In particular, the parasitic insects are parasitic wasps and the predatory insects are predatory mites and are contained in delivery capsules, which may degrade in the environment. The capsules comprise first orifices sized so that an insect cannot exit the capsules and second orifices sized so that an insect can exit the capsules. By creating the second orifices shortly before capsule delivery the number of insects reaching agricultural crops is increased.1/3 10 12 11 13 FIG. 1
