| 摘 要： | 为了弄清番石榴果实的最佳套袋时间,室内试验研究番石榴果实硬度对橘小实蝇Bactrocera dorsalis(Hendel)产卵选择性的影响。结果表明,果实的硬度越小,对橘小实蝇雌虫的引诱作用越强,并且不同硬度范围的果实引诱的产卵量存在显著性差异。当番石榴果实硬度>11kg.cm-2时,橘小实蝇不会在其上面产卵,此时是最佳的果实套袋时期。

| Abstract: | Ovipositional preferrence of Bactrocera dorsalis （Hendel） to Psidium guajava L. fruits with different hardness was studied in order to confirm the best bagging time of fruit. The results showed that with the fruit hardness decreasing, the ovipositional preferrence became stronger. The egg quantity on the fruits with different hardness was significantly different. When the fruit hardness was higher than 11kg·cm^-2, the egg quantity on the fruit was zero,so it is the best bagging time of fruit. |
