| dc.description.abstract | Survey of five plant nurseries at different locations viz. New Indian nursery and Gulrej nursery at Dhuri, Bhagwaan and Golden nursery at Malerkotla and Plant nursery PAU, Ludhiana for gastropod population revealed that one snail, Macrochlamys indica and one slug, Filicaulis alte Ferussac with three colour forms viz. black slug with yellow mid-dorsal streak, brown slug with black spots, black slug were infesting the plant nurseries. Slugs and snails preferred soil with low bulk density, high porosity and high moisture. Impact of three treatments on gastropod (snails and slugs) trapping was in following order- Damp conditions > Beer traps > Spots with Spinach. Snails and slugs excavated holes within leaves of ornamental plant saplings. More damage was observed during the months of June, July and October when the population density of snails and slugs active at soil surface was more. Hence, more emphasis should be laid down on gastropod control during the months of June, July and October to prevent the damage to ornamental plant saplings. Laboratory feeding tests revealed that out of the different concentrations of crude latex of different plants viz., Euphorbia splendens, Calotropis procera, Ficus bengalensis and Ficus elastica, bait with 2 per cent crude latex of E. splendens proved to be most effective bait resulting in 36.7 per cent mortality (F. alte, black slug with yellow mid-dorsal streak) with highest consumption among all the different concentrations of all the four plants. Thus, E. splendens latex acts not only as molluscicide but as attractant also. | en_US |
