| Les expériences faites par certains armements américains et par le thonier senneur espagnol "Marinera" sur les côtes d'Afrique, nous ont amené à penser qu'on ne pouvait espérer obtenir un rendement satisfaisant de la senne qu'en "fixant" le banc de thon pendant la manoeuvre d'encerclement. L'expérience paraît bien confirmer ce point capital, au moins jusqu'à maintenant dans la zone de pêche prospectée, soit de Dakar à Abidjan, et avec le matériel utilisé. La pêche à la senne se déroule donc en 2 temps : 1° fixation et concentration des bancs de thon par appâtage ; 2° encerclement et capture du banc ainsi fixé. |

| Au cours des deux derniers siècles, plusieurs tentatives ont été faites pour subdiviser le genre Sepia ou pour classer les différentes espèces dans des catégories super-spécifiques ou super-génériques. C. von Linné (1758) avait classé tous les Céphalopodes en trois genres: Argonauta, Nautilus et Sepia. Ce dernier genre comprenait toutes les espèces sans coquille externe, dont une seule, Sepia officinalis L., est un Sepia dans le sens actuel. Presque deux cents ans plus tard, T. Iredale (1954, p. 81) a classé les coquilles des Sepiidae australiens en trois families, quatre sous-families et treize genres. Après la simple classification de C. von Linné, l'étude des Céphalopodes n'a fait aucun progrès pendant la seconde moitié du 18e siècle. C'est J. B. P. A.... |

| Eight root-knot nematode forms are known to occur in Brazil, namely Meloidogyne exigua, M. incognita, M. j. javanica, M. j. bauruensis, M. inornata, M. hapla, M. arenaria arenaria and M. coffeicola. After presenting a historical resume of the root-knot disease, as well as observations on symptoms, distribution and spread, and life history of the nematodes, a study of the morphological characters used in identification of species is made, a key for separating the forms referred to above being also prepared. As no information on host plants of the coffee root-knot nematode (M. exigua) was available, a few tests were performed, as an attempt to infect several plant species. Pepper (Capsicum annuun) was the only plant attacked by M. exigua, having failed all... |

| Gadus pollachius Linnaeus (Fig. 1) is generally known under the name of "lieu jaune" in France, but according to the region or its size, it can have other names: At Boulogne-sur-Mer, it is known as white "merluche" or "colin" and in Brittany, as "malouan" or "loeneck" according to whether it is a juvenile or an adult specimen.In England, it is called pollack or whiting pollack and in Scotland, "laits" or "lythe". In Spain, juveniles are called "corobelo" and adults "abadejo".While the development of eggs and larvae of whiting is well described, its biometry and its growth are less well known.The present study aims to contribute some data on this subject and to determine whether the whiting fished in the southern portion of their habitat, from Portugal to... |

| Uma série de três ensaios com nove inseticidas diferentes foi realizada para estudar seus efeitos sôbre o contrôle do tripes vector de vira-cabeça. Granutox-5, aplicado no solo, Folidol 60 (0,25%) e Dieldrex 20. (2,0%), em pulverizações foliares, apresentaram os melhores resultados; Metasystox (i) (0,4%) e Phosdrin C. E. 2 (1,0%), em pulverizações, também foram bastante promissores para o contrôle da moléstia. À redução na porcentagem de infecção com a moléstia nos melhores tratamentos não correspondeu grande aumento de produção, em comparação com a testemunha. Isto foi atribuído, em parte, ao efeito fitotóxico de alguns inseticidas, uma vez que foram aplicados em concentrações bem mais elevadas do que as recomendadas pelos fabricantes. |
