摘要

蚂蚁尤其能制造有害的害虫,出没于人类家园,降低作物产量。蚂蚁造成的损害和减轻损害的努力是非常昂贵的。最常用的是广谱杀虫剂;然而,由于它们的副作用,人们对无毒替代品的兴趣越来越大。一种很有前景的商业替代品是2-羟基苯甲醛,它是由各种节肢动物自然产生的化学防御手段,有效地驱蚁。在这里,我们进行了构效关系研究,测试了不同的化学修饰如何改变2-羟基苯甲醛的驱避性。我们发现2-甲氧基苯甲醛比2-羟基苯甲醛在驱除常见的黑园蚁黑蚁方面更有效。接下来,我们比较了对4种特别有害的蚂蚁最有效的驱避化学物质,以确认黑乳杆菌对蚂蚁的结果是普遍的,并且我们的结果与减轻蚂蚁损害的成本有关。

2-Methoxybenzaldehyde effectively repels ants
Ants can particularly make for harmful pests, infesting human homes and reducing crop yields. The damage caused by ants and the efforts to mitigate the damage are hugely costly. Broad-spectrum insecticides are used most commonly; however, due to their negative side effects, there is increasing interest in nontoxic alternatives. One promising commercially available alternative is 2-hydroxybenzaldehyde, which is naturally produced by various arthropods as a means of chemical defense and effectively repels ants. Here we conduct a structure–activity relationship investigation, testing how different chemical modifications alter the repellence of 2-hydroxybenzaldehyde. We find that 2-methoxybenzaldehyde is considerably more effective than 2-hydroxybenzaldehyde at repelling the common black garden ant, Lasius niger. We next compare the most effective repellent chemicals against 4 particularly harmful ant species to confirm that the results obtained with L. niger are general to ants and that our results are relevant to mitigate the costs of ant damage.
