| 摘 要： | 调查了河北省馆陶县农田蜗牛发生危害特点。河北省馆陶县多年来农作物受蜗牛危害，发生程度有逐年加重趋势；发生范围呈局部区域分布，且局部区域面积不断扩大；受危害作物的种类较多，以夏玉米、棉花、白菜等受害最重，危害玉米可造成叶片撕裂，雌穗秃尖和籽粒不饱满，严重影响产量；棉花造成蕾铃脱落，白菜造成花叶，商品性降低；受害田虫口密度不断增加．玉米田一般百株虫量50～80头，严重地央300～500头，最高可达1000-2000头。其发生轻重与温度、降水有关，月平均温度在19～25℃最适宜，与7、8月份降水呈正相关。活动规律白天隐蔽，傍晚或阳光较弱时活动，防治时机较短；且身上有外壳保护，给防治带来困难。夏玉米后期发生严重，为提高防效，最好防治时间提前，采取物理、农业和化学综合防治措施进行防治。在玉米苗期撒施毒饵，如果错过时机，后期可以先振落再撒毒饵防治。

| Abstract: | The harm of cropland snail in Guantao County of Hebei Province was investigated. Snails happened badly in local region of Guan County in recent years, and their hazard area was growing year by year. They could cause leaf-tom, barren ear tip, hollow kernels and low yields of maize, abscission of cotton buds and bolls, mosaic disease of Chinese cab- bage. The population density in maize fields was 50-80 insects/100 plants, seri- ous fields could be 300-500 insects/100 plants, and could reach 1 000-2 000 in- sects/100 plants at the most. Snail occur- rence had a positive relationship with precipitation of July and August. Month- ly average temperature of 19-25~C was also appropriate for their occurrence. Snails hid in daytime and came out in the evening, so the control time was short. The snail shells also brought difficulties to control. They happened badly in later period of summer maize, so we should bring ahead control time and take chemical, physical and agriculture measurements. Poison bait could was scattered in the fields in maize seedling period. If season was missed, it could be done after shaking offpalnts. |
