ABSTRACT

Malformations in animals have long been known. In gastropod, natural and induced malformations are mentioned in different systems and in ocular tentacles, mainly linked to cases of parasitism and exposure to pollutants (molluscicides and chemicals). In this study we present a new malformation not documented in the ocular tentacles of slug Deroceras reticulatum that could be due to the action of pesticides. This malformation in D. reticulatum is the first malformation to be mentioned for South America in nursery gardens.(AU)

ABSTRACT

This research reports the terrestrial slug Meghimatium pictum (Stoliczka, 1873) (Stylommathophora: Philomycidae) as an agricultural pest for the first time in Southern Brazil vineyards. The species was found in densities exceeding 20 slugs.m-2 in Vitis labrusca L. vineyards at six municipalities of the Southern Brazil's viticulture region. It causes damage a loss by leaving residual mucus on grapes and by consuming grapes already perforated by other organisms, such as insects or birds, or mechanically damaged by in situ compression. The effectiveness of iron phosphate and metaldehyde baits on M. pictum was evaluated in laboratory experiments. Iron phosphate bait was more effective in controlling M. pictum (70%) than metaldehyde bait (15%).


O presente trabalho relata pela primeira vez a lesma terrestre Meghimatium pictum (Stoliczka, 1873) (Stylommathophora: Philomycidae) como uma praga agrícola causando danos em vinhedos no Sul do Brasil. Esta espécie foi encontrada em densidades superiores a 20 lesmas.m-2 danificando uvas da espécie Vitis labrusca L. em seis municípios da região vitícola do Sul do Brasil. O impacto econômico causado por M. pictum está associado ao movimento dos espécimes no dossel da videira e nas uvas, provocando a contaminação residual por muco e o consumo de uvas já perfuradas por outros organismos, tais como insetos ou aves, ou mecanicamente danificadas pela compressão in situ. A eficácia das iscas a base de fosfato de ferro e metaldeído sobre M. pictum também foi avaliada em condições de laboratório. A isca a base de fosfato de ferro foi mais eficiente no controle de M. pictum (70%) do que a isca a base de metaldeído (15%).
