Molluscicidal Effects
TOPIC PROPOSAL NO. 1
Proposed Title:
MOLLUSCICIDAL EFFECTS OF SAMBONG (BLUMEA BALSAMIFERA, SAN FRANCISCO (CODIAEUMVARIEGATUMAND, AND MAKAHIYA (MIMOSA PUDICA)ON FRESH WATER SNAIL: A BASIS FOR
LABORATORY ACTIVITY DEVELOPMENT
Rationale
Schistosomiasis is one of the most important and rapidly spreading parasitic diseases of mankind, a growing threat to large- scale irrigated agriculture and hydroelectic power development schemes in many tropical countries. T he role of molluscicides can play in effective control of schistosomiasis and other snail borne diseases of human and livestock. Unfortunately, chemical molluscicides pose a great health risk especially to those people who are in agricultural sector. As a consequence of the constraints to chemical molluscicidal use, interest in plants with molluscicidal properties has increased. The reasercher has the desired to determine the molluscicidal effects of some selected Phillipine plants on the fresh water snail and develop activities that can be used as laboratory activity based on this investigation. Purpose of the Study To determine the molluscicidal effects of sambong, San Francisco, and makahiya to freshwater snail. To develop awareness among the students of other properties of the selected plants. To develop a laboratory activity based on the investigation.
Research Questions The proposed research questions will include but are not limited to the following: 1. Which plant extract that will exhibit the hignest mortality rate of fresh water snail? 2. Is there any significant difference between the performance of the leaf extract and the commercial molluscicides in terms of the mortality of fresh water snail? 3. What enrichment activity can be developed from this investigation that could be utilized in biology class?
Proposed Methods in Answering the Research Questions The proposed methods in answering the research questions are as
