1植物产生吸引天敌的化学信息素，称为食草动物诱导的植物挥发物（HIPV），以应对食草动物的损害。在作物中部署合成HIPV可以加强对害虫的生物控制。为了测试这一点，将六种HIPV [水杨酸甲酯（梅萨）、邻氨基苯甲酸甲酯（MeA）、茉莉酮酸甲酯（MeJA）、苯甲醛（Be）、乙酸顺式-3-己烯酯（HA）、顺式-1-己烯醇（He）]以三种浓度（0.5%、1.0%和2.0%v/v）与植物油佐剂Synertrol®（Organic Crop Protectants Pty Ltd，Australia）混合喷洒到酿酒葡萄、西兰花和甜玉米植物上。2在喷洒后最多22天的不同时间间隔，用非吸引性透明粘性诱捕器评估处理地块内昆虫的相对丰度。3在葡萄园试验中，赤眼蜂对0.5%的Be和1.0%的MeA有反应，小蜂和白蛾对1.0%的MeA有反应，小蜂对1.0%和2.0%的MeA有反应，捕食性昆虫对MeA有反应。在甜玉米中，拟寄生蜂作为一个群体和蜂茧蜂科对MeA（0.5%）有反应;茧蜂科对0.5%的所有化合物和仅Synertrol有反应;蓟马对0.5%和1.0%的所有化合物有反应;而所有拟寄生蜂对0.5%和1.0%的所有化合物和仅Synertrol有反应。在西兰花中，拟寄生蜂作为一个群体和Scelionidae仅对Be，HA，He和Synertrol作出反应;赤眼蜂对Be（0.5%），He（0.5%和1.0%），MeJA（1.0%）和梅萨（0.5%）作出反应;蓟马对0.5%和1.0%的所有化合物作出反应。4在施用HIPV后6天内发生了显著的昆虫引诱，表明植物可能被诱导产生内源性挥发物，这些挥发物在很长一段时间内吸引昆虫。5讨论了合成HIPV在加强害虫生物防治方面的潜在效用。
1 Plants produce natural enemy‐attracting semiochemicals known as herbivore‐induced plant volatiles (HIPV) in response to herbivore damage. Deployment of synthetic HIPV in crops could enhance the biological control of pests. To test this, six HIPV [methyl salicylate (MeSA), methyl anthranilate (MeA), methyl jasmonate (MeJA), benzaldehyde (Be), cis‐3‐hexenyl acetate (HA), cis‐hexen‐1‐ol (He)] in three concentrations (0.5%, 1.0% and 2.0% v/v) mixed with a vegetable oil adjuvant, Synertrol® (Organic Crop Protectants Pty Ltd, Australia), were sprayed onto winegrape, broccoli and sweet corn plants. 2 The relative abundance of insects within treated plots was assessed with non‐attracting, transparent sticky traps at varying time intervals up to 22 days after spraying. 3 In the vineyard experiment, Trichogrammatidae responded to Be and MeA (0.5%) and Be (1.0%); Encyrtidae and Bethylidae responded to MeA (1.0%); Scelionidae responded to all compounds at 1.0% and 2.0%; and predatory insects responded to MeA. In sweet corn, parasitoids as a group and Encyrtidae responded to MeA (0.5%); Braconidae responded to all compounds at 0.5% and Synertrol‐only; thrips responded to all compounds at 0.5% and 1.0%; while all parasitoids responded to all compounds at 0.5% and 1.0% and Synertrol‐only. In broccoli, parasitoids as a group and Scelionidae responded to Be, HA, He and Synertrol‐only; Trichogrammatidae responded to Be (0.5%), He (0.5% and 1.0%), MeJA (1.0%) and MeSA (0.5%); and thrips responded to all compounds at to 0.5% and 1.0%. 4 Significant attraction of insects occurred up to 6 days after the HIPV application, suggesting that plants may have been induced to produce endogenous volatiles that attracted insects over an extended period. 5 The results obtained are discussed in relation to the potential utility of synthetic HIPV to enhance the biological control of pests.
