Ecology

Sarasinula plebeia: This is a serious pest of agriculture in Central America. In South America this slug consumes legume pods and flowers, as well as the foliage of beans, sweet potato, cabbage, Cucurbita sp., tomato, coffee, weedy species in the genus Borreria, and the fruit of papaya. In many cases, this pest species has been known to eat young plants to the ground on farms. Plant nurseries that grow tree species like mahogany and red cedar have also been affected by this species. This slug can transmit the nematode Angiostrongylus costaricensis, which is pathogenic to humans.

Sarasinula plebeia can bury itself in the soil to a depth of up to 100 cm in order to protect itself from desiccation during the dry season. In Texas it has shown the potential to survive sub-freezing temperatures. This hermaphroditic slugs can reproduce by self-fertilization. It can lay up to 80 eggs per clutch. The oval, translucent eggs have an incubation time of 20-24 days at 27 degrees Celsius. Adulthood can be attained in 2-5 months and the adults can live for more than a year.

S. marginata: This species has been reported to feed on dasheen (Colocasia esculenta) in the field. This slug is a minor pest of agriculture in Dominica. The genitalia may be used to distinguish this species from Sarasinula plebeia and S. dubia.
