莫纳什大学研究人员发现，全球80%以上的昆虫物种生活在热带地区，但这些地区的昆虫保护工作严重滞后1。研究表明，仅占全球20%的昆虫多样性知识来自热带地区，形成了明显的认知偏差1。这一差距在具体案例中更为突出——全球生物多样性信息库中26%的昆虫分布数据来自英国1，而对孟加拉国111项蝴蝶研究分析显示，仅34项发表在国际期刊上1。
由莫纳什大学全球变化生态实验室主任Shawan Chowdhury博士领导的研究团队指出，当前的"直升机科学"模式——即由发达国家科学家主导的外来研究——已难以满足热带地区的实际需求1。研究建议建立本地主导的研究体系，整合科学研究、博物馆记录、本地知识、公民科学和社交媒体数据来改进热带昆虫保护1。调查发现，Facebook上已包含孟加拉国169种受威胁蝴蝶物种中167种的记录1，这表明本地数据资源的可用性远超预期。
昆虫保护的紧迫性不容忽视——全球估计有1400万至3000万昆虫物种，大多未正式记录1，而昆虫为80%以上野生植物授粉，是60%鸟类的食物来源1。以孟加拉国为例，226种蝴蝶中仅1种在现有保护区系统中得到充分保护1。这项研究已发表在《生物科学》期刊1。
More than 80% of the world's insect species inhabit tropical regions, yet conservation efforts remain severely inadequate due to insufficient research knowledge about these ecosystems 1. A research team led by Dr. Shawan Chowdhury, director of the Global Change Ecology Lab at Monash University, found that while tropical areas house the vast majority of insect diversity, only 20% of global insect knowledge comes from tropical regions 1. The research, published in the journal Biological Sciences, highlights how current approaches rely on external expertise—termed "parachute science"—rather than building locally-driven research systems 1.
The knowledge gap has profound implications for biodiversity protection. Of an estimated 14 to 30 million insect species worldwide, most remain formally undocumented 1. Insects pollinate more than 80% of wild plants and serve as food for 60% of bird species, making their conservation critical 1. The Global Biodiversity Information Facility's insect distribution data reveals stark geographic imbalances, with 26% sourced from the United Kingdom alone 1. In Bangladesh, only 34 of 111 butterfly studies were published in international journals, yet Facebook contains records of 167 of the country's 169 threatened butterfly species 1. Most critically, only one of Bangladesh's 226 butterfly species receives adequate protection within the existing reserve system 1.
To address these gaps, Monash University researchers propose a comprehensive global framework integrating scientific research, museum records, local knowledge, citizen science, and social media data 1. The approach emphasizes dismantling external research models and establishing locally-led conservation systems capable of documenting and protecting tropical insect biodiversity 1.
