摘  要：
研究了磷化氢低温熏蒸对进口山竹品质的影响及对南洋臀纹粉蚧(Planococcus lilacius Cockerell)和新菠萝灰粉蚧(Dysmicoccus neobrevipes Beardsley)的杀灭效果.在5℃下,分别使用0.28, 0.59, 1.14和2.28 g/m~3磷化氢熏蒸南洋臀纹粉蚧、新菠萝灰粉蚧混合虫态和山竹4 h,统计2种粉蚧死亡率,同时测定山竹可溶性糖、酸度、抗坏血酸(Vc)、总抗氧化能力(T-AOC)和多酚氧化酶(PPO)等品质指标.结果表明,粉蚧雌成虫较若虫耐受力更强,磷化氢0.59 g/m~3即可杀死全部南洋臀纹粉蚧和新菠萝灰粉蚧雌成虫和若虫;熏蒸后贮藏期间山竹可溶性糖变化平稳,酸、 Vc和T-AOC整体略微下降,只有PPO有上升的趋势;但各熏蒸组的果实品质指标与对照组相比差异并无统计学意义,说明磷化氢熏蒸对山竹品质无明显影响.上述研究表明,磷化氢熏蒸可用于进口山竹携带的南洋臀纹粉蚧和新菠萝灰粉蚧的检疫处理, 5℃下使用磷化氢0.59 g/m~3熏蒸4 h可作为备选技术指标.

摘  要：
In this study, the effects of low-temperature phosphine fumigation on the survival of Planococcus lilacius Cockerell and Dysmicoccus neobrevipes Beardsley and on the postharvest quality of imported mangosteen(Garcinia mangostana L.) were investigated. Insects of mixed life stages and mangosteen fruit were treated with phosphine at 0.28, 0.59, 1.14 and 2.28 g/m~3 for 4 h at 5 ℃, then the mortality of the insects and the fruit quality parameters including sugar, acidity, Vc, total antioxidant capacity(T-AOC) and polyphenol oxidase(PPO) were measured. Toxicity test results showed that P. lilacius and D. neobrevipes female adults were more tolerant than their nymphs, and 0.59 g/m~3 phosphine was enough to achieve 100% mortality for all life stages. Fruit quality test showed that there were few changes in soluble solids, slight decrease in titratable acidity, Vc and T-AOC value, and dramatic increase in PPO activity of the stored fruit. In the meanwhile, none of adverse effects on fruit quality were detected in all fumigated groups compared with the control group. In conclusion, the above results indicate that low-temperature phosphine fumigation can be used for the postharvest control of P. lilacinus and D. neobrevipes on mangosteen fruit, and fumigation with 0.59 g/m~3 phosphine for 4 h at 5 ℃ can be used as an alternative treatment schedule.
