The brown bug (Scaptocoris castanea, Perty 1830) is an insect of underground habits, which continuously suctions the juice through the roots leads the plants to emaciate, dry and die. It has not yet been described as pest in cultivated pastures in Brazil. Its occurrence has been observed in cultivated pastures of Cynodon dactylon cv. Coast cross and Brachiaria decumbens cv Brasilik and IPEAN in red-yellow podzolic soil originally covered by savannah vegetation, in Botucatu County, state of São Paulo.

Starches and modified starch derivations are used as carriers in the spray drying processing where apparent density is an important characteristic and should be controlled in dehydrated products for pharmaceutical use. In Brazil, the commercial starches are made from corn and cassava, but there are others with potential for extraction. The canna and taro starches were selected because they represent the extremes of granule size and thus allow the effect of this size on the apparent density of spray dried products to be tested. For comparison, commercial cassava and corn starches which are used in spray-drying and have granules of intermediate size, were also tested. The spray-drying process was carried out with a LabPlant SD 04 Spray Dryer, operating at a pressure of 6 lb/in2, air of 7,6 mL/minute, and 1 cm atomizing nozzle. The air inlet temperature was set at 200°C this model does not allow regulating outlet temperature. The spray-dryer products had boldo leaf extract as base, using the four starches as carrier. The dry product was evaluated for humidity, water activity (Aw), granulometry and apparent density. The results showed that the size of the particles, which was a consequence of the size of the starch granules, influenced the apparent density of the spray dried products, which as higher (694, 27 g/mL) for the canna starch and lower (456, 13 g/mL) for taro starch. Corn and cassava starches showed very close and intermediate values, 521,51 and 58,48 g/mL, which also represent the standard range of starch granule size.
