摘　　要：储粮害虫防治的基础是害虫的鉴定和识别。对于储粮昆虫的鉴定识别,目前主要依据是检索表。常用的检索表是两项式检索表。本文通过对两项式检索表进行抽象分析,以储粮象虫检索表为例,建立了对应的二叉树的数据结构,分享了数字化应用构建过程。通过建构的数据结构进行数据库设计,讨论了储粮昆虫数据库存储的昆虫编码,给出了数据库结构。同时,还在上述方法的基础上,进行了软件系统的开发和实现,以鞘翅目象虫科检索表为例子进行了使用验证,通过二叉树的遍历快速完成检索表的检索,精确地进行检索表的任意关键词查询,更符合储粮象虫检索表的使用习惯,并在全国储粮昆虫调查后期数据处理中得到了应用,效果良好。Identification and identification of stored grain pests are the basis of pest control.For the identification the main basis is the identification keys.A commonly used search keys is a dichotomous classification identification keys.In this paper,through the abstract analysis of the dichotomous classification and retrieval keys,the correspond ing two-dimensional keys was established by taking the storage grain worm identification keys as an example.The construction process of the binary tree was analyzed,and the binary tree data structure suitable for computer process ing was obtained.The database design was carried out by constructing the binary tree data structure.The insect cod ing stored in the grain storage insect database was discussed and the database structure was given.At the same time,on the basis of the above methods,the development and implementation of the software system were carried out.The key table of Coleoptera family was used as an example for verification.Through the traversal of binary tree,the search of the key table can be completed quickly,and any key words of the key table could be queried accurately,which was more in line with the use habit of the key table of stored grain weevil.It has been applied in the data processing of the later stage of the national grain storage insect survey,and the effect is good.
