Successful biological control of the whitefly Bemisia tabaci involves the mass rearing of biocontrol agents in large numbers for field release. Cold storage of the biocontrol agents is often necessary to provide a sufficient number of biocontrol agents during an eventual pest outbreak. In this study, the fitness of two whitefly parasitoids Encarsia sophia Girault and Dodd (Hymenoptera: Aphelinidae) and Eretmocerus hayati Zolnerowich and Rose (Hymenoptera: Aphelinidae) was evaluated under fluctuating cold storage temperatures. The emergence rate of old pupae of either species was not affected when stored at 12, 10, 8 and 6 °C for 1 week. Cold storage had no effect on the longevity of the emerging adult En. sophia except young pupae stored at 4 °C, while Er. hayati was negatively affected after 2 weeks of storage time at all temperatures. Parasitism by adults emerging from older pupae stored at 12 °C for 1 week was equivalent to the control. Combined with the results for the emergence time, we suggest that the old pupal stage of En. sophia and Er. hayati could be stored at 12 and 10 °C, respectively (transferred every 22 h to 26 ± 1 °C for 2 h), for 1 week, with no or little adverse effect.

Tujuan dari penelitian ini adalah untuk menentukan waktu perlakuan optimal dan suhu penyimpanan dingin untuk mutu kubis bunga. Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri dari dua faktor, faktor pertama adalah suhu yang digunakan dan faktor kedua adalah waktu selama show case. Faktor pertama terdiri dari dua level, yaitu (P1): show case temperature 8oC, dan (P2): show case temperature 15oC dan tambah kontrol (P0). Faktor kedua terdiri dari empat level, yaitu (A0): penyimpanan selama 0 jam, (A1): penyimpanan selama 12 jam, (A2): penyimpanan selama 16 jam, (A3): penyimpanan selama 20 jam dan diulang untuk 3 kali ulangan. Kubis bunga sebagai kontrol disimpan pada suhu kamar (28 ± 1 ?). Parameter kualitas yang diamati dalam penelitian ini termasuk penurunan berat badan, tingkat konsumsi O2, warna (warna berbeda), uji organoleptik termasuk umur simpan dan tingkat kerusakan. Hasil penelitian menunjukkan parameter penurunan susut bobot, laju konsumsi O2, warna, umur simpan, tingkat kerusakan pada suhu perlakuan suhu terbaik adalah suhu 8 ? dan waktu penyimpanan 20 jam (P1A3).Kata kunci: kembang kol, waktu penyimpanan, suhu penyimpanan dingin   The purpose of this study was to determine the optimal treatment time and cold storage temperature for the quality of cabbage flowers. This study uses a completely randomized design (CRD) consisting of two factors, the first factor is the temperature used and the second factor is the time during the showcase. The first factor consists of two levels, namely (P1): showcase temperature of 8oC, and (P2): showcase temperature of 15oC and added a control (P0). The second factor consists of four levels, namely (A0): storage for 0 hours, (A1): storage for 12 hours, (A2): storage for 16 hours, (A3): storage for 20 hours and repeated for 3 replications. Flower cabbage as control was stored at room temperature (28 ± 1 ?). The quality parameters observed in this study included weight loss, O2 consumption rate, color (color different), organoleptic tests including shelf life and damage level. The results showed the parameters of weight loss, O2 consumption rate, color, shelf life, damage rate at the best temperature of 8 ? and storage time of 20 hours (P1A3).

<p>Fruit nutrient elements content during harvest could considerably effect on postharvest life of apples. In this study, apple fruits cultivar Red Delicious were harvested at the commercial maturity stage at 20 commercial orchards. Fruits were divided into three groups according to peel color; dark red, medium and light red. The mineral elements nutrient content such as nitrogen, phosphorus, potassium, calcium and magnesium and their ratios were measured in the harvested fruits. Thereafter, fruits were places in the cold storage at 0 °C and relative humidity of 90% for 4 months. The characteristics such as fruits weight loss, firmness, TSS, dry matter, total anthocyanin content, antioxidant activity, respiration rate and ethylene production were measured at the end of storage. The results showed a positive significant correlation between fruit firmness at the end of storage time with N+K:Ca, K+Mg:Ca, K:Ca and Mg:Ca ratios. Furthermore, a negative significant correlation was found between total anthocyanin with Nitrogen content, Mg:Ca and N:Ca ratios. The results also showed a positive significant correlation between fruit respiration rate and Nitrogen, N+K:Ca and N:Ca ratios. The analysis of regression based on mean values of three red apple groups showed a significant negative correlation between total anthocyanin with fruit ethylene production at the storage time and Mg:Ca ratio. The relationship between these two variables and Anthocyanin was expressed by the equation of regression: Anthocyanin = 100.22–1.651 Ethylene–43.963 Mg:Ca. Overall, the results confirm that measurement of fruit mineral composition during harvest time could be a strategy for predicting postharvest behaviors of apple fruits at the cold storage. Also the results showed that a relationship between mineral nutrient composition and the characteristics such as firmness, anthocyanin, respiratory rate in apple fruits.</p>

Stem Quality

Rosa sp. is the leading cut flower commercialized in Brazil and in the world; and to maintain stem quality it should be stored at 1 °C, however, there are still doubts about the storage of roses, especially whether the stems should be cold stored in water before marketing. In order to assess the feasibility of wet and dry storage, rose stems, ‘Avalanche’ were stored for 28 days in both conditions at 1 ± 2 °C / 95% RH. Weekly stems batches were transferred to 25 °C / 70% RH and kept in vessels containing tap water for postharvest assessment. It was observed that the decrease in the quality of the roses was inversely proportional to the storage time in both treatments. Although wet storage can occur for up to 21 days, when you need to store roses for a week or two, cold storage in dry condition is advised since it is more economical and viable for the producer.

ABSTRACT The objective of this work was to evaluate the tolerance of fruits of different banana cultivars to low temperature storages. Fruits of the cultivars Nanicão (AAA), Prata (AAB), Vitória (AAAB), Maçã (AAB) and Caipira (AAA) were used. Clusters of three fruits were kept in cold storage for 7, 14 and 21 days, with average temperature of 10.53±0.37°C and relative humidity of 85%. Subsequently, the clusters were transferred to temperatures of 22±0.39°C and evaluated for 16 days. The fruits of all cultivars remained green after 21 days of storage at 10.53±0.37°C. Fruits of the cultivar Nanicão did not completely ripened after transferred to the 22°C storage, when stored for 7 days at low temperature. These fruits were firmer, with green peel and low soluble solids and titratable acidity. The fruits of all cultivars complete the ripening when transferred to room temperature after 21 days of cold storage. Chilling injuries increased with cold storage time in all cultivars. The cultivars Nanicão, Caipira and Maçã had more symptoms of chilling injury, while Prata and Vitória were more tolerant to the cold storage (10.53°C) for up to 21 days, showing normal ripening after transferred to the 22±0.39°C storage.

Abstract Field survival of longleaf, shortleaf, slash, and loblolly pine seedlings that had benomyl incorporated into the packing medium was markedly improved over that of clay-slurry controls. The more difficult to store seedlings of longleaf and shortleaf pine had greater magnitudes of response than more easily stored loblolly and slash pines. The decrease in seedling survival with storage time is related to a rapid increase in pathogenic microorganisms in cold storage. Although Benlate® ¹ 50WP is now registered for this use, the most effective fungicide dosage rates for routine use with different southern pine species must still be determined. South. J. Appl. For. 12(4):281-285.
