摘要:

豆大蓟马是豆科作物的重要害虫,给我国豆科作物种植产业造成巨大损失。基于昆虫信息素和植物挥发物的行为调控技术是豆大蓟马重要的绿色防控措施。本研究旨在筛选对豆大蓟马具有引诱作用的植物挥发物,以明确聚集信息素与植物挥发物互作对豆大蓟马的行为调控作用,并筛选聚集信息素和植物挥发物增效配方。结果表明,特定剂量的芳樟醇(0.1 μL·mL-1)、异烟酸甲酯(1.0 μL·mL-1)和丁香酚(1.0 μL·mL-1)能够显著引诱豆大蓟马雌成虫。将上述剂量的3种挥发物分别与豆大蓟马聚集信息素(最佳引诱剂量5.00 ng·μL-1的反式,反式-金合欢醇乙酸酯)混合后,芳樟醇和丁香酚对反式,反式-金合欢醇乙酸酯具有拮抗作用,而异烟酸甲酯则对反式,反式-金合欢醇乙酸酯没有拮抗作用,说明5.00 ng·μL-1反式,反式-金合欢醇乙酸酯与1.0 μL·mL-1异烟酸甲酯的组合可作为豆大蓟马引诱剂的优化配比。本研究筛选出了3种能够显著引诱豆大蓟马的植物挥发物,明确了植物挥发物与聚集信息素的相互作用,为基于信息化合物的豆大蓟马行为调控技术奠定了基础,同时为开发高效豆大蓟马引诱剂提供了依据。

Abstract:

Megalurothrips usitatus is an important pest on leguminous crops, and has been reported to cause tremendous losses to leguminous crops industry in China. Aggregation pheromone and plant volatiles based behavioral manipulation techniques are promising eco-friendly control tactics for M. usitatus. The aim of this study was to screen plant volatiles with attractive activities to M. usitatus, investigate the interaction between aggregation pheromone and plant volatiles, and develop synergist blends. The results showed that 0.1 μL·mL-1 linalool, 1.0 μL·mL-1 methyl isonicotinate and 1.0 μL·mL-1 eugenol were attractive to M. usitatus female adults. When the three volatile compounds at the specified doses were mixed with the aggregation pheromone components of M. usitatus at the optimal luring dose [5.00 ng·μL-1 (E, E)-farnesyl acetate] respectively, eugenol and linalool showed antagonistic effects against (E,E)-farnesylacetate. By contrast, methyl isonicotinate showed no antagonistic effect on (E,E)-farnesylacetate, indicating that the combination of 5.00 ng·μL-1 (E, E)-farnesyl acetate and 1.0 μL·mL-1 methyl isonicotinate can be used as an optimized ratio for the bait of M. usitatus. This study screened out three plant volatiles which can significantly attract M. usitatus, clarified the interaction between plant volatiles and aggregation pheromone, which provided the basis for the behavior regulation technology of M. usitatus based on information technology and provided references for the development of efficient M. usitatus attractants.

Key words: Megalurothrips usitatus, aggregation pheromone, plant volatile, behavioral regulation
