L-Pyroglutamyl-L-phenylalanyl-L-leucine-p-nitroanilide (PFLNA)--a convenient chromogenic substrate for assay of thiol proteinases papain, ficin, and bromelain--was prepared by enzymatic synthesis with chymotrypsin as a catalyst. The thiol proteinases hydrolyze PFLNA with the liberation of p-nitroaniline, estimated spectrophotometrically by its absorbance at 410

Plants and insects have coexisted for million years and evolved a set of interactions which affect both organisms at different levels. Plants have developed various morphological and biochemical adaptations to cope with herbivores attacks. However, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)

Enzymes play a key role in insect-plant relationships. For a better understanding of these interactions, we analyzed Tuta absoluta digestive enzymes. Here, we describe a detailed protocol for the detection of trypsin and papain-like enzymes in Tuta absoluta larvae by
