"Apraclonidine, a selective alpha-2-agonist, was developed to lower intraocular pressure and minimize the systemic side effects associated with the use of its parent drug, clonidine," write Patrick Watts, MBBS, MS, from the University Hospital of Wales in Cardiff, United Kingdom, and colleagues."An investigation of the site of action of apraclonidine incidentally uncovered a reversal of anisocoria in patients with absent sympathetic innervation of one pupil due to its alpha-1-effect on a pupil with denervation supersensitivity.... The easy availability of apraclonidine, its mild alpha-1-agonist activity, and its hitherto benign safety profile has encouraged its use as a first-line drug in the diagnosis of oculosympathetic paralysis."

Result shows that the Apriona germari adult insect prefer to eat Broussonetia papyrfera and reject to eat other tree species which result in difference in natural life and fecundity. Total sugar and dissolvable protein content in the bark is not the cause of rejection. Difference of dissolvable sugar and amino acid may be the reason of preference while difference of dissolvable phenolics and tannin content may explain the rejection.
