西马丝是玉米的主要害虫。我们的目标是对2000年1月1日至2022年10月1日发表的56篇科学论文进行定性审查和荟萃分析,涉及直接(局部应用)和间接(精油浸渍,EO,在滤纸或玉米粒上)EO对S.zeamamais的接触毒性。使用随机效应模型对LD50(直接接触)和LC50(间接接触)的单个均值进行了三个独立的荟萃分析。更频繁评估的精油是属于菊科的精油,伞形科,唇形科,桃金娘科,胡椒科,还有Rutaceae.局部应用的LC50全球平均值为33.19µg/昆虫(CI9529.81-36.95);滤纸间接接触为0.40µL/cm2(CI950.25-0.65);玉米粒间接接触为0.50µL/g玉米(CI950.27-0.90)。Carumcarvi物种,丹参,地风皮辣椒,persplocasepium,中国三尖杉,Murraya异国情调,杜鹃花,Rutagraveolens,桉树,恶臭眼花,球桉树,桉树,Anethumgraveolens,Iliciumverum,黄蜂,Azadirachtaindica,土荆芥,柏纹,SchinusMolle,PiperHispidinervum,长叶薄荷,巴豆显示LC50或LD50值低于全球平均值,表明良好的杀虫性能。我们的结果表明,EOs具有很大的潜力,可以用作针对S.zeamamais的生物杀虫剂。
Sitophilus zeamais is a primary pest of maize. Our aim was to perform a qualitative review and meta-analyses with 56 scientific articles published from 1 January 2000 to 1 October 2022 dealing with direct (topical application) and indirect (impregnation of essential oils, EOs, onto filter paper or maize grains) contact toxicity of EOs against S. zeamais. Three independent meta-analyses of single means of LD50 (direct contact) and LC50 (indirect contact) were conducted using a random effect model. Essential oils more frequently evaluated were those belonging to Asteraceae, Apiaceae, Lamiaceae, Myrtaceae, Piperaceae, and Rutaceae. The LC50 global mean values were 33.19 µg/insect (CI95 29.81-36.95) for topical application; 0.40 µL/cm2 (CI95 0.25-0.65) for filter paper indirect contact; and 0.50 µL/g maize (CI95 0.27-0.90) for maize grains indirect contact. The species Carum carvi, Salvia umbratica, Ilicium difengpi, Periploca sepium, Cephalotaxus sinensis, Murraya exotica, Rhododendron anthopogonoides, Ruta graveolens, Eucalyptus viminalis, Ocotea odorifera, Eucalyptus globulus, Eucalyptus dunnii, Anethum graveolens, Ilicium verum, Cryptocarya alba, Azadirachta indica, Chenopodium ambrosioides, Cupressus semperivens, Schinus molle, Piper hispidinervum, Mentha longifolia, and Croton pulegiodorus showed LC50 or LD50 values lower than the global means, indicating good insecticidal properties. Our results showed that EOs have great potential to be used as bioinsecticides against S. zeamais.
