To solve the question regarding the formation of the anterior wall, roof, and floor of the genital pouch in the female cockroach, we can break it down into the following steps: ### Step 1: Understand the Structure of the Female Cockroach The female cockroach's body is divided into three main parts: the head, thorax, and abdomen. The genital pouch, which is part of the reproductive system, is located in the abdomen. **Hint:** Remember the three main body parts of cockroaches: head, thorax, and abdomen. ### Step 2: Identify the Genital Pouch The genital pouch in female cockroaches serves as a receptacle for the reproductive organs. It is formed by specific abdominal sterna. **Hint:** Focus on the role of the genital pouch in reproduction. ### Step 3: Locate the Abdominal Sterna The abdominal segments of the cockroach are numbered, and the genital pouch is formed by the 7th, 8th, and 9th abdominal sterna. The anterior wall, roof, and floor of the genital pouch correspond to these segments. **Hint:** Recall the segment numbers associated with the genital pouch. ### Step 4: Determine the Specific Sterna - The **anterior wall** of the genital pouch is formed by the **8th abdominal sternum**. - The **roof** of the genital pouch is formed by the **9th abdominal sternum**. - The **floor** of the genital pouch is formed by the **7th abdominal sternum**. **Hint:** Pay attention to the specific roles of each abdominal sterna in forming the genital pouch. ### Step 5: Conclude the Answer Thus, the anterior wall, roof, and floor of the genital pouch in the female cockroach are formed respectively by the 8th, 9th, and 7th abdominal sterna. **Final Answer:** The anterior wall, roof, and floor of the genital pouch are formed respectively by the 8th, 9th, and 7th abdominal sterna.
