A range of dosages of methyl bromide used according to different chamber and fru:. I+ temperatures, preceded, unaccompanied or followed by cold treatment was found effective in disinfesting apples of the light-brown apple moth, Epiphyas postvittana (Walker), in Tasmania, 1972-1 974. Fumigations were in 1.1 m3 and 14.3 m3 chambers, for 2 or 2+hours, loaded to 40 or 80 per cent of their capacities, and cold storage was for 21 days at 0�C. The disinfestation treatments were tested on apples artificially infested with neonate and fourth instar larvae and on a field line of naturally infested fruit; the onset of fumigation effects on fourth instar larvae in artificial medium was also determined.

AbstractRed Delicious and Winesap apples infested with San Jose scale were placed into either regular (CS) or controlled-atmosphere (CA) cold storage, either with or without prior fumigation with methyl bromide. Fumigation with a dose of 32 g/m3 killed all infesting stages of the scale on Red Delicious apples in CS after 31 days and in CA after 137 days. Complete scale mortality on Winesap apples occurred after 167 days in CA and in CS if previously fumigated.

Efficient strategies are required in sweet cherry fruits to control the spotted wing drosophila (SWD), Drosophila suzukii, due to its adverse economic effect on farmers. Cold storage (CS) and storage with elevated carbon dioxide (CO2) are environmentally safe approaches for the pest control of stored fresh fruit. These strategies are effective in controlling a wide variety of insect species, without allowing toxic compounds to accumulate. The purpose of this study was to assess the effectiveness of a post-harvest application of CO2 treatment at 50%, cold treatment at 4 °C (CT), and a combination of both (CO2-CT) in controlling the early stages of SWD within four cultivars of freshly harvested cherry fruit, namely “Burlat-Bigarreau”, “Giorgia”, “Ferrovia”, and “Lapins”. In addition, an evaluation of the quality attributes of the cherries (skin firmness, berry firmness, strong soluble material, and titratable acidity) was carried out at harvest and after 10 and 20 days of storage. All treatments significantly reduced the rate of emergence of SWD when compared to the control (untreated cherry at 24 °C), and 100% SWD mortality was obtained in Burlat-Bigarreau (CO2-CT). In addition, over the entire storage time, the quality parameters were preserved in the samples stored at 4 °C and in the samples with combined treatments in comparison with the control.

Peach is a climacteric highly-perishable fruit whose post-harvest preservation relies largely on cold storage. The combination of the last with other technologies allows to extend the shelf life of this product. One alternative is the utilization of salicylic acid, a natural compound involved in many physiological phenomena such as resistance against diseases and ripening. Considering these facts, the objective of the present work was to evaluate the effect of pre-harvest application of salicylic acid solutions on the quality of ‘Chimarrita’ peaches during post-harvest cold storage. The experiment was conducted at the Federal University of Pelotas/RS, in the campus of Capão do Leão/RS - Brazil. The application of salicylic acid solutions was performed by direct pulverization on the fruits, 30 days prior to harvest. The concentrations were: 0,0 (control); 1,0; 1,5; and 2,0 mM. After harvest, the fruits were stored in a cold chamber at 1,0 ± 0,5°C and 85-90% RH, for 30 days. The analyses were performed at the following cold storage periods (plus 2 days at room temperature of 20°C to all treatments, in order to simulate commercialization conditions): 10 (+2) days; 20 (+2) days; e 30 (+2) days. The variables evaluated were: mass loss (%); flesh firmness (N); DA index; color (L, a*, b* and hue angle); wooliness incidence (%); rot incidence (%); total soluble solids (°Brix); pH; titrable acidity (% of organic acids); and ratio. The salicylic acid doses and/or the cold storage periods had significant effects on all the evaluated parameters. For most of the parameters analyzed, the intermediate dosis of 1mM (and also 1,5mM) of salicilic acid showed the most promising results. Therefore, the application of salicylic acid solutions 30 days prior to harvest is a technique which can be combined to cold storage in order to shift the quality and the shelf-life of ‘Chimarrita’ peaches.

Inorganic bromide residues were evaluated from fumigation schedules available in Australia for use against Queensland fruit fly, Dacus tryoni (Froggatt) and light brown apple moth, Epiphyas postvittana (Walker) in fruit and vegetables. Capsicums were fumigated for two hours at 20�C with 22 g m-3 ethylene dibromide (EDB). Bromide residues (40-45 �g g-1) were in excess of the maximum residue limit of 10 �g g-1 of the United States Food and Drug Administration (U.S.F.D.A.) and the current 20 �g g-1 recommendation of the Australian National Health and Medical Research Council (N.H.M.R.C.). Bananas were fumigated with dosages of 10, 12 and 14 g m-3 EDB for two hours at 20�C. Bromide residues increased with increasing dosages, and ranged from 11.7 to 15.6 �g g-1. Residues were within the recommended 20 �g g-1 limit of the N.H.M.R.C., but exceeded the 10 �g g-1 limit of the U.S.F.D.A. Cherries were fumigated for two hours at 15�C with 24 and 48 g m-3 methyl bromide (MB). Bromide residues (up to 8 �g g-1) were well within the 20 �g g-1 N.H.M.R.C. and U.S.F.D.A. limits. Apples were fumigated for two hours at 15�C with 24 g MB m-3 and at 7�C with 32 g MB m-3. Residues approximated or were less than the 5 �g g-1 limit of the U.S.F.D.A. and considerably lower than the 20 �g g-1 N.H.M.R.C. recommendation.

Over 90% of global yam production is from West Africa where it provides food and income for above 300 million smallholders’ farmers. However, the major challenge of yam is 10–40% post-harvest losses due to the lack of appropriate storage facilities. This paper assesses a biogas-driven cogeneration system, which could supply electricity and cold storage for ‘yam bank’ within a rural community. Considering 200 households’ Nigerian village as a case study, crop residues are used as anaerobic digestion feedstock to produce biogas, which is subsequently used to power an internal combustion engine. Result shows that the system could store 3.6 tonnes of yam tubers each year and provide enough electricity for domestic and commercial activities. At the current electricity tariff of USD0.013·kWh−1 for rural areas, the system is unable to payback during its life span. The proposed USD0.42·kWh−1 by Nigerian Rural Electrification Agency seems good with less than 3 years discounted payback period but brings about extra burden on poor rural households. Based on the income from cold storage, electricity tariff of USD0.105·kWh−1 with an interest rate of 4% is suggested to be reasonable which results in 6.84 years discounted payback period especially considering non-monetary benefits of renewable energy system.
