Foliar retention in soybean (Glyaine max (L.) Merril) as effected by levels and period of infestation with Piezodorus guildinii (Westwood, 1837) (Herniptera, Pentatornidae)
The effect of stinkbug on foliar retention in soybean was studied. Field tests were carried out in Guaiba, Rio Grande do Sul, 1974/75. Soybean plants were artificially infested at various densities of Piezodorus guildinii (Westwood, 1837), per 0,5m of row and at different stages of soybean development by means of isolation cages. Foliar retention occurred when plants were infested continuosly, from full to the complete physiological maturity of the seed. This phenomenon was not observed when infestations …
