Abstract

Pomacea canaliculata (Lamarck 1822), a freshwater gastropod indigenous to lower Del Plata Basin of Argentina, has become the most destructive and invasive rice pests in south China since its introduction in the 1980s. In Guangdong, the main production areas for double rice, most of P. canaliculata overwinter in paddy field ditches after late-rice harvesting in mid-November and diapause to temporarily to avoid the damaging effects of extreme low temperatures. This pest aroused from diapause and migrated to the paddy field after early-rice reviving in next late March. Overwintering and cold tolerance of natural P. canaliculata have a non-negligible impact on population dynamics and distribution in the following year. We tested the supercooling capability, levels of cryoprotectant synthesis, activity of antioxidant defense system (antioxidant enzymes and reduced glutathione), and degree of oxidative damage (concentration of malondialdehyde as an index of lipid peroxidation) monthly, using natural P. canaliculata samples with a size-gender structure (i.e., juveniles, female, and male adults) from experimental ponds during the period of mid-November to the following April. P. canaliculata survived the winter with a monthly death rate of 7%-16.5% in coldest January. The supercooling point (SCP) of overwintering P. canaliculata decreased initially before increasing subsequently with monthly changes in water temperature. P. canaliculata accumulated a high glycogen content before December, which depleted towards the end of January, while lipid content reached peak in January and depleted since February. Activity of antioxidant defense system of P. canaliculata exhibited significant monthly differences and showed relatively higher size heterogeneity than monthly variations. The results contribute to the knowledge of adaptability in overwintering P. canaliculata and help to understand the mechanism of the invasive success of this species.

华南地区自然越冬红豆杉的耐寒性和生理反应
Pomacea canaliculata(Lamarck 1822)是一种原产于阿根廷德尔普拉塔盆地下游的淡水腹足类动物,自上世纪80年代传入中国以来,已成为华南地区最具破坏性和入侵性的水稻害虫。在双季稻主产区广东,11 月中旬晚稻收割后,大部分 P. canaliculata 在稻田沟渠中越冬,暂时休眠以躲避极端低温的危害。翌年 3 月下旬早稻收割后,该害虫从休眠状态苏醒并迁入稻田。天然 P. canaliculata 的越冬和耐寒性对翌年的种群动态和分布有着不可忽视的影响。我们在 11 月中旬至翌年 4 月期间,使用来自实验池塘的具有大小-性别结构(即幼体、雌性和雄性成体)的天然 P. canaliculata 样品,每月测试其过冷能力、低温保护剂合成水平、抗氧化防御系统(抗氧化酶和还原型谷胱甘肽)活性和氧化损伤程度(丙二醛浓度作为脂质过氧化指数)。在最冷的 1 月份,P. canaliculata 的月死亡率为 7%-16.5%。越冬金鱼的过冷点(SCP)最初下降,随后随着水温的每月变化而上升。金鱼藻在 12 月前积累了较高的糖原含量,并在 1 月底消耗殆尽;脂质含量在 1 月达到峰值,并从 2 月开始消耗殆尽。金枪鱼抗氧化防御系统的活性表现出显著的月度差异,其大小异质性相对高于月度变化。这些结果有助于了解越冬金针菜的适应性,并有助于理解该物种成功入侵的机制。
