| ABSTRACT: In recent years, Brazil has encouraged the cultivation of pecans to meet both demands of domestic and international market of nuts. New genetic varieties of pecans have been selected in recent years, but available scientific information on the occurrence of fungi and aflatoxins in the international literature is out of date. Therefore, the present study aimed to quantify and identify fungal microbiota and the presence of aflatoxins in pecan nuts cultivated in southern Brazil. Fifty-two pecan nut lots (Barton variety) were obtained from producers from 19 cities of Rio Grande do Sul State and analyzed by direct plating in Agar Dichloran Glycerol 18% (DG18) and Aspergillus Flavus and Parasiticus Agar (AFPA), following incubation at 25 °C for 7... |

| ABSTRACT Forest species can have their seeds damaged by granivorous insects, especially by those in their larval stage. In this context, this study aims to report the occurrence of Amblycerus species in Cordia trichotoma seeds, to describe their main damage to seeds and effects on germination, as well as their associated hymenopteran parasitoids. Therefore, seven trees were selected in the municipality of Taquaruçu do Sul, RS, Brazil. Fruits were collected weekly from the medium third of the tree crown, from the beginning of their formation until total dehiscence. To examine the damage caused by granivorous insects within the fruits, 15 fruits from each tree were sectioned with a scalpel. Furthermore, 10 fruits from each tree were stored individually in... |
