彩色盘诱捕是一种简单而有效的收集飞行昆虫的方法，但对于特定目标群体（例如传粉昆虫）最有效的诱捕盘颜色仍有争议。特定颜色的成功可能因生物区域和栖息地的不同而有所不同。大多数已发表的盘式诱捕器研究都是在北半球进行的，很少研究栖息地对盘式诱捕器捕获量的影响。我们的研究是第一个：（1）澳大利亚桉树植被和杏仁园中潜在授粉媒介的样本；（2）调查栖息地是否与诱集器颜色相互作用以影响盘式诱集器的捕获量。我们在澳大利亚维多利亚州西北部墨累马利生物区的本地马利植被和两种类型的管理杏仁园（单一栽培和植物多样性）中使用黄色、白色和蓝色盘式诱捕器对膜翅目和双翅目昆虫进行了采样。黄色诱捕器在所有栖息地捕获的昆虫最多，尽管每个颜色诱捕器的捕获量因栖息地而异。对于所有昆虫类群而言，蓝色诱捕器在桉树栖息地捕获的个体数量多于在杏仁园捕获的数量。对于本地膜翅目动物，黄色陷阱在植物多样化的果园中捕获的个体比在本地地点捕获的个体更多，而蓝色陷阱在本地地点捕获的个体更多。我们的结果强调了考虑单个盘诱捕调查的栖息地的重要性，因为没有一种诱捕颜色可能适合在所有栖息地诱捕目标昆虫。
Coloured pan trapping is a simple and efficient method for collecting flying insects, yet there is still discussion over the most effective bowl colour to use for particular target groups (e.g. pollinator insects). The success of particular colours can vary across bioregions and habitats. Most published pan trap studies have been conducted in the northern hemisphere, and very few investigated the effects of habitat on pan trap catches. Our study is one of the first to (1) sample for potential pollinators in Australian mallee vegetation and almond orchards and (2) investigate whether habitat interacts with trap colour to influence pan trap catches. We sampled Hymenoptera and Diptera using yellow, white and blue pan traps in native mallee vegetation and two types of managed almond orchards (monoculture and plant-diverse) in the Murray Mallee bioregion of north-western Victoria, Australia. Yellow traps caught the most insects across all habitats, although catches in each colour trap varied with habitat. For all insect groups combined, blue traps caught more individuals in mallee habitats than in almond orchards. For native hymenopterans, yellow traps caught more individuals in plant-diverse orchards than in native sites, while blue traps caught more individuals in native sites. Our results highlight the importance of considering the habitat of individual pan trapping surveys, as no one trap colour is likely to be suitable for trapping target insects across all habitats.
