摘要:

为明确蚜虫减量饲喂对双带盘瓢虫幼虫存活和成虫产卵的影响,研究在室内控制条件下开展了相关试验。试验共设置5种饲养密度(5、10、15、20、30头/盒),幼虫阶段采用“低龄期饲喂豆蚜、高龄期饲喂人工饲料”的饲喂策略,成虫阶段则按蚜虫饲喂量设0%、25%、50%、75%和100%五个梯度递减处理。结果显示:(1)A组(自3龄幼虫起转饲喂人工饲料):在30头/盒的饲养密度下,3龄幼虫存活率为65.56%,显著低于其他饲养密度(P<0.05);5头/盒的4龄幼虫存活率为100%;蛹的存活率在82%~94%之间,组间无显著差异(P>0.05);成虫获得率随着饲养密度增加而降低,其中5头/盒的成虫获得率最高(80.00%)。(2)B组(当4龄幼虫起转饲喂人工饲料):4龄幼虫的存活率在74%~87%之间,组间无显著差异(P>0.05);30头/盒的蛹存活率最低(79.53%);5、10、15头/盒的成虫获得率在75%~87%之间,组间无显著差异(P>0.05)。(3)C组(幼虫期全程饲喂蚜虫):成虫获得率最高。(4)成虫产卵表现:双带盘瓢虫的产卵量随着蚜虫饲喂量的减少而下降,其中,蚜虫减量25%时,产卵量为纯蚜虫饲喂的80%;纯人工饲料饲喂的成虫产卵量极少;不同饲喂方式对卵孵化率和成虫存活率均无显著差异(P>0.05)。研究表明,在双带盘瓢虫的幼虫饲养和成虫产卵阶段,以人工饲料部分替代蚜虫具备可行性,但需合理控制蚜虫减量比例并优化饲养密度。

Abstract:

To investigate the effects of reduced aphid feeding on larval survival and adult oviposition of Coelophora biplagiata, controlled laboratory experiments were conducted using a rearing system where early-instar larvae were fed Aphis craccivora and late-instar larvae received artificial diet under five density conditions (5, 10, 15, 20, and 30 larvae/container), combined with graded aphid reduction (0%, 25%, 50%, 75%, and 100%) during adult stage. Results demonstrated: (1) In Group A (artificial diet introduced from 3rd instar larvae), the 3rd instar larvae survival rate under the feeding density of 30 larvae/container was 65.56%, significantly lower than other densities (P<0.05). 4th instar larvae survival rate reached 100% under the feeding density of 5 larvae/container. Pupal survival rates ranged 82%-94% without significant differences (P>0.05). Adult emergence rate decreased with increasing density, peaking at 80.00% under the feeding density of 5 larvae/container. (2) In Group B (artificial diet introduced from 4th instar larvae), 4th instar larvae survival rates remained 74%-87% without significant differences (P>0.05). The lowest pupal survival rate occurred under the feeding density of 30 larvae/container (79.53%). Adult emergence rates under the feeding densities of 5-15 larvae/container ranged 75%-87% with no significant differences (P>0.05). (3) Group C showed highest adult emergence rate. (4) Oviposition performance declined with increasing aphid reduction, achieving 80% of full-aphid diet productivity at 25% aphid reduction. Artificial diet-fed adults showed minimal egg production. No significant differences were observed in egg hatch rates or adult survival across feeding regimes (P>0.05). In conclusion, partial replacement of aphids with an artificial diet is feasible for both larval rearing and adult oviposition of C. biplagiata.
