摘要:
目的 探究榕透翅毒蛾对不同榕属植物的寄主偏好性和选择性,为榕透翅毒蛾的防治提供科学依据。 方法 以广州市4种榕透翅毒蛾寄主植物:黄金榕、高山榕、垂叶榕、小叶榕(雅榕)为对象,分析榕透翅毒蛾取食不同榕树叶片后的生长发育和摄食量等指标。 结果 不同榕树饲养的榕透翅毒蛾幼虫龄期存在差异,黄金榕5 ~ 7龄,高山榕和小叶榕6 ~ 8龄,垂叶榕6 ~ 9龄;垂叶榕饲养的榕透翅毒蛾幼虫发育历期最长,而黄金榕饲养的榕透翅毒蛾幼虫发育历期最短;在榕透翅毒蛾幼虫发育的每一龄级,以黄金榕饲养的榕透翅毒蛾幼虫体长、体质量和排泄物鲜质量最大;黄金榕饲养的榕透翅毒蛾幼虫2 ~ 7龄头壳宽最宽(1龄头壳高山榕最宽);黄金榕和高山榕饲养的榕透翅毒蛾幼虫存活率显著高于垂叶榕和小叶榕;幼虫取食黄金榕的榕透翅毒蛾雌成虫寿命最长,而取食高山榕的雄成虫寿命最长,雌成虫预卵期最短,单雌产卵量最多;1 ~ 4龄幼虫取食黄金榕的5龄幼虫更偏爱取食高山榕,而取食其他3种榕树的5龄幼虫寄主偏好性不明显。 结论 榕透翅毒蛾对4种榕树的偏好性和选择性存在显著的差异,其中黄金榕和高山榕比垂叶榕和小叶榕更适合榕透翅毒蛾幼虫生长发育。 Abstract:Objective To explore the host preference and selectivity of Perina nuda to different banyan species. Methods 4 species of host trees (Ficus macrocarpa, F. altissima, F. benjamina, and F. concinna) in Guangzhou were selected to feed on P. nuda and measure indicators such as their growth, development and food intake. Results The findings demonstrated that larval instar of P. nuda fed on 4 banyan species varied. During larval instar, P. nuda fed on F. microcarpa was 5th to 7th instar, P. nuda fed on F. altissima was 6th to 8th instar, and P. nuda fed on F. benjamina was 6th to 9th instar. This means that the development period of larval of P. nuda fed on F. benjamina was longest while the shortest period was the P. nuda fed on F. microcarpa. Additionally, body length, body weight and fecal weight of P. nuda larval fed on F. microcarpa were at the top among 4 banyan species. In the meanwhile, the 2nd to 7th instar larvae raised by F. microcarpa have the widest head capsule (the 1st instar larvae fed on F. altissima had the widest head capsule). Besides, the survival rates of P. nuda larvae reared by F. microcarpa and F. altissima were significantly higher than those of F. benjamina and F. concinna. Furthermore, the female adults of P. nuda larvae feeding on the F. microcarpa had the longest lifespan, while the male adults feeding on the F. altissima had the longest lifespan. It was also showed that the female adult had the shortest pre-ovulation period, and the single female laid the most eggs. Finally, it was found that the larvae fed on F. microcarpa at the 1st to 4th instars prefers to feed on F. altissima at the 5th instar, while the host preferences of 5th instar P. nuda larvae feeding on other three banyan species were not obvious. Conclusion There were significant differences in the selectivity and preference of P. nuda to 4 banyan species according to the results. Among them, the adaptability of P. nuda to F. microcarpa and F. altissima was strgonger than F. benjamina and F. concinna. -
