周尧  姚渭 《昆虫分类学报》1992,14(3):170-178
作者之一姚渭,1981年在其硕士研究生学位论文《中国蝉科分类的初步研究》89—92页(图50,图版XV:6-9)记载有新属周氏蝉属Chouia Yao,以纪念导师周尧教授,并记述了3新种,1新组合种,论文散发50余册,但未正式发表。 贺锦川1984年以同一类群建立拟红眼蝉属Paratalainga He,记述有2新种:P.reticulata He(=C.pulchra Yao),P.fusipenis He(=C.liuzhiensis Yao).论文正式发表在上海《昆虫学研究集刊》上,因此贺的属名和种名是有效的。  相似文献

中国棘蝇属二新种:双翅目:蝇科   总被引:1,自引:0,他引:1  
1983年采自吉林省长白山和1984年采自四川省周公山的棘蝇属标本,发现游荡棘蝇种团(erransgroup)中两个新种。命名为拟游荡棘蝇,新种 Phaonia mimerrans Ma,sp.nov.和次游荡棘蝇,新种Phaonia suberrans Feng,sp.nov.。前者与游荡棘蝇 Phaonia,errans(Meigen,1826)极近似,但新种的额较宽,间额明显;前陉有2—3个中位后鬃,可以区别,后者的后气门前肋裸,体大型,第一腹板裸,侧颜较狭等特征,可与本种团其他各种(errans,pseudoerrans Hennig,1963,asierrans Zinovjev,1981及mimerrans Ma,sp.nov.)区别。  相似文献

本文对Chang科Bagridae共4属8种鱼类进行了骨骼系统的研究,并对8种鱼的同工酶谱型进行了分析比较。应用分支系统学原理初步推导出Chang科的系统发育图。结果显示:Hu属较特化,黄颡鱼属次之,Wei属最原始,拟Chang属介于后两者之间。演化趋势表现为身体渐扁,逐渐平展,口渐阔,尾鳍从圆形到叉状进化。对Chang科8种鱼的鳍、肌肉、肝脏、肾脏、心脏、眼的晶状体和脑等7种组织4种同工酶(LD  相似文献

Functional response of a solitary, larval-pupal endoparasitoid of Liriomyza leafminers, Ganaspidium utilis Beardsley, was estimated on Liriomyza trifolii Burgess at three temperatures (17℃, 25℃, 29℃ ) and host densities. A type Ⅱ random parasitoid equation (RPE) was used to estimate instantaneous search rate and handling time. The instantaneous search rate increased as temperature increased. All of the RPE regressions obtained for functional response of G. utilis at different temperatures were significant (P〈0.01). The slope of RPE regression lines was lower across the temperatures. At 29±2℃, the maximum number of larvae parasitized was 7.8 per day. It decreased to 7.2 larvae parasitized at 25±2℃. At 17±2℃, no significant increment of parasitization was observed due to the host density increments. The estimated handling time was lowest at 17±2℃ and highest at 25 ± 2℃, respectively. The ability of G. utilis to find and parasitize L. trifolii over a wide range of temperatures makes them a good candidate for biological control of Liriomyza leafminers.  相似文献

Laboratory bioassays were conducted to determine the effect of food source on the survival of Tribolium castaneum Herbst, Oryzaephilus surinamensis L. and Rhyzopertha dominica F., after exposure to five diatomaceous earth (DE) formulations: Protect-It, Insecto, Perma-GuardTM, Dryacide and SilicoSec. Adults of these species were exposed to DEs at the rate of 0.5 mg/cm^2 for 1 day on filter paper inside plastic Petri dishes. After exposure, the initial mortality was counted and live individuals of the three species were held for a week in glass vials containing 50 mg wheat flour, rice and whole wheat, respectively. In the second experiment, after 1 day exposure to DEs, beetles were transferred to Petri dishes without food and held for a week to determine if the presence of food source would decrease the mortality of beetles. Experiments were carried out at 27℃ and 55% RH in the dark. The initial mortality in both of the experiments reached 100% for the three species exposed to Protect-It and in the case ofR. dominica and O. surinamensis exposed to Dryacide. In contrast, low level of mortality (〈 10%) was observed for T. castaneum exposed to Perma-GuardTM and Insecto. The mortality after the post-treatment period on food was decreased for the three species exposed to Perma-GuardTM and in the case of T. castaneum and R. dominica exposed to Insecto and SilicoSec. Adults of O. surinamensis were the most susceptible followed by R. dominica and 100% adult mortality was obtained, whereas T. castaneum were the least susceptible beetles to DEs. Protect-It and Dryacide were the most efficient DE formulations and can be used effectively in a stored grain integrated pest management program.  相似文献

大鳍Hu促性腺激素分泌调控的研究   总被引:9,自引:0,他引:9  
王德寿谷期  H.J 《动物学报》1998,44(3):322-328
用非洲鲶鱼促性腺激素放射免疫测定方法测定了Chang科鱼类样品中的促性腺激素含量。用这种方法和鲤鱼促性腺激素β-亚基放射免疫测定法测定大鳍Hu同一批血清样品结果也相当吻合。通过注射促黄体素释放激素类似物和/或多巴胺的D2受体拮抗剂地欧酮后,定时取样测定血清促性腺激素含量,证明大鳍Hu促性腺激素的释放同时受到下丘脑分泌的促性腺激素释放激素和多巴胺的双重调节。但是,多巴胺只能抑制由促性腺激素释放激素诱  相似文献
