle 7.1±2.4 kg.m/min/m~2,and work of right ventricle 0.65±0.31 kg.m/min/m~2. In the control group,there was no remarkable change in the cardiac hemody namics within 5 hours. An intravenous injection of a therapeutic dose of tartar emetic(2 mg/kg) did not produce significant effects on the cardiac hemodynamics. A toxic dose(15 mg/kg)induced a noticeable hypotension.Electrocardiogram revealed a flattening or inversion of T wave.The change of the total periphera resistance was,however,not great. When the dosage was increased above 20 mg/kg,the cardiac depression be- came marked,with gradual weakening of the left ventricle.The work of the right ventricle was first increased in compensation for the augmented pulmonary re- sistance,and then decreased.The total peripheral resistance rose tremendously,indi cating constriction of most arterioles.Thus the hypotensive effect of tartar emetic was attributed chiefly to cardiac depression.The dogs died in 4—5 hours.

吐酒石中毒死亡病人大多死于心臟因素,动物实驗也表現有抑制心脏作用,本文从心臟血流动力作用的变化来說明吐酒石中毒时的循环障碍。狗26只,三氯醛糖麻醉,根据Fick氏原理测定心輸出量。在X光透視下插心脏导管取肺动脉及主动脉血,用Roughton-Scholander氏法测定血氧含量。基底代谢测驗器測定氧消耗量,电測压计測定右心房及肺动脉平均压。給藥前各項正常数值(平均±标准差)为:心輸出量1.9±0.6升分,心臟指数3.O±0.9升/分/米~2,心搏量11±3毫升,主动脉平均压168±21毫米汞柱,肺动脉平均压20±6毫米汞柱,总外周阻力8000±2800达因·秒·厘米~(-5),左心室作功量7.1±2.4千克·米/分/米~2,右心室作功量0.65±0.31千克·米/分/米~2。对照組狗在5小时内心輸出量及心搏量基本稳定,主动脉、肺动脉平均压及血管阻力均无大变化,心电圖正常,心室作功量无抑制現象。吐酒石的一次給藥量(2毫克/千克)未引起心臟血流动力作用的显著变化。吐酒石的中毒剂量在15毫克/千克时引起血压显著下降,心輸出量在2小时后似有减少傾向,心电圖T波变平或倒置,总外周阻力变化則不大。剂量在20毫克/千克以上...

This paper reports the results of studies on the nuclear polyhedrosis virus-of the cotton bollworm Heliothis armigera.The virus was isolated in 1974 from dead boll-worms collected from cotton fields in Chinchow district of Hupeh Province.It was designated as VHA-273.It is observed that the polyhedra are hexagonal,pentahedron,cubical or irregular in shape,varying from 1.25 to 5.0 p in diameter.Serious pathological changes were in the fat-body,epidermis,tracheal matrix and other tissues of the diseased insects and the former two seemed to be the most susceptible tissues.The muscle bundles were not affected.Our bioassay showed that the susceptibility of the larvae to the NPV varied with dosage,larval instar and temperature.The first and second instars were the most susceptible stages;and their mortality rates at 1×106 PIBs/ml were 85% and 80% and the time lasting were 6 and 8 days respectively.Larvae of fifth and sixth instars were not so susceptible,especially when the temperature exceeded 33℃.Cross infections of the NPV with tobacco budworm,Heliothis assulta,was susccessful.In 1975,from July to September,field tests with the NPV to control bollworms were made in cotton fields about 102 mil's at Kung-an County of Hupeh Province.The concentrations used were 1.5×1010 PIBs/mu,3×1010 PIBs/mu and 6×1010 PIBs/mu.The results showed that the NPV was better than the chemical insecticides 1605+DDT.Combined use of the NPV with dilute sevin and Bacillus thurin-giensis suspensions were also tested;and the results were either better or as effective as the NPV or sevin used alone.The application of the NPV VHA-273 to control bollworms in the field seems promising.

自1973—1974年以来,在湖北荆州地区微生物站筛选出一批棉铃虫病毒毒株,其毒力均为80%以上,有的高达100%。其中毒力较强而又比较稳定的VHA-273,经病虫组织切片观察,确定其为核多角体病毒。1974—1975年除对棉铃虫病毒病的组织病理变化作了初步观察外,又继续在室内外对病毒的毒力、剂量与虫龄、温度的关系,及寄主饲料对病毒产量的影响等,进行了一系列的试验,并用VHA-273生产部分病毒,为大田防治试验作了准备。 1975年7—9月,用VHA-273生产的病毒,在湖北公安县雷州公社约102亩的早发棉田进行示范试验,对第2代及第4代棉铃虫的防治效果,先后调查了5次,最后对试验田、对照田及邻田又作了天敌调查,结果均表明试验田的虫口下降率,花、蕾及青铃受害率等,均低于1605+DDT及西维因的对照田,为棉田的生物防治提供了有希望的微生物农药。 VHA-273棉铃虫核多角体病毒,对烟青虫的毒力很强,对两种害虫能交叉感染。因此,它可用于烟青虫的防治。
