Studies on entomopathogenic nematodes in Brazil: past and future

Abstract

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.

Scirtothrips dorsalis E PROSPECÇÃO DE SEU DESENVOLVIMENTO EM CONDIÇÃO TÉRMICA DE DOIS CÓRREGOS, SP

“…Foram descritas 11 espécies e 56 linhagens de NEPs em território nacional, as quais têm mostrado potencial para o controle biológico, como é o caso da espécie Heterorhabditis baujardi LPP7 (Rondônia-BR) (DOLINSKI et al, 2017). A linhagem H. baujardi LPP7 foi utilizada em um trabalho de campo realizado pela pesquisadora Cláudia Dolinski, que implementou um programa de manejo do gorgulho da goiabeira (Conotrachellus psidii) com produtores de Cachoeira de Macacu, Rio de Janeiro-BR.…”

“…Os resultados para a utilização de NEPs no Brasil são promissores, contudo, a falta de incentivo financeiro debilita as pesquisas e retarda o avanço do país para o emprego desses bioagentes do controle de pragas de importância agrícola, médica e veterinária (DOLINSKI et al, 2017).…”

Association of Heterorhabditis amazonensis and Beauveria bassiana aiming the control of Hypothenemus hampei

“…Among other methods that can be applied in the control of coffee borer, the use of biological control can be considered potential, as long as crop management practices are taken into account. Entomopathogenic nematodes (Nematoda: Rhabditida) from the families Heterorhabditidae and Steinernematidae are potential pest control agents (Dolinski et al, 2017). According to Divya and Sankar (2009), the application of nematodes to bored fruits that fall on the soil Coffee Science, 15:e151779, 2020 helps control the pest insect.…”

Control potential of Heterorhabditis amazonensis (Rhabditida: Heterorhabditidae) in avocado borer, Stenoma catenifer (Lepidoptera: Elachistidae)

“…Entomopathogenic nematodes are considered promising biological control agents, particularly effective when applied to insects that inhabit or whose larval stage occurs in the soil (Dolinski et al, 2017). The use of these organisms to control S. catenifer pupae may be an alternative to pest management, considering that the pupae remain in the soil and that the perennial environment formed by the areas established with avocado favor the establishment of nematode populations.…”
