摘  要：
为了明确甲酸乙酯在检疫处理香蕉(Musa paradisiaca)携带杰克贝尔氏粉蚧(Pseudococcus jackbeardsleyi Gimpel et Miller)中应用的可能,本文在13℃下,使用一系列浓度的甲酸乙酯结合15%二氧化碳对杰克贝尔氏粉蚧和海南巴西蕉(Musa paradisiaca)进行了2.5 h熏蒸处理,并测定了甲酸乙酯熏蒸对各虫态杰克贝尔氏粉蚧的毒性及香蕉品质的影响。结果表明香蕉对甲酸乙酯有较强的吸附作用,装载率为40%的条件下,投药后10 min的浓度仅约为投药剂量的30%,熏蒸2.5 h后已不能检测到熏蒸空间中的甲酸乙酯。对各虫态粉蚧的毒力结果表明,粉蚧各虫态对甲酸乙酯的耐受性为卵>雌成虫>若虫,90 g/m3甲酸乙酯熏蒸2.5 h可完全杀灭各虫态粉蚧。品质测定结果表明,甲酸乙酯熏蒸对香蕉的可溶性糖、总酸度和硬度等内部品质无明显影响。本文的结果表明,甲酸乙酯熏蒸能够在储藏温度下有效杀灭各虫态杰克贝尔氏粉蚧,且对香蕉品质无不利影响,因而在水果外食性害虫的检疫处理中具应用前景。

摘  要：
In order to determine whether ethyl formate could be used to control Jack Beardsley mealybug(Pseudococcus jackbeardsleyi Gimpel et Miller) on banana(Musa paradisiaca), in this study under the 13℃, using a series of concentration of ethyl formate combined with 15% carbon dioxide fumigation for 2.5 h, ethyl formate fumigation were measured for each bug state jack bell's mealybug toxicity and quality of fumigated bananas. The banana had the stronger chemisorption to ethyl formate. Under the condition of 40% loading rate, the concentration of the ethyl formate after 10 minutes was only 30%. And after 2.5 hours, the ethyl formate cannot be detected. The tolerance of all insect stages to ethyl formate appeared in the order of egg > the adult > nymph. All stages of mealybug was killed completely when fumigated with ethyl formate at the dosage of 90 g/m3. In the test of the character, fumigation of ethyl formate had no signifi cant effects on internal quality of the banana, including fruit color, fi rmness, soluble sugar content and total acids. These results indicated that ethyl formate was effective to kill the Jack Beardsley mealybug while its adverse effect on the quality of banana could be greatly reduced at low temperature, so control of predatory insect pests using ethyl formate is achievable.
