摘要
本文以不同剂量的保幼激素(JH)类似物点滴七星瓢虫雌虫,测定了生殖过程中卵母细胞的长度及血淋巴中卵黄原蛋白(Vg)及总蛋白的含量。结果表朋:1.点滴不同剂量ZR-512于虫体后,皆可促进卵母细胞生长,尤以点滴100μg效果最为明显。2.点滴ZR-512后可以促进Vg合成,血淋巴中Vg含量皆明显提高,以点滴100μg效果最好。3.点滴不同剂量ZR-512后,雌虫血淋巴中总蛋白含量变化与Vg含量变化的规律相似。4.血淋巴中的Vg含量与卵母细胞长度有一定相关性。另外,讨论了不同剂量外源JH类似物对CA活性、内源JH水平、Vg含量以及卵母细胞生长的影响。
The effects of the juvenile hormone analogue (JHA) on the development of oocytes and the synthesis of vitellogenin (Vg) were studied by treating the female seven spotted lady beetle Coccinella septempunctata L. with different doses of ZR 512. The length of the oocytes and the amounts of Vg and total protein in the haeinolymph at different-stages of ovarian development were determined. The results are as follows: After topical application on the abdominal segments with ZR,512 in a suitable range of dosage on the dorsal side, the rate of oocyte growth was nearly positively correlated with the dosage of JHA appled. The most effective dose seemed to be about 100 μg per beetle.The JHA stimulated Vg synthesis in the fat bodies of the insect. After the topical applica-tion with ZR 512 the Vg content in the haemolymph increased markedly and it was most effective when 100 μg of JHA was applied.After the topical application with ZR 512 i different doses the, change of the total protein content in the haemolymph followed the same course of change as shown by vitellogenin.The content of Vg in haemolymph was positively correlated with the length of the oocyte in the early stage of vitellogenesis.
