Formulation of two native entomopathogenic nematodes at room temperature
Journal of Biopesticides 5 (Suppl.), S23-S27
Abstract: In many commercial EPNs-based biopesticide companies, formulations ranging from the impregnation of EPNs on artificial sponge to highly advanced granular formulations have been developed. Major challenges have included the development of room-temperature shelf stability, ease of use, and contamination control. The aim of this work was to evaluate the suitability of two indigenous EPNs, Heterorhabditis bacteriophora (BA1) and Steinernema carpocapsae (BA2), for formulation and storage on Hydrogel, Kaolinite and Calcium Alginate at room temperature. The survival and virulence of both nematodes in the three formulations were discussed. Comparing the two nematodes, it was found that the storage potential of BA2juveniles was only superior to that of BA1 in case of formulation with Calcium alginate. The pathogenicity of the two EPNs in the three formulations was tested against the wax moth, Galleria mellonella. It was concluded that BA2 was more virulent than BA1 to the larvae of the wax moth, G. mellonella in all tested formulae.
