大谷盗是主要储粮害虫之一,其在具体生态场所发生的共生昆虫种类是其生态学的重要内容之一,也是其综合治理的基础。通过对11个省79个地市的粮库、粮油加工企业、农户等551个单位的调查,发现储粮场所中与大谷盗共同发生的节肢动物涉及蛛形纲和昆虫纲2个纲,计8个目28个科,共60种。昆虫纲中有7个目59种,鞘翅目昆虫占调查到昆虫种类的78%,主要涉及拟步甲科的拟谷盗属、黑粉虫属、小菌虫属、粉盗属等昆虫,以及扁谷盗科、阎虫科、小蕈甲科、露尾甲科、斑螟科、螟蛾科、谷蛾科等类群的昆虫。主要共生昆虫多属于粉食性、菌食性、蛀食性、杂食性等食性,大谷盗共生昆虫的栖息部位主要为粮油加工厂中的车间库房墙角下脚粮堆积处、陈粮长久积存处、提升和输送机底部、地下室、车间杂物(粮)堆放处等。
Big Valley Pi is one of the main stored grain pests, its occurrence in specific ecological sites of symbiotic insect species is one of its important ecological aspects, but also the basis of its comprehensive management. Through the investigation of 551 units such as grain depot, grain and oil processing enterprises and farmers in 79 cities of 11 provinces, it was found that the arthropods involved in the co-occurrence with Dadu Pi in the grain storage sites involved 2 classes of the arachnids and insect classes 8 orders 28 branches, a total of 60 species. Insecta has 7 orders 59 species, Coleoptera insects accounted for 78% of the species surveyed insects, mainly related to the family to be meticulidae mili, genus, small genus, piranha and other insects, As well as the Pterodactyl Division, Yan worm Branch, a small branch of mushroom, the end of the family Acrididae, Ariae, Pyralidae, moth family and other insects. Most of the major symbiont insects belong to powder feeding, feeding habits, eating habits, omnivorous and other feeding habits. The habitats of the big valley symbiotic insects are mainly the grain storage at the corner of the workshop and warehouse in the grain and oil processing plant, the long storage place of Chen Liang, Bottom, basement, shop debris (grain) stacking place.
