“…The properties of amylase, trypsin and aminopeptidase from S bipunctata are similar to those from other insects (see references in Vonk and Western, 1984;Applebaum, 1985;Ferreira and Terra, 1986;Baker, 1989;Lemos and Terra, 1992 Baker, 1991;Jordão and Terra, 1991 (Santos and Terra, 1986;Terra et al, 1987). This finding lends further support to the assertion (Terra, 1988(Terra, , 1990 (Sakagami et al, 1965).…”

“…Recent studies suggest that it is likely that larval Lepidoptera, and phytophagous insects in general, do digest some cellulose and more fibre than previously thought (Terra et al, 1987;Pant & Ramana, 1989;Ferreira et al, 1992), although most studies focus on cellulose digestibility and not overall fibre digestibility. This study does not identify the constituent of fibre that is being digested although it is likely that some cellulose and hemicellulose are being digested (Terra et al, 1987;Ferreira et al, 1992). The presence of cellulose digesting enzymes has been reported for some leaf feeding Lepidoptera (Pant & Ramana, 1989) although production of these enzymes is uncommon among animals (Martin, 1991).…”

“…The technique used by Terra et al (1987) to examine the nutritional ecology of E. ello and by Ferreira et al (1992) to examine digestion in the grasshopper Aracris flavolineata De Geer (Orthoptera: Acrididae) provides significantly more information about the digestion of particular cell wall components of plants.

“…Phytophagous insects with chewing mouthparts generally digest very little of the cell wall component (or fibre) of the plant they consume (Terra et al, 1987, Abe & Higashi 1991Hochuli et al, 1993). A considerable body of evidence suggests that cellulose is indigestible to a majority of insects (Martin, 1991;Douglas, 1992;Slaytor, 1992) but evidence regarding the significance of fibrous diets and fibre indigestibility to insect nutritional ecology is equivocal (Slansky, 1990).…”

“…Caterpillars may obtain easily digestible cell contents as these leak through plasmodesmata or the cell wall, whereas gut conditions are likely to prevent this occurring in leaf feeding Orthoptera ( Barbehenn, 1992). Terra et al (1987) showed that larvae of Erinnyis ello (Linnaeus) (Lepidoptera: Sphingidae) digested some hemicellulose but not cellulose, demonstrafing that cell contents may be liberated by chemical breakdown of the cell wall.…”

Final instar Persectania ewingii (Westwood) (Lepidoptera: Noctuidae) were fed seedling Triticum aestivum L. for 2 days to determine the approximate digestibility of the cell wall and cell content fractions. Cell wall content was estimated using a micro-analytical neutral detergent fibre technique. Approximate digestibilities of neutral detergent fibre, neutral detergent solubles and dry matter were calculated for individuals and pooled samples. P. ewingii larvae digested a small but significant proportion of the fibre ingested (13-21%), higher than that previously reported for herbivorous insects. The micro-analytical and previously used macro-analytical techniques produced similar estimates of digestibility although both techniques have inherent shortcomings, the latter requiring the pooling of samplex and the former limiting the number of replicates during chemical analysis. Differences in the amount of larval frass collected during the feeding trial (corrected for consumption) explained much of the variation in digestibility values, while there were no effects of larval mass, overall consumption and total frass produced on digestibility estimates. These results confirm that plant cell contents are the major source of nutrients to larval Lepidoptera although there is some chemical disruption of the plant cell wall.

Based on polyacrylamide gel electrophoresis, density-gradient ultracentrifugation and thermal inactivation, there i s only one major molecular species of each of the following larval enzymes (soluble in water or solubilized in Triton X-100): membrane-bound aminopeptidase (pH optimum 8.5; K , 0.21 m M L-leucine p-nitroanilide; M, 322,000), amylase (pH optimum 6.5; K , 0.14% starch; M, 66,000), lysozyme (pH optimum 3.5; K , 0.3 mg/ml; M, 24,000); and membrane-bound trehalase (pH optimum 5.0; K , 1.09 m M trehalose; M, 94,000). Except for lysozyme, the properties of adult digestive enzymes are different from those described for larval enzymes. Larval aminopeptidase and trehalase were purified by electrophoresis and larval lysozyme (contaminated with amylase) by density-gradient ultracentrifugation, and were used to raise antibodies in a rabbit.Antibodies raised against larval aminopeptidase, trehalase, and amylase did not recognize the imaginal enzymes, whereas those against larval lysozyme recognize imaginal lysozyme. The data suggest that the genes coding for digestive enzymes (except for lysozyme) are different in larvae and imagoes.
