Trampa para determinar la densidad poblacional de la babosa, Vaginulus plebeius, plaga de frijol común

Abstract

Pit fall traps baited with a mixture of bran, molasses, beer and carbaryl are accurate indicators of the population density of active slugs, Vaginulus plebeius. For each active slug encountered in direct nighttime counts, 7 were trapped. The traps are simple and inexpensive to construct and use. They should be useful for dry bean farmers of Central America who must make chemical control decisions.
