Molluscicidal activity of the aqueous extracts from Solanum mammosum L., Sapindus saponaria L. and Jatropha curcas L. against Pomacea canaliculata

Abstract

Biomolluscicides development is of great interest in pest management to avoid the effects on the environment caused by synthetic molluscicides. The Species: Solanum mammosum L., Sapindus saponaria L. and Jatropha curcas L. have demonstrated molluscicidal properties against Pomacea canaliculata. This study was carried with mixtures of aqueous extracts of these plants in order to check for a synergistic effect between them. Extracts obtained from each species were evaporated and lyophilized. By using a simplex centroid design were obtained ten mixes for testing. All of them were diluted to 500ppm and tested on adult snails for 24 hours of exposure followed by 24 hours of recovery on tab water. Those mixes that showed the best results of mortality were chosen to determine the median lethal dose. The formulations S. saponaria (100%) and S. mammosum -S. saponaria (50%-50%) showed the best results of mortality with LD50 values of 24.04 ppm and 17.78 ppm respectively, with no significant differences between them (p> 0.05). These results showed that a synergistic effect is not produced in the activity of these plants when the extracts mixture was performed.

Effects of dietary supplementation of golden apple snail (Pomacea canaliculata) egg on survival, pigmentation and antioxidant activity of Blood parrot

“…This species has invaded several European, North American, and Asian countries and damages rice and aquatic organisms (Accorsi et al 2014 ; Horgan et al 2014 ; Karraker and Dudgeon 2014 ). Given the adverse effect of this species, physical, chemical, and biological control techniques have been established; such methods include crop rotation (Wada et al 2004 ), use of molluscicides (Cruz et al 2000 ; Quijano et al 2014 ), and use of predators (Su Sin 2006 ; Ip et al 2014 ; Yusa et al 2006 ). As an abundant aquatic living resource, utilization of egg of golden apple snails has been rarely reported.…”

Development and Evaluation of Poly Herbal Molluscicidal Extracts for Control of Apple Snail (Pomacea maculata)

“…The ethyl acetate soluble fraction of Aglaia duperreana was effective against GAS [26]. In rice field conditions, the molluscicidal efficacy of chemically modified quinoa (Chenopodium quinoa) saponins [27], methanol extract of Camellia oleifera seed meal [28], and Sapindus saponaria extract [29] were tested against GAS. The application of tobacco waste in field trials proved its efficacy with 100% mortality of GAS [30].…”

Field Evaluation of Plants Molluscicide against Pomacea canaliculata

“…Sapindus saponaria L. molluscicidal activity is attributed to the presence of saponins (Pinto et al, 1944), substances that interact with sterols present in cell walls of gills mollusks, causing cell rupture (Karabaliev et al, 2003;San Matins et al, 2009) (WHO, 1983b). (Quijano et al, 2014). Discrepancy between laboratory and field assays may arise because the presence of weed, mud and lower content of dissolved oxygen in the water, factors that reduced the molluscicidal activity of both formulations (Adewunmi and Marquis, 1987;San Martín et al, 2009).…”

“…Solanum mammosum L. and Sapindus saponaria L. are natural molluscicide and their combined effect against Pomacea canaliculata has been evaluated under laboratory conditions by Quijano et al (2014); those authors demonstrated that there was not a synergism effect in the combination Sapindus saponaria L. and Solanum mammosum L. (50:50, w/w). 1 (ISSG, www.issg.org/database).…”
