Article Synopsis
- The study investigates how a specialized leaf beetle shifted from feeding on willow to birch, focusing on its chemosensory genes that influence host selection.
- Researchers identified 114 chemosensory candidate genes in the beetle, finding significant differences in gene expression related to host plant preference.
- The findings suggest that specific olfactory and gustatory receptors evolved, aiding the beetle in detecting new phytochemicals from birch, leading to its adaptation and specialization on this novel host plant.
Covering up to September 2016This review reports on natural compounds that derive from the isoxazolinone ring as well as the 3-nitropropanoic acid (3-NPA) moiety. These structural elements occur in compounds that have been identified in plants, insects, bacteria and fungi. In particular, plants belonging to the family of legumes produce such compounds.

Using light microscopy and TEM, the reflector was located underneath the macrofiber endocuticle just above the epidermis. The reflector is a multilayer comprising up to 50 bilayers alternating high and low density layers parallel to the surface of the cuticle.

When disturbed, they transiently expose volatile deterrents in large droplets from nine pairs of defensive glands on their back. Here, we report on an additional line of defense consisting of the non-volatile isoxazolin-5-one glucoside and its 3-nitropropanoyl ester in the larval hemolymph.
