Infestation Of Aetalion Reticulatum (Linnaeus) (Hemiptera: Aethalionidae) In Plants Of Euterpe Oleracea Martius (Arecaceae) In Acre State, Brazil, Rodrigo Souza Santos Rss

The açai palm (Euterpe oleracea Martius) is a native palm tree from the Amazon region floodplains and may be indicated as the most economically profitable species of this genus. Its fruit pulp is extracted and widely consumed by the population of northern Brazil in several ways. With the expansion of the planted area many factors may affect the production and limit the cultivation, highlighting the occurrence of insect pests that cause losses in production. This report presents the first occurrence of the leafhopper Aetalion reticulatum (Linnaeus) (Hemiptera: Auchenorrhyncha: Aethalionidae) in E. oleracea plants. The occurrence of this insect associated with …
Mites (Arachnida: Acari) Collected On Rubber Trees Hevea Brasiliensis (Willd. Ex A.Juss.) Müll.Arg. In Santana, Amapá State, Brazil, Rodrigo Souza Santos Rss
Mites (Arachnida: Acari) Collected On Rubber Trees Hevea Brasiliensis (Willd. Ex A.Juss.) Müll.Arg. In Santana, Amapá State, Brazil, Rodrigo Souza Santos Rss

The purpose of this study was to elaborate a preliminary list of the mite species associated with rubber trees in the municipality of Santana, in the state of Amapá, Brazil. Two collections of rubber tree leaves were conducted on May 2nd and June 5th , 2010. Twenty-five plants were sampled at random. Three leaves were collected per plant, from the lower third of the crown. The samples were placed in paper bags, packed in an isothermal box chilled gel-based pulp plant (Gelo-X®), and transported to the Entomology Laboratory at Embrapa Amapá, in Macapá. The leaflets were examined under a stereomicroscope, …
New Models Of Emergence Traps For Endophytic Egg Parasitoids Capture, Rodrigo Souza Santos Rss
New Models Of Emergence Traps For Endophytic Egg Parasitoids Capture, Rodrigo Souza Santos Rss

For strain selection studies of natural enemies from the field, studies of behavior or even of taxonomy, capture of alive insects are of great importance. One alternative for obtaining adult parasitoids (Hymenoptera) is the use of emergency traps. Therefore, the objective of this work was to propose two models of emergency traps (traps like “box” and “bottle”), for obtaining alive endophytic egg parasitoids. The two models proposed were efficient in the capture of alive parasitoids, however a larger capture of specimens was observed in the “box” trap in relation to the e “bottle”, due to larger folioles storage inside the …
Diversity And Spatial Distribution Of Ground Arthropods In Agroecosystems, Rodrigo Souza Santos Rss
Diversity And Spatial Distribution Of Ground Arthropods In Agroecosystems, Rodrigo Souza Santos Rss
Rodrigo Souza Santos RSS
The knowledge of the diversity and distribution of ground arthropods contributes for the development of sustainable agricultural systems. This work was carried out at the Paulista State University, Jaboticabal campus, State of São Paulo, Brazil, during the period from February to April 2004. The objective was to analyse the community of Carabidae, Staphylinidae, Formicidae e Araneae through faunistic indexes, to determine the spatial distribution and interespecific interactions of predominant species in soybean (Glycine max (L.) Merr.), corn (Zea mays L.) and rubber tree (Hevea brasiliensis Muell. Arg.). The arthropods were sampled by pitfall traps distributed each 10 m in two …
