The distribution of digestive proteinases in either the anterior and posterior midgut or between the midgut epithelium and ectoperitrophic and endo-peritrophic spaces in the midgut were examined in the European corn borer, Ostrinia nubilalis. Trypsin

Digestive proteinases in two maize feeding, stored-product insects, Sitophilus zeamais Motschulsky and Prostephanus truncates (Horn), were identified by determining the pH for maximal hydrolysis of synthetic protease substrates and the effects of pot

The effects of maize-derived compounds, DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one) and MBOA (6-methoxybenzoxazolinone), on detoxification enzymes of the European corn borer, Ostrinia nubilalis (Hubner), were examined. In vitro , DIMBOA inc

The maize derived growth inhibitor, 2,4-dihydroxy-7-methoxy-l,4-benzoxazin-3-one (DIMBOA), and one of its degradation products, 6-methoxybenzoxazolin-3-one (MBOA), were assessed for their mode of action on larvae of the European corn borer, Ostrinia

Detoxification processes in the European corn borer, Ostrinia nubilalis , fed on either meridic diet or corn leaves from three plant lines with either low, intermediate, or high resistance to leaf damage were investigated by measuring cytochrome P450

Since the first observation that plants contained protease inhibitors, as identified by their ability to inhibit vertebrate enzymes, it has been postulated that the presence of these substances was related to their phytoprotective abilities. However

The midgut of the yellow mealworm, Tenebrio molitor, contains both serine and cysteine proteolytic activities, identified using synthetic substrates, pH optima characteristic for each enzyme, diagnostic activators and inhibitors. The cysteine protein

European corn borer, Ostrinia nubilalis, were fed artificial diet containing either 1% (w/v) soybean, 2% (w/v) chicken ovomucoid or 1% (w/v) corn trypsin inhibitor and effect on digestive protease activity, larval weight and midgut protein were deter

The larval midgut of the Colorado beetle, Leptinotarsa decemlineata contains cathepsin B, D and H activity detected by use of haemoglobin, synthetic substrates specific for each enzyme, pH at which the substrate was maximally hydrolysed and effects o

The biochemical basis for the tolerance of the European corn borer,Ostrinia nubilalis, to the phototoxinα-terthienyl was investigated by measuring the midgut polysubstrate monooxygenases and glutathioneS-transferase activities.α-Terthienyl administ
