| 黄曲条跳甲 Phyllotreta striolata 是为害十字花科蔬菜的重大害虫?本文研究了种子丸粒化包衣?拌土撒施和叶面喷雾3种施药方式下苏云金杆菌 Bacillus thuringiensis G033A和金龟子绿僵菌 Metarhizium anisopliae CQMa421对为害菜心 Brassica campestris L. ssp. chinensis var. utilis 的黄曲条跳甲的防治效果?结果表明, 采用苏云金杆菌G033A和金龟子绿僵菌CQMa421进行种子丸粒化包衣处理的菜心, 叶片受害指数分别为6.71和9.93, 显著低于对照(31.79); 拌土撒施处理的菜心, 叶片受害指数分别为19.34和24.17, 显著低于对照(65.53); 〖JP+1〗叶面喷雾处理后第3?5?7天的校正防治效果分别为58.95%/52.37%?69.56%/64.04%和81.12%/70.09%?本研究探索了菜心生产中主要害虫的生物防治技术, 研究结果将为菜心生产过程黄曲条跳甲的有效防治提供技术支撑? |
| 英文摘要: |
| Striped flea beetle, Phyllotreta striolata is an important pest of cruciferous vegetables. Here we investigated the application techniques of two biopesticides, Bacillus thuringiensis G033A (Bt G033A) and Metarhizium anisopliae CQMa421, for the control of P.striolata in the whole process of Chinese flowering cabbage production. The results showed that both biopesticides have good control effects with three application methods, seed coating treatment, soil treatment and foliar application. Using seed coating treatment and soil treatment, Bt G033A and M.anisopliae CQMa421 could obviously prevent the damage of P.striolata in the seedling stage of Chinese flowering cabbage. The leaf damage index (LDI) of Bt G033A and M.anisopliae CQMa421 by seed coating treatment was 6.71 and 9.93, respectively, significantly lower than that of the control (31.79). The LDI of Bt G033A and M.anisopliae CQMa421 by soil treatment was 19.34 and 24.17, respectively, significantly lower than the control (65.53). The corrected control efficacies on the 3rd, 5th and 7th day after foliar spray treatment were 58.95%/52.37%, 69.56%/64.04% and 81.12%/70.09%, respectively. This research explores the biological control technology of P.striolata, which will provide technical support for biological control of pests in the production of Chinese flowering cabbage. |
