| 摘 要： | 本文定量测定在人工饲料中加入埴物油和ZR512对七星瓢虫成虫(第一代)的生殖、摄食、生长、食物利用和转化的影响。结果表明:成虫取食加0.1%橄榄油和ZR512的人工饲料时产卵率能达到96.7%产卵前期为8天左右。如果在此基础上分别添加1%的玉米油或豆油时能促进雌虫产卵量的进一步增加,成虫的增重百分率随着生长天数增加持续上升,取食这种人工饲养的成虫除产卵量外,在体重、产卵前期、产卵率三方面都达到或接近取食蚜虫时的水平。 人工饲料中加入橄揽油能刺激成虫的取食,在此基础上加入玉米油或豆油能使食物转化效率显著地提高。人工饲料中加入ZR512时能阻止或打破雌虫的生殖滞育,促进生殖活动。

| Abstract: | The present work deals with the influence of adding vegetative oils and juvenoid ZR 512 into the artificial diet on the feeding, growth, food utilization and conversion and fecundity of the adult lady beetles Coccinella septempunctata. It was determined on a quantitative basis. The results showed that the precentage of ovipositing females of the first generation reached 96.7% when they were fed on the artificial diet composed of porcine liver homogenate, sucrose and olive oil-juvenoid ZR 512 mixture in the proportion of about 5:2:0.01 after emergence as compared with 82.0% when feeding on aphids. The pre-ovipositional period was about eight days. When soybean oil or corn oil was added into this diet in the proportion of 1.0%, the fecundity of the ovipositing females could be raised and their body weight could also increase during oviposition. When feeding on this diet the female adults showed much similarity to those feeding on aphids in their reproductive activities except the total amount of eggs laid which was about half of the amount when feeding on aphids. The olive oil in the artificial diet seemed to have a phago-stimulating effect on the adult beetles and the rate of food conversion was the highest when soybean oil or corn oil was added into the diet containing 0.1% olive oil and juvenoid mixture. The juvenoid ZR 512 seemed to have the effect of preventing reproductive diapause of the adult beetles. |
