Climate changes, such as temperature rise, prolonged drought and heavy rainfall, impair human activities, especially the food production sector. Rainfall is one of the most important natural, life-sustaining factors on the planet and it is essential in agriculture, not only to water plants, but also in regulating pest organisms in crops through mechanical control. The mites Brevipalpus phoenicis (Geijskes, 1939) and Oligonychus ilicis (McGregor, 1917) (Acari: Tenuipalpidae, Tetranychidae) are important coffee pests influenced by the rainfall regime. The aim of this work was to study the distribution of coffee predatory (Phytoseiidae family) and phytophagous (B. phoenicis and O. ilicis) mites in function of rainfall, between June/2006 and June/2008, in organic and conventional coffee cultivation systems. The experiments were conducted at Cachoeira (organic coffee production) and Taquaril (conventional system) farms, located in the municipality of Santo Antonio do Amparo, Minas Gerais state, in Brazil. Leaves were removed monthly from the middle part of coffee plants from both systems. It was concluded that rainfall influences the populations of pest and predatory mites in the different coffee production systems, but this effect was less intense in the organic coffee. |

Yerba mate (Ilex paraguariensis) traditionally grown in South America. Its extract contains bioactive compounds which are associated with pharmacological activities. Freeze-concentration (cryoconcentration) process allows the removal of water preserving the bioactive compounds in extracts. Furthermore, yerba mate extract incorporation into starches is promising for food and pharmaceutical uses. This process can be evaluated using simultaneous Thermogravimetry and differential thermal analysis (TG?DTA). The aim of this study was to obtain corn starch incorporated with freeze-concentrated yerba mate extract. The evaluation of freeze-concentration was carried by extracts analyses of density, total dry matter and ash. The evaluation of yerba mate extract incorporation into corn starch was performed using simultaneous TG?DTA system. Density results revealed extracts different composition and dry matter indicated that compounds were concentrated at 0.576% ratio after freeze-concentration stage. Nevertheless, incorporated starches showed exothermic peaks in DTA curves at temperatures between 287 and 514 °C, which increased in intensity in agreement with freeze-concentration stages advance. Thus, yerba mate oxygenated compounds were incorporated into starches. Nutraceutical products can be obtained using the incorporation of yerba mate extract into starches; however, further studies are necessary to extend these applications. |
