“…The model involves the following parameters: (a) time required for the IJ to reach the adult stage ( λ ), (b) EPN multiplication factor, ( C / C 0 ) max , where C 0 is the initial total IJ concentration, and (c) maximum population growth rate ( m max = { d ( C / C 0 )/ dt } max ). This model has been used for the data analysis in in vitro production studies of S. feltiae (Mexican; Chavarría‐Hernández & De la Torre, 2001), S. carpocapsae (Mexican; Chavarría‐Hernández et al, 2006; Chavarría‐Hernández, Islas‐López, Maciel‐Vergara, Gayosso‐Canales, & Rodríguez‐Hernández, 2008; Chavarría‐Hernández, Islas‐López, Maciel‐Vergara, Pastrana, & Rodríguez‐Hernández, 2008), and S. colombiense (Pérez‐Campos et al, 2018), with good results.…”

Monoxenic liquid culture is the most suitable technology for scaling up to industrial production of entomopathogenic nematodes (EPNs); however, the variability of the yield production remains a current problem in the process. The aim of this study was to analyze the parameters and criteria for EPN production in liquid culture based on scientific and technological knowledge from the last two decades. While experimental research has permitted the yield production of Heterorhabditis bacteriophora (362 × 10 3 infective juveniles [IJs]/ml) and Steinernema carpocapsae (252 × 10 3 IJs/ml), simultaneously, theoretical approaches have contributed to the understanding of the culture process, based on biological parameters of the bacterium-nematode complex and hydrodynamic and rheological parameters of the complex gas-liquid-solid system. Under this interdisciplinary research approach, bioprocess and biosystem engineering can contribute to design the various control strategies of the process variables, increase the productivity, and reduce the variability that until now distinguishes the in vitro production of EPNs by the liquid culture.

The development and use of entomopathogens as classical, conservation and augmentative 26 biological control agents have included a number of successes and some setbacks in the past 15 27 years. In this forum paper we present current information on development, use and future 28 directions of insect-specific viruses, bacteria, fungi and nematodes as components of integrated 29 pest management strategies for control of arthropod pests of crops, forests, urban habitats, and 30 insects of medical and veterinary importance. 31Insect pathogenic viruses are a fruitful source of MCAs, particularly for the control of 32 lepidopteran pests. Most research is focused on the baculoviruses, important pathogens of some 33 globally important pests for which control has become difficult due to either pesticide resistance 34 or pressure to reduce pesticide residues. Baculoviruses are accepted as safe, readily mass 35 produced, highly pathogenic and easily formulated and applied control agents. New baculovirus 36 products are appearing in many countries and gaining an increased market share. However, the 37 absence of a practical in vitro mass production system, generally higher production costs, limited 38 post application persistence, slow rate of kill and high host specificity currently contribute to 39 of Bt toxins, has been conducted over the past two decades. The Bt genes used in insect-resistant 54 transgenic crops belong to the Cry and vegetative insecticidal protein families of toxins. Bt has 55 been highly efficacious in pest management of corn and cotton, drastically reducing the amount 56 of broad spectrum chemical insecticides used while being safe for consumers and non-target 57 organisms. Despite successes, the adoption of Bt crops has not been without controversy. 58
