We used the Photonic Fence Monitoring Device (PFMD) to evaluate orientation by Musca domestica L. (Diptera: Muscidae), and Calliphora vicina Robineau-Desvoidy (Diptera: Calliphoridae) to the Zevo Flying Insect Trap Model 3. The PFMD's dual cameras record infrared light (IR) reflected from a wavelength-specific fabric; insects do not reflect IR at the same wavelength and are tracked in 3 dimensions as moving objects. The plug-in trap emits ultraviolet and blue light from behind an opaque shield; attracted insects enter the space between the shield and the wall and are trapped on a sticky cartridge facing the wall. An experiment (N = 10) with replicates of approximately 40, 1- to 7-day-old mixed-sex flies of each species was conducted in a 6.1 m3 arena. Prior to turning the trap on, the fly movement was not directed toward the trap on the back wall of the arena, regardless of whether the overhead light was on or off. When the overhead light was off, the mean first catch of both species occurred within 5 min after the trap was turned on, and 33.1% and 41.8% of M. domestica and C. vicina, respectively, were caught. House flies flew toward the trap, many approaching from below, while C. vicina apparently walked or flew outside the field of view of the PFMD until they appeared on the vertical reflective surface, and then walked toward the trap from all directions. Our results show that the Zevo Trap attracts and catches flies, and that the PFMD can be used to track flying and walking flies.
我们使用光子围栏监测设备（PFMD）来评估家蝇（双翅目：蝇科）和红头丽蝇（双翅目：丽蝇科）对Zevo 3型捕蝇器的朝向。PFMD的双摄像头记录从特定波长织物反射的红外光（IR）；昆虫不会反射相同波长的红外光，它们作为移动物体在三维空间中被追踪。插入式捕蝇器在不透明护罩后面发射紫外线和蓝光；被吸引的昆虫进入护罩和墙壁之间的空间，并被困在面向墙壁的粘性盒上。在一个6.1立方米的场地中进行了一项实验（N = 10），每个物种有大约40只1至7日龄的混合性别苍蝇作为重复样本。在打开捕蝇器之前，无论顶灯是否打开，苍蝇的移动都不会指向场地后壁上的捕蝇器。当顶灯关闭时，两种苍蝇的首次捕获平均数都在捕蝇器打开后的5分钟内出现，家蝇和红头丽蝇分别有33.1%和41.8%被捕获。家蝇飞向捕蝇器，许多从下方接近，而红头丽蝇显然在PFMD的视野之外行走或飞行，直到它们出现在垂直反射表面上，然后从各个方向走向捕蝇器。我们的结果表明，Zevo捕蝇器能够吸引并捕获苍蝇，并且PFMD可用于追踪飞行和行走的苍蝇。
