“…Four genes (CS_04235, CS_05017, CS_15183, CS_01854) related to digestion of proteins were upregulated in larvae developing under a long‐day photoperiod. This is congruent with previous reports suggesting that the photoperiod had significant effects on digestive enzyme activity (Espinosa‐Chaurand et al., 2017; Ramzanzadeh et al., 2016; Shan et al., 2008; Subala & Shivakumar, 2017). The functional link of many of these genes to diapause is not really clear.…”

The peach fruit moth (PFM), Carposina sasakii Matsumura, is a major phytophagous orchard pest widely distributed across Northeast Asia. Here, we report the chromosome‐level genome for the PFM, representing the first genome for the family Carposinidae, from the lepidopteran superfamily Copromorphoidea. The genome was assembled into 404.83 Mb sequences using PacBio long‐read and Illumina short‐read sequences, including 275 contigs, with a contig N50 length of 2.62 Mb. All contigs were assembled into 31 linkage groups assisted by the Hi‐C technique, including 30 autosomes and a Z chromosome. BUSCO analysis showed that 98.3% of genes were complete and 0.4% of genes were fragmented, while 1.3% of genes were missing in the assembled genome. In total, 21,697 protein‐coding genes were predicted, of which 84.80% were functionally annotated. Because of the importance of diapause triggered by photoperiod in PFM, five circadian genes in the PFM as well as in the other related species were annotated, and potential genes related to diapause and photoperiodic reaction were also identified from transcriptome sequencing. In addition, manual annotation of detoxification gene families was undertaken and showed a higher number of glutathione S‐transferase (GST) gene in PFM than in most other lepidopterans, in contrast to a lower number of uridine diphosphate (UDP)‐glycosyltransferase (UGT) gene, carboxyl/cholinesterases (CCE) gene and cytochrome P450 monooxygenase (P450) gene, suggesting different detoxication pathways in this moth. The high‐quality genome provides a resource for comparative evolutionary studies of this moth and its relatives within the context of radiations across Lepidoptera.

The peach fruit moth (PFM), Carposina sasakii Matsumura, is a major phytophagous orchard pest widely distributed across Northeast Asia. Here, we report the chromosome-level genome for the PFM, representing the first genome for the family Carposinidae, from the lepidopteran superfamily Copromorphoidea. The genome was assembled into 404.83 Mb sequences using PacBio long-read and Illumina short-read sequences, including 275 contigs, with a contig N50 length of 2.62 Mb. All contigs were assembled into 32 linkage groups assisted by the Hi-C technique, including 30 autosomes, a female specific W chromosome and a Z chromosome. BUSCO analysis showed that 98.2% genes were complete and 0.4% of genes were fragmented, while 1.4% of genes were missing in the assembled genome. In total, 23,218 protein-coding genes were predicted, of which 82.72% were functionally annotated. Because of the importance of diapause triggered by photoperiod in PFM, five circadian genes in the PFM as well as in the other related species were annotated, and potential genes related to diapause and photoperiodic reaction were also identified from transcriptome sequencing. In addition, manual annotation of detoxification gene families was undertaken and showed a higher number of ABC and GST genes in PFM than in most other lepidopterans, in contrast to a lower number of UGT genes, suggesting different detoxication pathways in this moth. The high-quality genome provides a resource for comparative evolutionary studies of this moth and its relatives within the context of radiations across Lepidoptera.

“…Thus, it is possible to affirm that for the adult crustaceans, in which the morphological development has already finished, the enzymes are mainly influenced by the diet, in addition to other physiological factors related to gonadal and reproductive maturation events. However, the circadian cycle, the photoperiod, and the molting cycle also exert effects on the activity of digestive enzymes, as demonstrated by Espinosa‐Chaurand, Vega‐Villasante, Carrillo‐Farnés, and Nolasco‐Soria () in juveniles of M. tenellum .…”

Development of enzymes during ontogeny of two freshwater Decapoda:Aegla uruguayana(Aeglidae) andMacrobrachium borellii(Palaemonidae)

The similarities or differences among species of the same family or among different families suggest a relationship with their feeding habits or a preference for the various types of food. The aim of this study was to identify the presence of digestive enzymes lipases, total protease, amylases and cellulose, and the effects of sex and size in these activities in two decapod freshwater crustaceans. Specimens of different sizes and sexes of Aegla uruguayana and Macrobrachium borellii were collected in the natural environment. In laboratory, enzymatic preparation consisted in homogenising the digestive gland in a buffer Tris‐HCl. The homogenates were centrifuged and the lipid layer was removed. Enzyme activities were determined using standard protocols. There were no statistically significant differences between sexes in any of the species under study. However, there were changes in the activity of amylases during the ontogeny of A. uruguayana, indicating that in juveniles the values of said activity are significantly higher than in the rest of the groups. M. borellii showed ontogenetic differences in total proteinase activity: organisms of range 2 (intermediate sizes) presented enzymatic activities much smaller than organisms of range 4 (larger sizes). The comparisons of enzymatic activities between both species yielded significant differences, being higher the values in the species A. uruguayana with respect to M. borellii. The results obtained in this work indicate that although both species are omnivorous and consume similar items, the activity of these digestive enzymes could be an evidence of different strategies of utilisation of the resource.
