The aim of this research is to determine the knowledge level of some vegetable growers towards biological control of agriculture pests in the new lands in El-Behira Governorate. Research area was undertaken in West Nubaria  district- El-Behira Governorate. One hundred and seventeen vegetable growers were selected by using the proportionate random sampling technique (According to cultivated area). A survey method through face-to-face interview by using structured questionnaire was used to collect data and suitable statistical analyses were used. The findings show that:
- 87.2% of the respondents with moderately or fewer knowledge level to the biological control techniques.
- The main sources of vegetable growers' respondents' knowledge about biological control techniques were the ministry of agriculture and the agricultural engineers. And the major sources of agricultural information for them were agricultural pesticide and supplies traders, their own experience, relatives and neighbours.
- There are highly significant positive relationship at 0.01 level between dependent variable and educational level and testability of the innovations in the agriculture. And there are significant positive relationship at 0.05 level between dependent variable and the previous application of biological control, the number of years of application and the attitudes toward biological control.
- farmers respondents know very little knowledge about the natural enemies of vegetable pests such as using of Encarsia formosa parasitoid for controlling the white fly, Trichogramma spp. parasitoid destroys Tuta absoluta and other fruit Lepidoptran larvae, the use of parasitoid Aphelinus sp. and aphidius matricariae to control aphidus, when the number of plants infected with larvae on the vegetables the control will be done with the Beauveria bassiana fungi.
- The main problems which facing respondents are lack of experience and the implementation difficulties of the biological control techniques. And the need for increasing the effectiveness of the agriculture extension activities through technical training and encouraging farmers to develop positive attitudes toward agricultural production free of chemical pesticides in the research area.
