Abstract

The accumulations of three main energy sources: triacylglycerol, polysaccharide and soluble protein were determined in two psocids, Liposcelis bostrychophila check for this species in other resources Badonnel and L. entomophila check for this species in other resources (Enderlein). The results indicated that the reserves of three energy sources in L. entomophila were significantly higher than that in L. bostrychophila. Exposure of the two psocids to chlorpyrifos and carbosulfan was associated with a significant change of the reserves, and the change range for L. entomophila was greater than for L. bostrychophila. The triacylglycerol responded to the two insecticides with a parabolic increase in the reserves, while polysaccharide and soluble protein responded with an enhancement of the utilization rates. These changes suggested that under the effect of chlorpyrifos and carbosulfan, polysaccharide and soluble protein are the main energy sources, while the utilization of triacylglycerol decreased.
