新型高效引诱剂实仓诱捕储粮害虫效果研究

EVALUATION OF TRAP EFFECTS OF A NEW ATTRACTANT ON STORED GRAIN INSECTS

按照特定的组分,利用食物中的挥发性物质的主要化学成分和几种主要储粮害虫的信息素成分进行混合,利用多孔淀粉进行包埋,制成的一种高效引诱剂。分别在山东省鲁北国家粮食储备库和广东省中山市储备粮管理有限公司,对这种高效引诱剂进行了实仓的诱捕效果研究。结果表明该引诱剂在山东鲁北库不仅可以有效预测到储粮书虱的发生,与传统的扦插取样检测相比,其诱捕的数量和实际发生程度一致;且可以预测出害虫发生的部位。在广东省中山市储备粮管理公司的实仓结果表明,与TraceR○翼型诱捕器及其配方的诱芯的诱捕效果相比,该引诱剂和自制诱捕器结合对储粮书虱具有显著的诱杀效果,最高每天诱捕到的数量为6500头书虱,并且发现诱捕器放在西北角和西南角时诱捕书虱的效果差异显著。

The high effective attractant was made with food volatiles and several stored product insects pheromone,which was microencapsuled by porous starch.The trapping effect on insects was studied in Lubei National Grain Storage Depot and Center Depot of Zhongshan Grain Reserve Management Ltd.respectively.The results showed that this attractant could effectively forecast occurrence of booklice population,and comparing with the traditional probe sampling,the insects numbers which trapped by the attractant coincided with the actual damage tendency of pests,furthermore,this attractant could also forecast the occurrence position of stored grain insects.In Center Depot of Zhongshan Grain Reserve Management Ltd.,the results showed that it had more significant trapping effect against booklice by combining the attractant with self-made trapper than the Moth patrol traps,the insects amounts trapped by the attractant were up to 6,500 heads of booklice,meanwhile,the field test also discovered that there were significant difference in trapping booklice between the south-west corner and north-west corner in the warehouse.
