The survey shows that the Malaysian public generally supports new technologies such as Bti, believing that as long as it helps reduce dengue fever is a good measure. A questionnaire for Kuala Lumpur residents found that more than 80% of respondents supported using biological methods to prevent mosquitoes, while less than 10% explicitly opposed it (Rusly, 2024). In contrast, some Indonesian communities have shown more obvious hesitation about similar measures. Taking the Wolbuck symbiotic mosquito project in Yogyakarta from 2016 to 2017 as an example, although the final experiment proved that the technology reduced the number of dengue fever by 77%, it still encountered a certain degree of public doubt and opposition during the initial push. Some community leaders were worried about whether "release of insects will cause other diseases", and local media mistakenly reported Wolbuck mosquitoes as "GMOs", which caused residents to panic, and some groups even petitioned to demand the suspension of the project. Later, the project team gradually reversed public opinion through a large number of community meetings and household-by-household interviews. The Indonesian public’s initial resistance to biological control is stronger, reflecting a vigilant attitude towards unfamiliar technologies in culture and misunderstandings caused by inaccurate information (Tan et al., 2021). 5 Risk Communication and Information Transparency 5.1 The role of government and scientific research institutions in information dissemination Government departments and scientific research institutions assume the main information dissemination responsibilities in the implementation of Bt public health measures, and their communication strategies directly affect the public's understanding and support of the measures. As policy makers and executors, governments need to actively and transparently disseminate scientific knowledge, security and expected effects of Bt technology to the public, and eliminate doubts caused by information asymmetry (Ingabire et al., 2017). Shi Xinling and Wang Jianming (2022) pointed out that in public health emergencies, effective risk communication by the government should be based on timely and transparent sharing of all relevant information to enhance public trust. Similarly, for Bt measures, the government has the responsibility to timely publish key information such as test data, expert evaluation conclusions and authoritative organization certification, so that the public can understand the scientific basis and decision-making process for taking the measures. Scientific research institutions and experts also play the role of "source of knowledge" in risk communication. Scientific researchers can explain the mechanism and safety of Bt technology to the public through media interviews, popular science lectures, community lectures, etc., and answer questions of public concern in popular language. Research shows that when experts participate in communication, the public is more likely to accept professional opinions and adjust their views. For example, in the Gene-Driven Mosquito Project in Burkina Faso, local scientific research institutions organized scientists to enter villages and households to popularize science, which gave villagers a rational understanding of project risks and gradually changed from initial opposition to support (Trapsilawati and BlondineCh., 2010). This shows that expert discourse has unique advantages in building public trust. 5.2 Construction of information asymmetry and public trust Information transparency is the cornerstone of building public trust. The public often judges the risks and benefits of new technologies based on limited information and their own experience, and tends to adopt the most conservative attitude, namely distrust and boycott when they feel that information is insufficient or is concealed. For example, a certain place suddenly carried out Bti disinfection in the community without sufficient information. Residents panic because they did not understand in advance, thinking that a bacterial epidemic had occurred or the government was conducting dangerous tests, resulting in panic and complaints. This lesson shows that asymmetric information creates public misunderstandings, which in turn weakens trust in the government. Some research models point out that there is a causal relationship between government trust and risk perception: lack of trust and insufficient information communication will enhance public risk perception and change their attitude towards acceptance. Through questionnaire analysis, Huang Yihui found that transparent government
