Ciência Rural , 2011, DOI: 10.1590/S0103-84782011000100017
Abstract: the caterpillar dichomeris famulata meyrick, 1914 (lepidoptera: gelechiidae) is a new pest of corn ear in brazil, and its study is important in seed fields. the aim of this was to study the biology of this pest under laboratory conditions (25±2°c, 65±10% of rh and 14-hours of photophase). the biological cycle (egg-adult) was of 35.2 days. the incubation period was of 4.1 days. the average larval development time was of 21.1 days, and 5 instars were observed. the pupal period was of 8.4 days and the pupae weight was of 12.4 and 11.3 mg for males and females, respectively. the females laid an average of 118 eggs with a pre-oviposition period of 10.7 days and an oviposition time of 14.0 days. the mean longevity of males and females was of 37.02 and 44.16 days, respectively, and sex ratio was of 0.48. the caterpillars damage the silks and grains at the milk stage through little entry orifices, damaging the endosperm and, more importantly, the embryo, reducing the seed germination. these results can support the establishment of strategies to manage this new corn ear pest, especially in seed fields.

Mercados campesinos y diferenciación social en la transición al capitalismo
Colombo,Octavio;
Mundo agrario , 2004,
Abstract: the transformation processes that affected the european peasantry in the late middle ages have long been considered essential in order to study the transition from feudalism to capitalism. this work analyzes the way in which the process of social differentiation and the development of local markets in 14th and 15th c castile are related. in the first place, different historiographic theses are examined. they all share a logical-abstract approach to the problem, neglecting the specific manner in which peasant markets operate. next, an alternative hypothesis is put forward in contrast. based on the analysis of documents from the town of avila, this hypothesis reveals the existence of forms of unequal exchange, which enable capitalist accumulation at village level and create the conditions for the emergence of a modern class structure.

Abstract: social sciences are now being challenged to think on the world's globalization. at the end of the twentieth century and dawn of the twenty first, they are faced with the dilemas that open up with the globalization of things, people and ideas: there are social, economical, political, cultural and other processes and structures that are just begining to be studied. besides what is local, national and regional, new and fundamental problems appear with the rising global society. the geographic, historical, cultural and civilizatorian limits seem to change in surprising ways and directions. the individual, group, class, colectivity and people are put before other horizons. the scientific thinking itself is called upon to elaborate concepts and interpretations to account for little known realities. the globalization theories that are just being sketched show the efforts of social sciences to explain what is new going on in the world.
