Coró-da-soja-do-cerrado Phyllophaga capillata (Blanchard) (Coleoptera: Melolonthidae) : aspectos bioecológicos.
ABSTRACT: In recent years, white grubs (Coleoptera: Melolonthidae) have become a serious problem in soybean crops Glycine max (L.) Meril in the "Cerrado" of Brazil (Middle-Western Region). The genus Phyllophaga Harris has been suggested by many authors as one of the most serious pests in diverse crops in Latim America. In Brazil, the most important species of this genus occur mainly in the south of the country, and are P. cuyabana (Moser) in soybean and P. triticophaga in wheat. In the "Cerrado" of Federal District and state of Goiás the specimens of the white grub. damaging soybean, were identified as P. capillata (Blanchard). Expensive and systematic yield losses caused by P. capillata have been observed in large soybean commercial areas. Crops sown in November show symotoms following the initial stage of larval development. Small and yellowish plants either die or have reduced yield potential. These symptoms occur in patches of variable size in a non-uniform pattern within agricultural fields. The objective of this publication was generating information about some aspects of the bioecology of P. capillata that can be used for the development of strategies for management of this new pest.
