Abstrak: Deroceras laeve and Meghimatium bilineatum are slugs which are pest, that attacks the vegetables crop. The aims of this research is to study the density and distribution (pattern, feeding activity, and size) of D. laeve and M. bilineatum on 10 types of vegetables at Agropolitan, Cipanas. Sampling was conducted by quadrat method randomly. The highest density of D. laeve was 13.33 ind/m2 on Allium fistulotum and the lowest was 4 ind/m2 on Cripsum frutescens. The highest density of M. bilineatum was 6.22 ind/m2 on Solanum lycopersicum whereas the lowest was 0.56 ind/m2 on Daucus carota. Distribution Pattern of D.laeve and M. bilineatum is group. Distribution of D. laeve of small size (< 1.5 cm), medium (1.5−2.5 cm), and large (> 2.5 cm) were found in 9 different types of vegetables. Distribution of M. bilineatum of small size (< 2 cm) are rare, while the medium size (2−4 cm) and large (> 4 cm) were found in the 4 types of vegetables.

Abstrak: Meghimatium bilineatum and Deroceras laeve are gastropod without shells. These animals live as pests in horticultural commodities (such as Allium fistulotum). This study aims to determine the behavioural activities of the M. bilineatum and D. laeve on Allium fistulotum in Agropolitan Agricultural Regions, Cipanas. The observed behavioural activities are their emerging, locomotion, feeding, returning to their hideout and mating. Observations were carried out from 18:00 in the twilight until 6:00 in the morning for 20 days. The results of this study indicated that the M. bilineatum’s behavioural emerging activity was peaked at 19:00, locomotion activity peaked at 19:00 and 02:00, feeding activity peaked at 23:00 pm, and returning to their hideout peaked at 03:00, while mating activity was not too often found. For D. laeve’s emerging activity, locomotion activity, feeding activity, returning to their hideout peaked at 18:00, at 18:00 and 04:00, at 22:00, and respectively, at 05.00.
