【摘要】 使用GJ89型粮虫陷阱检测器对 11个浅圆仓储粮害虫发生特点进行初步调查。结果表明 ,在储藏期 3～ 5个月的散装小麦中共捕获 8种粮虫 ,普遍发生的害虫种类是书虱 (约占捕获害虫总量的 95 %～ 10 0 % ) ,谷蠹、玉米象、赤拟谷盗、锈赤扁谷盗等害虫亦有少量发生。钢屋盖浅圆仓较混凝土浅圆仓虫害发生严重 ,且仓壁四周书虱较中部多。粮面下 2m深度内虫害数量随粮层深度变化不明显更多还原

【Abstract】 The insect population distribution in two types of steel and concrete roof silos was surveyed by the use of GJ89 probe traps.8 insect species were captured in imported stored wheat mass after 3～5 months storage.The most dominant species was Liposcelis spp. accounting 95%～100% of total capture,while much fewer of Rhizopertha dominica,Sitophilus zeamais, Tribolium castaneum and Cryptolestes ferrugineus were found.The insect density occurred in steel roof silos was much higher than that in concrete roof silos.No difference was found among layers in two meters depth below wheat mass surface,but there was more insects appeared in the periphery position near the wall at the same level.更多还原
