A device (1) for trapping animal pests such as caterpillars, having a collar (2) which is designed to surround the trunk of a tree (3), the collar (2) including a substantially annular walkway (4) that extends substantially in a first plane (P1) that is intended to be oriented horizontally. Joining means (31) including an arrangement (32) of flexible bristles (33) having a suitable density prevent the animal pests from passing between the collar (2) and the trunk of the tree (3).

A barrier section of a snake barrier includes an upright portion and an overhang portion. First and second support braces support the upright portion and the overhang portion. Each of the first and second support braces include an upright member supporting the upright portion and an overhang support member pivotably coupled to the upright member and supporting the overhang portion. The upright member defines a lay-flat-configuration hole and an erect-configuration hole. The first and second support braces each include a projection configured to be received by the lay-flat-configuration hole to position the overhang support member generally parallel to the upright member and configured to be received by the erect-configuration hole to position the overhang support member generally orthogonal to the first upright member.

In order to effectively apply semiochemical treatment products, a computer-implemented method is provided for generating an application scheme for a semiochemical treatment for controlling a harmful organism on an agricultural field using a mobile treatment device comprising at least one dispenser, the method comprising: a) providing information about an expected presence of the harmful organism for an upcoming period; b) providing, based on the expected presence of the harmful organism, a planned application timing of applying the semiochemical treatment for treating the harmful organism on the agricultural field; c) providing product data relating to a semiochemical product capable of targeting the harmful organism; d) providing, at least one of field data or environmental data at the planned application timing, wherein the field data is indicative of a field condition at the planned application timing and/or the environmental data is indicative of an environmental condition at the planned application timing; e) determining, based on the product data and the at least one of field data or the environmental data at the planned application timing, a minimum concentration of the semiochemical product for affecting a behaviour of the harmful organism; f) determining, based on the minimum concentration of the semiochemical product, a dose rate of the selected semiochemical product to be spread by the at least one dispenser into an atmospheric vapour forming a cloud which envelops crops on the agricultural field; and g) generating the application scheme based on the determined dose rate.

An anti-pest device for fruit trees and the like that prevents trees from being affected by crawling insect pests includes a rectangular sheet of electrical insulating material, which can adopt the shape of an inverted truncated cone or a cylindrical configuration around the trunk of the tree; a band of low-density foam under the sheet that adapts to the physiognomy of the bark, and deforms with the growth of the trunk, whereas the sheet includes a sector that is superimposed thereon and slides on it to adapt to said growth; a pair of parallel conducting wires, separated a distance according to the size of the body of the insect to be exterminated, subjected to a high difference in electrical potential by means of a power supply circuit, such that when an insect tries to get past them, it is automatically electrocuted.

A compound delivery device includes an integrally molded hygroscopic body having a hygroscopic glycerin soap base material, and different animal attractants/repellants. The integrally molded hygroscopic body has an external surface directly exposed to an external environment and configured to condense ambient moisture directly thereon. The compound delivery device also includes a support structure coupled to the integrally molded hygroscopic body, and to be coupled to an anchor body. The support structure extends within the integrally molded hygroscopic body. The integrally molded hygroscopic body is configured to sequentially release the different animal attractants/repellants in an area adjacent to the anchor body using the ambient moisture.
