The invention, which belongs to the field of pest control, particularly relates to a compound medicament for preventing cereal cyst nematode and aphid of wheat. The effective components of the compound medicament comprise imidacloprid and fluopyram in a mass ratio of 3: (0.4-6.7). According to the invention, the proportion of effective components in the compound medicament is improved, and finally, imidacloprid and fluopyram in a certain proportion are selected to be compounded as the effective components. Indoor sterile soil cultivation tests and field tests prove that the compound medicamentis free of phytotoxicity, high in budding rate and good in cyst nematode prevention and control effect; meanwhile, the compound medicament has a good inhibition rate and prevention and control effecton aphids. 本发明属于虫害防治领域，尤其涉及一种兼防小麦孢嚢线虫和蚜虫的复配药剂。所述复配药剂的有效成分包括质量比例为3:0.4-6.7的吡虫啉和氟吡菌酰胺。本发明对于复配药剂中有效成分的比例进行了改进，最终选定一定比例的吡虫啉和氟吡菌酰胺复配作为有效成分。所述复配药剂经室内无菌土栽培试验、大田试验验证，无药害、出芽率高，对孢囊线虫防治效果好，同时对蚜虫也有良好的抑制率和防治效果。
