Sampling techniques currently used to determine control measures for the Coffee Berry-borer (CBB) are time-consuming and allow the grower only a small window of opportunity to select other options. Experiments were conducted in four coffee fields between 2005 and 2007 using IAPAR® traps that were baited with ethanol and methanol (1 : 3 ratio) and benzaldehyde at 1% volume, to test for a correlation between the number of captured adults and infestation levels of CBB, and to determine the action threshold level. For this study, a density 20 traps/ha was used in each experimental area. The number of CBBs captured and infestation level on coffee berries were recorded every 2 weeks. Significant correlation was observed between the trap capture and the infestation level of the CBB in the field. This correlation can enable us to determine action thresholds using traps as sampling methods. Trap catch was very low in all four fields during fruit maturation between March and July, and it increased sharply in August when the CBB emerged from the dry berries that remained on the plants or on the ground.

However, for pot cultivation, there are few commercial cultivars available, since most plants of Capsicum are relatively large and were selected for field cultivation to produce fruits for fresh consumption or for industrial processing (^{Finger et al., 2012}).

Leafy vegetables are highly perishable and highly susceptible to water loss, which can be intensified by inadequate handling of temperature and air humidity in storage and marketing places, with consequent reduction in shelf life and increase in the final cost of the product to consumers (^{Álvares et al., 2007}). In general water loss through transpiration determines, most of the times, quantitative and qualitative losses of vegetables (^{Finger & Vieira, 1997; Finger et al., 2008}).

Plant exposure to ethylene can cause leaf, flowers and fruits abscission (^{Sundaresan et al., 2015}; ^{Lima et al., 2017}). Ethylene accumulates in the air spaces between receptacle and the fruit, where it can coordinate the abscission rate in multiple zones through the combined activity of different degrading enzymes, several of which are regulated by this hormone (^{Agarwal et al., 2012}). However, the ethylene concentration required to cause these effects depend on exposure time, temperature, development stage, and species or variety sensitivity (^{Xin et al., 2019}).

ISHS XI International Controlled and Modified Atmosphere Research Conference ACTION OF POTASSIUM PERMANGANATE ON THE SHELF-LIFE OF CUCUMIS ANGURIA FRUIT

1-MCP has been effectively used as an antagonist of ethylene deleterious actions in flowers and ornamental plants. The objective was to evaluate the efficiency of 1-MCP (0.0, 0.5, 1.0 and 1.5 g m(-3)) in maintaining post-production quality of exogenous ethylene sensitive ornamental pepper. Two commercial varieties were evaluated: Pimenta Colorida and Pimentio Ornamental, both Capsicum annuum. The pre-treatment with 1-MCP, regardless of the applied concentration, was effective in blocking the ethylene action reducing the leaves abscission, flowers and fruits of both genotypes by 100%. Plants pretreated with 1-MCP had postproduction life increased by eight and nine days for Pimenta Colorida and Pimentao Ornamental, respectively. The 1-MCP application at the concentration of 1.0 g m(-3) is efficient in maintaining ornamental quality and prolonging the shelf life of Pimenta Colorida and Pimentao Ornamental.
