| 1. | Insect population dynamics has always received much attention . 昆虫种群动态的研究一直受到重视。 |
| 2. | He used aphid fecundity data to elucidate the theoretical effects of antibiosis on insect population dynamics . 他利用蚜虫繁殖力资料说明了抗生作用对虫口动态的理论效应。 |
| 3. | Application of taylor ' s power law to sampling design of insect population 幂法则在昆虫种群抽样设计方面的应用 |
| 4. | The majority of insect populations trapped on the island were brought from the mainland by winds with several species locally bred 在长岛县的小岛上诱到的昆虫种群只有少数几种是当地繁殖的,大多数是由风从大陆携带而来。 |
| 5. | This provides what is called a " refuge " and is used to manage the genetics of pest insect populations to prevent the development of resistance to bt in insects feeding on the corn 正如总统所说:有一个具相互责任和社会安全的法律架构,对市场非但没有破坏性,反而对其成功至关重要。 |
| 6. | In an epa meeting on gm crops last fall vaituzis acknowledged the lack of long - term data on bt crops and insect populations . such studies require more time than has been available since the registration of bt crops vaituzis remarked 2000年秋天,在环保署的一个基因改造作物会议中,卫图吉斯承认他们缺乏bt作物和昆虫族群的长期研究资料。 |
| 7. | Actually the spermatozoa and the ova have the same importance in the process of the insect population multiply , so the studies on the spermatozoa should be strengthened in order to understand the detail of the insect generative physiology 而实际上在昆虫种群的繁衍过程中精子与卵子有着相同的重要性,为此想全面了解昆虫的生殖生理还必须加强对精子的研究。 |
| 8. | You should buy ant or cockroach traps instead of fluorocarbon sprays ; they are less polluted and can reduce insect populations effectively . you should also try to minimise your purchases of products such as aerosol sprays that contain ozone depleting substances 避免使用含碳氟化合物的灭虫喷雾剂,改用? ?屋等灭虫蚁装置,既可有效减少虫蚁的数目,又可减低污染程度。 |
| 9. | Then our work can be greatly reduced , which is difficult to be done in the past . what especially interests us is the real sense of the dynamic equations on tune scales . for example , it can model a land of insect populations 这样做不仅大大地减轻了人们的工作量,而且迅速地扩展了我们研究方程的范围,使我们对其它各类时间模上的方程也能加以了解,这是以前我们很难做到的。 |
| 10. | The entomophthoralean fungus , pandora delphacis ( hori ) humber , ( zygomycotina : entomophthorales ) is an insect pathogen specific to homopteran insects such as planthoppers , leafhoppers , and aphids and frequently cause epizootics in insect populations . problems with propagation of inocula at a low cost , but high efficiency , have been a technical obstacle to progress for entomophthoralean study and utilization for a long run 飞虱虫疠霉( pandoradelphacis ( hori ) humber )是同翅目昆虫的专性昆虫病原真菌,分类上属于接合菌亚门( zygomycotina )的虫霉目( entomophthorales ) ,常引发飞虱、叶蝉的流行病,也侵染蚜虫、沫蝉等寄主。 |
