A system and method of release and dispersion of genetically altered flies or other insects to control insect population. Disclosed is an apparatus designed to be carried by an aircraft which implements a method of insect population control. The apparatus features one or more removable fly chambers that contain fly containment cylinders. The fly chambers are seated upon one or more nesting chutes. A refrigeration system operates to physically retard the fruit flies. Once the flies have been successfully immobilized by the refrigerated air, they are 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.
