[First occurrence of Biomphalaria straminea in the South Goiano, Brazil]. / Primeira ocorrência de Biomphalaria straminea no Sul Goiano, Brasil.

The objective of this note is to report the occurrence of the Biomphalaria straminea in the county of Cachoeira Dourada in the south of Goiás, and with that enhance the knowledge about its geographical distribution in the state. More than identify the species, the collection of thirty samples helped study and verify the presence of cercariae, especially because they were found in a setting which offers proper conditions to the development of a focal transmission site of schistosomiasis.

Parasitoids of the family Chalcididae collected in pastures and forests using yellow traps, in Itumbiara, Goiás, Brazil.

The objective of this study was to appraise the occurrence of parasitoids of the family Chalcididae in Itumbiara County, State of Goiás, central Brazil.

Samplings were performed weekly by placing 10 traps at soil level (5 traps in the pasture and 5 in the woods). During 1998, 121 specimens of Chalcididae were collected. Haltichella sp.4 was the most abundant species collected (15.7%).
