| 摘要 | [Objective] The paper was to investigate the artificial rearing of Pagiophloeus tsushimanus larvae and to propose a novel approach for addressing the challenges associated with test insects for pest research experiments. [Method] A study was conducted to investigate the effects of three semi-artificial diets on the rearing of P. tsushimanus larvae. [Result] The study revealed significant differences in the fitness performance of P. tsushimanus larvae reared on three distinct semi-artificial diets. Notably, larvae that were fed semi-artificial diets formulated from their natural host plant, Cinnamomum camphora, exhibited superior growth and developmental performance. In contrast, P. tsushimanus larvae that were provided with semi-artificial diets derived from Cinnamomum chekiangense and Phoebe chekiangensis, which are closely related species, demonstrated marked fitness costs. These costs were evidenced by a significant prolongation of the larval developmental duration, a substantial decrease in body weight and average daily weight gain, as well as a notable reduction in survival rate, pupation rate, and emergence rate. [Conclusion] Semi-artificial diets derived from the natural host plant, C. camphora, represent the most effective dietary regimen for the indoor rearing of P. tsushimanus larvae. This approach not only ensures a sufficient supply of test insects but also serves as a viable rearing method for research focused on the integrated prevention and control of P. tsushimanus. |
