| 摘 要： | 棉花是我国重要的经济作物, 虫害严重制约了棉花生产, 造成棉农的经济损失。目前, 化学杀虫剂仍是防治棉花虫害的主要手段, 长期使用化学杀虫剂导致棉蚜Aphis gossypii、绿盲蝽Apolygus lucorum产生抗药性, 降低防治效果。本研究使用80亿孢子/mL金龟子绿僵菌CQMa421可分散油悬浮剂防治棉蚜、绿盲蝽, 室内生测结果表明, 金龟子绿僵菌CQMa421能有效侵染棉蚜和绿盲蝽, 随着浓度的升高, 对棉蚜和绿盲蝽的毒力增强。〖JP+2〗田间试验结果表明, 该药剂能有效控制棉花主要害虫棉蚜和绿盲蝽。采用1 200 mL/hm2用量, 药后14 d对棉蚜的防效达94.42%; 采用1 350 mL/hm2用量, 药后14 d对绿盲蝽的防效分别达到87.25%(新疆), 91.62%(湖北)。

| Abstract: | Cotton is an important cash crop in China. Damage caused by insect pests severely limit cotton production and cause economic losses for cotton farmers. At present, chemical insecticides are still the main means of controlling insect pests in cotton. In this study, Metarhizium anisopliae CQMa421 oil dispersion was used to control cotton aphid (Aphis gossypii Glover) and cotton mirid (Apolygus lucorum). Laboratory results showed that CQMa421 could infect cotton aphid and mirid effectively, and its virulence to cotton aphid and mirid increased with the increase of concentration. In cotton fields, 8 billion spores/mL M. anisopliae CQMa421 oil dispersion can effectively control major cotton pests A. gossypii and A.lucorum. 14 days after the treatment, control efficacy on A. gossypii was 94.42% with the dosage of 1 200 mL/hm2, 87.25% on L.lucorumin Xinjiang and 91.62%in Hubei with the dosage of 1 350 mL/hm2, respectively. |
