摘要
研究了肉桂精油(EO)和(E)-肉桂醛对植物寄生虫 Meloidogyne incognita、Globodera rostochiensis 和 Xiphinema index 的活性。将 M. incognita 和 G. rostochiensis 的幼虫(J2)或卵以及 X. index 的混合年龄标本暴露于 12.5-100 µg mL-1 浓度的这两种产品中。在盆栽番茄和马铃薯上分别评估了土壤处理中 100-800 mg kg-1 决明子环氧乙烷和(E)-肉桂醛对 M. incognita 和 G. rostochiensis 的抑制作用。暴露于 12.5 µg mL-1 的(E)-肉桂醛溶液 24 小时后,M. incognita J2 的死亡率超过 68%,而相同浓度的全环氧乙烷的死亡率较低。G. rostochiensis J2 与这两种产品的 12.5 µg mL-1 溶液接触 4 小时后,死亡率分别为 39% 和 42%。所有 X. index 标本分别在接触 100 µg mL-1 的环氧乙烷和(E)-肉桂醛溶液 48 小时和 8 小时后死亡。将 M. incognita 卵块或 G. rostochiensis 囊蚴分别暴露于 800 µg mL-1 浓度的环氧乙烷和(E)-肉桂醛溶液中 24 小时和 96 小时后,卵孵化率降低了 90% 以上。番茄和马铃薯上的 M. incognita 和 G. rostochiensis 的侵染在使用这两种产品的所有土壤处理中均显著减少,但(E)-肉桂醛对这两种线虫的抑制作用通常比全部环氧乙烷更强。根据这些结果,决明子环氧乙烷和(E)-肉桂醛可作为新型环境友好型杀线虫剂的潜在来源。
Nematicidal activity of the essential oil from Cinnamomum cassia and (E)-cinnamaldehyde against phytoparasitic nematodes
The activity of Cinnamomum cassia essential oil (EO) and (E)-cinnamaldehyde was investigated on the phytoparasitic species Meloidogyne incognita, Globodera rostochiensis, and Xiphinema index. Juveniles (J2) or eggs of M. incognita and G. rostochiensis and mixed-age specimens of X. index were exposed to 12.5–100 µg mL−1 concentrations of the two products. The suppressiveness of soil treatments with 100–800 mg kg−1 soil rates of the C. cassia EO and (E)-cinnamaldehyde to M. incognita and G. rostochiensis was assessed on potted tomato and potato, respectively. A 24-h exposure to a 12.5 µg mL−1 solution of (E)-cinnamaldehyde resulted in more than 68% mortality of M. incognita J2, while a poor mortality occurred at the same concentration of the whole EO. The mortality of G. rostochiensis J2 ranged 39 and 42%, respectively, since after a 4-h exposure to a 12.5 µg mL−1 solution of both products. All the X. index specimens died after a 48- and 8-h exposure to a 100 µg mL−1 solution of the EO and (E)-cinnamaldehyde, respectively. Egg hatch was reduced by more than 90% after exposing the M incognita egg masses or the G. rostochiensis cysts to 800 µg mL−1 concentration of both EO and (E)-cinnamaldehyde for 24 and 96 h, respectively. The infestation of M. incognita and G. rostochiensis on tomato and potato, respectively, was significantly reduced by all soil treatments with both products, though (E)-cinnamaldehyde generally resulted more suppressive than the whole EO to both nematode species. According to these results, C. cassia EO and (E)-cinnamaldehyde could be suggested as a potential source of new environment-friendly nematicides.
期刊介绍:
Journal of Pest Science publishes high-quality papers on all aspects of pest science in agriculture, horticulture (including viticulture), forestry, urban pests, and stored products research, including health and safety issues.
Journal of Pest Science reports on advances in control of pests and animal vectors of diseases, the biology, ethology and ecology of pests and their antagonists, and the use of other beneficial organisms in pest control. The journal covers all noxious or damaging groups of animals, including arthropods, nematodes, molluscs, and vertebrates.
Journal of Pest Science devotes special attention to emerging and innovative pest control strategies, including the side effects of such approaches on non-target organisms, for example natural enemies and pollinators, and the implementation of these strategies in integrated pest management.
Journal of Pest Science also publishes papers on the management of agro- and forest ecosystems where this is relevant to pest control. Papers on important methodological developments relevant for pest control will be considered as well.
