Latitudinal gradient in insect immunity

We studied among-population differences of two parameters reflecting constitutive immunity – phenoloxidase (PO) and lytic activity – using common garden design on three distantly related moth species represented by populations ranging from northern Finland to Georgia (Caucasus).本研究采用共同花园实验设计（common garden design），以3个远缘相关的蛾类物种为研究对象，其种群分布跨度从芬兰北部延伸至格鲁吉亚（高加索地区），探究反映组成型免疫（constitutive immunity）的两项参数——酚氧化酶（phenoloxidase，PO）与溶菌活性（lytic activity）的种群间差异。
