Abstract:
[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.
