Grapholitha molesta (Busck) and Carposina nipponensis Walsingham are two of the important fruit\|boring pests on fruit trees in Yanluo, northeast Beijing. Their occurrence and bionomics were investigated and reported. Integrated control with sex attractant, which reduced the fruit\|boring rate from 60% to 2%, is recommended as an effective measure to control the two fruit\|boring pests on fruit trees.
