Resistance of Bt transgenic maize to lesser cornstalk borer (Lepidoptera: Pyralidae).

To determine if Bt maize seedlings are protected against lesser cornstalk borer damage, Bt hybrids at the 3 and 4 leaf stages were tested under temperatures between 20-32oC and artificial infestation. A high level of resistance was reported in all Bt maize as expressed by larval survival, larval weight, damage score, and number of surviving plants. All Bt maize protected plants against lesser cornstalk borer damage. Also, the resistance present in the Bt maize was not affected by daytime temperature.

Composição bromatológica do soro de leite bovino proveniente do processo de fabricação do queijo Mozarela.

Resumo: Objetivou-se avaliar a composição bromatológica do soro de leite bovino derivado da fabricação do queijo mozarela. Foram coletadas três amostras de 500 mL diretamente do tanque de uma fábrica de beneficiamento de queijo tipo mozarela na cidade de Damolândia em Goiás. Foram realizadas análises de matéria seca, umidade, matéria orgânica, cinzas e proteína bruta. O resultado para proteína bruta foi baixo, porém o tipo processamento usado na produção do queijo pode ter influenciado nesse resultado. [Chemical composition of bovine whey derived of processing of mozzarella cheese]. Abstract: The aim of experiment was to evaluate the Chemical composition of bovine whey derived of processing of mozzarella cheese. Three samples of 500 mL were collected in tank of a factory's processing of mozzarella cheese localized on Damolândia city, Goias. The analisys dry matter, moisture, organic matter, ash and crude protein were realized. Low results of crude protein was observed, however the kind of processing of cheese can influenced in this result.
