摘　　要：梨小食心虫(Grapholitha molesta Busck)是世界性危害严重的蛀果害虫之一,性信息素广泛应用于梨小食心虫的测报和诱捕防治。为了确定三角形诱捕器的边长,分别设计了10、20、30、40、50cm 5种不同边长的三角形诱捕器进行诱捕梨小食心虫研究,结果表明,10和20cm直径的三角形诱捕器的诱捕量诱捕达到每天27.6头和22.0头,与30、40、50cm的诱捕器差异显著(F=3.191,df=4,35,P<0.05),10cm边长诱捕量最高。建议在田间诱杀梨小食心虫的三角形诱捕器边长最适范围是10～20cm。明确了三角形诱捕器大量诱捕时的边长,提高了田间梨小食心虫诱捕效率,为果园使用三角形诱捕器防控梨小食心虫提供了一定的参考。The Oriental Fruit Moth （Grapholitha molesta （Busck）） is one of important fruit pests in the world. Sex pheromone traps have been widely used to control this pest. In order to determine the suitable side length of triangular trap for efficient use of the sex pheromone in the field trial, five treatments with different side length of triangular traps were set up, which were 10, 20, 30, 40 and 50era. The results showed that the traps with 10 and 20 cm side length possessed the highest efficiency on catching the moths in which the daily average trapping number were 27.6 and 22.0, respectively, and were significantly different from other traps （F--3. 191, df= 4,35, P〈0.05）. The most effective trap was the one with 10cm side length. Based on the results, the optimum side length range of triangle trap in the field was proposed as 10-20 cm which could be used for ef fectively monitoring the Oriental fruit moth in the orchard and could provide useful information for the application of triangular traps to monitor the Oriental fruit moth in the orchard.
