( 5 ) 16 species of insects visited c. praecox in nanjing, belonging to hymenoptera, diptera, coleoptera, thysanoptera and spiders ( arachnoidea ) ; apis cerana cerana fabricius, aldrichina grahami ( aldrich ), epistrophe balteata de gee, musca hervei villeneuve are its main efficient pollinators
（ 5 ）南京地區蠟梅的訪問昆蟲約16種，分屬膜翅目hymenoptera 、雙翅目diptera 、鞘翅目coleoptera ，纓翅目thysanoptera 、及蛛形綱arachnoidea ，主要傳粉昆蟲有4種：膜翅目蜜蜂科東方蜜蜂中華亞種apisceranaceranafabricius 、雙翅目蠅科muscidae黑邊家蠅muscaherveivillcneuve 、麗蠅科calliphoridae巨尾阿麗蠅aldrichinagrahami （ aldrich ）及食蚜蠅科syrphidae黑帶食蚜蠅epistrophebalteatadegeer ；亮葉蠟梅的訪問昆蟲約18種，分屬鞘翅目coleoptera 、半翅目hemiptera 、纓翅目thysanoptera 、膜翅目hymenoptera 、雙翅目diptera 、鱗翅目lepidoptera ，另外有蛛形綱arachnoidea的蠟橄ch儷ononthuspr口ecox （ lIn this laboratory experiment green lacewing caterpillars proved more likely to die after eating european corn - borer caterpillars that had fed on bt corn instead of regular corn
研究是在實驗室中進行的，科學家以玉米螟幼蟲餵食蚜獅幼蟲，發現吃bt玉米長大的玉米螟會使蚜獅死亡，而普通玉米則否。The soil salification is a serious problem for agriculture and environment. especially now with the development of industry, the situation of soil salification becomes more and more serious, and the quality of water is continuous worsened. research on the mechanism of salt tolerance especially in the important crops, such as wheat, is becoming more urgent than ever before
土壤鹽漬化是影響農業生產和生態環境的嚴重問題，隨著工業污染加劇，灌溉用水的質量不斷下降和化肥使用不當等原因，次生鹽堿化土壤面積有不斷加劇的趨勢，給農業生產造成重大損失；黃矮病毒病是小麥等禾本科植物的重要病害之一，其傳毒介體蚜蟲更使植物產量損失巨大。The results show that the insect community in apricot tree stand have 6 orders, 25 families and 55 species, the dominant species concentrate on the group of scale insect, aphids, budworms and common lackey moth, gypsy moth
結果表明，杏樹林害蟲群落共有6目25科55種，優勢種集中於蚧蟲、蚜蟲、卷葉蛾等類群及天幕毛蟲、舞毒蛾等。They are harmful to agricultural plant. in the taxonomic study of aphidiodea insects, there are some questions about them. in order to clarify the arguments for the phylogenetic relationships of aphidinea insects, we determined a partial ( hoobp ) sequence of the 18s ribosomal dna for 13 aphid species ( 4 subfamilies, 6 families ) at the first time
例如，刺蚜亞科cervaphidinae屬于毛管蚜科greenideidae還屬于群蚜科thelaxidae ；粉毛蚜亞科pterocommatinae目前暫放在蚜科aphididae內，但無論從形態學還是生物學、寄主植物等方面該亞科與毛蚜科chaitophoridae有許多相似之處It is clear that pterocommatinae is closer to a. pisum
表明群蚜科與毛管蚜科近似。But there is ambiguously taxonomic position between chaitophoridae and aphidinae. the genetic distance of aphididae and macrosiphinae in aphididae is more diverged than that of between chaitophoridae and aphididae. the 600bp - 1700bp region of issrdna gene maybe unsuitable to aphididae, it includes a helix e21
1數據分析軟體中構建的upgma 、 nj 、 me和mp分子系統樹一致支持群蚜科和毛管蚜科形成一單系群，這二者相聚后與刺蚜亞科互為姐妹群。The average transition : transversion ratio was 1. 0 which indicated the genetic differentiation was great. the ration was 2 in nuclear dna gene. as a rule the ts : tv ratio decreased with the increasing genetic distance
1數據分析軟體，構建蚜總科蚜蟲分子系統樹，探討這些類群這間的分類地位和親緣關系，這在國內外尚屬首次。The respective outgroups acyrthosium pisum and lygus heperus knight are the new gene informations for the international biology gene bank. here we got the issrdna sequence data of the aphidiodea, which were firstly aligned by clustal w and then used to construct phylogenetic tree by mega 2. 1. the result of cervaphinae revealed that : ? he sequence included 797bp in length
本研究以越南、北京地區的蚜總科內代表蚜蟲為主要研究對象，在依據外部形態分類鑒定的基礎上，應用dna序列測定技術于蚜總科昆蟲系統學研究，通過pcr擴增獲得蚜蟲18srdna基因序列，應用clustalw程序進行同源對比，採用mega2分享友人
