Kelly's Thrips

Frankliniella kelliae is a species of small insects from the order Thysanoptera, family Thripidae. This species is a specialized pest that poses a potential threat to a wide range of agricultural and ornamental crops, particularly in greenhouse and protected soil conditions.

The pest affects various types of plants, including vegetables, ornamental flowers, and berry crops. Primary damage is caused by both adults and larvae, which feed on the cell sap of plant tissues, disrupting normal physiological processes and reducing the productivity of cultivated plants.

The biology of Frankliniella kelliae is closely linked to climatic conditions. Its life cycle consists of several stages: egg, two larval stages, propupa, pupa, and adult. The insect has a high reproductive rate, allowing populations to increase rapidly under favorable temperature conditions and adequate humidity.

The nature of the damage manifests as discolored spots, streaks, and deformation of leaf blades, buds, and flowers. Necrosis often occurs at the sites of tissue punctures, and severe infestations lead to massive shedding of flowers and ovaries. The pest can also act as a vector for dangerous plant viruses.

The system of protective measures includes the use of agrotechnical methods (crop rotation, destruction of reservoir weeds) and the application of chemical control agents. Regular monitoring using sticky traps is recommended, as well as the use of systemic insecticides approved for use in the corresponding agricultural sector.
