“…Therefore ozone can safely be used in the food processing industry (Palou et al, 2002;Forney et al, 2007;Wei et al, 2007). Some studies have been published on its efficacy as a fumigant against pests of stored products (Erdman, 1980;Kells et al, 2001;Sousa et al, 2008). The efficacy of ozone against T. castaneum and T. confusum has been investigated by mortality of larvae (Erdman, 1980).…”

ABSTRACT:Multiple microwave power (MP) has been applied against Ephestia cautella (Walker) at various exposure times. Five seconds exposure time at various MP up to 60% had no effect on insect mortality, by increasing the MP up to 100%, the mortality reached 20% for larvae and 33% for adults. When exposure time was increased to 15 seconds with different MP, mortality reached 100% and 80% at 60% power for adults and larvae, respectively. Eggs of E. cautella were exposed to various MP at different time; the hatchability reached 0.0 % after 10 and 15 seconds at 100% MP. Data showed microwave had no effect on soluble proteins isolated from dates treated by microwave at various time up to 15 seconds, and had no effect on protein pattern on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Ozonation with 2.0 ppm ozone generated with various time 4, 8 and 12 hours, gave 28%, 73%, and 83% mortality against adults, while it gave 10%, 20% and 27% mortality against larvae. Ozone exhibited less effect against pupae and eggs hatchability. The possibility of using microwave and ozone in integrated management program against stored product pests is discussed.

-Large amounts of dates are produced and consumed around the world each year. Apomyelois ceratoniae causes main losses during storage and export of date fruit. Fumigation is the most widely used treatment to prevent postharvest losses. However, this treatment negatively affects the biological value of dates, environmental and economic parameters of production. Widespread fumigation agent methyl bromide is toxic to a human body and contributes to the destruction of the ozone layer. The aim of the current work was to find a new method based on the use of low temperature refrigeration to reduce the pest and insect infestation preserving the nutritive value of dates during cold storage at the same time. A. ceratoniae mortality under different temperatures and dates respiration rate, sugar, organic acids, pectic substances content and sensorial characteristics were studied. The results indicate that at −18 °С the A. ceratonie larva dies within 2 h, the eggs and larvaewithin 24 h respectively. Thus, it is clearly shown that there is no need in using chemicals or irradiation to prevent dates pests. Physicochemical and organoleptic proprieties of dates were satisfactory during 360 d at −18 °С and during 180 d at +4 °С. The low temperature refrigeration and storage at −18 °С is recommended for dates to prevent pests and quality losses. It is apparently advantageous for environment and climate if compared with other anti-pest treatment variants.

“…Recently, the feasibility of using ozone to manage stored product pests has received increased attention. Several studies have been carried out on the efficacy of gaseous ozone against stored product insect pests (Erdman 1980;Mason et al 1997;Kells et al 2001;Sousa et al 2008;Bonjour et al 2011;Hansen et al 2012). Ozone also has the potential for controlling insect strains that are resistant against phosphine (Zhangui et al 2003;Sousa et al 2008).…”

Abstract:In Iran, the Indian meal moth, Plodia interpunctella (Hübner), is one of the most important pests of such stored products as date fruits and pistachio nuts. Ozone was applied as a gas at four concentrations (0, 2, 3, and 5 ppm) for four different periods (30, 60, 90, and 120 min) on the immature stages of P. interpunctella. The results indicated that by increasing the concentration and exposure time, the rate of mortality increased for all tested stages. This study showed that 12-day-old larvae were more susceptible than other stages when exposed to 5 ppm ozone for 120 min. The next in order of susceptibility were pupae, then 5-day-old larvae, and 17-dayold larvae had the highest sensitivity to ozonation. At the highest concentration of ozone, for the longest time, the least mortality rate was recorded for one-day-old eggs. According to the results, a reduction in the population density of P. interpunctella in laboratory experiments is promising. However, validation studies will be necessary to fully determine the potential of ozone as a replacement for the current post harvest chemical control of P. interpunctella on either pistachio nuts or date fruits.
