摘　　要：研究了不同饥饿条件下6种重要储粮害虫赤拟谷盗、锯谷盗、锈赤扁谷盗、米象、谷蠹和烟草甲成虫的耐饥饿能力。研究结果表明,对于羽化后1周龄的6种储粮害虫成虫,赤拟谷盗和烟草甲成虫耐饥饿能力较强,耐饥饿时间可达到30 d以上,其次为锯谷盗、锈赤扁谷盗和谷蠹成虫,耐饥饿时间可达到15 d以上,米象成虫耐饥性最弱,7 d后死亡率即达到100%。食物气味对参试成虫的耐饥饿能力具有一定影响,其影响作用大小与储粮害虫种类有关。锈赤扁谷盗成虫的耐饥饿能力受食物气味影响最大,有食物气味存在时其存活时间可以延长7 d。本研究结果对科学实施储粮害虫综合治理具有重要意义。The starvation tolerance of six major stored grain insects including Sitophilus oryzae,Oryzaephilus surinamensis,Tribolium castaneum,Rhizopertha dominica,Cryptolestes ferrugineus and Lasioderma serricorne adults under different starvation conditions were studied.For the tested 6 stored grain insects(1 week old),the results showed that the adults of T.castaneum and L.serricorne adults had strong starvation tolerance,and the duration of starvation tolerance was more than 30 days,followed by adults of O.surinamensis,C.ferrugineus and R.dominica with more than 15 days of the duration of starvation tolerance.The starvation tolerance of S.oryzae adults was the weakest,and all of them died within 7 days.The starvation tolerance of the tested stored grain insects shall be affected by food odor,and the effect degree was related to stored grain insect species.The starvation tolerance of C.ferrugineus adults were most affected by food odor,and the survival time could be prolonged for 7 days when there was food odor.The present results have guiding significance for the scientific application of the integrated pest management of stored grain insects.
