Enumerative and Binomial Sampling Plans for Armored Scale (Homoptera: Diaspididae) on Kiwifruit Leaves
The spatial dispersion of armored scale insects; greedy scale,Hemiberlesia rapax (Comstock); and latania scale,Hemiberlesia lataniae (Signoret), was investigated onkiwifruit, Actinidia deliciosa (A. Chevalier) C. F.Liang et A. R. Ferguson, leaves in New Zealand. A universaldescription for dispersion...
