摘要: 为探究点蜂缘蝽(Riptortus pedestris)越冬虫态及其耐寒性,通过调查野外越冬种群、模拟越冬试验及成虫温度依赖性存活试验,分析点蜂缘蝽在黄淮海地区越冬的可能性及其相应的越冬虫态,并通过过冷却点测定仪,测定各虫态点蜂缘蝽的过冷却点和结冰点。结果表明:在黄淮海地区,进入冬季后,点蜂缘蝽的成虫及其卵的存活时间较长,可能为点蜂缘蝽的越冬虫态,卵因孵化条件以及寄主物取食,无法孵化,表明点蜂缘蝽在黄淮海地区以成虫越过完整冬季,成虫占比是20.4%;点蜂缘蝽野外成虫种群比室内成虫种群越冬存活率高,越冬存活率为23.33%;模拟点蜂缘蝽成虫温度依赖性存活试验的存活率与越冬试验的存活率相互吻合;点蜂缘蝽成虫的过冷却点和结冰点比其他虫态较低,分别为-17.61℃和-8.59℃。研究发现,点蜂缘蝽具有耐寒性及低温存活能力,野外种群成虫和室内种群成虫都能安全越冬,黄淮海地区及相近等温带可能成为点蜂缘蝽的冬繁区。研究初步探明了点蜂缘蝽的越冬规律和耐寒性,以期为黄淮海地区点蜂缘蝽预测预报体系构建,以及长效治理策略规划提供参考。

Abstract:

In order to explore the overwintering stages and cold tolerance of Riptortus pedestris, the possibility of its overwintering in Huang-Huai-Hai Region and the corresponding overwintering stages were analyzed through field investigations of wild overwintering populations, simulated overwintering experiments and adult temperature-dependent survival experiments. Additionally, the supercooling points and freezing points of Riptortus pedestris in different stages were determined by a supercooling point measuring instrument. The results showed that adults of Riptortus pedestris and their eggs lived longer after entering winter in Huang-Huai-Hai Region, which may be the overwintering state of. Eggs cannot survive due to hatching conditions and host feeding, indicating that Riptortus pedestris crossed the whole winter in Huang-Huai-Hai Region in adult stage, and the proportion of adults was 20.4 %. The survival rate of adult Riptortus pedestris in the field was higher than that in indoor, with the survival rate of 23.33%. The survival rates of the simulated temperature-dependent survival experiment on adult Riptortus pedestris were in good agreement with those of the overwintering experiment. The supercooling point and freezing point of adult Riptortus pedestris are lower than other patterns, which are -17.61℃ and -8.59℃ respectively, indicating that Riptortus pedestris has cold hardiness and low temperature survival ability. The Huang-Huai-Hai Region and other temperate zones may be the winter breeding area of Riptortus pedestris.
