Regarding the negative effects of overuse of pesticides on human health and the environment, in recent years, sustainable and green methods for pests control especially biological control have been considered by many researchers. However, due to the existence of various barriers, the process of adoption and usage of biological control methods is very slow among farmers. Given the importance of the subject, the main purpose of this study was to analyze farmers’ barriers in using Habrobracon hebetor to control tomato Heliothis spp. in Tarom County. Methodologically, this study was a descriptive-correlational research. The statistical population of the study was 1666 tomato producers in Tarom County in Zanjan Province. Based on the Bartlett et al. (2001) formula, 330 producers were selected by the stratified sampling method for doing the study. A research-made questionnaire was used to collect the data. The validity of the questionnaire was confirmed by a panel of experts and specialists. A pilot study was conducted to establish reliability of the instrument, which the calculated Cronbach alpha's coefficient for the main scale of questionnaire was appropriate (above 0.75). Collected data were analyzed using the SPSSWin22 software. The results of a factor analysis revealed that the farmers’ barriers in using Habrobracon hebetor to control tomato Heliothis spp. in Tarom County were categorized into five factors including, financial-economic barriers, psychological-social barriers, cognitive-informational weakness, supportive weakness and technical constraints and these factors, in total, explained 68.73% of variances of the barriers.

The main purpose of this study was analyzing the relationship between agricultural heritages and environmental sustainability of tourism. Statistical population of the study was rural households in Baghmalek and Izeh township located at Khuzestan province (N=484). Sample size determined via sample size table of Bartlett et al. (2001). (n=218). The proportional stratified sampling method was used for the study of samples. The research instrument was a questionnaire. Content validity of questionnaire revised and verified by a panel of experts. Also, values of discriminant validity (AVE), Cronbach’s Alpha and composite validity were desirable. Results of confirmatory factor analysis showed that agricultural heritage has a positive and significant effect (p value=0.01) on the environmental sustainability of tourism. So that agricultural heritage and its components (tangible and intangible heritages) explained 21.3% variation of environmental sustainability. Therefore it is necessary that authorities, planners, and all stakeholders always consider impacts of rural tourism development on cultural heritage and local communities in historical cities and surrounding areas of agricultural heritage sites.
