This survey had the aim to identify the mite fauna and mite ecologic interaction in rice culture, harvest 2010-2011, in Taquari and Cachoeirinha Counties, state of Rio Grande do Sul, Brazil. The mite population was biweekly evaluated on IRGA 424 and INTA PUITA CL cultivars in four areas where randomly sampled 20 plants/area. Fluctuation, ecologic indices and correlation between species and environmental factors were calculated. A total of 1,626 mites belonging to 14 species from 12 families were collected. Of the total specimens collected, 34.56% was on IRGA 424, in Taquari, 32.47% on IRGA 424-120 and 28.35% on IRGA 424-60, in Cachoeirinha and 4.61% on 1NTA PUIT,g, CL, in Taquari. Family Ascidae showed great richness, with four species, Lasioseius sp., Lasioseius sp., Proctolaelaps sp. and Cheiroseius sp.. Schizotetranychus oryzae Rossi de Simons (86.65%) was the phytophagous mite more abundant, while among the predators Neoseiulus paraibensis (Moraes and McMurtry) (6.88%) stood out. The population peaks of S. oryzae and N. paraibensis happened on March 2011. In all evaluated areas, the correlation between S. oryzae and N. paraibensis was positive, specially on IRGA 424-120 (r = 0.93, P = 0.006). 展开更多

Cadmium(Cd) is an element that is nonessential and extremely toxic to both plants and human beings. Soil contaminated with Cd has adverse impacts on crop yields and threatens human health via the food chain. Cultivation of low-Cd cultivars has been of particular interest and is one of the most cost-effective and promising approaches to minimize human dietary intake of Cd. Low-Cd crop cultivars should meet particular criteria, including acceptable yield and quality, and their edible parts should have Cd concentrations below maximum permissible concentrations for safe consumption, even when grown in Cd-contaminated soil. Several low-Cd cereal cultivars and genotypes have been developed worldwide through cultivar screening and conventional breeding. Molecular markers are powerful in facilitating the selection of low-Cd cereal cultivars. Modern molecular breeding technologies may have great potential in breeding programs for the development of low-Cd cultivars, especially when coupled with conventional breeding. In this review, we provide a synthesis of low-Cd cereal breeding. 展开更多
