“…In this method, insects infected with nematodes are released in the field and serve as a source of IJs, which leave the insect cadaver and search for new hosts in the soil, thus controlling the target pest. To support this approach, we observed innumerous advantages in terms of EPN infectivity, dispersal, survival [96] . Del Valle et al [97] demonstrated that H. baujardi LPP7 released from G. mellonella cadavers reduced the number of guava weevils in an in vivo test, and that this application method permits good persistence of the IJs in the field (six weeks).…”

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.

“…The cadavers are another way to apply EPNs in the field (Shapiro-Ilan et al 2001Bruck et al 2005;Del Valle et al 2008a, b;Lacey et al 2010;Raja et al 2015). In this formulation, the insect cadaver serves as a reservoir to store the EPNs and then they are applied in the field.…”

“…Laboratory tests have indicated that this method of application produces a better distribution of the EPNs in the soil than that obtained with the aqueous solution (Shapiro & Glazer 1996), increases infectivity (Shapiro & Lewis 1999) and is more effective (Shapiro-Ilan et al 2003). However, it presents a drawback that during storage and transport the larvae can stick or break, which affects the effectiveness of the EPNs (Shapiro-Ilan et al 2001).…”

Cruz-Martínez H., Ruiz-Vega J., Matadamas-Ortíz P.T., Cortés-Martínez C.I., Rosas-Diaz J. (2017): Formulation of entomopathogenic nematodes for crop pest control -a review. Plant Protect. Sci., 53: 15-24.The different materials and methods used to develop biopesticides with entomopathogenic nematodes (EPNs) still limit the quality of the final product, reducing field efficacy and complicating application strategies. Therefore, the objective of this review is to identify priority areas to improve the EPN formulation process based on the scientific and technological research developed so far. The results show great progress in the EPN survival time, from 7 days to 180 days, through two types of formulations: water dispersible granules and calcium alginate capsules. Also, EPNs formulated and applied as insect cadavers showed higher efficacy for the pest control than the EPNs applied in an aqueous solution. We consider that the priority areas of research are: automated massive formulation and exploration of new additives with better properties that may lead to increase the infectivity in the field. It is concluded that the study of these aspects requires a systemic approach with greater involvement of the invertebrate physiology and systems modelling disciplines.

“…In addition, IJs stored as suspension suffer from certain intrinsic drawbacks: (i) post application, they undergo up to 30% mortality due to exposure to UV radiation; (ii) progressive reduction in infectivity with the use up of lipid reserves, and (iii) poor tolerance to desiccation stress 15 . In view of the above, we customized and adopted the relatively novel EPN-application technology of implanting H. indica-infected Galleria cadavers in the soil.…”
