摘要: 为了明确蚜虫减量饲喂对高密度条件下七星瓢虫(Coccinella septempunctata L.)成虫产卵特性的影响,试验设计0、25%、50%、75%、100%共5个蚜虫减量处理,分别为A(纯蚜虫)、B(3 d蚜虫1 d人工饲料)、C(1 d蚜虫1 d人工饲料)、D(1 d蚜虫3 d人工饲料)、E(纯人工饲料),分析蚜虫减量饲喂对七星瓢虫成虫产卵量、产卵位置选择、孵化率、寿命的影响。结果表明,A、B、C、D、E各处理七星瓢虫产卵量整体随蚜虫饲养量的减少而减少;B处理25%蚜虫减量与A处理纯蚜虫对照无显著差异;七星瓢虫各处理所产卵块绝大多数为可收集卵,卵块的可利用率高;除E处理为纯饲料外,各蚜虫减量处理对七星瓢虫的产卵位置选择、孵化率和寿命无显著影响。综上所述,B处理减量25%的豆蚜,并配合人工饲料饲喂高密度七星瓢虫,各项指标较A处理纯蚜虫对照均无显著差异,可以运用于七星瓢虫的高效繁育。

Abstract: In order to clarify the effects of aphid reduced feeding on the egg laying characteristics of the adult Coccinella septempunctata under high density conditions, five aphid reduced treatments of 0, 25%, 50%, 75% and 100% were designed in the experiment, which were A (pure aphids), B (3-day aphids and 1-day artificial feed), C (1-day aphids and 1-day artificial feed), D (1-day aphids and 3-day artificial feed), and E (pure artificial feed), respectively. The effects of reduced feeding of aphids on egg production, oviposition location selection, hatching rate and life span of the adult ladybird were analyzed. The results showed that the egg-laying capacity of Coccinella septempunctata in A, B, C, D and E treatments decreased with the decrease of feeding capacity of aphids. There was no significant difference between 25% aphid reduction in treatment B and pure aphid in treatment A. Most of the eggs laid by each treatment of Coccinella septempunctata were collected eggs, and the available utilization rate of eggs was high. Except for the pure feed in treatment E, each aphid reduction treatment had no significant effects on the oviposition location selection, hatching rate and life span of the ladybird. To sum up, treatment B, 25% soybean aphid reduction combined with artificial feed, showed no significant difference in all indicators of high density Coccinella septempunctata compared with treatment A, the pure aphid control, which could be applied to the efficient breeding of Coccinella septempunctata.
