Evaluating potential olive orchard sugar food sources for the olive fly parasitoid Psyttalia concolor

Olive fruit fly Bactrocera oleae (Rossi) (Diptera: Tephritidae) is a major olive pest in the Mediterranean basin where increasing insecticide resistance has enhanced damage and necessitates more reliance on other control strategies, such as biological control. Provision of floral resources has been reported to improve the effectiveness of natural enemies. Here, we tested the effect of six plant nectars and two honeydew sources on the survival of Psyttalia concolor (Szépligeti) (Hymenoptera: Braconidae), a parasitoid wasp used in the biological control of olive fruit fly. Our results showed a positive effect on survival associated with nectars of Anchusa azurea Mill., Rosmarinus officinalis L., Lavatera cretica L. and Calamintha nepeta (L.) Savi, while honeydew proved to be a valuable alternative food source. When offering flowers directly to insects, Anchusa azurea, Lavatera cretica, and Foeniculum vulgare L. were found to be the most beneficial species, indicating also that P. concolor feeds predominantly on shallow corollas.

Winter cover crops on weed infestation and maize yield.

The establishment of commercial crops in succession to winter cover crops that leaves a dense straw layer provides significantly suppression of weeds. The objective of this work was to evaluate the suppressive potential of winter cover crops on weed infestation in maize and its effect on the yield of the maize sown in succession.

Efeito da adubação nitrogenada na incidência do pulgão Cerosipha forbesi (Weed, 1889) em morangueiro Fragaria vesca L.

Com o objetivo de examinar o efeito da adubação nitrogenada na incidência do pulgao Cerosipha forbesi, foi instalado em maio de 1991, no campo experimental da EMBRAPA - CNPDA, em Jaguariúna,SP, um experimento em blocos causalizados com 4 repetições e 3 tratamentos, sendo T1, testemunha com 0 grama de sulfato de amônia por parcela; T2 com aplicação de 200 gramas de sulfato de amônia por parcela e T3 com 2000 gramas de sulfato de amônia por parcela. Cada parcela constou 4 fileiras com 10 plantas cada, sendo a parcela útil as duas fileiras centrais menos as plantas das extremidades. A avaliação foi feita em dezembro de 1991, tomando-se ao acaso 5 plantas da parcela útil, nas quais foram constados os pulgões encontrados. Os dados originais receberam transformação de arco-seno raiz quadrada de y. A maior incidência de pulgões foi verificada no tratamento testemunha - (7,712), seguido de tratamento T3 (4,249) e T2 (2,607). Não Houve diferença significativa pelo teste de Ducan ao nivel de 5% entre os tratamentos T1 e t2. Nesse experimento nao se verificou aumento da incidência do pulgão com o aumento da dose de nitrigenio.

Proposta di traduzione di The Boy Who Could Fly di Sally Gardner: tradurre letteratura gender positive per giovani lettori

Questa tesi presenta la proposta di traduzione del romanzo "The Boy Who Could Fly" della scrittrice e illustratrice britannica Sally Gardner, e nasce dall’interesse per i modelli maschili positivi nella letteratura per l’infanzia e per ragazzi. Il libro fa parte della bibliografia del progetto G-Book, progetto finanziato dall’Unione Europea e a cura del Centro MeTRa dell’Università di Bologna volto alla promozione della letteratura gender positive per l’infanzia e per ragazzi. L’autrice tratta con ironia argomenti delicati come la valorizzazione della diversità e le relazioni familiari e tra coetanei. La tesi è suddivisa in quattro capitoli. Il primo capitolo è dedicato all’evoluzione della letteratura per l’infanzia e per ragazzi in una prospettiva gender positive, al ruolo della scuola nell’educazione alla lettura e alla sensibilizzazione per un’effettiva uguaglianza di genere e ai principali atti legislativi. Vengono presentati il Centro MeTRa, il progetto G-Book, l’analisi delle pubblicazioni per fasce d’età e delle relative questioni traduttive e, da ultimo, viene affrontato il rapporto degli italiani con la lettura. Il secondo capitolo contiene una presentazione dell’autrice, delle sue opere, dei caratteri salienti del romanzo e dei temi affrontati. Nel terzo capitolo viene esposta la scelta relativa al tema della presente tesi, ovvero i male characters e come i modelli maschili positivi possano avere un’influenza nella lotta per la parità di genere e per il superamento degli stereotipi. In questa parte dell’elaborato viene analizzata più a fondo la bibliografia G-Book e vengono presentati i capitoli del romanzo che sono stati tradotti. Il quarto capitolo comprende il commento alla traduzione e la tesi termina con due possibili collocazioni editoriali di The Boy Who Could Fly e la scheda di lettura del libro.

Discovery Of A Rare Pterosaur Bone Bed In A Cretaceous Desert With Insights On Ontogeny And Behavior Of Flying Reptiles.

