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).本研究采用同质园实验设计（common garden design），以三个远缘蛾类物种为研究对象，选取其分布范围覆盖芬兰北部至格鲁吉亚（高加索地区）的种群作为实验材料，探究了反映固有免疫（constitutive immunity）的两项参数——酚氧化酶（phenoloxidase，PO）活性与溶菌活性（lytic activity）——的种群间差异。
