摘要
本文研究了番石榴果肉挥发物化学组成及对桔小实蝇产卵行为的影响。通过气相色谱与质谱联用对番石榴果肉挥发物进行了分析,并比较了番石榴果肉挥发物和不同引诱物对桔小实蝇成虫诱集虫口数和产卵量的差异。化学组成分析结果表明,检出的番石榴果肉挥发物共18种化合物,含量最高的为乙酸叶醇酯,占40.07%,其次为石竹烯,占23.55%。桔小实蝇成虫产卵行为生测结果表明,番石榴果肉对桔小实蝇的引诱效果显著高于蔗糖、清水对照和空白对照,但低于水解蛋白。番石榴果肉和水解蛋白具有诱集桔小实蝇产卵的作用,桔小实蝇在番石榴果肉和水解蛋白两个处理上24h产卵量分别为6.80±0.23和7.07±0.16粒/管,显著高于桔小实蝇在其它处理上的产卵量。桔小实蝇的产卵量随番石榴果肉重量增加而增加,当番石榴果肉增加至11g时,桔小实蝇的产卵量达最大值46.32±0.35粒/管。
The chemical constituents of guava fruit flesh volatiles and their effect on oviposition behavior of oriental fruit fly （ Bactrocera dorsalis Hendel） was studied. Guava fruit flesh volatiles were analyzed by GC - MS, and the differences of amount of responded oriental fruit fly adults and eggs laid by oriental fruit fly effected by guava fruit flesh volatiles and other lures. Result of chemical constituents analysis indicated that 18 kinds of components were detected. The highest content component was （Z） -3 - Hexen - 1 - ol acetate, followed by caryophyllene, and their relative contents were 40. 07% and 23.55% respectively. The results of oviposition behavior of oriental fruit fly tests showed that attractant effect of guava fruit flesh was significantly higher than that of sucrose, water control and blank control. But its attractant effect was lower than protein hydrolysate＇s. Guava fruit flesh and protein hydrolysate had the effect of attracting oriental fruit fly to lay eggs. The eggs laid by oriental fruit fly with guava fruit flesh and protein hydrolysate after 24 h were 6. 80± 0.23 and 7.07 ± 0. 16 egg/tube respectively, which were significantly higher than other treatments. The eggs laid by oriental fruit fly were increased with the increase of weight of guava fruit flesh which can produce volatiles. Maximum eggs were collected, when the weight of guava fruit flesh increased to 11 g. The amount of eggs laid by oriental fruit fly would tend to be unchanged while adding more guava fruit flesh.
