New record of predatory ladybird beetle (Coleoptera, Coccinellidae) feeding on extrafloral nectaries Rev. Bras. entomol.
Almeida,Lúcia M.; Corrêa,Geovan H.; Giorgi,José A.; Grossi,Paschoal C..
New record of predatory ladybird beetle (Coleoptera, Coccinellidae) feeding on extrafloral nectaries. Feeding by Exoplectra miniata (Germar) on extrafloral nectaries of Inga edulis Mart. was observed in Nova Friburgo, Rio de Janeiro, Brazil. This is the first record of this behavior for Exoplectrini.

Phosphorus Fertilization Increases Biomass and Nutrient Accumulation Under Improved Fallow Management in a Slash-and-Mulch System in Eastern Amazonia, Brazil Rev. Bras. Ciênc. Solo
Rangel-Vasconcelos,Lívia Gabrig Turbay; Kato,Osvaldo Ryohei; Vasconcelos,Steel Silva; Oliveira,Francisco de Assis.
ABSTRACT Improvement of fallow vegetation can have a positive impact on the productivity of slash-and-mulch systems in eastern Amazonia. Phosphorus fertilization can increase biomass and nutrient stocks in the fallow phase, thereby improving nutrient cycling and crop productivity. Here, we compared biomass and nutrient stocks under three fallow management strategies: (1) natural fallow (regrowth vegetation) - NF; (2) NF vegetation improved with leguminous trees (Sclerolobium paniculatum Vogel and Inga edulis Mart.) - IF; and (3) NF vegetation improved with leguminous trees plus phosphorus fertilization - IF+P. We quantified above- and belowground biomass and N, P, K, Ca, and Mg stocks after 23 months of fallow. The IF+P increased aboveground (leaf + branch...
