The establishment of laboratory colonies of ticks is often hampered by their lack of adaptation to alternative hosts. The aim of this study was to artificially feed partially engorged Dermacentor (Anocentor) nitens females through plastic tips, and to identify what are the optimal conditions of application of this technique to get as much as possible close to the natural conditions. The technique of artificial feeding through plastic tips allowed the engorgement of D. nitens ticks to a final weight within the normal range for the species. (C) 2014 Published by Elsevier GmbH.

This article investigates the productivity and production function of thirteen large Brazilian textile and clothing companies before and after the end of the Agreement on Textiles and Clothing (AVT) that abolished import quotas in 2005. For this purpose, we estimate the stochastic production frontier in panel data between 1997 and 2008 and simultaneously an explanatory equation for the (in)efficiency of firms, as proposed by Battese and Coelli (1995). The results indicated that more efficient firms are the oldest. The total factor productivity of firms tended to fall, even after the end of quotas, increasing productivity only from 2007. Overall, firms from Santa Catarina were more efficient than those of other states.
