蚜虫

Access to a large number of Chinese and foreign literatures, this text summarized the life cycle of aphids including anholocyclic type, heteroecious holocyclic type and antoecious holocyclic type, and the important biological characteristics including alternation of generations, difference of hibernation and polymorphism, it offered the theory basic of comprehensive prevention and control.

通过查阅大量的中外文献，对蚜虫生活周期的不全周期生活史、全周期同寄主生活史和全周期异寄主生活史进行了阐述，归纳出蚜虫生活周期中的世代交替、越冬方式的差异、多型现象几个主要生物学特点，为蚜虫的科学控制提供一定的参考价值。

Uses: A selective aphicide used in cereals, fruit, ornamentals, strawberries, potatoes, sugar beet, fodder beet, cotton, oilseed rape, tobacco, and glasshouse crops, effective against organophosphorus-resistant Myzus persicae . Phytotoxicity: Compatibility

抗蚜威对瓢虫、食蚜蝇、蚜茧蜂等蚜虫天敌没有不良影响，因保护了天敌，而可有效地延长对蚜虫的控制期，抗蚜威对蜜蜂安全，用于防治大白菜、萝卜等蔬菜制种田的蚜虫时，可提高蜜蜂授粉率，增加产量。

After the examination of time-intervals for treatment, three days should be the proper time-interval between treatments in order to annihilate aphides thoroughly.

通过不同时间间隔灭杀蚜虫的效果比较，发现3d后再次进行灭蚜处理，能够达到彻底消灭蚜虫的目的。

By comparison among different methods, it was found that arrest-board together with drug insufflation application was an effective method for prevent and cure aphides indoors.

使用捕虫板法、喷洒药物法和综合法对蚜虫进行防治，通过效果比较，发现综合法是培养室内拟南芥蚜虫防治的理想方法。

Beta frequently used as rootstock in China was susceptible to phylloxera. Phylloxera survived at 38.82%~47.5% and produced 9.01 eggs per day on Beta, while the corresponding values were 25%~30% on concord and compbell and 6.00~6.85 eggs per day on concord, campbell and catawba. Both Hei Huxiang and White Banana of Vitis vinifera-V. amerancain were susceptible to phylloxera, on which phylloxera yielded more than 190 eggs totally despite their survival was down-regulated and development arrested to some extent. All V. vinifera and cross cultivars of V. vinifera-V.

我国当作砧木使用的贝达不抗根瘤蚜，接种后蚜虫存活率始终保持在38.82%~47.5%，日产卵量达9.01；欧美杂交种中的康克、康拜尔和卡它巴对根瘤蚜稍有抗性，根瘤蚜日产卵量在6.00~6.85粒之间，其中康克、康拜尔葡萄上蚜虫的存活率随时间的延长而明显降低，由最初的60%下降至25%~30%；欧美杂交种中的黑虎香和白香蕉虽然在一定程度上能够限制根瘤蚜的存活和发育进程，但对根瘤蚜的繁殖量没有影响。

Chrysopa septempunctata was fed with two foodstuffs, aphids and artificial ovum Trichogramma's pupas. The results indicated that survival time of female worms which intook aphids was obviously longer compared with those which intook artificial ovum Trichogramma's pupas, and their ovum quantity obviously rose. But artificial ovum Trichogramma's pupas can be used as supplementary foodstuff to raise green lacewing because of its factory production.

用蚜虫和人工卵赤眼蜂蛹两种食料来饲养大草蛉的结果表明，喂食蚜虫的大草蛉雌成虫存活时间明显长于喂食人工卵赤眼蜂蛹的大草蛉，产卵量亦明显提高，但人工卵赤眼蜂蛹已经实现了工厂化生产，可以作为饲养草蛉的补充食料。

Aphids in the process of inhaling plant sap virus particles and auxiliary proteins also be inhaled, thus completing the process by poison, which also supports the field citrus aphid is non-persistent decline disease vector of disease, while the citrus Huanglongbing is phloem restricted by the bacteria caused the main pathogens present in the phloem, the fleas only by phloem feeding in diseased plants, pathogens in the body through the back to complete the salivary glands in the course of the next through the sieve tube feeding in the secretion of saliva the pathogens into the healthy tree, Citrus Huanglongbing different characteristics with aphid-borne diseases, Huanglongbing to persistent disease.

蚜虫在吸入植物汁液的过程中病毒粒子和辅蛋白同时也被吸入，从而完成获毒过程，这也支持了田间蚜虫是柑桔衰退病等非持久性病害传播介体，而柑桔黄龙病是由韧皮部限制性细菌类引起，病原体主要存在于韧皮部中，木虱只有通过在病株韧皮部取食，病原在体内完成循回到唾液腺中，在下一次取食过程中通过在筛管中分泌的唾液将病原体带到健树，柑桔黄龙病与蚜虫传病特点不同，黄龙病为持久性病害。

In order to clear the aphid and Citrus tristeza disease epidemiology, in this research, to determine the dominant stocks of aphid on citrus by investgatting the occurrence and the damage of the aphids; to clear the relation of aphids and citrus tristeza disease epidemic by analysissing the identity and the efficiency of T.

为了解蚜虫与CTV流行的关系，本试验通过调查柑桔蚜虫的发生与为害，明确柑桔蚜虫的优势种群；就橘蚜传播柑桔衰退病的传毒特性、传毒率、影响传毒率因素等的分析，明确蚜虫在柑桔衰退病流行中的作用；以及对带毒橘蚜体内的CTV分子生物学检测。

So we conclude that phylogenetic relationships between different aphids and their endosymbiotic bacterium Buchnera may be different, and this conclusion is accordant with previous study. This work not only fill a gap on phylogenetic relationships between the three aphids, M.

这一工作不仅弥补了这三种蚜虫与其内共生菌Buchnera之间的进化关系空白，同时有助于我们在了解这些蚜虫Buchnera的系统进化特征的基础上，进一步全面地了解了这三种蚜虫的内共生菌Buchnera。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
