Effect of Atmospheric Pollution on Phytophagous Insects and Its Mechanism. 大氣汙染對(duì)植食崑蟲(chóng)的影響及作用機(jī)制。
The species number of phytophagous,predatory,parasitic and spider groups was 30,8,10 and 20 respectively. 植食性、捕食性、寄生性崑蟲(chóng)和蜘蛛的物種數(shù)分別爲(wèi)30、8、10和20。
In addition, the plant reduces speaking of these phytophagous animal also lacks food origin. 此外，植物減少對(duì)那些食草類(lèi)動(dòng)物而言也缺少食物來(lái)源。
There are lots of factors causing infestation of phytophagous pests and changes of dominate species in the apple orchards. 摘要蘋(píng)果園內(nèi)植食性崑蟲(chóng)種群數(shù)量的上陞和主要種類(lèi)的變替，原因是多方麪的。
The larva and diet of phytophagous coccinellids indicate that that they are the most ancestral group of Coccinellidae evolving from ancestors like chrysomelids. 無(wú)論從幼蟲(chóng)形態(tài)還是食性來(lái)看,植食性瓢蟲(chóng)都是瓢蟲(chóng)科最原始的類(lèi)群,有可能最早從葉甲類(lèi)崑蟲(chóng)進(jìn)化而來(lái)。
Transgenic insect-resistance hybrid poplar 741 had negative effect on target and non-target phytophagous pests, but had positive effect on natural enemies and neutral arthropod. 研究表明，轉(zhuǎn)基因741楊對(duì)目標(biāo)崑蟲(chóng)和非目的植食性害蟲(chóng)存在負(fù)傚應(yīng)，而對(duì)天敵和中性節(jié)肢動(dòng)物組成和發(fā)生無(wú)明顯負(fù)作用。
