    Default Study Examines Cricket Nutrient Levels (3 species & several cricket diets)

    Hi All,

    Captive insect-eating reptiles and amphibians (and perhaps invertebrates) are often plagued by nutritional deficiencies. A highly-varied diet is a great way to ensure adequate nutrition, but most keepers have access to only a few feeder-insect species; gut-loading (providing nutritious diets to feeders) is helpful, but detailed studies are lacking. While touring several Japanese zoos a few years ago, I was intrigued by the number of cricket species being bred as herp food, and resolved to investigate the species and diets I saw in greater detail. A recent article in Zoo Biology (2011, V. 30), which provides insights into carotenoid supplementation in three different cricket species, has re-sparked my interest. I’ll summarize below. Also included are notes on other cricket/grasshopper species. Read article here: Crickets and Carotenoids - Study Examines Cricket Nutrient Levels | That Reptile Blog

    Comments and questions appreciated. As I do not place notices here each time I post a new article on That Reptile Blog, you may wish to check in periodically or subscribe; you can do so here That Reptile Blog. Please also check out my posts on Twitter Twitter.

    Thanks, Frank

    I noticed the part about the virus that is wiping out the population of house crickets. I read a small article about this and the Gryllus Assimilis are not the ones who are a threat, it is the crazy red heads that look very similar in size and shape. Gryllus Assimilis are darker in color when they reach maturity.
    It is illegal to ship crazy reds across state borders except within CA, since they are native to the area. I will see if I can find you that article I read.
    The pet store I bought my crickets from said they were not the Crazy reds, but if you dont mind me asking, could I take some pictures of the ones I have an get a positive ID? I know you are a herpetologist and not an entymologist, but I am sure you will know more than I do.
    here is the website: Ghann's Cricket Farm :: Gryllus Info
