The spread of agricultural technological innovations is one of the main reasons for the social change in many agricultural areas in the developed world. Modern agriculture is characterized by rapid change and increased productivity due to the application of research results by agricultural scientists in agricultural colleges, research centers and agricultural experimental stations. The results of studies indicate that the increase in agricultural production was the result of the spread of agricultural ideas and practices developed and adopted by farmers. As the success of agricultural extension in the process of dissemination and delivery of agricultural technical recommendations to the farmers depends on the adoption of these recommendations and put them into practice in their fields, increasing their incomes and then increase their economic and social levels and thus achieve the progress of agriculture and the renaissance of society. The dissemination and adoption of agricultural innovations is a general goal and a key role of both the extension system and rural development programs. To achieve this goal, these two components have had to carry out a process of dissemination of new agricultural innovations and ideas to exclude the farmer and all beneficiaries of the rural population. As well as upgrading the methods of this production to save time and effort, in addition to taking into account the environmental dimension and rationalizing the consumption of natural resources. The interrelationship between agricultural extension and agricultural scientific research the research provides guidance on the results of research from new innovations and technological ideas that are applicable, while the extension provides research on problems and issues that require solutions and recommendations. The development meets the needs of the present without compromising the ability of future generations to meet their needs, thus achieving economic growth and preserving the quality of the environment. It balances the human needs and the surrounding environment, guarantees future generations a level of well-being and adopts a comprehensive development plan. And the reclamation of land where vertical expansion projects are going to increase the productivity of acres of different crops as well as horizontal expansion projects by reclamation and addition of new areas to increase the per capita agricultural area and face the growing population growth to meet development requirements and individual needs. Achieving agricultural development there must be an agricultural strategy for the sustainable use of natural agricultural resources, the development of agricultural productivity of the land and water units, the strengthening of the competitiveness of agricultural products in domestic and international markets through improved agricultural investment climate that improves the standard of living of the population and the reduction of rural poverty. Fruit crops are one of the most important crops because of their nutritional and economic importance, both at the level of domestic consumption and export. The fruit orchards in Egypt occupy about 1 million feddans. Citrus is economically important among the fruit crops. The cultivated area is 485940 feddans of the total area cultivated in the Republic. 9224835 acres) produce about 3.6 million tons (Central Department of horticulture,2016). Citrus is one of the most important fruit crops in all parts of the world. It has an economic importance. It occupies a major position in world trade, where it plays an important role in the economy of many countries in addition to its high nutritional value and consumer demand more than other types of fruits. In addition to the portability of transport, handling and storage, and due to the economic return of the citrus crop exports, there was a great emphasis on the use of modern methods and methods to improve the productivity of this crop and improve its efficiency. Rayya, total Egyptian citrus exports amounted to overseas markets during the year 2016 about 1.4 million tons compared to 1.250 million tons in 2015, an increase of 16%. The extension of agricultural activities and programs to meet the challenges and requirements of sustainable development, where the development of the rural population include changes in economic and technological aspects, and in order to achieve these changes requires rural acceptance and acquisition of new knowledge and requires appropriate decisions to establish integrated areas with opportunities to develop new patterns of work and production in a manner consistent with the available resources and needs of the population. In order for the agriculture sector to take a natural course in the development process, it was necessary to transform the traditional agricultural situation into the situation developed by the results of applied agricultural research, as well as the presence of the agricultural extension service, which works to communicate the results of research to farmers and convince them It will produce viable technology in various agricultural fields, including fruit fly control.
