Problems solved by technology

[0002] The distribution and migration characteristics of stored insects in stored materials are mostly collected through field sampling at present. This work requires a lot of manpower and material resources. It is difficult to obtain detailed information such as the time dynamics of migration behavior, and it is not convenient. Investigate its response to changes in various environmental conditions
Mao Hanping and others designed the "Storage Pest Detection Method and Device Based on Near-infrared Hyperspectral Imaging Technology", which can use recognition software to automatically detect storage pests in grain undersize; Yang Ying et al. Grain Pest Detection and Identification Method and System", which can use video analysis software to detect and identify grain insect areas; Fu Jianping's "Controllable Impurity Stored Grain Pest Detection Device" is used for impurity-free detection of stored grain pests in grain piles The "stored grain pest monitor" designed by Shen Dong et al. can observe the pests entering the monitor in the grain pile. The above four methods are not designed for the purpose of dynamic analysis of vertical migration of stored insects, but focus on the pests. Recognition and counting, and the system is more complicated, and the implementation cost is higher
The "experimental device for aquatic animal habitat water layer and vertical migration behavior" designed by Li Yanhua et al., its working method is not suitable for related research on stored insects

Embodiment 1

[0014] In a hollow vertical cylinder formed by stacking several smooth ring layers, fill feed, grain or other silty or granular materials according to the purpose of investigation. The test insects can be used as the initial layer in any ring layer. When using a collection box to collect samples, start from the top layer, attach the collection box to the ring layer of the second layer above, push the ring layer of the first layer into the collection box horizontally, and then pour it into the sieve tray Separate the test insects from the filler; repeat this step from top to bottom to obtain the distribution data of the test insects in each ring layer within a specified time, and analyze the characteristics of their vertical migration time dynamics and aggregation sites based on this.

Embodiment 2

[0016] according to figure 1 As shown, the present invention is composed of a ring layer 1, a support cylinder 2, a collection box 3 and a sieve tray 4, etc., wherein the support cylinder 2 is formed by buckling two semicircular cylinder bodies, and the bottom of the support cylinder 2 is provided with The ring base 5; the ring layer 1 is a hard ring body with a smooth inner wall, and several smooth ring layers 1 are stacked to form a hollow vertical cylinder, which is set in the cylinder cavity of the support cylinder 2, and the cylinder is filled according to the purpose of investigation Feed, grain or other silty or granular substances, the test insects can be used as the initial layer in any ring layer, and migrate by themselves under the provided environmental conditions; one side of the collection box 3 is a semicircle sunken inward, and The outer wall of the ring layer 1 is closely matched, and the height of the collection box 3 is equal to that of the ring layer 1; wh...

Abstract

The invention provides a method and a device of investigation on vertical migration characteristics of stored-product insects. Fodder, grain or other powdered or particulate materials are filled in a hollow vertical cylinder formed by a plurality of stacked smooth circular layers according to investigation purposes, and test insects are allowed to start self-migrating from any circular layer under the given environmental conditions. When a collection box is used for collecting and sampling, the collection box is attached to the second circular layer above from the uppermost layer, the first circular layer is horizontally pushed into the collection box, and the test insects are poured into a screen plate to be separated from the filling. By repeating the step from top to bottom, distribution data of the test insects in the circular layers can be obtained within a specific time, and the characteristics of vertical migration of the test insects, such as time dynamics, gathering position and the like are analyzed according to the distribution data. The device is simple in structure, low in cost, convenient, practical and accurate in data.

Description
