Screening of entomopathogenic nematodes to control Mahanarva fimbriolata (Hemiptera: Cercopidae)
Revista Colombiana de Entomología 37 (2), 198-202
Abstract: We aimed to screen entomopathogenic nematodes (EPNs) strains against the root spittlebug, Mahanarva fimbriolata. An assay was performed at laboratory in which nymphs of the insect were exposed to seven EPNs strains (Steinernema anomali, S. carpocapsae, S. feltiae, S. riobravis, Heterorhabditis amazonensis RSC5, H. bacteriophora HP88 and H. baujardi LPP7) under three concentrations (200, 400 and 800 EPNs/nymph). After the laboratory screening a greenhouse assay was carried out using the most pathogenic strains. Increasing concentration didn't increase nymph mortality at laboratory. The root spittlebug nymphs were susceptible to all strains, with 48% (S. carpocapsae) and 72% (S. feltiae) pathogenicity extremes. A decrease in efficiency was observed in greenhouse tests compared with laboratory tests.
