The article presents an assessment of the threat posed by the pest to traditional commodity production of pineapple strawberries in the open ground commodity fruiting in the vegetation of 2020.

Accounting plots (test sites) were 2×2 m in size; accounting area № 1 was the control area. Using bio-molluscicide of Ukrainian production – Ulicide; accounting area № 2 was open to the pest.

Despite almost the same potential of biological yield of both accounting plots, the accounting plot № 2 managed to gether 27 %, almost 4 part of the expected yield. The quality of the crop was low, as the fruits were contaminated with the mucus of the pest, due to micro-damage by the pest they were more quickly affected by fungal infections: powdery mildew and gray rot.

Arion lusitanicus s. l. has a high adaptive potential. Agrotechnical measures for the care of fruiting pineapple strawberries, in particular, loosening the soil in rows contribute to the easy deepening of the pest in the root system of the plant, and a powerful leaf apparatus of plants safely comfortable transfer of hot hours of the day. Calculation of the pest showed its significant population, on average, 11 specimen/m2.

Thus, the uncontrolled spread of the pest in the short term will lead to the impossibility of growing pineapple strawberries in the open ground. The usual favorite fruit will be either dangerous due to the ban on the irresponsible use of toxic drugs on fruit-bearing plantations (active substance – metaldehyde) to control Arion lusitanicus s.l. or inaccessible due to the use of expensive alternative protection measures, indoor technologies. Shortly there will be quarantine measures by the relevant authorities, and also development and implementation of effective pest control measures.
