代表性成果介绍

本团队主要研究领域为病媒生物学。2014年以来，围绕病媒生物的生理生化、天然免疫、抗病性机制和新型杀虫剂的研发，研究成果主要体现为以下几个方面：

1. 开展已知杀虫剂及靶标的深入研究可以了解抗药机制，有助于找到抗药性解决方案。本团队和国外同行合作首次解析了蚊虫的杀虫剂靶标，乙酰胆碱酯酶的晶体结构，鉴定了蚊虫多杀菌素和伊维菌素的作用靶标。

2. 蚊虫表皮合成和黑色素代谢相关酶的功能研究。本团队已成功搭建了蚊虫CRISPR/Cas9系统和RNAi技术平台，基于前期研究，主要对媒介昆虫的表皮合成和黑色素代谢相关酶类进行生理生化分析、功能研究，如芳烷基胺 N-乙酰转移酶、酚氧化酶和DOPAL合成酶等，探讨蚊虫的天然免疫机制。

3. 新型杀蚊制剂的研发。本团队成功研制出长效杀蚊虫制剂，多杀菌素微球缓释片，可用于蚊虫幼虫的防控（见下图，Pest Management Science封底）。本团队还通过RNAi干扰方法发现某些蚊虫表皮合成酶和结构蛋白或与蚊虫的发育密切相关，或对早期蚊虫具有致死性。由此，认为这些基因对蚊虫的生存极为重要，可将这些靶标基因应用到蚊虫的生物防控。关键问题是合适的环保的表达载体。目前已授权一项专利：大肠杆菌表达的蚊虫dsRNA，用甲壳素做成纳米颗粒。

4. 动物病原诊断与检测新技术的研究建立了一种由纳米材料ZnO结合PCR的检测方法，首次将纳米ZnO技术与PCR结合，以实现更高效省时的检测巴贝斯虫等原虫的感染情况，为这类疾病的快速诊断提供了技术支持。同时，还通过把一个简单、经济且易携带的LAMP 盒与智能手机连接起来，从而开发出一种针对寄生虫媒介传播疾病（例如犬埃立克氏体和犬肝簇虫）的检测系统。
