Abstract
An insect trap has a hollow body generally centered on an upright axis, having a central upwardly open output passage, and formed around the central output passage with an annular intake passage having a dark-colored inner surface. A light-colored foraminous wall upwardly covers the central output passage and has a surface area substantially greater than that of the intake passage. A blower in the body expels air from the body through the central output passage and through the foraminous wall at a predetermined low speed and draws air into the annular intake passage at a high speed substantially higher than the predetermined low speed. Insects attracted by the weak stream or by a contrast between the dark-colored inner surface and the light-colored foraminous wall are trapped in the annular intake passage.
