Abstract

Entomopathogenic nematode (EPN) occurrence in soil from natural areas and crop field edges from La Rioja (northern Spain) was compared using two insects as baits: Galleria mellonella (Lepidoptera: Pyralidae) and Spodoptera littoralis (Lepidoptera: Noctuidae). Both insects trapped Steinernema feltiae, S. kraussei and S. carpocapsae, with G. mellonella being more efficient than S. littoralis recording 5.4 and 2.6% of positive soil samples, respectively. EPN recovery frequency and abundance obtained with G. mellonella were not statistically different between natural and crop field edges values; however, S. littoralis was more successful trapping EPNs from crop field edges. Statistical differences were observed for recovery frequency recorded by both hosts in natural areas. Significant differences in larval mortality between both insects were not observed. The use of S. littoralis in entomopathogenic nematode surveys is discussed.
