摘　　要：本研究调查了草地贪夜蛾卵块在田间玉米植株上的空间分布,发现草地贪夜蛾卵块主要分布于植株中部,即玉米小喇叭口期倒3叶与倒4叶、吐丝期倒5叶与倒6叶上卵块最多,在小喇叭口期主要分布在叶正面,吐丝期主要分布于叶背面,距叶尖平均距离分别为23.4 cm和35.2 cm。为玉米上草地贪夜蛾卵的调查和防治提供了参考。The spatial distribution of fall armyworm Spodoptera frugiperda egg masses was investigated in corn field.The results indicated that the egg masses were mainly located in the middle of corn plant,where in the 3rd-4th leaves from the top of the plants at early whorl stage,and the 5th-6th leaves from the top of the corn plants at silking stage.The egg masses of S.frugiperda were mainly distributed on the adaxial surface of corn leaf at the early whorl stage,and on the abaxial surface of corn leaf at the silking stage,with the average distance of 23.4 cm and 35.2 cm to the leaf tip,respectively.The results will provide useful information for the investigation and control of S.frugiperda egg in corn field.
