Abstract:
A method of delivering ichneumon flies over an extended surface area for agricultural pest control, wherein said method comprises the steps of:a) providing a number of containers, each of said containers consisting of a plurality of ichneumon fly eggs and two biodegradable plastic parts (2, 3), said two biodegradable plastic parts (2,3) having inner walls (19) with said ichneumon fly eggs (10) adhering to said inner walls, and wherein said two biodegradable plastic parts (2,3) are connected with each other to form a closed container for the ichneumon fly eggs, except that at least one of said two biodegradable plastic parts (2,3) is provided with at least one emergence opening (13) that is sufficiently large enough so that said ichneumon flies hatching from said ichneumon fly eggs leave through said at least one emergence opening; b) dropping said containers over the extended surface area without destroying said containers; and c) leaving said containers on the extended surface area for a time sufficient for hatching of said ichneumon fly eggs and emergence of the ichneumon flies from said containers; whereby said ichneumon flies kill agricultural pests by deposition of further ichneumon fly eggs in eggs of said pests and said containers decompose leaving no residue.
