“…However, the use of phosphine has been restricted due to the possibility of development of resistance in pest populations (Pimentel et al, 2007), and the utilization of methyl bromide has been limited because it is considered to be a depleting agent of the ozone layer (Bell, 2000). Consequently, there is an increasing interest of researchers in developing new insecticides for the control of insect pests in stored grains (Papachristos & Stamopoulos, 2004;Almeida et al, 2005;Negahban et al, 2007;Rozado et al, 2008;Pereira et al, 2008;Capps et al, 2010).
