Proteolytic activity (as indicated by Abs450 min−1 mg protein−1) and inhibition of azocasein hydrolysis by specific protease inhibitors in extracts of Callosobruchus chinensis and three parasitoid species.

aL = larvae; F = females.bValues are means ± SE of triplicate measurements for a unique pool of extracts.cThe percentage of inhibition was calculated as [1-(activity with an inhibitor/activity in control) ×100]. Inhibition was measured at the optimum pH.Protease inhibitors abbreviations: PMSF (phenylmethylsulphonyl fluoride), SKTI (soybean Kunitz trypsin inhibitor), E-64 (L-trans-epoxysuccinyl-leucylamido-(4-guanidino)-butane), IAA (iodoacetamide), EDTA (ethylenediaminetetraacetic acid).“ni”: inhibition “nd”: not determine.
