摘要
用2种方法测定了柑橘木虱Diaphorina citri Kuw.成虫对13个柑橘品种离体嫩梢的选择性。结果表明,对不同品种进行两两组合的选择性试验,柑橘木虱停靠在处理组合早金和四季斑叶橘的虫量占总虫量的23%和1%,停靠在处理组合台湾玫瑰橙和纽荷尔脐橙上的虫量分别占总虫量的33%和20%,停靠在处理组合日辉和佩奇甜橙上虫量分别占总虫量的38%和15%,两两之间差异显著。将13个品种组合在一起进行选择性试验,结果表明柑橘木虱停靠在纽荷尔、福橘和佩奇甜橙上的成虫数量为每梢3.2-6.6只.d-1,显著高于木虱在其余10个品种枝梢上的停靠数量。福橘是柑橘黄龙病高发品种的原因是其对柑橘木虱的吸引力较强。
Under laboratory conditions,preference of adult Asian Citrus Psyllid（ACP）,Diaphorina citri Kuw,for infestation among 13 citrus varieties was determined with two experimentations.Experiment A applied every 2 detached shoots of different citrus varieties and put together for choice.Experiment B used the detached shoots of all tested citrus varieties and put together for choice.The results of Experiment A revealed that the percentage of ACP adults on each shoot of Citrus sinensis（L.） Osbeck cv.Earlygold and C.medurensis（C.mitis） cv.Varigated Calamondin were 23% and 1%,respectively,which was significantly different from each other.The percentage on C.sinensis Osbeck cv.Taiwanmeiguicheng（33%） and cv.Newhall Navel Orange（20%） were also significantly different from each other.Significant different percentages of ACP adults were also observed between C.reticulata C.paradisi cv.Rihui（38%） and C.reticulata C.grandis cv.Page（15%）.In Experiment B,the number of ACP on the shoots of C.sinensis Osbeck cv.Newhall Navel Orange,C.tangerina Tanaka cv.Fuju and C.reticulata Citrusgrandis cv.Page was 3.2-6.6 adults·shoot-day-1,which were significantly higher than that on the shoots of the other 10 citrus varieties.
