Blood-sucking insects are the vectors of many of the most debilitating parasites of humans and their domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides, wool and other products. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically, giving details of the life cycles, bionomics, relationships to disease and economic importance of each of the insect groups in turn.吸血昆虫是人类及其家养动物中许多最有害寄生虫的媒介。此外，由于牛奶和肉类产量的损失以及皮革、羊毛和其他产品的损坏，它们对农业造成了相当大的直接成本。因此，毫不奇怪，许多医学和兽医昆虫学书籍已经出版。这些文本中的大多数都是按分类法组织的，依次给出每个昆虫类群的生命周期、生物学、与疾病的关系和经济重要性的细节。
