中文摘要:【目的】筛选高效储藏物害虫食品级植物源驱避剂。【方法】测定29种植物源化合物在2.5、0.25、0.025、0.0025 μL/cm² 4个剂量下对玉米象Sitophilus zeamais、赤拟谷盗Tribolium castaneum、锈赤扁谷盗Cryptolestes ferrugineus和印度谷螟Plodia interpunctella的驱避效果;同时,以琼脂和海藻酸钠为缓释载体,评价优选驱避混剂的持效性。【结果】化合物对害虫的驱避作用存在显著的虫种特异性和剂量依赖性。在29种化合物中,肉桂醛和香茅醇对赤拟谷盗成虫驱避作用最强;香茅醛、肉桂酸乙酯、对茴香醛和香芹酚对锈赤扁谷盗成虫驱避作用最强;肉桂醛对玉米象成虫和印度谷螟幼虫驱避作用最强。进一步以琼脂和海藻酸钠包埋肉桂醛-香茅醇混剂,缓释15 d后,制剂仍保持良好的驱避活性,且琼脂基制剂的持效性优于海藻酸钠基制剂。【结论】由食品级植物源化合物与琼脂制备的驱避剂持效期长,在食品储藏过程的害虫防治中有较好的应用前景。
英文摘要:[Aim] To develop effective food-grade botanical repellents for stored-product pests. [Methods] The repellency of 29 plant-derived compounds to Sitophilus zeamais, Tribolium castaneum, Cryptolestes ferrugineus, and Plodia interpunctella was determined at dosages of 2.5, 0.25, 0.025, and 0.0025 μL/cm². The effectiveness of using agar and sodium alginate as sustained-release carriers for these repellents was also determined. [Results] Different compounds were repellent to specific pests in a dose-dependent manner. Among the 29 plant-derived compounds tested, cinnamaldehyde and citronellol were the most repellent to adult T. castaneum. Citronellal, ethyl cinnamate, p-anisaldehyde, and carvacrol were the most repellent to adult C. ferrugineus, whereas cinnamaldehyde was the most repellent to adult S. zeamais and larval P. interpunctella. A cinnamaldehyde-citronellol mixture embedded in agar and sodium alginate retained a certain degree of repellency after 15 days; the repellents remained effective longer when combined with the agar formulation than with the sodium alginate formulation. [Conclusion] Repellents prepared from food-grade, plant-derived compounds and agar have considerable potential for reducing the damage to stored food products caused by insect pests.
