| 中文摘要: |
| 为探究土壤添加生物质炭对植食性咀嚼式口器害虫的影响，选用黏虫为研究对象，设0、15、30和50 g·kg-1四个土壤添加生物质炭处理，对盆栽种植的麦苗接初孵黏虫幼虫，观察和分析幼虫生长发育和成虫生殖力的变化。结果表明，随生物质炭施用量的增大，黏虫幼虫发育历期呈线性缩短趋势，50 g·kg-1生物质炭处理下幼虫发育历期为19.0 d，较不添加生物质炭处理下降6.5%。黏虫蛹鲜重随生物质炭添加量增大呈线性减小趋势，其中50 g·kg-1生物质炭处理下雌虫蛹鲜重为0.28 g，较不添加生物质炭处理下降12.5%。施加生物质炭对黏虫的化蛹率（平均69.89%）和羽化率（92.08%）无显著影响。但随生物质炭施用量的增大，黏虫产卵量呈线性增大的趋势，50 g·kg-1生物质炭处理产卵量为605粒，较不添加生物质炭处理下增加近3.3倍。以上结果说明，施用生物质炭有提高黏虫生殖潜力的作用。 |
| 英文摘要: |
| To explore the potential of biochar amendment to soils in influencing chewing insect pests, laboratory experiments were conducted using the oriental armyworm Mythimna separata(Lepidoptera: Noctuidae) as a model species. Biochar was added at the levels of 0, 15, 30 and 50 g·kg-1 to soils in the pots planted with wheat. Neonate larvae were individually transferred onto potted wheat seedlings and observed throughout their development. Larval duration showed a linear downward trend across the increasing levels of biochar application, with a decrease rate of 6.5% to 19.0 d at the highest biochar-added level. Additionally, pupal weight showed a linear downward trend across the increasing levels of biochar application, from 0.32 g in the control by a decrease rate of 12.5% to 0.28 g at the highest biochar-added level. Larval pupation rate(92.08%) and adult eclosion rate(69.89%) did not change across the biochar amendment levels. However, lifetime fecundity demonstrated a linear upward trend across the increasing levels of biochar application, from 142 eggs laid per female in the control to 605 eggs at the highest biochar-added level. It is suggested that biochar amendment to soils may improve the reproduction of M.separata. |
