Abstract
A comparison of the efficiency of Tullgren funnels vs. a wire sieve for extracting known numbers of late instar Chrysops hirsuticalhis Philip from soil samples ca. 5.1 cm thick by 0.093 m2 revealed that the sieve was more efficient when both high (20) and low (10) larval densities were used. The differences between replicates during funnel extraction were significant at high larval density (chi-square test, p=.034), which raises doubts about the reliability of this method for quantitative studies of larval tabanid populations.This publication has 1 reference indexed in Scilit:
