Abstract
The mean relative density of field-counted sweep-net samples (y) of Empoasca fabae (Harris) may be expressed as a quadratic function of laboratory-counted sweep-net samples (x) by the relationship y – O.75(x) – 0.ll (x2) within a low-density range and when using to-sweep samples. The efficiency of a field-counted density estimate, defined as a percentage of the laboratory-counted density estimate, decreased as density increased. Pest management decisions were similar, whether based on field- or laboratory-counted sweep-net samples of adult potato leafhoppers.This publication has 2 references indexed in Scilit:
