Abstract
In 2015-2016 years for the purpose of studying the most acceptable methods of eradicating foci of melon flies, the effectiveness of chemical and agro technical measures in field conditions of the Kyzylorda region of the Republic of Kazakhstan were determined. Practical experience in the application of various phytosanitary measures for the localization and elimination of the melon flies foci was summarized. The principal role in limiting the further spread of the pest has been assigned to strict observance of quarantine phytosanitary measures. The effectiveness of agro technical and chemical measures applied against the melon flies has been assessed. The elements of the melon flies mass reproduction technology have been developed, including the collection of melon fly puparia in nature, their delivery to the laboratory, storage, emergence of flies from puparia, feeding, reproduction and obtaining laboratory population. The most optimal dose of radiation has been established for the treatment and release of sterile males.
