摘要
卵育型(Synovigenic)植食性昆虫的雌成虫需要取食寄主植物组织或非寄主食物(如花蜜、花粉等)以延长寿命和促进产卵。为了明确寄主食物和非寄主食物对美洲斑潜蝇Liriomyza sativae卵子发生的功能差异,本实验在明确美洲斑潜蝇成虫卵巢发育动态和结构的基础上,比较了清水(饥饿,对照)、菜豆叶片、20%葡萄糖溶液、菜豆叶片+20%葡萄糖溶液四种处理下的雌成虫卵子发生动态。结果显示:美洲斑潜蝇为强卵育型昆虫,初羽化成虫体内无卵子;两侧卵巢管数之和为11-18根,大多数情况下,左右两侧卵巢管数目不等。成虫在饥饿条件下,几乎不能形成成熟卵子;继续取食寄主叶片、20%葡萄糖溶液和寄主叶片+20%葡萄糖溶液,均可显著促进卵子发生和卵成熟,但补充葡萄糖溶液起到极显著促进作用;成虫不具备卵子重吸收功能。本文重点从卵育型角度,对美洲斑潜蝇取食寄主食物和非寄主食物的营养功能进行了讨论。研究结果为美洲斑潜蝇以及该类植食性害虫的室内饲养和田间生态调控提供了依据。
Host-plant and non-host plant( e. g. nectar and pollen) can prolong longevity and promote oogenesis of emerged female adults in synovigenic herbivores. To understand the difference in the oogenesis function of host plant and non-host plant to Liriomyza sativae,basing on ovary development and anatomy,the oogenesis dynamic of female adults,providing respectively with water( control),leaves +water,20% glucose solution,leaves + 20% glucose solution,were compared in this experiment. The results showed that L. sativae was extremely synovigenic and oocytes were not found in the ovaries of newly emerged female adults. Total ovariole numbers were 11-18 parallel ovarioles. In most cases,left and right ovariole numbers were unequal to female adults. In the condition of starvation,female adults can not almost form mature eggs. Oogenesis and oocytes maturation of female adults continuing to be provided with host leaves,20% glucose solution,host leaves + 20% glucose solution were significantly improved. But providing with glucose solution can extremely significantly accelerate the oogenesis andoocytes maturation. In addition,all of the eggs in female adults were not reabsorbed. From the point of synovigeny,this study concentrated on discussing the nutrient function of feeding on host plant and nonhost plant in L. sativae. The results provide a basis for mass-rearing indoors and in the field of ecological regulation of L. sativae and such herbivores.
