Entomopathogenic nematodes (Steinernema spp. and Heterorhabditis spp.) and the slug-killing nematode Phasmarhabditis hermaphodita have advanced from niche products to key biopesticides within the past 30. years. They can be produced either on their hosts or on artificial solid or liquid medium. All three methods are still used for Steinernema and H...

Combinations of entomopathogenic nematodes Steinernema longicaudum X-7 and Heterorhabditis bacteriophora H06 with chlorantraniliprole, diflubenzuron, and imidacloprid insecticides at different rates for the control of the white grub, Holotrichia oblita Faldermann (Coleoptera: Scarabaeidae), were evaluated both in the laboratory and in peanut fields...

... Nicholas (1962) cultivated Acrobeloides species with some modi cation in Rhabditidae species culture media, and axenic cultivation was successfully performed for A. buetschlii [36]. Considering some critical factors, such as temperature, pH and essential elements for the survival and growth of nematodes, large-scale cultivation of nematodes can be preferred by effectual in vivo techniques based on solid-state culture [37,38]. In the current cultivation experiment, different pH, temperature and nutrient media were standardized for the best growth conditions of A. maximus. ...
... EPNs from genera Steinernema and Heterorhabditis have been investigated the most for their ability to manage pests such as Spodoptera sp. (Negrisoli et al., 2010;Yadav et al., 2017;Khan et al., 2018;Bhat et al., 2017Bhat et al., , 2018Bhat et al., , 2019, Plutella xylostella (Somvanshi et al., 2006;Sunanda et al., 2014), Tuta absoluta (Garcia-del-Pino et al., 2013;Amizadeh et al., 2019;Sabino et al., 2019), Galleria mellonella, Pectinophora gossypiella, Leucinodes arbonalis (Khan et al., 2020), Anomala orientalis, Popillia japonica, Cyclocephala borealis (Liesch et al., 2010), Holotrichia parallela (Guo et al., 2017), Helicoverpa armigera (Kajol et al., 2020;Rana et al., 2020;Bhat et al., 2020bBhat et al., , 2021, Zophobas morio (Navarez et al., 2020) and other destructive insects. EPNs were first discovered in the 1920s and began to gain popularity in the 1950s, with commercialization beginning in the 1980s. ...
