Changes in the nutritional composition of maize flour due to Tribolium castaneum infestation and application of carbon dioxide to manage this pest

Phosphine (PH3) is widely used as a fumigant for the control of stored product pests. Indiscriminate use of PH3 leads to the development of resistant strains. Thus, an experiment was conducted in a laboratory scale fumigation chamber to determine the synergistic effect of carbon dioxide (CO2) and PH3 on the mortality of Tribolium castaneum during fumigation of paddy. PH3 gas generation varies depending upon grain moisture content and dosage of PH3 used for fumigation treatment. Thus, the maximum PH3 concentration with respect to saturation time was achieved when paddy were treated with 98% CO2 + 3 ppmPH3 at 17% moisture content, leading to a quick mortality of different life stages of T. castaneum with minimum LT50 and LT99 value. Among the different stages of T. castaneum, pupal stage was more resistant to all the treatments compared to larva and adult stages. PH3 residues in all the treatments were below the recommended level and it can be considered as safe for consumption.

Gas Pressures

One of the new ways of warehouse pest control is the carbon dioxide treatment, which had no residues on the target products. In the present research, at first, CO2 gas was applied to control two important pest species infesting dried apricots. Dry apricots infested with adults of Tribolium castaneum (Herbst) or Rhyzopertha dominica (F.) were exposed to CO2 gas pressures correspond to 9.1, 16.7, 23.1, 28.6, and 33.4 mol% for 24 h. The results showed higher mortality rates with increasing the gas pressures in all the experiments. The minimum and maximum losses of the pests were determined at concentrations of 9.1 and 33.4 mol%, respectively. Evaluation of CO2 gas effects on the quality characteristics of dried apricots showed no impacts on the color, brittleness, hardness, sweetness, sourness, and general acceptance of products. CO2 gas treatments at the concentration of 33.4 mol% showed no significant influences on the chemical features of dried apricots, including pH, acidity, Brix, humidity percentage, reducing sugar, and total sugar. It was concluded that CO2 gas had the potential to control T. castaneum and R. dominica in warehouses of dried apricots, without any significant impacts on product qualities.
