摘要
竹笋禾夜蛾是竹林经营中的常见害虫,对竹笋和竹材危害较大,影响其产量和质量。为更好地防治竹笋禾夜蛾,提高毛竹产量和品质,促进竹业健康持续发展,分析化学防治、物理防治和营林措施等综合防治措施,对不同立竹密度毛竹发笋成竹和毛竹林退笋情况的影响。结果表明,保持低于150株/667 m^(2)的立竹密度,可以提高竹笋成竹率、降低害虫退笋率;实施综合防治措施后,毛竹林发笋成林率更高,害虫退笋率减少。采取综合防治技术,可以有效地减少毛竹竹笋禾夜蛾的危害,降低害虫退笋率,提高毛竹害新笋成竹率。
Oligia vulgaris are common pests in Phyllostachys edulis forest management,causing significant harm to Phyllostachys edulis shoots and timber,affecting the yield and quality of Phyllostachys edulis shoots and timber.In order to better control the Oligia vulgaris,improve the yield and quality of Phylostachys edulis,and promote the healthy and sustainable development of the Phyllostachys edulis industry,the effects of comprehensive control measures were analyzed such as chemical control,physical control,and afforestation on the occurrence and decline of bamboo shoots at different stand densities.The results showed that maintaining a standing bamboo density below 150 plants/667 m^(2) could increase the Phyllostachys edulis shoot formation rate,and reduced the pest retreat rate.After implementing comprehensive prevention and control measures,the incidence of Phyllostachys edulis shoots in Phyllostachys edulis forests after prevention and control was higher,while the reduction rate of insect infestation was lower.By adopting comprehensive prevention and control techniques,the harm of Oligia vulgaris could be effectively reduced,the rate of pest retreat could be reduced,and the rate of new Phyllostachys edulis shoots forming in Phyllostachys edulis could be increased.
