Seleção de variedades de soja (Glycine Max (L.) Merril ): I. Analises Bromatológicas

O presente trabalho foi realizado com o fito de estabelecer uma seleção prévia entre 32 variedaeds de soja (Glycine max. (L.) Merril), com base nas análises bromatológicas das sementes. Foram determinados teores de umidade (U), cinzas (RM), proteína bruta (PB), gordura bruta ou extrato etéreo (EE), fibra bruta (F) e extrativo não nitrogenado (ENN). As análises da variância permitem tirar as seguintes conclusões: 1) Entre as variedades classificadas no grupo forrageiro e comestível, tem-se: Mandarin 8a (40,16% PB), Bicolor de Calai (39,64% PB) e Aliança (38,70% PB). 2) De acordo com a classificação estabelecida, para o grupo produtor de óleo, as variedades Lee, Hood, Lincoln (Blanco) Improved Pelican (2), Lincoln (Morado) e Improved Pelican (1), se destacam com 21,76, 21,65, 21,62, 21,35, 21,13 e 21,04% de EE respectivamente. 3) As variedades que apresentaram menor percentagem de fibra são: Hernónjn.0 107, Hood, Mogiana, Hill e Selection n.° 135, com 9,59; 9,62; 9,68; 10,02 e 10,12% F respectivamente. 4) Encontrou-se uma correlação positiva entre o teor de proteína bruta e o de cinzas.

Three new species of Cephalobium (Nematoda, Cephalobiidae) parasites of Gryllodes laplatae (Orthoptera, Gryllidae) from Argentina

Three new species of Cephalobium Cobb, 1920, C. laplata from City Bell, C. polidentatum from Lincoln and C. dispar from Gorina, parasites of Gryllodes laplatae Saussure, 1877 from Buenos Aires, Argentina, are described and illustrated. Cephalobium laplata can be differentiated by having the cheilostom with a dorsal unmovable tooth, telostom with three ventral little teeth and two ventral movable claw teeth and gubernaculum triangular and five pairs of genital papillae. Cephalobium polidentatum has cheilostom with a movable ventral tooth, prostom with four dorsal movable teeth and telostom with three teeth; gubernaculum triangular with projections and with one pair of preanal and six pairs of postanal papillae. Cephalobium dispar is characterized by having telostom with two wings around the spicules and one pair of preanal and six pairs postanal papillae.
