A system and method of release and dispersion of genetically altered flies or other insects to control insect population. The apparatus can be carried by an aircraft and includes removable fly chambers that contain fly containment cylinders. A refrigeration system operates to physically retard the fruit flies. The flies are then released from the fly containment cylinders and fall to the bottom of the fly chamber. Gates on the bottom of the fly chamber are opened manually or remotely to allow the refrigerated flies to fall through the nesting chute into the spiral release controllers. The spiral release controllers dispense the genetically altered flies into the exit chute. The genetically altered flies travel through the exit chute, fall to the earth below and mate with the population thus serving to decrease population by capitalizing on a weakness in the reproductive cycle of the fruit fly or other insect.
