Like their hosts, they have an enzyme which converts the glucosinolates into toxic mustard oils. A research team at the Max Planck Institute for Chemical Ecology in Jena, Germany, has now found that these glucosinolates are present in all life stages of the horseradish flea beetle; however, the enzyme required to convert these into toxic substances is not always active. Although larvae are able to successfully fend off attack from a predator, such as the harlequin ladybird, pupae are predated because they lack enzyme activity. These findings have been published in Functional Ecology, in February 2020.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-03-horseradish-flea-beetles-deter-predators.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Whether horseradish flea beetles deter predators depends on their food plant and their life stage<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Horseradish flea beetles use plant defense compounds, so-called glucosinolates, from their host food plants for their own defense.
