experiment example 1

[0032] Experimental example 1. The selection of the wavelength of the light source used by fluke lamp beads

[0033] Among them, the test insect used in the experimental process, the Indian grain moth, was collected from Zhengzhou, Henan, and was used in the Ecological Research Office of Stored Grain Pests of Henan University of Technology with crushed peanuts, red dates, and millet at (32 ± 1) ° C, 70% ± 5% Raised under RH conditions for multiple generations.

[0034] There are many factors that affect the phototaxis behavior of the grain moth, among which the wavelength of the light source is the most important. Selecting a light source with a specific wavelength range is conducive to targeted trapping of pests, thereby improving trapping efficiency. Due to the nature of insects, they have different tropism or avoidance to different light sources, and different insects also have different choices for the tropism of light waves. The Indian grain moth shows different tropism...

experiment example 2

[0041] Experimental example 2. Selection of fan motor

[0042] Two kinds of motors were selected for the test, one is a 60W motor, the rated voltage is 220V, the rated frequency is 50Hz, the input power is 60W, the rated speed is 1200r / min, and the size parameters are 70mm, 70mm and 90mm; The rated voltage of the motor is 12V, the speed is 15000 rpm, and the size parameters are 21mm, 21mm and 27mm respectively.

[0043] Experimental process: A simple small experiment was done to determine whether the motor is suitable for the use of the trap. The experiment was carried out using a cylindrical hollow cylinder, and a fan was placed inside the cylinder. Several Indian grain moth adults were released at one end of the cylinder, the fan was started, and the experimental results were observed.

[0044] Experimental results: The 220V motor can suck almost all the moths into the cylinder, and the 12V motor has less wind power than the 220V motor, and the moths sucked are not as many ...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of grain safety storage, and mainly relates to the prevention and control of stored grain pests, in particular to an Indian grain moth trap. Background technique [0002] The Indian meal moth, also known as the Indian meal moth, is a widely distributed Lepidoptera Lepidopteridae insect, and is an important harmful pest of stored grain and its processed products. Adults are good at flying and are prone to repeated infection, so it is difficult to prevent and control in a large area. The larvae prefer coarser flour and other processed products. The damage to the complete grain is limited to the embryo, and a film will form on the surface of the grain pile. The larvae feed on a variety of foods such as grains, legumes, nuts, dried fruits, dried flowers, dried vegetables and some spices. In addition to destroying commodities by eating, larvae also affect food quality through spinning nets, causing economic los...
