1. Insecticide Research and Development and Bioassay Group 5 Presentation General Physiology and Toxicology

2. A. Research and Development Process - Refers to the systematic process of discovering, designing, and testing new insecticides. - It involves identifying target pests, formulating active ingredients, and evaluating efficacy. - The goal is to develop safe, effective, and environmentally sustainable insecticides. - Stages include laboratory research, field trials, and regulatory approval. - Focuses on innovation, safety, and improved pest management solutions.

3. B. Data Generation and Their Value of Safety - Data generation involves collecting experimental and field data during insecticide development. - Ensures that products meet safety and environmental standards. - Data includes toxicity levels, mode of action, and environmental persistence. - Regulatory agencies use this data to assess risks to humans, animals, and ecosystems. - Proper data supports product registration and public trust.

4. C. Economic and Legal Aspects of Insecticide Use - Economic factors include production costs, market demand, and profitability. - Legal aspects cover government regulations, licensing, and product labeling. - Laws ensure safe handling, storage, and disposal of insecticides. - Compliance protects consumers, applicators, and the environment. - Non-compliance can result in penalties, bans, or product withdrawal.

5. D. Types of Bioassays and the Factors to Consider - Bioassays test the effectiveness and toxicity of insecticides on target organisms. - Types include laboratory, greenhouse, and field bioassays. - Factors to consider: test organism, environmental conditions, dosage, and replication. - Bioassays help determine lethal concentrations (LC50) and effectiveness levels. - Ensures reliability and consistency of results.

6. E. Probit Analysis - A statistical method used to analyze dose-response relationships. - Helps determine the median lethal dose (LD50) or concentration (LC50). - Converts percentage mortality into probits to establish a linear regression line. - Commonly used in toxicology and pesticide evaluation. - Ensures accuracy in assessing insecticide potency and safety.
