Abstract
The Pear Psyllid, Cacopsylla bidens (Šulc, 1907), is here reported from the Department of Canelones, the major region of pear production in Uruguay. Previous records of C. pyricola (Foerster, 1848) from Uruguay are misidentifications of C. bidens. Information is provided on the taxonomy and biology of this species.
Highlights
Psyllids are phytophagous insects with a high degree of host specificity (Burckhardt et al 2014)
In South America, pear psyllids were probably introduced in the 20th century
As virtually nothing is known about the way of introduction of pear psyllids into South America and multiple introductions of different species are possible, a study was conducted to examine the identity of pear psyllids present in Uruguay
