摘　　要：为查明蓟马为害对澳洲坚果果实质量和大小的影响,对3个品种(HAES344、O.C和HAES246)的果实开展了调查。结果表明:蓟马为害后青皮果单果重减少17.72%~23.78%,平均为21.21%;壳果单果重减少19.15%~26.89%,平均为23.25%;果仁单果重减少9.34%~25.40%,平均为16.86%。蓟马为害后青皮果横径减小6.49%~10.45%,平均为8.93%;壳果横径减小6.55%~10.48%,平均为8.84%。即蓟马为害造成澳洲坚果减产约1/5,果实横径变小约1/10。“蓟马有无”效应、“品种”效应均达极显著水平。Thrips is one of the important pests damaging macadamia nut.An investigation on nut size and weight of three macadamia cultivars(HAES344,own choice and HAES246)was conducted.The results showed that the weight of single green nut is decreased by 17.72%to 23.78%(average 21.21%),the weight of single nut in-shell is decreased by 19.15%to 26.89%(average 23.25%),the weight of single kernel is decreased by 9.34%to 25.40%(average 16.86%).The diameter of single green nut is decreased by 6.49%to 10.45%(average 8.93%),the diameter of single nut in-shell is decreased by 6.55%to 10.48%(average 8.84%).That`s to say,the direct weight loss of macadamia nut production is about one fifth,the diameter of nut is about one tenth smaller.The‘thrips with or without’effect and‘variety’effect reach a very significant level.
