There are three species of beetles of the Curculionidae family (Scolytinae) that are very similar to each other. T.piniperda and T.minor are found in cold climate zones, while T.destruens is found in coastal areas. The main difference is that, while the adults of T.piniperda and T.minor are inactive during winter time, the adults of T.destruens remain active from September to April, period during which they lay eggs on the trunks and also move to the terminal shoots to feed. Adults measure 4-5 mm and larvae can reach up to 6 mm.
For effective control, carry out treatments with plant endotherapy (ENDOterapia Vegetal®) when the insect is feeding on the small branches, and before it attacks the trunk. If the trunk is affected, the treatment may not be very effective, depending on the amount of conductive vessel elements that have collapsed due to the holes made by the insect.
