Cholesterol turnover in the American cockroach, Periplaneta americana (L.)

We provide an updated checklist of Orthoptera and their allies for each Maritime province of Canada with details for 21 new species records. Drumming Katydid (Meconema thalassinum), recorded from Nova Scotia (NS) and Prince Edward Island (PEI), and Sprinkled Grasshopper (Chloealtis conspersa), recorded from New Brunswick (NB) are reported for the first time from the Maritimes as a whole. We report range extensions in the Maritime region for Australian Cockroach (Periplaneta australasiae; NB), Treetop Bush Katydid (Scudderia fasciata; NS), Short-legged Camel Cricket (Ceuthophilus brevipes; PEI), Spotted Camel Cricket (Ceuthophilus maculatus; PEI), Roesel’s Shield-backed Katydid (Roeseliana roesellii; NS), and Black-horned Tree Cricket (Oecanthus nigricornis; PEI). Short-winged Mole Cricket (Neoscapteriscus abbreviatus; NB) and European Mole Cricket (Gryllotalpa gryllotalpa; NS) are reported as adventives (non-native species that are believed to be not yet established), new to Canada from the Maritimes. Other new records for species not known to be established are Lined Earwig (Doru taeniatum; NS), Australian Cockroach (Periplaneta australasiae; PEI), American Cockroach (Periplaneta americana; NB), Brown Cockroach (Periplaneta brunnea; PEI), Smooth Cockroach (Nyctibora laevigata; NB), West Indian Leaf Cockroach (Blaberus discoidalis; NB), an unidentified Parcoblatta species (NB), Brown-banded Cockroach (Supella longipalpa; PEI), Praying Mantis (Mantis religiosa; NB), and American Bird Grasshopper (Schistocerca americana; NS).

Dpph Radical Scavenging

Among different insects, the American cockroach (Periplaneta americana) has been bred in industrial scale successfully as a potential resource of protein, lipid, and antibacterial peptide. However, the application of its chitosan has not been studied widely, which has hindered the sufficient utilization of P. americana. In this paper, the chitosan from P. americana was separated, characterized, and processed into film (PaCSF) to examine its potential of being applied in food packaging. As the results of different characterizations showed, PaCSF was similar to shrimp chitosan film (SCSF). However, concerning the performances relating to food packaging, the two chitosan films were different. PaCSF contained more water (42.82%) than SCSF did, resulting in its larger thickness (0.08 mm). PaCSF could resist UV light more effectively than SCSF did. Concerning antioxidant activity, the DPPH radical scavenging ability of PaCSF increased linearly with time passing, reaching 72.46% after 8 h, which was better than that of SCSF. The antibacterial activity assay exhibited that PaCSF resisted the growth of Serratia marcescens and Escherichia coli more effectively than SCSF did. The results implied that P. americana chitosan could be a potential raw material for food packaging, providing a new way to develop P. americana.
