Abstract
Lac is the resinous encrustation secreted by the scale-insect, Laccifer (Tachardia) lacca, Kerr (Coccidae). Research with a view to the improvement in quality and quantity of this secretion consists therefore in a study of the Coccid itself and the hosts on which it lives, and the relationship between the insect and its hosts. It also entails an investigation of the insect friends and enemies of the Coccid and of its hosts.
