Citrus huanglong is considered citrus is the most serious wood-destroying pests. this is a germ, citrus huanglong illness can be very kind of a citrus fruits and fruit trees lead to infection of the infection after a few years, the shrinking yellow and even death. the oranges wooden lice diaphorina citri kuwayama is a serious pest of orange, the citrus huanglong ill of the body. the main from the media。Asia a sour orange groves on the tick tend to produce a total of eight different wave, mainly from the prying into waves （ np wave ）, path wave （ pathway phase ） the part of a strong e1 泌 saliva wave （ wave ）, the department provided a passive 吸食 wave （ ） e2 waves and its part, "initiative 吸食 （ wave ）, in addition, found in other chest beak are the insects in his mouth off a wave of the d of the waves. d be a spy on the tick of citrus and a number of wave is related to the citrus wooden lice of spying on the wave。Was leaves leathery, did not affect the surface of the lice to plants and trees of the lice can still in 革质化 leaves for spying on the activities of a needle in a tick the surface of the time is no obvious difference.。The needle in a tick on the surface of the organization in which have thin wall of the organization organized for sites tend to impale the process of time to moderate the occurrence of serious and the occurrence of trees which have thin wall for spying on the wave （ path, c, the average time ） significantly, health, and with the occurrence of an extension。Are unwieldily flimsy is the organizational structure has changed significantly increase the tick of the meat in the leaves gave it food sites for the time required. the tick of the first to the skin of a strong 泌 saliva time and the first time in the department provided for 吸食 time with the occurrence of some level of increase significantly to the delay。A tick in the blades, the department was provided to the food is becoming increasingly difficult to tick in the gym. the leaves on very little in the wood, but was feeding on leaves yielding a tick in the proportion of the feeding and time marked increase in the late, the occurrence of wood is a tick. the main food。

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 caused by the infection within a few years after infection, yellow, shrink, or even death. Asian citrus psyllids Diaphorina citri Kuwayama is a serious citrus pests, spread of citrus Huanglongbing is the main transmission medium body.
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 citrus psylla population Screen related acupuncture probe wave, the Asian citrus psyllids specific probing wave.
Susceptible leathery leaf surface did not affect the fleas of the choice of the 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. Fleas into the leaf epidermis of acupuncture mouth parenchyma tissue in the puncture sites to find the process of feeding time spent in moderate and severe incidence of disease in plant parenchyma spy wave (path wave, C wave) the average time significantly longer than the healthy group, and with the increasing 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 in the xylem are few, but susceptible leaves fleas feeding in the xylem and the proportion of time a significant increase in incidence of late xylem is the main feeding psyllids site.

The harmfulness is regarded as the most serious illness offersorange pests. This is a bacterial disease, harmfulness can harm to all sorts of citrus fruit, fruit and cause infection in a few years after infection, atrophy, and even death yellow. Asia Diaphorina lema citrus citri Kuwayama is serious pest, citrus spread the harmfulness of main preach.
Wood lice in Asian orange orange leaf feeding of acid produced eight different waveform, mainly composed of spying on the wave (np), pathway (phase) path wave wave (E1 saliva secretion phloem phloem passive smoking wave), wave (E2) and xylem active snorting wave (G), in addition, also found in other chest beak mysticetes thorn attracts insects in the mouth of feeding wave wave. No D, D wave is orange wood lice mouth needle spying on the screen of the waveform is related to the wood lice unique Asian citrus spying waveform.
Feeling sick leaves leathery change does not affect surface of wood lice host plants, wood lice in mouth needle of blade leathery on spying activities, wood lice mouth needle leaf in the surface of the time stay no obvious difference. Wood lice needle leaf epidermis the mouth in the parenchyma organization for the process of feeding sites puncture in time in moderate and severe disease pathogenesis of spying on the waves were parenchyma, C (path) average time significantly longer health groups, and with the increase of the degree of disease and extension. Feeling sick leaves parenchyma structure change significantly increased wood lice in mouth needle biopsy found in the mesophyll feeding sites. Wood lice mouth needle first arrived phloem secretion and first time in salia suck time with continuous phloem significantly increased morbidity of backward delayed. Wood lice in feeling sick leaves phloem feeding became more and more difficult. Wood lice in rehabilitation leaves little in xylem on feeding, but in the sense of the disease in xylem in wood lice eat significantly increased the proportion of time, and the later is the primary xylem wood lice eat.
