| 1. | They deposit larvae that will grow up to egglaying females . 它们产生幼蚜,以后发育为产卵雌蚜。 |
| 2. | Aphid count on plants in fields do not correlate with virus spread in the same fields . 田间植株蚜数与同块田内病毒的扩散程度间无相关性。 |
| 3. | In summer, virus spreads also from outside the field and cannot be stopped by aphicides . 在夏季,病毒传播也来自田外而且不能用杀蚜剂阻止。 |
| 4. | The grape phylloxera had disastrous effects on the french grape crop and wine industry . 葡萄根瘤蚜对法国的葡萄生产和酿酒业带来了灾害性影响。 |
| 5. | Large catches of alates may be trapped in areas where the aphid population in the field is extremely small . 在蚜群极小的田间可诱捕到较多的有翅蚜。 |
| 6. | I have seen small population almost wiped out by fungus at the same time as dense aphis populations elsewhere . 我曾见到小的群体在其它任何地方的高密度蚜群被真菌杀死的同时差不多也被杀死了。 |
| 7. | This will vary with the local or total number of virus sources, but also with the efficiency as a vector of the prevalent aphid clones . 带毒蚜的多少因地区或因毒源总数而异,但也与优势蚜群传毒力有关。 |
| 8. | It is clear that pterocommatinae is closer to a . pisum 表明群蚜科与毛管蚜科近似。 |
