Genetic differentiation of the green spruce aphid ( Elatobium abietinum Walker), a recent invader to Iceland
Abstract 1 The RAPD method (Random Amplified Polymorphic DNA) was used to investigate genetic diversity of the green spruce aphid, Elatobium abietinum Walker, a pest introduced recently to Iceland. 2 This aphid in Iceland comprised two polymorphic populations, one in the east and the other in the we...
