“…1). Leite et al (2005), by evaluating the use of some EPN strains against the root spittlebug M. fimbriolata, applied 2,000 IJ/mL on nymphs of the fifth instar in Petri dishes and found virulence of 100, 98 and 96% for the strains Heterorhabditis sp. (CB-n5), Steinernema sp.…”

“…After selecting the most virulent strain against M. fimbriolata in the laboratory, Leite et al (2005) tested its efficacy in the field at different concentrations, and found that Heterorhabditis sp. provided a maximum nymph mortality of 70% against spittlebug, regardless of the tested concentration.…”

“…Five nymphs were placed in each Petri dish (9 cm) lined with filter paper, and then 1 mL of an aqueous suspension of 2,000 infective juveniles/mL of each EPN strain was applied separately, as well as 1 mL of distilled water, according to the routine employed by Leite et al (2005), therefore forming nine treatments (strains) with ten repetitions each (totaling 50 nymphs per treatment), along with one control group to make sure that nymphs were free from previous contact with nematodes and that deaths occurred exclusively because of the treatments. The dishes were then closed with plastic film and stored in a climate-controlled chamber at 25ºC, 70% RH and 12-hour photophase.…”

The spittlebug can seriously limit the production of forage, and the use of chemical products to control insect pests is costly and can harm the environment. Thus, there is a need to reduce the reliance on chemical agents by developing new strategies. The virulence of nine strains of entomopathogenic nematodes (EPNs) to spittlebugs was investigated under laboratory and greenhouse conditions. Fourth/fifth-instar nymphs of Mahanarva spectabilis were exposed to EPNs in the laboratory and the most virulent strains were applied on the nymphs in the greenhouse at concentrations of 2,000 and 4,000 EPNs/mL. The efficacy of the pathogenic agent was confirmed by the dissection of dead hosts. All the tested strains were pathogenic to the M. spectabilis nymphs in laboratory, particularly Steinernema carpocapsae, S. feltiae, S. riobrave and Heterorhabditis amazonensis RSC1, each of which caused nymph mortality higher than 80%. The concentration did not influence the efficiency of the strains, and those selected in the laboratory had similar efficiency in the greenhouse, except for S. carpocapsae, which was not as effective as the others. Entomopathogenic nematodes can be included in integrated pest management programs to M. spectabilis.

HIGHLIGHTS• Lauro Travassos in 1927 created genus Steinernema.• Two new species of entomopathogenic nematodes were described.• Studies on ecology, biology, production, formulation and application of native species have been carried out since 2000. ABSTRACT:In Brazil, the first study with entomopathogenic nematodes (EPNs) was conducted by Lauro Travassos in 1927, when he created the genus Steineria, that latter was changed to Steinernema. After important meetings and courses, there was a great development of EPNs research in various states by different research groups in Brazil. Many EPN species were isolated throughout the country and two new species described: Heterorhabditis amazonensis and Steinernema brazilense. The behavioral aspects, life cycle and pathogenicity of native EPNs were analyzed. Also their persistence and survival in the soil and the biotic and abiotic factors that may affect their efficiency as biocontrol agents. Due to the particular native species characteristics, production, formulation and application technologies were developed for them. Here in we summarize main Brazilians studies in different areas using EPNs. This is the first review on the subject in Brazil.Keywords: biology, ecology, behavior, production, formulation.Cite as Dolinski C, Monteiro C, Andaló V, Leite LG.
