Question

Match List I with List II:
List I:
A. Grasserie
B. Muscardine
C. Flacherie
D. Pebrine
List II:
I. Nosema
II. Bacteria
III. BmNPV
IV. Fungus
Choose the correct answer from the options given below:

• A. A-III, B-II, C-IV, D-I
• B. A-III, B-IV, C-II, D-I
• C. A-III, B-I, C-IV, D-II
• D. A-IV, B-III, C-I, D-II

Hint:

Remember:
- Grasserie = Virus (BmNPV).
- Pebrine = Protozoa (Nosema).
- Muscardine = Fungus.
- Flacherie = Bacteria/mixed.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Sericulture involves rearing silkworms for silk production, where management of various infectious diseases (viral, bacterial, fungal, and protozoan) is essential to prevent colony collapse.

Step 2: Detailed Explanation:
Let us match the silkworm diseases with their causal agents:
A. Grasserie: A major viral disease caused by Bombyx mori Nucleopolyhedrovirus (BmNPV) (III).
B. Muscardine: A fungal disease, most commonly white muscardine caused by Beauveria bassiana, hence matched with Fungus (IV).
C. Flacherie: A disease of the digestive tract, primarily caused or aggravated by pathogenic Bacteria (II) (such as Streptococcus or Bacillus species).
D. Pebrine: A highly destructive protozoan disease caused by the microsporidian parasite {Nosema bombycis (I).
Therefore, the correct match is:
A-III, B-IV, C-II, D-I

Step 3: Final Answer:
This matching corresponds to option (B).
