1. Contamination of corn grain for human consumption with transgenic sequences in Paraguay
Abstract Corn is one of the most important economic, social and cultural agricultural products in Paraguay, being the main ingredient of several typical foods. Due to the cross-pollination of this plant, it can be contaminated with transgenic maize pollen found in nearby fields. The general objective of this research was to evaluate the presence of transgeni

2. Risk of genetic vulnerability and aspects of the reproductive biology of Psychotria ipecacuanha (Rubiaceae), a threatened medicinal plant species of Brazilian forests
ABSTRACT Psychotria ipecacuanha, commonly known as Ipeca, is a medicinal plant of pharmacological and economic value. The species is distylous; it has populations with two floral morphs, one with long and one with short styles. Apart from the presence of two floral morphs in a balanced ratio (1:1), reciprocal herkogamy of the reproductive organs between alte

3. Nesting and reproductive habits of the solitary bee Centris analis in trap nests under a tropical climate
RESUMO A polinização é um fator essencial na produção agrícola mundial e existe a necessidade de aumentar o número de espécies de abelhas que podem ser criadas para a polinização na agricultura, como a abelha solitária coletora de óleo Centris (Heterocentris) analis (Fabricius, 1804). Aqui, os comportamentos de nidificação e reprodutivo dessa a

4. Bee assemblage in habitats associated with Brassica napus L.
ABSTRACTAssessments in agricultural crops indicate that alterations in the landscape adjacent to the crops can result in reduced productivity due to loss or low abundance of pollinating agents. In the canola crop, production is partially dependent on insect pollination. Therefore, knowledge of the faunal diversity within and near crop fields is key for the m

5. Honey bee visitation to sunflower: effects on pollination and plant genotype
Sunflower (Helianthus annuus L.) is an allogamic plant, which needs insects on flowering, especially the honeybees for seed production. Collecting nectar and pollen by honeybees in agricultural crops is essential to apiculture, as well as a better understanding of plant biology. The foraging behavior of Africanized Apis mellifera L. (Hymenoptera, Apidae) and

6. Sistema de Informações Geográficas destinado ao planejamento da atividade apícola no assentamento Padre Josimo Tavares- PA / Geografic Information System for the planning of the apicultural activity in Padre Josimo Tavares Settlement - PA
Today, apiculture is economically exploited by the man in the pollination of crops, as well as the production of propolis, royal jelly, bee venom and the best known and exploited by the man, the honey. Apiculture has been established as one of the most important activity in terms of economic, social and environmental, once employing family labor-intensive an

8. Mel de abelhas nativas e africanizadas do estado de Alagoas : composição química, segurança microbiológica e atividade terapêutica. / Honey of beens native and africanized state of Alagoas State : chemical composition,security microbiological and activity therapy.
The rational development of bees is one of the most promising agricultural activities, since it is essentially self-sustaining family and therefore helps to maintain and restore the environment, through their role in pollination, and guarantee income to the producer who employs his family on it. Honey is the main product of this activity, being generated by

9. Determinação da variabilidade genética nas populações de seleção recorrente de arroz CNA-IRAT 4 e CNA 12 utilizando marcadores microssatélites / Determination of the genetic variability in rice populations of recurrent selection CNA-IRAT 4 and CNA 12 using microssatellites markers
Recurrent Selection is a population inbreed method that is not traditionally used in autogamous species as rice. However, it is still an interesting methodology to the implementation of recurrent selection populations, due to the possibility of obtaining genotypes with wide genetic base and adequate agronomical traits. It is even more attractive when a great
