- 摘要:
- 为了确定哈尔滨地区韭蛆的最佳防治时期、方法及部位,以越冬韭墩为研究对象,采用室内及室外盆栽饲养技术,对韭蛆发生规律进行调查分析。结果表明:哈尔滨露地、保护地韭蛆一年发生3代,以一代幼虫危害最为严重,露地发生在5月中旬,保护地发生在5月初;越冬虫态发育起始温度为16℃;成虫活跃在土壤表面高度10 cm空间,幼虫活跃在土表2 cm根际。
- Abstract:
- In order to determine the optimal control period,method and control part of Bradysia odoriphaga in Harbin area,taking winter leek pier as the research object,potted breeding technology indoor and outdoor was adopted to investigate the occurrence regularity.The results showed that three generations of Bradysia odoriphaga happened every year outdoor and in protection area,the damage of first generation larvae was the most serious.It occurred in mid May and early May in protection;Initial temperature of overwintering stages was 16℃;Adults were activing in the space of surface soil for 10 cm,larvas were activing in soil rhizosphere for 2 cm.
