where it has caused widespread damage. One cause of the explosive
spread of the weevil is human. Demand for new trees has created the
need to re-locate infested trees from contaminated to otherwise
uninfected locales. Additionally, as the Red Palm Weevil has
particularly strong wings, they are capable of flying considerable

Silves, particularly those along the riverbank from the traffic
lights at the bridge to the Palace of Justice roundabut heading
