摘要在实验室中，阿根廷蚂蚁Linepithema humile（Mayr）的死亡率与芳香雪松覆盖物的长度呈正相关，在食物到达之前必须穿过该覆盖物。当蚂蚁可以在不穿过覆盖物的情况下获取食物时，死亡率与覆盖物部分长度无关。在该领域，阿根廷蚂蚁表现出一种倾向，以避免芳香雪松覆盖物作为筑巢基板。在建筑物旁边的植物床中，发现的蚁巢（包含育雏的口袋）的数量在芳香雪松和柏树覆盖物之间没有显着差异。然而，当橡树周围的松树秸秆覆盖物取代芳香雪松或柏树覆盖物，蚂蚁巢的数量相似，发现在柏树覆盖物中的原始松树秸秆，而芳香雪松覆盖物的数量显着较低。此外，与柏树覆盖物或原来的松树秸秆相比，在芳香雪松覆盖物包围的树上跟踪的蚂蚁更少。被放置在建筑物旁边的苹果果冻诱饵吸引的蚂蚁数量在覆盖物类型之间没有差异;穿过建筑物周围覆盖物床的蚂蚁踪迹的数量也没有差异。我们建议，芳香雪松覆盖物可能有助于控制阿根廷蚂蚁和减少杀虫剂的投入时，与传统的控制方法相结合。
Abstract In the laboratory, Argentine ant, Linepithema humile (Mayr), mortality was positively correlated to the length of an aromatic cedar mulch section that had to be crossed before food could be reached. When ants could access food without crossing the mulch, mortality was not correlated to mulch section length. In the field, Argentine ants showed a tendency to avoid aromatic cedar mulch as a nesting substrate. In plant beds alongside buildings the number of ant nests (pockets containing brood) found was not significantly different between aromatic cedar and cypress mulch. However, when pine straw mulch around oak trees was replaced with aromatic cedar or cypress mulch, a similar number of ant nests was found in the cypress mulch as in the original pine straw, whereas numbers in aromatic cedar mulch were significantly lower. Also, fewer ants were trailing on the trees surrounded by aromatic cedar mulch compared with cypress mulch or the original pine straw. The number of ants attracted to apple jelly baits placed alongside the buildings did not differ between mulch types; neither did the number of ant trails crossing the mulch beds around the buildings. We suggest that aromatic cedar mulch may help control Argentine ants and reduce insecticide input when applied in combination with conventional control methods.
