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 device (10) for trapping and killing marine organisms (14) such as animal plankton, salmon lice and other parasites, comprises a body (12; 12′) configured for submersion in water (15). The body (12; 12′) comprises at least one light source (16) configured and controlled for attracting said marine organisms, and an internal cavity (20) having an opening (20′) for fluid communication with at least a portion of the water. The light sources (16) are arranged inside the cavity (20) and arranged and controlled to emit light waves through said opening and into at least a portion of the water. At least one positive electrode (24; 24′; 24″; 32) is arranged in the cavity and electrically connected to a low-voltage power source (26; 27; 30), and at least one negative electrode (15a) is arranged in the water and electrically connected to said power source (26; 27; 30). The invented device generates, by means of electrolysis with the water (15), chlorine gas (21) at or in a region near the at least one positive electrode, and the chlorine gas (21) reacts with water inside the cavity to form hypochloric acid and hydrochloric acid (31).

A light source device for trapping indoor adult Phycitinae, which is an adult moth belonging to subfamily Phycitinae, is configured to: emit an attracting light at a predetermined photon flux density; and form a guide path by the attracting light to guide the adult Phycitinae to a vicinity of an emission end of the attracting light in a region having a photon flux density lower than the predetermined photon flux density on a side lower than a height of the emission end of the attracting light

A solar powered lighting element with a simulated flame and an electric insect eliminator includes a lighting portion with a conducting grid and a light portion that simulates a flickering flame which are powered by a rechargeable battery that is recharged using a solar panel. One or more UV light elements are provided in addition to the flickering flame to attract insects.

An electrifiable projectile for an insect zapper gun is capable of killing a target insect at a distance from the user. The projectile includes a pattern of electric wires forming a front-facing conductive contact structure having a breadth sufficient to allow the projectile to intercept an insect when propelled in a forward trajectory toward an insect. When the projectile's pattern of electric wires comes into contact with the target insect, an electric charge on the projectile is transmitted to the insect rendering the insect deceased.

An intelligent Forcipomyia taiwana monitoring and management system comprises: a catching mechanism grabbing a to-be-identified target; a database storing a datum comprising pictures of a flying insect category; a model training module using the pictures to establish a training model; an image capture module shooting an image including the target; an identifying module selecting a first segmented region including the target by using YOLO detection framework technology, extracting a first identification feature from the target, and inputting the feature into the training model for deep learning to identify a flying insect category to which the target belongs and produce an identification result; a counting module recording a number of the target into the database; and a predictive tracking module obtaining a marked object based on the result marked with the target identified in the image, and using a Monte-Carlo category algorithm to track and predict the object.

An insect zapper device comprises a zapper element and a cleaning element. The zapper element comprises a base portion, a plastic housing on the base portion, electric coils on the plastic housing, and a power source to deliver energy to the electric coils. The cleaning element has a plurality of brushes and is slidable with respect to the zapper element to transport the plurality of brushes along the electric coils to dislodge dead insects.

The present invention provides an electrified garbage container cover that destroys insects that may attempt to access, or escape from a garbage container. The electrified garbage container cover frame is configured to fit in the opening of a garbage container enclosing or sealing the interior of the garbage container with the lower edge of the electrified garbage container cover. The electrified garbage container cover frame supports a mesh frame portion between the upper and lower edges, which supports an electrified mesh. The electrified mesh is capable of electrifying insects destroying them upon contact. The electrified garbage container cover also has a fastening mechanism supported by the frame, which is configured to attach the electrified garbage container cover to a garbage container. The electrified garbage container cover also has a power source which is able to provide electricity to the electrified mesh, and is capable of being recharged.

An insect zapper gun is capable of killing a target insect at a distance from the user. The zapper gun incudes an electrifiable projectile fired from a handheld base. When the projectile comes into contact with the target insect, an electric charge on the projectile is transmitted to the insect rendering the insect deceased.
