Cherry fruit beetle

The cherry fruit beetle (Rhynchites versicolor) is a destructive pest belonging to the Attelabidae family within the order Coleoptera. This small weevil is widely recognized by pomologists as a significant threat to stone fruit orchards across temperate regions.

The primary host plants for this species include cherries, sour cherries, plums, and apricots. The pest is particularly aggressive during the initial stages of fruit development, posing a serious risk to the entire potential harvest of the orchard if left unmanaged.

The biological development of this beetle is strictly synchronized with the phenology of fruit trees. Adults overwinter in the soil and emerge in early spring when temperatures rise. They initially feed on buds and blossoms, progressively moving to tender leaves and developing young fruit as the season advances.

Damage occurs when the female beetle bores into a young fruit to deposit an egg and subsequently severs the fruit stem. This action causes the fruit to wither and fall prematurely. Larvae then feed on the decaying fruit material, which significantly lowers fruit quality and overall yield quantity.

• Regular collection and proper disposal of fallen fruit to break the life cycle.
• Autumn cultivation of the soil under tree canopies to destroy overwintering larvae.
• Early morning manual collection by shaking trees over protective netting.
• Application of targeted insecticides during the pre-blossom and post-blossom periods.
