Question

CRC stands for

• A. Chawkie Rearing Committee
• B. Chawkie Rearing Capability
• C. Chawkie Rearing Centre
• D. Chawkie Rearing Culture

Hint:

"Chawkie" refers to young silkworms, and a "Centre" is the facility where they are reared under controlled conditions before being distributed to farmers.
Combining these gives Chawkie Rearing Centre.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
In sericulture (silkworm rearing), the larval cycle of the mulberry silkworm (Bombyx mori) is divided into five distinct instars separated by molts.
The rearing of the first two young instars requires highly precise environmental controls and hygienic conditions, which differ from the requirements of late-age larvae.

Step 2: Detailed Explanation:
Young silkworm larvae (1st and 2nd instars) are called "chawkie" or "chawki."
These early-stage larvae are highly sensitive to fluctuations in temperature and relative humidity, and are vulnerable to infectious diseases (such as flacherie or grasserie).
They require high temperatures (26–28\( ^\circ \)C), high relative humidity (85–90%), and tender, nutrient-rich mulberry leaves to grow uniformly.
Because most small-scale farmers lack the specialized equipment needed to maintain these conditions, sericulture departments establish Chawkie Rearing Centres (CRCs).
A Chawkie Rearing Centre (CRC) is a specialized, commercially managed facility where silkworm eggs are hatched and reared under scientifically controlled, hygienic conditions up to the second molt.
Once the larvae complete the second instar and are more resilient, they are distributed to local farmers for late-age rearing (3rd, 4th, and 5th instars) until cocoon spinning.
The use of CRCs improves larval survival rates, ensures uniform growth, and increases overall cocoon yield for farmers.
The other options provided — Committee, Capability, and Culture — are incorrect.
Therefore, CRC stands for Chawkie Rearing Centre.

Step 3: Final Answer:
In sericulture, CRC stands for Chawkie Rearing Centre.
