Evaluation of soybean cultivars Glycine max (L.) Merr. susceptibilityto damage caused by Arion vulgaris Moquin Tandon, Arion rufus (Linnaeus)and Deroceras reticulatum (O.F. Muller)

摘要

Slugs cause serious damage locally to soybean cultivations, particularly at seedling emergence and at the development of first leaves. Susceptibility of soybean plants to slugs may vary due to varying eating preferences of these pests and specific cultivar characteristics. In order to determine the extent of damage caused by Arion vulgaris, Arion rufus and Deroceras reticulatum, we performed laboratory tests, in which young plants of ten soya cultivars were exposed to the feeding of slugs. It was concluded that soybean plants differ in their susceptibilities to damage depending on the cultivar and slug species. The slugs of the Arion genus caused the least damage to Simona and Aldana cultivars. The slugs of the genus Deroceras did not show food preferences in relation to selected cultivars of soybean.
