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.
