The invention belongs to the technical field of
safe storage of food grains, and concretely discloses a Plodia interpunctella trap. The Plodia interpunctella trap comprises a cylinder, the cylinder ismade of a transparent brown plastic material, and a bait box is arranged at the center of the upper end surface of the cylinder; a suction fan is arranged in the cylinder, the bottom of the cylinderbody is sealed with a conical seal bottom, the conical seal bottom is made of a
polytetrafluoroethylene material, a Plodia interpunctella passing port is arranged at the
small head end of the conicalseal bottom, the
diameter of the Plodia interpunctella passing port is 10 mm, and an included angle between the
conical surface of the conical seal bottom and the horizontal plane is 30 DEG; the innerwall, close to the upper end surface, of the cylinder is uniformly provided with Plodia interpunctella attracting lamp beads along the
peripheral wall of the cylinder, every Plodia interpunctella attracting lamp bead adopts an
ultraviolet lamp with a
wavelength of 365 nm, and a downwardly inclined reflective sheet is arranged under every Plodia interpunctella attracting lamp bead; and a Plodia interpunctella
trapping net bag sleeves the lower part of the Plodia interpunctella passing port. The Plodia interpunctella trap is rationally designed based on the
phototaxis of Plodia interpunctella,and has the advantages of high
trapping rate, high efficiency in prevention and control of Plodia interpunctella, no
pollution and sustainableness in use.
