柑桔木虱在健康和黄龙病柑桔树上的刺探电位图谱比较
柑桔黄龙病被视为柑桔害虫病里最严重的。这是一种细菌病，柑桔黄龙病可以危害到各种柑橘类水果，并且导致受感染果树在感染后几年内枯黄，萎缩，甚至死亡。亚洲柑桔木虱Diaphorina citri Kuwayama 隶同翅目Homoptera 木虱科Psyllidae，柑桔木虱是严重的柑橘害虫，也是传播柑桔黄龙病的主要传媒介体。
亚洲柑桔木虱属植食性刺吸式口器昆虫，其传毒方式与取食行为密切相关。本实验研究了柑桔木虱在健康和黄龙病柑橘树上的取食行为差异，以EPG（electrical penetration graph）技术为主，自由状态下的刺吸取食行为为辅，以刺探电位图谱为取食行为比较提供依据。
亚洲柑桔木虱在酸桔叶片上取食共产生8种不同的波形，主要由非刺探波（np波）、路径波（pathway phase）韧皮部分泌唾液波（E1波）、韧皮部被动吸食波（E2波）以及木质部主动吸食波（G波），此外，还发现在其他胸喙亚目刺吸式口器昆虫取食波中没有的D波，D波是柑桔木虱口针刺探筛管相关的波形，是亚洲柑桔木虱特有的刺探波形。
感病叶片表面革质化并未影响木虱对寄主植物的选择，木虱口针仍然能够在革质化的叶片上进行刺探活动，木虱口针在叶片表面停留的时间没有明显差异。
木虱口针刺入叶片表皮组织在薄壁组织组织穿刺寻找取食位点的过程中所用时间在中度发病和严重发病植株薄壁组织中的刺探波（路径波，C波）平均时间都显著长于健康组，并且随发病程度的增加而延长。
感病叶片薄壁组织结构的改变显著增加了木虱口针在叶肉组织中穿刺寻取食位点所需要的时间。
木虱口针首次到达韧皮部分泌唾液时间点和首次在韧皮部持续吸食时间点随发病程度的增加显著向后延迟。
木虱在感病叶片韧皮部取食变得越来越困难。
木虱在健树叶片上很少在木质部中取食，但在感病叶片上木虱在木质部中取食的比例和时间显著增加，发病后期木质部是木虱主要的取食部位。
Citrus wood lice in health and disease citrus trees spying huanglong. Potential map

Citrus psyllids in health and disease of citrus trees, spying Huanglong potential comparative map of Citrus Citrus Huanglongbing be regarded as the most serious pest disease. This is a bacterial disease, citrus Huanglongbing could jeopardize a variety of citrus fruits and fruit trees leading to infection within a few years after infection, yellow, shrink, or even death. Asian citrus psyllids Diaphorina citri Kuwayama attached Homoptera Homoptera psyllids families Psyllidae, citrus psylla is a serious citrus pest is primarily spread of citrus Huanglongbing body mass media. Asian citrus psyllids are phytophagous piercing-sucking mouthparts of insects, poisonous way of its transmission is closely related to feeding behavior. In this study, citrus psylla in citrus tree health and Huanglongbing different feeding behavior to EPG (electrical penetration graph) technology-based, free state, the probing and feeding behavior, giving the map to get to spy on potential eating behavior provide the basis for comparison. Asian citrus psyllids in the sour orange leaves on feeding produced a total of 8 different waveforms, mainly by non-probing wave (np wave), the path wave (pathway phase) wave phloem salivation (E1 wave), phloem passive smoking wave ( E2 wave) and the xylem active smoking wave (G wave), was also found in other breast Hui suborder wave piercing-sucking mouthparts insect feeding is not the D wave, D wave is the population of citrus psylla Screen needle probe related waveform, is unique to spy on Asian citrus psyllids waveform. Susceptible leathery leaf surface did not affect the fleas of the choice of host plants, psyllids stylet still in the leather quality of the leaves on espionage, Psylla stylet stay in the leaf surface, no significant difference in time. Psylla mouth into the leaf epidermis of acupuncture in the parenchyma tissue biopsy to find feeding sites during the time spent in moderate and severe disease onset in plant parenchyma spy wave (path wave, C wave) the average time significantly longer than the healthy group and increased with the degree of extension of disease. Susceptible to change the structure of leaf parenchyma significantly increased fleas stylet puncture in the mesophyll tissue feeding sites to find the time required. Sucker stylet to reach the first phloem salivation time point and for the first time in the phloem continued taking time with the disease severity increased significantly backward delay. Psyllids in susceptible leaf phloem feeding has become increasingly difficult. Psyllids in healthy leaf feeding is rarely in the xylem, but in susceptible leaves fleas feeding in the proportion of xylem and time in a significant increase in incidence of late xylem is the main feeding psyllids site.
