中文摘要：【目的】 研究柑橘木虱Diaphorina citri Kuwayama在柚、酸橘、黄皮、九里香、砂糖橘5种代表性芸香科寄主植物上的发育、存活和繁殖情况，为柑橘木虱及黄龙病的可持续防控提供参考。【方法】 利用种群生命表的方法，分析了柑橘木虱在5种不同寄主植物上的发育历期、存活率、成虫寿命、性比及产卵量等数据。【结果】 柑橘木虱卵、1龄若虫以及整个若虫的发育历期受寄主植物的影响较为明显，在26
℃条件下在柚子植物上柑橘木虱若虫的存活率最高（58.10%），在黄皮上最低（46.04%），两者差异显著。寄主植物影响柑橘木虱成虫寿命，在柚子上柑橘木虱成虫的寿命显著长于黄皮上的寿命。黄皮上的柑橘木虱的单雌产卵量（298粒/雌）显著低于其他4种寄主植物。柑橘木虱在九里香上的内禀增长率（rm）最高（0.133 7）、酸橘上最低（0.129 8）；而净增值率（R0）在砂糖橘上最高（187.74）、黄皮上最低（145.27）。【结论】 在5种寄主植物中，除黄龙病隐症寄主九里香之外，显症寄主中砂糖橘是柑橘木虱的最适寄主。
英文摘要：
[Objectives] To
investigate the life history of the Asian citrus psyllid (ACP) Diaphorina citri on five different host
plants, Citrus maxima, Citrus ‘Suanju’, Clausena
lansium, Murraya exotica L. and Citrus flamea Hort. ex Tseng shiyueju. [Methods] The developmental period, juvenile survival
rate, and adult longevity, sex ratio and fecundity, were measured and compared
based on an experimental life table. [Results] The developmental
duration of eggs, 1st instar larvae and the complete larval stage
differed significantly on the five host plants. The survivorship of immatures
was highest (58.10%) on C. maxima and lowest on C. lansium (46.04%). Adult
longevity was significantly affected by host plants and was highest on C. maxima and shortest on C. lansium. The average fecundity of
adult females on C. lansium was 298
eggs/female, which was distinctly lower than on the other four plant species.
The intrinsic rate of increase (rm) was highest on M. exotica (0.133 7) and lowest on the Citrus
‘Suanju’ (0.129 8). The net reproductive rate (R0), was
highest on Citrus flamea Hort.
ex Tseng shiyueju (187.74) and lowest
on C. lansium (145.27). [Conclusion] Our results indicate that, in addition to M.
exotica, Citrus flamea Hort. ex Tseng shiyueju is a
relatively suitable host plant for the ACP.
