PICANCO, Marcelo; LEITE, Germano Leão Demolin; MENDES, Márcio C.  y  BORGES, Valdivino Enedino. Attack of Atarsocoris brachiariae Becker, a new pest of pasturelands in Mato Grosso, Brazil. Pesq. agropec. bras. [online]. 1999, vol.34, n.5, pp. 885-890. ISSN 1678-3921.  http://dx.doi.org/10.1590/S0100-204X1999000500022.

The effect of soil texture, landscape, grass species, age and system of pasture formation on attack intensity of Atarsocoris brachiariae Becker was studied. No differences were found among grass species or landscape on attack intensity of this bug. Higher densities of A. brachiariae were observed in sandy soils, in pastures over four years old, in those with traditional formation and between 20-30 cm underground. Attack of A. brachiariae occurred in patches specially in the transition areas between dead grass and normal growing grass.
