Abstract: Recently Frisvold (2018) have underlined for the case of pesticides productivity that: "in a nutshell: pests matter, statistical specification matters, pest resistance matters, crop quality matters, pest control on neighboring farms matters, and production risk matters". Even though not a single study has addressed all those issues at once, what is more striking is the quasi-absence of any allusion to natural predators. If in integrated pest management schemes (Barzman, et al., 2015), natural predators are used in conjunction with pesticides to fight pests, it appears that the economic literature has overlooked this possibility. We hereby propose in this article a new framework of modelling production technology which not only accounts for pest pressure but also their natural predator. To this aim we follow the original ideal of Frisch (1965) who considered that production process due to their complexities can be described by several relations.
