Análise da produção e comercialização de mel natural no Brasil no período de 1999 a 2010

The aim of this study was to analyze the evolution of natural honey production in Brazil, as well as the Brazilian performance in the international markets and their own consumption behavior of natural honey in the domestic market. For this study, we used descriptive analysis of time series information, data production and export of natural honey understood, respectively, for the periods 1999 to 2010. To analyze the correlation between the series of apparent consumption per capita (variable X) and the international price data (variable Y), we used the statistical analysis of the correlation coefficient of Pearson (CP). Main results revealed that the Brazilian production of natural honey has more than doubled in the last decade, while the Northeast region was the largest contributor to this performance. This increase in the production was mainly directed towards supplying the international market, which currently consumes more than half of Brazilian production. It is true that the change in the international market price has a direct effect on domestic supply, but the Brazilian domestic market has potential for increasing effective consumer who deserves to be better exploited; it implies to pay attention to the supply of quality natural honey, quantity and regularity.

Effects of neem oil (Azadirachta indica A. Juss) on midgut cells of predatory larvae Ceraeochrysa claveri (Navás, 1911) (Neuroptera: Chrysopidae)

The effects of ingested neem oil, a botanical insecticide obtained from the seeds of the neem tree, Azadirachta indica, on the midgut cells of predatory larvae Ceraeochrysa claveri were analyzed. C. claveri were fed on eggs of Diatraea saccharalis treated with neem oil at a concentration of 0.5%, 1% and 2% during throughout the larval period. Light and electron microscopy showed severe damages in columnar cells, which had many cytoplasmic protrusions, clustering and ruptured of the microvilli, swollen cells, ruptured cells, dilatation and vesiculation of rough endoplasmic reticulum, development of smooth endoplasmic reticulum, enlargement of extracellular spaces of the basal labyrinth, intercellular spaces and necrosis. The indirect ingestion of neem oil with prey can result in severe alterations showing direct cytotoxic effects of neem oil on midgut cells of C. claveri larvae. Therefore, the safety of neem oil to non-target species as larvae of C. claveri was refuted, thus the notion that plants derived are safer to non-target species must be questioned in future ecotoxicological studies. © 2012 Elsevier Ltd.
