Variegate was lowest and reduced by 13% compared with normal environment without pesticide. The predating number of A.

结果］扑虱蚜浓度配比为1：2000，多异瓢虫完全取食率最低，比无农药环境下减少约13%。

2 kinds of imidaclopri pesticide, 70% imidaclop rid WDG and 20% Pushiya WP were to study the effect of low dose imidaclopri pesticide at different diluting ratio on the predation, function reflection of predation and reproduction of A. variegate. When 20% Pushiya WP was diluted at 1:2000 the predating rate of A.

方法］采用艾美乐70%水分散粒剂和20%扑虱蚜可湿性粉剂两种吡虫啉药剂，研究了不同低剂量吡虫啉农药的配比对多异瓢虫捕食、捕食功能反应、生殖力的影响。

Effects of transgenic Bt rice on predation and prey preference of wolf spider Pirata subpiraticus Function responses of spiders fed Bt prey or control prey both followed the Holling type.Ⅱ.

九、转Bt基因水稻对拟水狼蛛捕食功能反应和猎物选择性的影响以不同食料喂饲的两种拟水狼蛛对褐飞虱的捕食功能反应都符合Holling Ⅱ型反应。

Impacts of transgenic Bt rice on survival and growth of wolf spider Pirata subpiraticus Survivals and developmental duration of older spiderlings of Pirata subpiraticus after fed with BPH or Mycalesis gotama reared on KMD1 were not significantly different from those of the controls.

八、转Bt基因水稻对拟水狼蛛生长发育的影响取食在KMD1上饲养的褐飞虱若虫或稻眼蝶幼虫后，拟水狼蛛若蛛各龄的存活率与对照相比，无明显差异；六、七、八龄存活率和历期亦都无显著差异。

For example, in a study published last year in the Proceedings of the National Academy of Sciences a group of researchers looked at crustaceans (crabs, shrimps, woodlice and so on) over the past 550m years and found far more examples of groups of species evolving towards complexity than in the other direction.

举个例子，去年美国国家科学院公布的一项研究里，一群研究人员对生活在过去5.5亿年里的诸如螃蟹、虾、节肢动物有树虱之类的甲壳纲动物进行了研究。他们发现，更多的物种群体是朝着复杂而不是别的方向进化的。

Last year Joe Munyaneza, an entomologist at the Yakima Agricultural Research Laboratory in Washington state, found that tubers from plants exposed to these insects showed typical zebra-chip symptoms, while those from unexposed plants had none.

去年，华盛顿州雅基马农业研究实验室的昆虫学家乔·蒙耶尼沙发现，受木虱为害的马铃薯植株，块茎会出现典型的"斑马片"症状，而未受害植株，块茎没有这种症状。

The dominant species of pests is differential in the various seasons: Macrosiphum avenae and Rhophalsiphum padi is dominant species in spring, Delphacidae and Laphygma exigua is dominant species in summer, Helticus minutus and Acrididae is dominant species in autumn.

在害虫中，不同季节优势种不一样，春季的优势种是麦长管蚜和缢管蚜，夏季的优势种是灰飞虱和甜菜夜蛾，秋季的优势种是黑跳盲蝽和土蝗。
