The pine weevil (Hylobius abietis) is one of the most damaging pests in European forestry, particularly in conifer reforestation zones. First documented in the 18th century, its presence has steadily grown with large-scale logging and tree planting operations. After clear-cutting, pine weevils are drawn to freshly planted young trees, where they feed on the bark and stem, often killing the saplings before they can establish. Over the decades, this pest has caused major economic and ecological setbacks across Scandinavia, Central Europe, and parts of the UK.

RPW damage affects the income of around 123,000 small farms in Saudi Arabia. Annual losses in date production range between US$ 6 and 17 million and the cost of removal of infested palms in the Gulf region is estimated to be between US$ 5 and 25 million at an infestation rate of 1% and 5% palm tree, respectively.

The agave snout weevil (Scyphophorus acupunctatus), also known as the sisal weevil, feeds on many species of agave and can be especially damaging to the larger species such as century plant (Agave americana) and blue agave (Agave tequilana).

More than 900 species of insect-pests attack the coconut palm, among those are the rhinoceros beetle, red palm weevil and coconut mite. Currently, farmers are solely dependant on chemical sprays which are destroying the natural enemies the insect- pest would have.
