摘要
测试了7种植物乙醇提取物对菜小脉蚜茧蜂的影响。结果表明,瑞香、辣椒、加拿大蓬提取物对成 蜂存活、羽化率和寄生作用始终有较大负面影响;鱼腥草和番石榴提取物的作用次之;罗勒和苍耳提取 物对成蜂存活(苍耳在4-48h内)、羽化率和寄生作用无明显影响。
The effects of 7 plant extracts on Diaeretiella Tapae were studied. The results showed that the extracts of Ocimum basilicum and Xanthium sibiricum were safe to the adult survivorship, emergency of adult and parasitism of D. rapae, followed by Houthuynia cordata and Psidium guajava. The extracts of Daphne odora, Conyza canadensis and Capsicum frulesccns, had significantly negative effects on adult survivorship, emergency of adult and parasitism of D. rapae.
