MONITORING THE ATTACK PRODUCED BY THE SPECIES CAMERARIA OHRIDELLA DESCHKA-DIMIĆ IN CRAIOVA AREA

STAN RALUCA, MITREA I

Abstract


Cameraria ohridella Deschka-Dimić is an invasive, monophagous species, extremely dangerous for the ornamental chestnut trees.

Following the observations we made, it can be concluded that the southern exhibition is preferred by the larvae of the species Cameraria ohridella Deschka-Dimić, so for observation made in July 2019 the values were 3.6 mines/leaf and 8.7 mines/leaf in August, and this year it was 3.9 mines/leaf for July, reaching 8.9 mines/leaf in August, an indicator that increased rapidly over the time between the two observations and  followed by the leaves with eastern exposure and western.

We also noticed that the lowest values of the average number of mines/leaf/foliole were reached on the leaves with northern exposure.
