Abstract

Carcina quercana is a polyphagous insect. In April 2018, larvae of C. quercana were observed for the first time in Majen Essef (north western Tunisia) on the strawberry tree (Arbutus unedo). To estimate the percentage of tree infestation, the number of infested trees among 40 trees found in an area of one hectare was counted. Branches of about 30 cm in length were cut and examined in the laboratory to determine the percentage of the infested leaves. On infested leaves, shelters were counted and the number of larvae by shelter was determined. The percentage of infested tree was 20% and that of infested leaves was 7.16%. In each leaf, we found between 1 and 3 shelters, in which only one larva host it. Larvae of C. quercana build their shelters of about 1.91 cm in length and 0.73 cm in width by means of silk.
