| The brown stink bug, Euschistus servus (Say), is abundant throughout most of eastern North America and is commonly found feeding on soybean, mullein, beans, tomatoes, peas, cotton, wheat, corn, tobacco and peach. Color change in E. servus from green to reddish-brown was shown to be an indicator of reproductive diapause. Reddish-brown insects lived longer than green individuals, females laid no eggs, and males did not produce pheromone. The high mortality registered for the green colony of E. servus adults was associated with the physiological cost associated with reproduction. The main pheromone component of this species is methyl 2E,4Z-decadienoate, in agreement with previous work. The first generation of this species develops on noncrop hosts and the... |

| Some individuals of the species Arenaeus cribrarius (Lamarck, 1818) bear a characteristic pink abdomen, which is notably different from the usual white coloration. The incidence of this chromatic alteration was determined for a single population and its relation with other individual variables were examined. The individuals were monthly collected from May, 1991 to April, 1993, in Ubatuba, São Paulo, with the aid of a shrimp fishery boat provided with double-rig trawling nets. All specimens were sexed, measured (CW = carapace width), distributed in 10-mm size classes and classified according to growth phase (juvenile and adult), molting condition and development stage of gonads. The occurrence of pink-colored morphs was also recorded. From a total of 2,096... |

| ABSTRACT Yerba mate shows social and economic importance for the Southern Latin American countries due to its easy production and large market range. However, there is a problem to harvest the yerba mate at the correct period and to store it until processing and marketing. Thus, the aim of this paper was to evaluate the interaction among the storage in controlled atmosphere, effect of cultivation form and shelf life period on yerba mate quality after long-term controlled atmosphere storage. The experiment was conducted in a factorial arrangement (3 controlled atmosphere conditions × 2 cultivation forms × 4 weeks of shelf life). Native yerba mate, stored under controlled atmosphere, showed higher chlorophyll concentration as compared to the cultivated one.... |

| The purpose of this study was to evaluate the effect of ozone on the quality of peanut grains and crude oil extracted from these grains. Peanut samples of 1 kg were used, with a moisture content of 8.0% w.b. and stored in 3 L glass recipients. The ozonization process utilized ozone gas concentrations of 13 and 21 mg L-1, temperature of 25 °C, exposure periods of 0, 24, 48, 72 and 96 h, and a flow rate of 1.0 L min-1. Evaluation of peanut quality consisted of analysis for moisture content, electrical conductivity, lipid concentration and peanut color. The qualitative parameters of the crude oil evaluated were free fatty acids, peroxide index and iodine index. In general there was no alteration in peanut quality due to ozone, except for the coloration of the... |

| Abstract Passiflora cincinnata Mast. or Caatinga passion fruit is widely cultivated in the northeastern semi-arid regions of Goiás, Minas Gerais, and Bahia. The system of cultivation and field management of the Passiflora species affects the physicochemical quality of its fruits. In this study, we evaluated the chemical and physico-chemical characteristics of the fruits of 2 progenies (CPEF2220 and CBAF2334) of P. cincinnata species using the vertical and horizontal trellis system. Fruits were collected from the plants at their physiological maturation stage and tested for the fruit skin color and texture and the pH, total soluble solids, titratable acidity, pulp acidity ratio, and the contents of flavonoids, anthocyanins, and polyphenols in the seedless... |
