cornicle การใช้

There also is evidence of cornicle wax attracting aphid predators in some cases.
Like aphids, phylloxera feed on the roots, leaves, and shoots of grape plants, but unlike aphids, do not produce honeydew or cornicle secretions.
Most aphids have a pair of cornicles ( or " siphunculi " ), abdominal tubes through which they exude droplets of a quick-hardening defensive fluid containing triacylglycerols, called cornicle wax.
The "'cornicle "'( or "'siphuncule "') is one of a pair of small upright backward-pointing tubes found on the dorsal side of the last segment of the bodies of aphids.
