Using Nitrogen for the Control of Stored Product Insects: One Single Application for Multiple Purposes

Abstract

Nitrogen treatment can be used as an alternative method to chemical control. Most of the research on nitrogen treatment mainly investigated the optimum concentration of oxygen level as well as duration as a means of insect control. Other parameters such as temperature and different insect species have been extensively studied and recent research focus on the modelling of nitrogen concentration and the efficacy on commodity. In this paper, we briefly review the major parameters (temperature, oxygen level, relative humidity, exposure time) using nitrogen treatment against stored product insects. Exposure to different oxygen levels or different exposure times can remarkably change pest control mortality. Moreover, different insect species and life stages have differing susceptibility to nitrogen treatment. Finally, these studies are reviewed in this paper to illustrate that nitrogen treatment can be used as a part of an IPM strategy.
