| 摘要: |
| 为了有效控制茶翅蝽对果实产生的严重为害,分别在室内、外不同条件下,以声、光干扰方法研究该虫行为变化及其防制途径。结果表明,饥饿12 h的茶翅蝽蛰后对食物反应敏感;触角是嗅食、确定食物方位的主要器官;在10 cm范围内视觉对食物形状及取食位点产生作用;桃、梨、苹果的果实为其最喜食物;取食过程分寻找、定位、刺入、取食、结束和离去6个阶段;成虫取食、爬行与飞翔等行为受气温变化影响明显,25 ℃以上时行为敏捷;触角间夹角与温度上升呈显著正相关,在5～35 ℃范围内变幅为45°～150°;气温<23 ℃时初显假死行为,然后随温度渐降而加深;突然的声、光干扰能使其假死坠落,假死深度与气温下降和干扰源功率呈正相关。选择气温<21 ℃的适宜日时段,以棒击震树落虫,地面喷药触杀,可取得高效、安全的防治效果,且单株药物用量较常规药量降低88.4%。 |

| Halyomorpha halys behaviors and their application for control |
|
|
| Abstract: |
| Halyomorpha halys was a chief fruit pest in orchard,so its behaviors and utilizing for control were studied by combining field investigation and experiment.The results show that after 12 hours' hungry treatment,the imagoes show sensitive reaction to food after hibernation.Antennas are the major organs to sense food and vision works within 10cm to food.Imagoes are significantly selective to food.Peach,pear,and apple are their favorite.Selecting eating place,fixing position,piercing into food,taking in food,finishing eating and taking leaves are their major eating behaviors.The behavior of Halyomorpha halys in terms of eating,crawling and flying varies with the weather temperature.When temperature is above 25℃,its behavior is swift,and the antenna angle shows positive correlation with temperature,and the angle varis within 45°-150°with temperature ranging from 5℃ to 35℃.When below 23℃,anabiosis appears and deepens with the decrease of temperature.Sudden disturbance from noise or light causes anabiosis in the form of dropping down.The depths of anabiosis are associated with then temperature and disturbance power.Field tests showed that at suitable temperature (<21℃) with appropriate period of time,stick beating can lead Halyomorpha halys to anabiosis and dropping to the ground,followed by spraying pesticides,which would be safe and the dose per plant will reduce 88.4%. |
