Abstract: The invention relates to an arrangement (11) having a hollow panel (1), for example a honeycomb panel, and a joint fitting (6). For the purpose of stable fixing, the invention proposes that the joint fitting (6) be inserted through a hole in a covering panel (3) of the hollow panel (1) and into a counterbore on the inside of the other covering panel (4) of the hollow panel (1). As a result, the joint fitting (6) is provided with stable support against forces in a radial direction, that is to say against forces acting in the plane of the panel. There can be inserted into the joint fitting (6), for example, an eccentric clamp (19) known per se, by means of which, as a result of rotation, a tension anchor (14) can be tensioned.

Abstract: The container for delivery of ichneumon flies consists of ichneumon fly eggs and two biodegradable plastic parts (2,3) that are interlocked with one another. The ichneumon fly eggs are stuck on an inner wall (19) of the container. The container (1) is provided with at least one emergence opening (13), preferably a slit, of sufficient size for emergence of the hatched ichneumon flies. This container is rigid and enables automatic filling and delivery of the ichneumon flies by dropping the containers from a magazine, for example using small airplanes or model airplanes. The container decomposes after the container has been ploughed into the ground. A method of agricultural pest control using the containers is also part of the invention.

Abstract: The container for delivery of useful organisms, especially ichneumon flies, consists of two dish-shaped parts (2, 3) that are connectable to one another. The container (1) is provided with at least one emergence opening (13) for the useful organisms and is made from a biodegradable material. This container is stable and enables automatic filling and delivery of the organisms from a magazine, for example using small airplanes or model airplanes. The container (1) is made from a biodegradable material that decomposes after the container has been ploughed into the ground.
