Paramphistomosis caused by Calicophoron daubneyi and fasciolosis Fasciola hepatica are common parasitic diseases of livestock animals. Transmission the depends on presence intermediate hosts, i.e. freshwater gastropods such as lymnaeids. We carried out a 2-year-long study dynamics snail population acting host for these parasites, considering structure in terms size/age infection status. In addition, we determined kinetics trematode egg excretion grazing cows. Generalized Additive Models...
Abstract The Harpalini species Harpalus rufipes , as many other generalist carabids, consume a wide variety of prey and it is known to feed on pest slugs such the grey field slug Deroceras reticulatum but quantitative data about predatory activity H. are very scarce. In laboratory experiments, we assessed capability male kill eggs different‐sized D. in either absence or presence alternative live (dipteran larvae aphids). We also investigated preference for hatchlings choice experiment....
Invasive snails and slugs are among the most damaging pests of vegetables, fruits, ornamentals, grains, forage throughout world. Current control strategies focused almost exclusively on molluscicides, which ineffective under some conditions, can have serious nontarget effects. A major aim this study was to develop a generic high-throughput bioassay method for use in identifying attractants terrestrial gastropods, with overall goal developing attractant-based methods pest gastropods. Here, we...
Surface traps are recommended to monitor slugs in arable crops, but pastureland differs from land many respects and these may affect the performance of sampling methods. Here, we report on non-baited mat refuge traps, permanently placed at same position over more than 2 years four established pastures, for assessment slug numbers biomass, comparison with soil flooding 3 days. Despite high availability alternative shelters provided by vegetation, a great were captured study period wide range...
Invasive slugs and snails are among the most damaging pests of agriculture in temperate tropical regions world. Control options, however, limited there is a heavy reliance on chemical molluscicides variable efficacy. There an ongoing need to improve management methods. Here, we show that simple fermenting bread dough formulation (flour, water, yeast) was effective attracting pest mollusk species laboratory tests, multiple replicated field trials Hawaii, Oregon, Montana. The attracted...
Attraction of the invasive snail Xerolenta obvia (Menke, 1828) to chopped cucumber and a previously identified attractant based on steam distillate dry cat food was assessed with an established field population in Montana. Snails were significantly more attracted than bottled water (control), using both traps direct observations attractants deployed Petri dishes. The also snails distillate. These results suggest that could constitute cheap simple lure for this other mollusk species. In...
