“…Several other studies have also advocated for the efficiency of MA applications against arthropod pests of dried fruits and as potential alternatives to methyl bromide (Soderstrom et al, 1984;Soderstrom et al, 1986;Navarro et al, 1993;Donahaye et al, 1994;Navarro et al, 1997;Donahaye et al, 1998;Navarro et al, 1998;Navarro et al, 2000). Recently, Ahmed et al (2014) reported that all eggs and larval stages of angoumois grain moth, Sitotroga cerealella (Olivier) were killed within 3 d and all pupae within 4 d when treated with 75% CO2 at 34°C. Our studies indicated promising results for controlling the almond moth, with 100% CO2 for 24 hours yielding 100% larval mortality.…”

The efficacy of CO2 and N2 gases alone or in a mixture was tested against eggs, larvae, and pupae of the almond moth, Cadra cautella, a major date fruit pest, under temperature regimes of 5°C and 25°C. Our results indicated that exposing different stages to higher concentrations of CO2 significantly affected egg hatchability, larval mortality, and pupal mortality as compared to 100% N2 gas, at both temperature regimes. Application of CO2 at lower doses (below 50%) did not give 100% mortality of any developmental stage even at longer exposure timings. However, treatments at higher doses (75 and 100% CO2) were effective at 24 h and longer treatment duration. The application of 100% N2 did not effectively control C. cautella. Of all the stages, the larvae of C. cautella were most susceptible to the gases. Our results indicated that temperature has a significant effect on the efficacy of gases or their combinations tested after an exposure of 48 h and longer. Based on current findings, we conclude that CO2 gas is a good candidate for successful control of C. cautella immature stages under storage conditions and can be a potential alternative to highly toxic methyl bromide.

BACKGROUND Cadra (=Ephestia) cautella (Walker) is a serious cosmopolitan pest that can feed on a wide variety of stored foods. It is controlled mainly by fumigation with phosphine, to which strong resistance has been documented in major stored‐product insects in many countries. The need for reliable, user‐ and environmentally friendly alternatives is therefore high on the agenda to avoid the development of potential resistance and to reduce human exposure to toxic insecticides. Two modified atmospheres (MAs) composed of high carbon dioxide (CO2) and low oxygen (O2) (90% and 96% CO2 in air) were studied at the laboratory at 20 °C and 65 ± 3% relative humidity (RH) against C. cautella. RESULTS Eggs (1, 2, and 3 days old), young and mature larvae (10 and 20 days old), pupae (1, 2 and 3 days old) and adults (1 day old) were exposed to two MAs consisting of high CO2 and low O2 for the range of 2 to 104 h. Eggs, old larvae, and pupae were found to be the most tolerant. Adults were rather easily killed and young larvae were the most susceptible. Lethal exposure time (LT99) values were between 11.74 h and 128.97 h. CONCLUSION Modified atmospheres consisting of high CO2 and low O2 offer an affordable combination to control C. cautella effectively. From the perspective of economics and efficacy, 90% CO2 might be the concentration of choice. © 2019 Society of Chemical Industry

“…Hashem, Ahmed, El‐Mohandes, and Gharib (2012) reported the effect of modified atmospheres enriched with CO 2 against saw‐toothed grain beetle, Oryzaephilus surinamensis and found that the eggs and pupae were more tolerant and required about 4 days of treatment for their complete removal at CO 2 concentrations higher up to 75%. A study on the comparative effects of different altered atmospheric conditions on immature stages of S. cerealella was conducted by Ahmed, Hashem, and El‐Sherif (2014) and they observed that the order of sensitivity decreases from eggs, pupae, and then to larvae. A combination of higher temperatures with an increase in CO 2 composition was more effective in suppressing adult emergence from immature stages.…”

Management of stored product insects is a major concern and widely researched topic in the food and grain processing and storage industry. In the scenario of estimated utilization of produces exceeding the production, postharvest losses should be properly controlled to feed the growing population. The prevailing disinfestation techniques are forced to meet regulatory standards and market demands. The resistance developed by insects, environmental concerns, and occupational hazards lead to the vanishing of many chemicals used in insect and pest management programs. Some of the major disinfestation techniques such as the use of chemical fumigants, ozone, irradiation, dielectric heating, extreme temperature treatments, and bio rational approaches are discussed, particularly on the storage of cereal grains and its products, as they contribute to a significant proportion of food consumed worldwide. Newer techniques such as nonthermal plasma and metabolic stress disinfestation and decontamination for stored pest control are developed and evaluated in different parts of the world. The knowledge about the mode of action of these disinfestation techniques is important to avoid the cross-resistance and multiple resistance developed by insects with frequently used techniques. Various alternatives to conventional fumigants are discussed in this review as there is a growing demand for toxic-free, environment-friendly, and, at the same time, efficient techniques.
