“…We observed that the alpha amylase activity was reduced in larvae reared on raisins and dates, but this activity was detectable as the main isoenzyme from larvae raised on dates (rich in glucose). This was also reported by Inomata and Yamazaki (2000) working on Drosophila reared on various sources of carbohydrates, and Bouayad et al (2008) working on P. interpunctella reared on different food diets. Inomata et al (1995) studied intraspecific variation of alpha-amylase activity in D. melanogaster and D. immigrans, and suggested that glucose repression was conserved among species at both stages while starch induction was mainly observed in larvae, although the degree of the response depended on species.…”

Plodia interpunctella (Hübner 1813) (Lepidoptera: Pyralidae) is a cosmopolitan species known to infest a wide range of dried plant materials, including legumes and cereals. In this study, enzyme activity and expression of alphaamylase gene in larval P. interpunctella grown on four different nutrition regimes was studied. The different nutrition regimes caused differential change in expression of alpha-amylase gene. Compared with the control (artificial diet), the walnut regime caused a 10.8% increase in expression of the alpha-amylase gene, whereas 79.3, 52.5, and 7.5% decreases were observed in the larvae grown on dates, raisins and oleaster respectively. The results also showed that glucose repression varied among larvae feeding on different food diets. The results revealed that expression of the alpha-amylase coding gene was significantly reduced in the larvae grown on date and raisin containing high amounts of glucose. A biochemical assay indicated overlapping of alpha-amylase activity and expression. Complexity in expression of amylase genes suggests the existence of a negative feedback mechanism in the insect larvae. Different parameters can affect gene expression and activation, which may explain the results presented here.Résumé. Effet de quatre régimes alimentaires différents sur l'expression du gène de l'alpha-amylase chez la Teigne des fruits secs, Plodia interpunctella. Plodia interpunctella (Hübner 1813) (Lepidoptera : Pyralidae) est une espèce cosmopolite connues pour infester une large gamme de matières végétales séchées, y compris les légumineuses et les céréales. Dans cette étude, l'activité enzymatique et l'expression du gène de l'alpha-amylase dans des larves de P. interpunctella élevées sur quatre régimes alimentaires différents ont été étudiées. Ces différents régimes ont causé un changement important dans l'expression du gène de l'alpha-amylase. Comparativement avec le régime témoin (milieu artificiel), le régime à base de noix a induit une augmentation de 10,8% dans l'expression du gène, tandis que 79,3%, 52,5% et 7,5% de baisse ont été obtenus chez les larves qui ont eu un régime, respectivement, à base de dates, de raisins secs et d'olives. Les résultats ont montré que la répression du glucose variait en fonction du régime alimentaire des larves. Ils ont également révélé que l'expression de gène codant pour l'alpha-amylase a été significativement réduite chez les larves se nourrissant de dates et de raisins secs contenant une grande quantité de glucose. Des tests biochimiques ont indiqué un chevauchement entre l'activité de l'alpha-amylase et son expression. La complexité dans l'expression des gènes de l'amylase suggère l'existence d'un mécanisme de rétroaction négative chez les larves de cet insecte. Différents paramètres peuvent influencer l'expression et l'activation des gènes codant pour l'alpha-amylase et permettent d'expliquer les résultats obtenus.

“…It is conceivable that the addition of amylase to the food increases its glucose content, which in turn may have caused the pupation delay. Consistent with this hypothesis, glucose-enriched food delays pupation in Plodia interpunctella (Bouayad et al 2008). Bouayad reported that amylase activity was reduced when the larvae were grown in glucose-enriched food.…”

Drosophila melanogaster larvae control amylase secretion according to the hardness of food

Drosophila melanogaster larvae excrete amylase and perform external digestion of their food. In this study, to investigate whether their external digestion ability varies in response to changes in the external environment, we measured the relative amount of amylase excreted by larvae using a new method: the iodine starch agar method (ISAM). Analysis using this method revealed that the amount of amylase excreted by larvae increased in accordance with the increase in the agar concentration. In addition, we investigated the effect on the larval growth rate of adding amylase to the diet. Pupation occurred 24 h later in food containing 1% amylase than in food containing no amylase. These results suggest that the larvae adjust their amylase excretion in response to changes in the external environment, and that its level has a marked influence on the larval growth rate.

25Helicoverpa armigera is an important pest of crops worldwide, and several studies have 26 focused on the development of artificial diets for this species. However, studies evaluating the 27 insect´s performance at nutritionally different diets are scarce. Larval development is dependent on 28 the ratio of protein and carbohydrates. The aim of this study was to evaluate the biology and to 29 compare the consumption and use of food of H. armigera larvae on diets with different protein 30 levels. The nutritional index, the relative consumption rate, the relative metabolic rate, the relative 31 growth rate, and the apparent digestibility were higher in the diet with added protein. On the other 32 hand, the conversion efficiency of digested food was lower, resulting in a higher metabolic cost. In
