葡萄阿小叶蝉成虫出蛰、越冬及田间分布规律

Post-Hibernantion, Overwintering and Spatial Distribution Pattern of Arboridia kakogawana Adult(Hemiptera:Cicadellidae)

  • 摘要: 为明确葡萄阿小叶蝉成虫出蛰、越冬及田间分布规律,2019年利用黄色黏虫板,结合葡萄园气象数据对其进行了系统调查与分析。结果表明,在宁夏贺兰山东麓地区,葡萄阿小叶蝉越冬代成虫3月中旬在田间开始活动,11月中旬末完全进入越冬状态,其出蛰与日平均气温呈高度正相关,当连续7 d平均气温稳定在8.0℃以上时,越冬代成虫逐渐离开越冬场所,开始在田间活动;其越冬与日平均气温、日平均最低气温和日平均最高气温呈极显著正相关,当日平均气温低于4℃,日最高气温低于10℃,且日最低气温低于-3℃时,成虫开始进入越冬状态;各代成虫在葡萄园田间的分布呈从靠近林带的边行往田间深处虫口数量渐少的趋势。

     

    Abstract: In order to clarify the post-hibernantion, overwintering and spatial distribution pattern of Arboridia kakogawana adult, systematic investigation and analysis were carried out in 2019 using yellow sticky trap combined with local meteorological data. The results showed that A. kakogawana overwintering adults began to move in middle March, and went into overwintering at the end of mid November in the eastern foothills region of Helan Mountain in Ningxia. The post-hibernant of A. kakogawana overwintering adults was positively related to daily average temperature, and left overwintering site and started activity in the field when the average temperature stay above 8.0 ℃ for seven days. The overwintering of A. kakogawana was significantly related to daily average temperature, daily average minimum temperature, and daily average maximum temperature. A. kakogawana overwintering adults entered overwintering state when the daily average temperature and the daily average maximum temperature was of below 4 ℃ and 10 ℃, respectively, Moreover, the daily average minimum temperature was of below about-3 ℃. The population distribution of adults in each generation showed a gradual decrease from the edge row near the forest belt to field in the vineyard.
