Attack by the coffee berry borer Hypothenemus hampei causes significant damage to coffee crops because it affects the quality of the coffee fruit during different developmental stages, which results in production losses. Control of the borer is difficult owing to its cryptic behavior and the fact that it spends its entire life cycle inside the coffee berries. This makes it difficult for natural enemies to reach it, as well as for it to come into contact with chemical insecticides. The objective of the present study was to select and evaluate the virulence of entomopathogenic nematodes (EPNs) on the coffee berry borer H. hampei and their compatibility with the insecticide cyantraniliprole under laboratory conditions. Initially, the pathogenicity and virulence of 16 isolates of Steinernema and Heterorhabditis towards coffee berry borer larvae and adults were evaluated. The most virulent isolates to both larvae and adults were determined by topical inoculation tests in coffee fruits (berries) infested by the insect, using a concentration of 100 infective juveniles (IJs)/fruit. The same isolates were also evaluated for viability and infectivity when combined with cyantraniliprole. The isolates S. feltiae (IBCB-n 47) and Heterorhabditis amazonensis (GL) displayed the highest virulence towards adults (54% ResumoA broca-do-café Hypothenemus hampei causa significativos prejuízos a esta cultura, pois seu ataque afeta a qualidade dos frutos de café em seus diferentes estádios de desenvolvimento e consequentemente leva a perdas na produção. O controle é dificultado devido ao seu comportamento críptico, uma vez que passa todo o ciclo dentro dos frutos de café, dificultando a ação de inimigos naturais, bem como o contato com inseticidas químicos. O objetivo deste estudo foi avaliar a virulência de nematoides entomopatogênicos (NEPs) sobre a broca-do-café H. hampei e a sua compatibilidade com o inseticida ciantraniliprole em condições de laboratório. Inicialmente, foram avaliadas a patogenicidade e virulência de 16 isolados de Steinernema e Heterorhabditis para larvas e adultos de H. hampei. Os isolados mais virulentos para larvas e adultos foram utilizados no teste de inoculação tópica em frutos de café infestados pelo inseto, utilizando uma concentração de 100 juvenis infectantes (JIs)

“…As a result of these tests, S. brazilense was found to be the nematode with greatest potential for controlling S. levis [16,24,28,100] . They also performed studies demonstrating the potential of EPNs to control Bradysia mabiusi (Lane) (Diptera: Sciaridae), an important pest of ornamental plants and other plants for cultivation in protected areas, with promising results [30] .…”

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.

“…Steinernema and Heterorhabditis species (Rhabditida: Steinernematidae/Heterorhabditidae) (Smits, 1996) are efficient against Curculionidae (Manachini et al, 2013). Steinernema and Heterorhabditis genera were virulent to Sphenophorus levis Vaurie (Coleoptera: Curculionidae) adults (Giometti et al, 2011). Gonipterus platensis larvae and adults feed on leaves and pupate in the soil when they may have contact with entomopathogenic nematodes.…”
