Certain insect pests may be controlled by introducing sterile males into the breeding areas of the wild insects. The method usually involves the release of large numbers of laboratory-reared insects that have been sterilized by gamma radiation. Matings between the sterile males and wild females result in sterile eggs. The wild population is consequently reduced, the rate of reduction being directly proportional to the ratio of sterile to fertile males. One important requirement of this method of control is an effective procedure for releasing the sterile insects. The procedure should be economical and result in distribution of the insects, with out injury, at controllable rates. Basically there are two types of release
