“…Our samples with nematodes were obtained from, clay (75%) and sandy (25%) soils, indicating the mobility and survival of EPNs in soils rich in sand, but S. rarum occurred in clay (FCA 09 and FCA 10) and sandy (FCA, 11, 12, 13 and 14) soils. Many EPNs positive samples (89.65%) were obtained in acid soils in Nepal51. Six EPNs were found in soils with PH < 4, which is uncommon, but this has also been reported in Belgium52.…”

Entomopathogenic nematodes (EPNs) (Steinernematidae and Heterorhabditidae) can control pests due to the mutualistic association with bacteria that kill the host by septicemia and make the environment favorable for EPNs development and reproduction. The diversity of EPNs in Brazilian soils requires further study. The identification of EPNs, adapted to environmental and climatic conditions of cultivated areas is important for sustainable pest suppression in integrated management programs in agricultural areas of Brazil. The objective was to identify EPNs isolated from agricultural soils with annual, fruit and forest crops in Brazil. Soil samples were collected and stored in 250 ml glass vials. The nematodes were isolated from these samples with live bait traps ([Galleria mellonella L. (Lepidoptera: Pyralidae) larvae]. Infective juveniles were collected with White traps and identified by DNA barcoding procedures by sequencing the D2/D3 expansion of the 28S rDNA region by PCR. EPNs identified in agricultural areas in Brazil were Heterorhabditis amazonensis, Metarhabditis rainai, Oscheios tipulae and Steinernema rarum. These species should be considered pest biocontrol agents in Brazilian agricultural areas.

“…However, EPNs have been isolated from a broad range of locations from the sub-arctic to the tropics (Glazer, 2002;Hominick et al, 1996;Khatri-Chhetri, Waeyenberge, Manandhar, & Moens, 2010;Poinar, 1990), and different EPN species and populations exhibit various temperature tolerances, which can be modified by selection (Grewal, Gaugler, & Shupe, 1996;Grewal, Gaugler, & Wang, 1996;Grewal, Selvan, & Gaugler, 1994;Jagdale & Gordon, 1998;Mason & Hominick, 1995;Westerman, 1998). Heterorhabditid isolates from Israel (Glazer et al, 1991), Egypt (Shamseldean & Abd-Elgawad, 1994) and Sri Lanka (Amarasinghe, Hominick, Briscoe, & Reid, 1994) have been shown to be especially heat tolerant.…”
