Abstract:
Understanding the nutritional interplay among plants, pests, and natural enemies is essential for sustainable pest management. Enhancing the efficiency of natural enemies, such as Neoseiulus californicus (McGregor) (Acari: Phytoseiidae) is critical, and exploiting herbivore-induced plant volatiles (HIPVs) offers a promising approach. However, N. californicus has rarely been reported to utilize HIPVs to improve their biological control capabilities. Our research revealed a significant difference in the diversity of volatile compounds detected in clean Citrus reticulata Blanco leaves compared to those in C. reticulata leaves infested with Panonychus citri (McGregor) (Acari: Tetranychidae), regardless of mite presence. This suggests that P. citri infestation induces a wide array of HIPVs in C. reticulata leaves. We conducted olfactory behavioral assays to evaluate the response of N. californicus to synthetic HIPVs. Results revealed that linalool (1.00 mg/mL), 2,2,4-trimethylpentane (10.0 mg/mL), undecylcyclohexane (1.00 mg/mL), and (+)-dibenzoyl-L-tartaric anhydride (10.0 mg/mL) significantly attracted N. californicus while pentadecanal (1.00 mg/mL) significantly deterred it. A 3-component blend of linalool, undecylcyclohexane, and (+)-dibenzoyl-L-tartaric anhydride was better than other combinations in attracting N. californicus. This combination provided the basis for developing an attractant for N. californicus, facilitating the rate of its dispersal to enhance its biological control of pests. Consequently, this research offers vital insights into improving the sustainable pest control potential of predatory mites.
摘要:
了解植物之间的营养相互作用,害虫,天敌对于可持续的害虫管理至关重要。提高天敌的效率,如新考利(McGregor)(Acari:Phytoseiidae)至关重要,利用草食动物诱导的植物挥发物(HIPV)提供了一种有前途的方法。然而,加利福尼亚N.很少有报道利用HIPV来提高其生物防治能力。我们的研究表明,在干净的网状柑橘叶片中检测到的挥发性化合物的多样性与感染了Panorychuscitri(McGregor)(Acari:Tetranychidae)的网状柑橘叶片中的挥发性化合物的多样性存在显着差异,不管螨虫的存在。这表明柑桔疫霉侵染在网状梭状芽孢杆菌叶中诱导了大量的HIPV。我们进行了嗅觉行为测定以评估加利福尼亚N.对合成HIPV的反应。结果显示芳樟醇(1.00mg/mL),2,2,4-三甲基戊烷(10.0mg/mL),十一烷基环己烷(1.00mg/mL),和()-二苯甲酰基-L-酒石酸酐(10.0mg/mL)显着吸引了加利福尼亚N.,而十五醛(1.00mg/mL)显着阻止了它。芳樟醇的3组分混合物,十一烷基环己烷,(+)-二苯甲酰基-L-酒石酸酐在吸引加利福尼亚N.这种结合为开发加州奈瑟氏菌引诱剂提供了基础,促进其传播速度,以加强其对害虫的生物防治。因此,这项研究为提高捕食性螨的可持续害虫控制潜力提供了重要的见解。
