“…However, its occurrence is more frequent in South America (Peredo 2002). In Brazil, it is the best-known species of the Scutelleridae, and its occurrence has been observed in the northeastern, southeastern, southern and central-western regions (Costa Lima 1940;Nava et al 2009;Broglio-Micheletti et al 2010;Rodrigues et al 2011). Besides having a wide geographic distribution, it is a polyphagus insect currently observed on more than 14 plant species, namely rice [Oryza sativa L. (Silva et al 1968;Gallo et al 2002;Sanchez-Soto & Nakano 2002;Santos et al 2005;Nava et al 2009).…”

“…However, the species Pachycoris torridus (Scopoli, 1772) is able to colonize the pinion, which gives the insect highlighted as agricultural pest of this culture vegetal. The fruits attacked by P. torridus become unviable presenting initially dark and deformed appearance, which results in subsequent fall and loss of product [5]. Thus, the damage caused by these insects to the fruits of physic nut has been reported to decrease the productivity of the oil used as a raw material for biodiesel [5,6].…”

“…Segundo Saturnino et al (2005), o pinhão-manso apresenta grande rusticidade e poucos registros de ataques de pragas, devido à exsudação de látex cáustico pela planta. Contrapondo essa afirmação, Micheletti et al (2010) registrou a presença de Pachycoris torridus (Scopoli, 1772) (Hemiptera: Scutelleridae) em pinhão-manso na região de Alagoas, Brasil. Outros relatos também foram feitos por Beltrão et al (2006) em observações preliminares Para determinar a massa de mil sementes, procedeu-se a pesagem em balança de precisão com resolução de 0,0001 gramas, sendo utilizadas oito repetições de 100 sementes.…”
