The management of carob moth is a complex and multidimensional process that is only possible when collective action takes place in the pest-affected areas. The non-participation in carob moth management has led to increasing pest problems which unless managed collectively, they impose a serious limitation on pomegranate production and endanger the future of pomegranate orchards in Arsanjan county, Fars province, Iran. The current study aimed to explore why collective action has not taken place, and grounded theory was found to be the most appropriate method, followed up by a structured survey to gain an in-depth understanding of what is happening and why. Qualitative data collected through interviews were analyzed using Straussian grounded theory procedures and techniques, and quantitative data obtained via questionnaires were analyzed using descriptive statistics. The analysis indicated that individual farmers' attempts to manage carob moth had limited benefit. The results revealed that inadequate and unsupportive institutions of all types (cognitive, normative and regulative) kept collective action from occurring. The main factors impeding the participation of the farmers in the management of carob moth were: unsupportive environment for agribusinesses, low income from pomegranate production, negative attitudes towards the government, lack of cooperative culture and prevalence of individualistic behavior, and inadequate knowledge about the pest among the growers. The categories and the relationships found among them assist stakeholders in understanding the root causes behind a lack of collective action in the pest management programs. The results provide powerful lessons for other participation projects and pest control interventions.

Conservation agriculture is an approach for managing agricultural ecosystems, improving productivity, increasing benefits and food security, and preserving resources and the environment. The core purpose of this study was to analyze the constructs affecting the intention to use conservation agriculture measures. For this purpose, protection motivation theory was applied as the theoretical framework. Validation of the model was done using a cross-sectional survey among Iranian farmers, and SMART PLS software was used to test the hypotheses. The results showed that the direct effects of the five constructs of perceived severity, perceived vulnerability, response cost, response efficacy, and self-efficacy were significant on the intention to use conservation agriculture measures. In addition, the variables of perceived severity, response cost, and perceived self-efficacy had significant effects on the fear of not using conservation agriculture measures. The results of the bootstrapping analysis indicated that the fear of not using conservation agriculture measures significantly mediated the effects of perceived severity, response cost, and self-efficacy on the intention to use conservation agriculture. The results of the present research help to develop protection motivation theory by defining new relationships between its variables and achieving a deeper understanding of these relationships. The results also can pave the way for social and psychological interventions in the field of adopting the principles of conservation agriculture in agricultural societies. Finally, the results of this research can be used as a decision-making tool and help for users and planners of behavioral changes to better identify the focus points and necessary strategies.
