The Efficacy of Wild Yam ( Dioscorea villosa ) Extract as Golden Apple Snail ( Pomacea canaliculata ) Molluscicide
Abstract
This study was conducted to compare the effectiveness of 150 mL wild yam (Dioscorea villosa) extract as golden apple snail (Pomacea canaliculata) molluscicide on different water level of mini-pond. This experimented study made use of One Way Analysis of Variance (ANOVA) to determine the significant difference on the mortality rate of golden apple snail when treated with 150 mL wild yam extracts on different water level mini-pond such that treatment A is 1cm water level treatment B is 2 cm water-level, treatment C is 3cm water level mini-pond. Based on the result, treatment A with 150 mL wild yam extract 1cm water level mini-pond produced the highest mortality rate golden apple snail, followed by treatment B with 150 mL wild yam extract on 2 cm water level and lastly, treatment C with 150 mL wild yam extract on 3 cm water level mini-pond.
Moreover, the result of the reaction showed that the mortality rate of golden apple snail differ significantly from each other when treated with 150 ml wild yam extract on different water level mini-pond. So, the result of the study showed that the wild yam extract is an effective golden apple snail molluscicide.
Furthermore, the researchers recommend that before the application of wild yam extract, the water level of the pond/field must not exceed to 1cm. It is also recommended that similar studies must be conducted using wild yam extract for other types

    What's The Trouble, By Jerome Groopman

    In Jerome Groopman’s fascinating New York Times article “What’s the Trouble,” we learn of three specific cases in which skilled physicians, “rely[ing] on shortcuts and rules of thumb... known...as ‘heuristics’” (Groopman 4), fail to make accurate diagnoses concerning the unknown maladies of their subjects. However, since the article is written from the limited perspective of a medical professional, it lacks insight into the heuristic techniques of the patient, the cursory and sometimes imprecise trial-and-error processes which he or she must run through to deduce whether or not their clinician is trustworthy. I would like to discuss the heuristic method which I believe to be the most frequently utilized by patients: unverified trust in the doctor’s good morale simply because he or she…

    The Effect of Salt Concentration on Grass Growth

    Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water, watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt, the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth of the plant. I also had a few difficulties in the duration of this experiment which were the sunlight on the plants direct which made the plants to begin to die and also the highest salinity plant was not growing.…

    Manus Green Tree Snail Case Study

    To help this problem, I.A.R.F’s Environmental Cyber Crimes Unit filed a complaint to EBay about selling the shells of the Manus Green Tree Snail. I would suggest that they have a protective system of the snails and there habitat so that their habitat can get destroyed. Also I would suggest that no company are allow to sell the shell of the Manus Green Tree Snail. I.A.R.F’s Environmental Cyber Crimes Unit would benefit from my suggestion because, they protect animals and my thoughts could really help them get some ideas for protecting the Manus Green Tree Snail. The fact that he shells of the snails is very popular could be a big problem. The reason why this could be a big problem is because the companies that sell the shell wouldn’t really like the idea of not selling the shells because they…

    Snails are one of the earliest known types of animals in the world. There is evidence that they evolved more than 600 million years ago. They are able to adapt to a variety of living conditions and they don’t require large amounts of food. They have been able to continually evolve to survive the conditions around them.…

    Golden Mussel Research Paper

    The golden mussel threaten one of the world's unique environmental systems. Up to now, it has reached the waters of five nations in South America. The golden mussel is a tiny animal that it does not grow more than 1 inch, and it releases tiny larvae that drift with the current to new areas. The golden mussels frequently stick to hard surfaces such as rocks, manufactured structures. The Golden mussels have already effected South America negatively, and it harmed innate clam species. In Brazil and Argentina, the Larvae and little mussels went into hydroelectric and water treatment plants, in addition, they are blocking channels, so the officials are forced to spend a lot of money to remove the mussels per year, and sometimes they kill the mussels…

    Pondwater paper

    “A Pond is commonly described by limnologists as a quiet body of water so shallow that rooted plants grow completely across it. Its water temperature is fairly uniform from the top to bottom and tends to change with air temperature. There is little wave action; and the bottom is usually covered with mud. Typically, plants grow all along the shore. The amount of dissolved oxygen may vary greatly in a 24 hour period.” (Pond Life 2001) There are several environmental factors that are essential in maintaining stable pond life. If any of the factors drastically change the results may increase or decrease the life within the pond. If there is more algae sediment in a controlled environment then more protozoa’s will be observed. If the pond water is in a controlled environment, then the pond life should remain stable.…

    Annona Squamosa (atis) leaves as molluscicide for Golden apple snail

    Farmers, even before has so many issues in their farm and the most common problems of farmers in their farm lots are kuhols, specifically the Golden Apple Snail, which pests their plants. Golden apple snail The Golden Apple Snail is amphibious. While there is a sufficient level of dissolved oxygen in the water, they will hardly leave the water and will breathe by their gills. If the level of dissolved oxygen gets to low, the snails will go up to the surface and breathe with their lung (mostly by using its siphon, a tube that it extracts to the water surface). While filling their lung with air, the snails extract and contract their body, so that the pressure differences cause their lung to deplete and refill. These snails have the ability to cruse away from the aquarium, so a cover glass is a necessity, as they won't survive longer than a couple of days in dry conditions. These snails have a tendency to float around the water surface, "playing dead"- but actually, they are not. The best way to tell these snails are dead is if it doesn't contract when you touch it or if the operculum (shell cover) is missing (mostly at that time, the shell will also be empty). Due to their liking of plant matter as food, most people recommend not to keep them implanted on aquariums. Farmers of crops like “palay” who suffer from the activities of these Golden apple Snails are very unfortunate for having these pests in their farm because it was the perfect pest which can eventually damage your plant in a short period of time. Farmers’ goals when treating this problem about golden apple snail is controlling the mortality rate of the said snails not through…

    Albendazoles Case Study

    Although, in vitro activity of oxyclozanide againstadult Fasciola worms was reported previously (Jeyathilakan et al.,2012). It was surprising to record that oxyclozanide in vitro did notaffect the egg development and egg hatching percentages. Therewas no significant difference in EHA of the control and variousoxyclozanide concentrations. It is of interest to clarify that the abil-ity of drugs to pass through the egg shell and to show its effectdepends mainly on the solubility in the fat layer of the egg shell.Since, oxyclozanide has a hydrophilic nature (Swana, 1999), it maybe not able to pass the fat layer of the egg shell. Consequently, thehatched miracidium showed sluggish movement and it was easy tobe captured beside its empty hatched eggs with open operculum.Praziquantel had no significant effect on either FER or EHA%.Different studies showed failure of human treatment against fasci-oliosis with praziquantel (Farag et al., 1986; Farid et al., 1989; Chai,2013). Such failure may be related to the resistant properties of theF. hepatica tegument. Vacuolization of this layer was observed whenSchistosoma mansoni and Dicrocoelium were treated with prazi-quantel in vitro, but such changes were conspicuously absent…
