In the insects’ habitats, they tend to become exposed to multiple pathogens, from different parasites that may regulate wild insect populations but may also have a wide impact on farmed species (Jansson et al., 2015). The problematic effects of these diseases are not well known with regard to insect farming for food, however Weismann et al. (2012) found that the cricket Acheta domesticus is known to be affected by a densovirus and in the USA, the pet food industry was negatively affected by epizootic densovirus outbreaks. For this reason the FAO (2013) recommends maintaining a parent line if insect rearing on an industrial scale is practiced, regardless of the insect species, in case of any disease outbreak or bio-security risks
