MetadataShow full item record
Population density of slugs (Vaginulus plebeius) and damage to common bean plants (Phaseolus vulgaris).
Direct nighttime observations and baited pit fall traps were used to determine population densities of active slugs, Vaginulus plebeius at various distances from a source of infestation. These observations were related to seedling damage and yield of dry beans. Each active sluglin2 Might, resulted in plant stand reduction of 20% and yield reduction of 16%. For each slug captured in the pit fall traps per night, the plant stand was reduced by 14% and yield by 11% . Tentative economic injury levels of 0.25 active slugslm2 or 0.4 slugsitrapinight were calculated. In the presence of bean seedlings, slugs move only short distances.
