Abstract

Click beetle larvae have been observed to cause crop damage in various regions worldwide; however, accurate prediction of plant damage is hindered by their subterranean life cycle and the associated challenges in sampling. Melanotus senilis, a beetle belonging to the subfamily Elaterinae (tribe Melanotini) within the family Elateridae, is a destructive agricultural pest that harms maize, hops, and ginger. Our study presents novel evidence indicating the attraction of M. senilis larvae to Citrus natsudaidai (Japanese name “Natsumikan” or “Natsudaidai”). Through a field experiment involving different citrus fruits, namely natsumikan, oranges, and grapefruits, we found that C. natsudaidai attracted the highest number of M. senilis larvae. Furthermore, in a separate experiment in which C. natsudaidai and potatoes were placed in the field, C. natsudaidai significantly outperformed potatoes in attracting M. senilis larvae. These findings suggest that C. natsudaidai fruit placed on the soil surface attracts M. senilis larvae. C. natsudaidai fruits used in this study were sourced from those that remained unharvested until August. Therefore, it is possible that the C. natsudaidai fruits used for comparison were more mature than the citrus fruits used in this study. It is possible that the ripening of C. natsudaidai may have led to changes in CO2 and ethylene emissions, potentially attracting a greater number of M. senilis larvae. Further research is required to explore these aspects in detail.

利用柑橘的潜力:吸引黑线蝇幼虫的诱饵
据观察,槌状甲虫幼虫在世界各地都会对作物造成危害;然而,由于其地下生活周期以及取样方面的相关挑战,对植物危害的准确预测受到了阻碍。Melanotus senilis是一种甲虫,隶属于Elateridae科Elaterinae亚科(Melanotini族),是一种破坏性农业害虫,主要危害玉米、啤酒花和生姜。我们的研究提供了新的证据,表明柑橘夏大青虫对柑橘(日语名称 "Natsumikan "或 "Natsudaidai")的吸引力。通过一项涉及不同柑橘类水果(即夏橙、橘子和葡萄柚)的田间试验,我们发现夏橙吸引了最多的仙客来幼虫。此外,在另一个实验中,将夏枯草和马铃薯放在田间,夏枯草在吸引森尼拉斯幼虫方面明显优于马铃薯。这些研究结果表明,放置在土壤表面的夏枯草果实能吸引仙客来幼虫。本研究中使用的夏枯草果实来自八月前仍未采收的果实。因此,用于比较的夏威夷果可能比本研究中使用的柑橘类水果更成熟。夏枯草的成熟可能导致二氧化碳和乙烯排放的变化,从而可能吸引更多的仙客来幼虫。要详细探讨这些方面的问题,还需要进一步的研究。
