    摘要:

    在江西省内选择5个地市作为代表地区,对粮库、加工厂、饲料厂、农户等调查点的储粮昆虫进行调查。调查发现江西省有60种储粮昆虫,其中鞘翅目昆虫最多,达42种,占70%。拟谷盗Tribolium castaneum Herbst和谷蠹Rhizopertha dominica Fabricius是江西省重要储粮害虫,总发生频率均为69.6%; 12种主要储粮害虫在江西省的总发生频率约大于10%。江西省粮库内的储粮昆虫种类数量为5.4种/调查点。加工厂、饲料厂和农户中储粮昆虫种类数量达11.8种/调查点。江西省地区储粮害虫天敌种类丰富,主要有寄生蜂类、嗜虫蝽类、拟蝎类和捕食螨类,具有生物防治储粮害虫的天然优势。在江西省还首次发现并确定微扁谷盗Cryptolestes pusilloides(Steel et Howe)。

    Abstract:

    The insects in stored grain of grain depots, grain processing factories, feed mills and farmers household in 5cities in Jiangxi province were investigated.60 species of stored grain insects were collected, most of them were coleopteran reached to 42 species,accounting for 70%. Tribolium castaneum Herbst and Rhizopertha dominica Fabricius were most common stored grain insects in this area, both with the total occurrences of 69.6%. Total occurences of 12 species of main pests were generally over 10%. The results also showed there were only 5.4 species per depots on average in grain depots. Compared with grain depots, more insect species were found in grain-processing factories, feed mills and farmers household, about 11.8 species per survey spot on average. It was found that there were many species of natural enemy of stored grain pests in Jiangxi province, the main species were parasitic flies, stinkbugs, pseudoscorpions and predatory mites, which had natural advantages of biological control of stored grain pests. Moreover, Cryptolestes pusilloides (Steel et Howe) was collected in Jiangxi province for the first time.
