“…For biocontrol purposes, nematodes are typically applied inundatively in high numbers (at least 2.5 10 9 IJs/hectare, Shapiro-Ilan, Han, & Dolinski, 2012). Their fate will depend on a multitude of interacting factors, including soil conditions, crop type and the quality of the applied inoculum.…”

“…Although excellent insect-pest control agents, IJs' persistence and survival in the soil can be affected by abiotic (i. e. humidity, temperature, soil texture and pH) and biotic (i. e. pathogenic bacteria and nematophagous fungi (NFs)) factors [62] . Andaló et al [63] assessed the susceptibility of H. amazonensis IJs to the NFs Arthrobotrys oligospora Fresenius, A. conoides Drechsler and Duddingtonia flagrans (Duddington) Cooke.…”

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.

“…EPNs do not induce genetic resistance in insect pests, and do not contaminate water or soil, unlike chemical residues from pesticides. Moreover, they are easy to handle and do not require specialized application equipment or safety equipment, and they can be applied to the soil as an aqueous solution or using insect cadavers [2] . These nematodes are obligate insect pathogens, but individuals of the third juvenile stage (J3), also called infective juveniles (IJs), are free living, and they search the soil for susceptible hosts.…”

“…Although there are clear differences in behavior between EPN species traditionally classified as ambushers and those classified as cruisers, it is becoming increasingly clear that S. carpocapsae, a so-called ambusher, can find and infect reasonably sedentary hosts at considerable distances from the application point and its behavior could be habitat-dependent, creating some doubt about the established classification [10] . Although excellent insect-pest controllers, IJs' persistence and survival in the soil can be affected by abiotic (i. e. humidity, temperature, soil texture and pH) and biotic (i. e. pathogenic bacteria and nematophagous fungi) factors [2] . Nematophagous fungi (NFs) are an important group of natural enemies of EPNs [11,12,13] .…”

HIGHLIGHTS• Arthrobotrys musiformis AM4 and Arthrobotrys sp. CO7 were the most aggressive tropical fungi tested againstHeterorhabditis indica LPP30.• Water agar medium provided the best conditions to test nematode-fungus interaction with lowest environmental impact among the six media tested.• H. indica LPP30 was more apprehended than S. carpocapsae All by both tropical fungi tested.• In a soil environment, there was a repellent action from Arthrobotrys sp. CO7 against S. carpocapsae All.ABSTRACT: This study settles a step toward to understanding the interaction between nematophagous fungi (NFs) generally found in the soil and entomopathogenic nematodes (EPNs) used in the control of agricultural pests. There are very few studies linking EPNs and their natural enemies around the world and none in Brazil. Therefore, we decided to test differences regarding aggressiveness and susceptibility among the fungi and EPNs found and used in this country. The aim of this work was to study the interactions between the tropical native NFs, Arthrobotrys oligospora AM2, Arthrobotrys musiformis AM4, Arthrobotrys sp. CO7, Arthrobotrys sp. CC7 and the EPNs, Heterorhabditis indica LPP30 (Heterorhabditidae), a native nematode, and Steinernema carpocapsae All (Steinernematidae), a exotic nematode, under laboratory conditions. The interaction was studied in four aspects: 1) NF aggressiveness against EPNs; 2) effect of culture medium on NF aggressiveness to infective juveniles (IJs); 3) EPN susceptibility to NFs; and 4) dispersion of IJs in two types of soil in the presence of NFs. The fungi A. musiformis AM4 and Arthrobotrys sp. CO7 were considered the most aggressive among the tested strains, since they trapped more IJs. Water agar medium provided the best conditions to test nematode-fungus interaction among the six media tested, since the fungi tested produced more trapping structures to apprehend IJs on it. Both fungi were considered very aggressive to EPNs due to their apprehension capacity. Regarding susceptibility, H. indica LPP30 IJs were more susceptible than IJs of S. carpocapsae ALL to both A. musiformis AM4 and Arthrobotrys sp. CO7 in the first 24 h of contact. However, after 48 h, the means of IJs captured by the fungi became statistically equal, except for S. carpocapsae All in Assay 2, which presented the highest mean capture rate. The fungus Arthrobotrys sp. CO7 repelled S. carpocapsae All IJs in sand at 15 cm. The more we learn about biotic factors that interfere in biocontrol, the more effective we can make it. Future studies will focus on the characterization of these interactions in the field under tropical conditions.
