“…This concurs with monitoring data that have shown losses to waterbodies within 1–4 days of application to land (Calumpang et al . ; Lazartigues et al ., ). Degradation in soil varies depending on conditions and reported half‐life ranges between 3.17 and 223 days (IPCS ; PAN ; PPDB ; Ma et al .…”

“…Pomacea canaliculata is a gastropod Bianchini et al from the family Ampullariidae, popularly known as golden apple snail. The uncontrolled spread of these gastropods has increased the demand for preventive and control measures through products that are non-toxic to other non-target organisms and the environment, as synthetic products used for this purpose have high residual effects (CALUMPANG et al, 1995). Products extracted from plants are promising alternatives because they are biodegradable and from renewable sources; they also have fewer adverse effects on the ecosystem.…”

Relaxing effect of eugenol and essential oils in Pomacea canaliculata

et al. 2017

This study evaluated the potential relaxing and/or molluscicidal effects of eugenol and essential oils of Origanum majorana, Ocimum americanum, Hesperozygis ringens, and Piper gaudichaudianum in the gastropod Pomacea canaliculata. Compounds were tested at concentrations of 100, 250, 500, and 750µL L-1 to evaluate the relaxing effects. In the second experiment, animals were exposed to 10, 25, and 50µL L-1 of essential oils of H. ringens and P. gaudichaudianum for a period of 24h for the evaluation of molluscicidal effects. Eugenol and essential oils of O. majorana and O. americanum showed relaxing effects at ≥250µL L-1, but the essential oils of H. ringens and P. gaudichaudianum did not promote relaxing or molluscicidal effects within the times and concentrations studied. Therefore, only eugenol and the essential oils of O. majorana and O. americanum can be used for relaxation purposes in P. canaliculata.

“…observ.). Some studies using chemical applications have succeeded in reducing snail densities to levels that were considered low enough to minimize damage, but success has come with high mortality of non-target organisms (Calumpang et al 1995, de la Cruz et al 2000, Maini and Morallo-Rejesus 1993. Chemical treatment to control apple snails has proven most effective when the chemical directly contacts snails (de la Cruz and Joshi 2001).…”

“…Various methods (e.g., chemical, biocontrol, mechanical, integrated) have been used in attempts to control the spread and impacts of nonindigenous apple snails, each with varying degrees of success and most with a focus on crop protection (Calumpang et al 1995, Estebenet and Cazzaniga 1990, Halwart et al 1998, Litsinger and Estano 1993, Wada 2004, Yusa et al 2006). The St. Johns River Water Management District attempted chemical eradication of nonindigenous apple snails using copper sulfate (CuSO 4 ) in a small portion (14.57 ha) of Newnans Lake (2700 ha, Alachua County, FL).…”
