Life cycle and field abundance of the snail Succinea costaricana (Stylommatophora: Succineidae), a tropical agricultural pest

The neotropical terrestrial snail Succinea costaricana has become a quarantenary pest in ornamental plants (Dracaena marginata, Dracaenaceae). Specimens were collected in GuápiJes, Limón, Costa Rica, where they reached a density of 282900 individualslha. In the field, reproduction is continuous (as...

The following are mean values: 7 eggs/cluster; lA mm egg diameter; 0. 25 and 0. 84 mm embryo and newborn shell length, respectively; 11 days (embryo development at 24 oC); 16 mm/min locomotion speed (young). The animals can reproduce at 12 weeks (lifespan: 44 weeks). The pigmentation pattern is defined after seven weeks.
