纳米二氧化硅对番茄螟虫产卵抑制效果的研究

哈耶克，r.a.l.， S. Tabbache, A.I.K. Ali和M. Ahmad. 2023。纳米二氧化硅对番茄螟虫产卵抑制效果的研究。植物保护学报，41(3):278-280。https://doi.org/10.22268/AJPP-41.3.278280通过室内实验研究了500和1000 ppm浓度二氧化硅纳米颗粒(SNPs)对绝对图塔(Tuta absoluta)产卵的影响。采用盆栽1个月的番茄植株，随机放置在木笼中(4盆/笼)。每笼放生5对成虫(雄、雌)。在昆虫释放后4天，记录雌虫产卵的数量。结果表明，在不同浓度下，SNPs均能抑制绝对图塔的产卵。单核苷酸多态性处理在1000、750和500 ppm浓度下，卵数分别比对照减少71.17%、59.45%和51.35%。由此可见，纳米二氧化硅作为一种杀虫剂具有潜在的应用前景。关键词:番茄螟虫;抑卵;扫描电镜
