| Abstract:
This study investigated greenhouse owner’ s behavioral intentions with regard to use of biological control methods. The Theory of Planned Behavior (TPB) was used for implementing this study, as it is one of the most widely used practical theories for investigating the relationship between attitude and action. The population of this research consisted of Greenhouse owners (N=300) in Bandar Abbas district. The samples were selected through random sampling of greenhouse owners (n= 110) in Bandar Abbas. The face validity of the questionnaire was approved by a research staff at Ramin agriculture and Natural Resource University. Questionnaire reliability also was confirmed through a pilot study by Cronbach alpha (0. 68-0. 83). Results indicated that attitude, perceived behavioral control and subjective norms were significant predictors of intention. Results also revealed that the greenhouse’ subjective norm was the main predictor of their intention to use biological control methods. This study provided a justification for using attitude, perceived behavioral control and subjective norms dimensions in policy and decision making that intend to encourage greenhouses owners to use biological control methods.
