绵蚜

Among the most destructive enemies of the apple orchard are the codling moth, various species of mites, the woolly aphid, the apple maggot, the red-banded leaf roller, and scale insects.

庄稼损伤在苹果树的最破坏性的敌人之中是小蜘蛛的苹果蠹蛾、各种各样的种类，绵蚜、苹果蛆、红色被结合的卷叶蛾和介壳虫。

Sugarcane stem borer and Ceratovacuna lanigera Zehnther are the main pests of sugarcane, which not only make sugarcane yields loss but also make sucrose content decline.

蔗螟和绵蚜是甘蔗的重要害虫，它们不但造成甘蔗产量损失、蔗糖含量的下降，还传播多种甘蔗病毒，传病造成的损失比直接为害造成的损失更为严重。

Host alterations of the root aphid, Tetraneura nigriabdominalis, among four host plants ( Eleusine indica , Oryza sativa , Zea mays , and Sorghum bicolor ) were studied by comparing adult longevity, fecundity, and population parameters in the laboratory.

於实验室中，研究粗长毛禾根绵蚜 Tetraneura nigriabdominalis (Sasaki 在四种寄主植物(牛筋草 Eleusine indica 、水稻 Oryza sativa 、玉米 Zea mays 及高粱 Sorghum bicolor )转移对其成蚜寿命、繁殖率及族群介量之影响。

Harmonias axyridis is one of important predatory natural insect for controlling Eriosoma lanigerum in apple orchards.

异色瓢虫是苹果绵蚜的主要捕食性天敌昆虫，其在苹果园的初发期在2~3月，高峰期在3~4月。

To study the interaction between Eriosoma lanigerum and apple trees, olfactory response of the aphid to different kinds of apple branches was tested by Y-olfactometer and volatiles from the branches were extracted with HS and measured with GC-MS. The result showed that E.

为探讨苹果绵蚜与苹果树的互作关系，用Y形嗅觉仪测试该虫对不同苹果品种枝条的嗅觉反应，顶空萃取枝条挥发物，并进行GC-MS分析。

In addition to the capacity of transmission SCYLV between sugarcane plants efficiently, 100%(9/9), 75%(6/8), and 50%(4/8) respectively while 15 viruliferous aphids were inoculated for each plant.

建立了能够检出单头蚜虫及侵染早期未现症植株体内SCYLV的巢式RT-PCR技术，在超过80%的饲毒2周以上的甘蔗绵蚜无翅成虫体内检测到病毒的存在。

A nested-RT-PCR technique was established for SCYLV detection from individual viruliferous aphids and plant in early stage of infection, about 80% adult aphids feeding on sugarcane plants with yellow leaf symptom for over 2 weeks showed SCYLV positive by this technique.

但广州甘蔗研究所品种基地源自美国运河点育种场的CP93-1319病株上的病毒与已报道的三个基因型存在较大差异，可能代表了SCYLV的一个新的基因型。本文首次证实华南地区甘蔗上普遍发生的甘蔗绵蚜为SCYLV传毒媒介。

The results showed that the wolly apple aphid distributed in Linfen, Yuncheng ,Changzhi and Jinzhong Prefecture.

通过对4区9地的调查结果表明：苹果绵蚜已经入侵到临汾市、运城市、长治市和晋中市。

Aiming at the biological character,morphological character and harm regulation of Woolly apple aphid,the article summarizes four effective measures to control harm occurrence,and this provided references for apple production.

通过分析苹果绵蚜的生物学特性、形态特性和危害规律，总结出4条有效防控措施，为苹果生产提供了借鉴。

Formic acid, hexyl ester and Z-3-Hexen-1-ol were preliminarily confirmed to be the important substances for attracting woolly apple aphid, but 4-methyl-1, 3-pentadiene and Z-3-hexen-1-ol, acetate were not.

初步确定，E-3-己烯－1-醇、甲酸己酯可能是对苹果绵蚜有较强引诱作用的重要物质；4-甲基－1，3-戊二烯、乙酸叶醇酯不是引诱苹果绵蚜的物质。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
