A delivery device and system to supplement CO.sub.2 in an underwater environment without the need for electricity or the use of compressed CO.sub.2. The device consists of a container containing a biological organism such as mycelium and including an exit portal for CO.sub.2 to enter the underwater environment. The device may also incorporate a separation device to delay and control the flow of CO.sub.2. The system requires the device to be held in place through a securing point in the underwater environment. The minimum requirements for the device are described, but in certain instances it will be preferably used with a double-bag or an outer shell housing to protect or aesthetically conceal the placement underwater. The use of this device and system to supplement carbon dioxide in water will span many industries and applications. It will assist with mosquito trapping. It will also supplement CO.sub.2 in underwater growing environments.

A device for controlling at least one insect bait station, in particular for insects harmful to humans, animals and plants, in which the bait station is provided with: at least one container provided with an insect entrance opening, the container containing bait and being at least partially transparent or translucent, a lighting device lighting the inside of the container but located outside same, a telecommunication module and a printed circuit comprising, inter alia, a memory and a processor connected to said telecommunication means. The device comprises an optical sensor essentially opposite the lighting device, and connected to the printed circuit, which measures the general opacity caused by the insect(s) in the container, the corresponding value being transmitted for processing and analysis of the status of the bait station.

The invention relates to methods of trapping a pest, said method comprising providing ferromagnetic particles for ingestion by the pest, and trapping the pest using one or more magnets, wherein a trapped pest has ingested and internally accumulated an amount of the ferromagnetic particles sufficient to permit immobilization of the pest using said one or more magnets. Devices for use with the methods of the instant invention are also disclosed.

A device for trapping damaging flying insects, including a device for diffusing an attractive gaseous cocktail, of which the composition is suitable for attracting insects, a suctioning device having an orifice for suctioning an air flow containing the insects attracted by the attractive cocktail diffused, a trap arranged with the suctioning device, and a chassis containing a gas source, which gas is a component of the attractive gaseous cocktail, where the optical insect counter includes a series of parallel deflectors installed through the suctioning orifice, a luminous barrier composed of a light transmitter and a light receiver being installed in each interval between said deflectors.

A universal insect trap having multiple points of entry is described being capable of capturing various types and sizes of insects. The universal insect trap may be used to capture and preserve target species such that genomes can be analyzed for specimens, which is beneficial in determining infection rates, strains of a vector or a pathogen, identifying associated microorganisms, determining or monitoring natural enemies, etc. The universal insect trap can include a base having a cone-shaped body, where the base includes a sloped surface. Further, the universal insect trap can include a dome portion and a trap portion. The trap portion can include an annular ring, a mounting portion, a vial, and an aggregation pheromone positioned in the trap portion, where the aggregation pheromone is one that emits a predetermined amount of pheromones over time to attract at least one predetermined type of insect.

The invention concerns a selective capture cage (20) for hymenoptera comprising a box having a bottom (201) and at least three walls, at least two walls of which each have an opening for the circulation (22) of scents, each circulation opening (22) of scents comprises a porous plate (21) covering the circulation opening (22) of scents, said porous plate (21) comprises a funnel section having a large base and a small base, the small base comprises at least one selective passage opening (212) and the small base is placed towards the inside of the capture cage (20), characterized in that: the passage opening (212) comprises at least a limiting passage section is comprised between 7.0 and 9.0 mm, preferably 7.21 mm; and in that the limiting section for passage of the pores of the porous plate (21) is smaller in size than the passage opening (212).

A pest detector includes: a first electrode; a second electrode that is arranged to face the first electrode; an electric field generator that generates an electric field in a gap between the first electrode and the second electrode; an imager that images at least the first electrode; and a hardware processor that determines an attaching state of insect pests that can be attached to the first electrode, based on an image captured by the imager.
