Electrical condutivity test in Jacaranda micacrantha seeds
Souza, Gabriela Fernanda; Garlet, Juliana; Delazeri, PricilaThe objective of this study was to evaluate the physiological quality of Jacaranda micranta Cham. seeds, by electrical conductivity test. We used three lots of seeds, stored for different periods. Electrical conductivity tests were conducted at different amounts of seeds and deionised water for soaking, and then they were associated with germination and vigour data. It was observed that the longer the seeds wer...

Musa acuminata pseudostem extract on the control of Atta sexdens rubropilosa
da Silva, Thais Cibeli; de Camargo, Alcilene Batista; Sanches, Laura Araujo; Garlet, JulianaCurrently, few active principles are authorized by the forest certification for the control of insect pests, with which it is necessary to develop new products, mainly aiming at lower environmental impact. The plants are able to develop substances called secondary metabolites, widely studied as an alternative form of pest control. Thus, the objective of this study was to evaluate the insecticidal potential of t...
Bark beetles in a mixed plantation of Bertholletia excelsa and Hevea brasiliens...
Monteiro, Marcelo; Garlet, Juliana; Carvalho, Camila CrausBark beetles (Curculionidae: Scolytinae) are wood borers with the potential to cause significant damage in forest plantations. Studies of this group are more common in plantations of Eucalyptus, and Pinus, but the increase of planting with other forest species, such as Brazil nut and rubber trees, indicates the need for monitoring of Scolytinae in these additional forest areas. Thus, the objective of this work ...

Soil fauna in initial planting of Eucalyptus under different alternatives to we...
Garlet, Juliana; Costa, Ervandil Corrêa; Boscardin, Jardel; Machado, Dayanna Nascimento; Pedron, Leandra; Machado, Leonardo MortariThe aim of this study was to investigate the effect of different chemical control of alternative weed in soil fauna in initial planting of Eucalyptus grandis. The treatments consisted of partial and full control of the weed vegetation. Collections were conducted through soil trap (pitfall). We collected 26,136 specimens, distributed in 13 taxonomic groups (Araneae, Blattodea, Chilopoda, Collembola, Coleoptera, ...
Arthropod bioindicators of environmental quality
Spiller, Márcia Soares; Spiller, Claiton; Garlet, JulianaThe phylum Arthropoda is one of the most diverse groups under the terrestrial surface comprising different classes of insects that occupy different environments. Some groups have a close relationship with the habitat they occupy, responding significantly to changes in the environment, thus indicating the level of change in the environment by their presence or absence. The present study aimed to demonstrate the ...
First occurrence of Terastia meticulosalis preying on seeds of Erythrina crista...
Pedron, Leandra; Costa, Ervandil Corrêa; Garlet, Juliana; Boscardin, Jardel; Machado, Dayanna do Nascimento; Bolzan, Lisandro CunhaThe present study aimed at identifying which insect species damages seeds of Erythrina crista-galli L. From November 2012 to January 2013, six E. crista-galli trees were selected in the city of Santa Maria, Rio Grande do Sul State, Brazil, and six pods were taken from each tree. Such pods, properly packaged and identified, were taken to UFSM’s forest pest laboratory and stored in plastic containers until the ad...
