The map (fig. 4) shows the distribution of this pest in the Canal Zoneand adjoining parts of the Republic of Panama. The hosts on which Aleurocanihus woglumihsLS been found in variousparts of the Old and New Worlds will be found under the heading,Food plants, page 14. SPREAD OF THE INSECT IN THE NEW WORLD. Ashby (3) says that Aleurocanthus woglumi was probably broughthere [Jamaica] on mango cuttings from India within the last 20years. Morrison, after his investigation of conditions in Jamaica,believes that the pest has been introduced certainly within 10 yearsor even as late as 1910. There is no question that the insect wasfirst introduced into Jamaica from India either on mango or someother host, and that from this focus in the New World it has spreadto Nassau, New Providence, Bahama, the Guantanamo and Santiagode Cuba regions
