A resin composition contains an ethylene-vinyl alcohol copolymer (A) in which an ethylene unit content is from 10 to 60 mol %, a hindered amine-based compound (B) having a 2,2,6,6-tetraalkylpiperidine ring structure and having an alkoxy group bonded to a nitrogen atom in the structure, and a hindered phenol-based compound (C) having an ester bond or an amide bond. The resin composition contains 0.1 to 5 parts by mass of the hindered amine-based compound (B) and 0.2 to 5 parts by mass of the hindered phenol-based compound (C) with respect to 100 parts by mass of the ethylene-vinyl alcohol copolymer (A), and a mass ratio (C)/(B) is from 0.2 to 3.6.

A device for mosquito repellents, including a support structure having a first end arranged to be positioned on a surface, and a second end opposite the first end, the distance between the first end and the second end defining a height H of the support structure. The device further includes a first plate arranged at the second end of the support structure perpendicularly to a direction of height of the support structure, the plate being void of openings and suitable for receiving a heated mosquito repellent. The device still further includes a fan attached within the support structure, between the first end and the second end of the support structure, to blow air from the first end towards the second end of the support structure and the first plate, and means for operating the fan. The size and shape of the first plate is such that it covers the fan, when seen from the second end of the support structure in the direction of height of the support structure.

A beehive treatment system utilizing an oxalic acid vaporization process is used to treat honey bee colonies against the adverse effects of infestation by the Varroa Mite pest. The beehive treatment system includes units having heating chambers configured to vaporize crystalline oxalic acid. Implementations include an air-flow pre heat circuit to prevent crystallization of oxalic acid when treating a beehive.

Disclosed herein are robotic devices which traverse a pre-defined coverage area in order to capture and eradicate ticks in the area. A vacuum mechanism provides a suction force for pulling ticks into the device through a frontal opening, after which the ticks are captured in a receptacle and crushed by at least one rotating arm. In certain embodiments, the devices include heat strips near the frontal opening of the device that mimic the human body temperature. Additionally, the device can include carbon dioxide emitters that pass carbon dioxide to the receptacle or through the frontal opening to increase attraction of ticks.
