Corythaica cyathicollis (Costa, 1864), aspectos sistemáticos, biológicos e econômicos (Hemiptera, Tingidae)

The present work deals with the systematic, biological and economic problems related to Corythaica cyathicollis (Costa, 1864) (Hemip., Tingidae). In the first part are presented the generic characteristics of Corythaica and is discussed the status of the specific name. The validity of C. cyathicollis, as stated by DRAKE and his collaborators, was denied by MONTE in his last works, he considered the species as C. passiflorae. Even in the modern literature no agreement has been achieved and three names are still used (cyathicollis, passiflorae and planaris) to designate the same insect. In order to resolve definitively this problem, a Neotype is designed to fill the place of the missing type of C. cyathicollis. Also in the first parte is discussed the taxonomic value of both male and female genitalia. The whole male copulator apparatus is studied and are illustrated the genital capsules of 8 species of this genus. Special mention is made of the shape of the basal plates and the proportions of the segmental membrana. The female genitalia is studied based upon the work of FELDMAN & BAILEY (1952). In the second part the biological cycle of C. cyathicollis is carefully studied. Descriptions of the egg are done and the ways of oviposition. The number of eggs laid by the female was observed to be about 350, during a period of more than 45 days. The eclosion of the neanide I is illustrated in some of its phases and the 5 larval instars are described and illustrated. Ending this part are included the lists of parasites and predators observed as well as the plant hosts. The actual geographical distribution is presented, based chiefly on HURD (1945). The economic problems concerning this species are reported in the third part of the work, and the ways of control are discussed. An experiment was carried out involving 4 insecticides: Malathion and Parathion, commonly used against this "lace bug"; Toxaphene and Dimethoate (American Cyanamid 12.880), the last one is an insecticide recently introduced in Brazil and was not previously used for these purposes, but gave the best results and it is quite able to control these insects even on crops showing highly developed infestations.

Sôbre o Phlebotomus Brasiliensis Costa Lima, 1932 (Diptera, Psychodidae)

In 1939, Mangabeira obtained, under laboratory conditions, the development of eggs of Phlebotomus brasiliensis Costa Lima, 1932, collected at Lassance (typical locality), Minas Gerais, Brasil. He then studied the female and immature stages of this Phlebotomus. The results of these observations plus some more recent data on the male, geographical distribution and bionomics are presented. Morphologically it is closest to Phlebotomus runoides. However, the male Phlebotomus brasiliensis differs from all other Phlebotomus because of its very long spicules, similar to those of Brumptomyia. The female differs by its longer ducts, and by possessing only four horizontal teeth in the buccal cavity, whereas P. runoides has approximately 12 teeth. The pupae of P. brasiliensis is characterized by its two pre-alar setae, which are very simple and small and by the abdominal setae, which are not planted on a protruding tubercle. The fourth stage larvae main characteristics are very thin antennae, inserted on a protruding tuberculum, and slightly brush-like hind frontal setae. P. brasiliensis is here reported, for the first time, for the State of Bahia (Cachoeira, Pojuca and Salvador). The species has almost always been found in armadillo burrows. In the State of Bahia it is more frequent during the dry season. Under laboratory conditions, the female lays about 53 eggs.

Technological trampolines for new venture creation in Catalonia: the case of the University of Girona

Recent trends in technology transfer show an intensification of spin-off creation as a modality of university research commercialisation, complementary to the conventional ones, contract research and licensing. In this paper we analyse the evolution, objectives, resources and activities of a specialised unit –Technological Trampoline (TT) - in charge of new venture creation at the University of Girona (Catalonia-Spain). Based on two theoretical frameworks, Resource-based-view and Institutional Theory, we adopt a multi-dimensional approach to study the strategy of spinning-off new ventures at the University of Girona in terms of resources and activities, how this process is organised and if the outputs fit with this UdG’s objectives and the local environment. Our main contribution is an in-depth analysis of the spin-off creation unit with special emphasis on its variety of resources and activities. The results have a series of implications and recommendations at both university and TT level.

Sôbre dois novos parasitos de peixe da costa do Peru (Cestoda, Tetraphyllidea)

Na presente nota estudamos alguns cestódeos coletados de Sarda chilensis (Cuv.) peixe comum da costa do pacífico, enviado por um de nós (N.I.H); o material era constituído por vários espécimes de Phyllobothriidae e paenas trêss de Onchobothriidae, infelizmente todos comprimidos; não obstante aqui fazemos o seu estudo por ser tratar de material de interêsse.

Milk, from medicine to food Mediterranean Europe: Catalonia, 19th-20th centuries

The spread of milk consumption was a significant change in the diet of Europeans, however it is one that has not been greatly studied with regard to the populations of Mediterranean Europe. In this article we shall analyse the ain circumstances that conditioned that process in Catalonia between the middle of the 19th century and 1936. In our study we shall argue that the consumption of milk in this area was only relevant in the 19th century in situations of illness or old age, and that it subsequently increased and acquired a new significance as a result of various factors. In particular, we shall emphasise: (a) the scientific advances in microbiology and nutrition, (b) the activities carried out by doctors and various public institutions to promote the consumption of fresh milk, and (c) the technological innovations in the milk producing sector. In Appendix 1 we show two maps representing the main territorial references that we shall mention.