A pterosaur bone bed with at least 47 individuals (wing spans: 0.65-2.35 m) of a new species is reported from southern Brazil from an interdunal lake deposit of a Cretaceous desert, shedding new light on several biological aspects of those flying reptiles. The material represents a new pterosaur, Caiuajara dobruskii gen. et sp. nov., that is the southermost occurrence of the edentulous clade Tapejaridae (Tapejarinae, Pterodactyloidea) recovered so far. Caiuajara dobruskii differs from all other members of this clade in several cranial features, including the presence of a ventral sagittal bony expansion projected inside the nasoantorbital fenestra, which is formed by the premaxillae; and features of the lower jaw, like a marked rounded depression in the occlusal concavity of the dentary. Ontogenetic variation of Caiuajara dobruskii is mainly reflected in the size and inclination of the premaxillary crest, changing from small and inclined (∼ 115°) in juveniles to large and steep (∼ 90°) in adults. No particular ontogenetic features are observed in postcranial elements. The available information suggests that this species was gregarious, living in colonies, and most likely precocial, being able to fly at a very young age, which might have been a general trend for at least derived pterosaurs.

Caracterização morfológica das sementes e plântulas de seis espécies invasoras do gênero Solanum L

Morphological caracterization of the seeds and seedlings of six weed especies of the genus Solanum L. The seeds of the genus Solanum are very similar, however, the association of their external characteristics with the anatomical features, such as hilum shape, the texture and the type of the seed coat sculptures, as well as the curved (circulated or coiled) shape of the embryo, are parameters of great importance in the taxonomical identification at the species level. It is are presented the morphological descriptions of the genus Solanum and a more detailed description of each studied species in terms of seed and seedling structures, including illustrations and taxonomical keys for the identification of Solanum aculeatissimum Jacq., S. americanum Mill., S. ciliatum Lam., S. sisymbriifolium Lam., S. sordidum Sendt. e S. viarum Dunal. There are also indications of the common names, the type of reproduction and dispersion, the crops in which the species is considered as a weed and the agricultural seeds in which it is found as a weed seed.

Fire management and the nesting of Athene cunicularia (Aves, Strigidae) in grasslands in central Cerrado, Brazil

Fire management is a common practice in several reserves in the Cerrado, but its influences on bird reproduction remain unknown. In addition, the nesting biology of the Burrowing Owl (Athene cunicularia) has been studied in numerous environments, but not in tropical grasslands managed by fire. This study examined the effects of fire management on the nesting biology of A. cunicularia in Emas National Park, State of Goias, central Brazilian Cerrado. We compared the number of breeding pairs and their burrows in October and November 2009 at 15 study sites in grasslands managed by fire (firebreaks) and unmanaged grasslands adjacent to and distant from firebreaks. We visited active burrows two-four times and described the burrow entrances and sentinel sites and counted and observed adults and young. A total of 19 burrows were found at firebreaks. One and two burrows were found in grasslands adjacent to and distant from firebreaks, respectively. For all burrows found, one to three young reached the adult size, being able to fly and/or run in early November. The 22 burrows found were in the ground, associated or not with termite and ant nests. Most (86.4%) burrows had only one entrance. Only three burrows had two or three entrances. Structures used as sentinel perches by adults were mounds in front of the burrow entrances, termite nests, shrubs and trees. Most of these sentinel sites were shorter than 2 m high and located less than 10 m from the burrow entrance. At Emas National Park, firebreaks appear to provide more attractive conditions to the nesting of A. cunicularia than unmanaged grasslands, likely because of the short herbaceous stratum due to frequent burning of firebreaks. This study suggests that fire management provides suitable conditions for the successful reproduction of A. cunicularia in firebreaks at Emas National Park.

A new species of Pacholenus Schoenherr from southeastern Brazil (Coleoptera, Curculionidae, Molytinae), and new occurrences of species of the genus

A new species of Pacholenus Schoenherr from southeastern Brazil (Coleoptera, Curculionidae, Molytinae), and new occurrences of species of the genus. Pacholenus monteiroi sp. nov. (type-locality Brazil, Rio de Janeiro state, Carapebus, Parque Nacional da Restinga de Jurubatiba) is described and illustrated. The weevil develops as a stem gall-former in Calyptranthes brasiliensis Spreng (Myrtaceae). The new species is easily distinguished from the other five known of the genus by the presence of a prominent supra-ocular ridge. An updated key for identification for all species of Pacholenus is provided. Three species of Pacholenus are presently recorded for the states of Rio de Janeiro and São Paulo; P. pelliceus and P. monteiroi occur in both states, while P. penicillus is only known from Rio de Janeiro; P. hispidus occurs in São Paulo, being the most widespread species of the genus, ranging from Minas Gerais south to Santa Catarina.
