Question

The ETL for insect vectors in pest management is:
(A) 0%
(B) 0 to 0.5 %
(C) 1.0 to 1.5 %
(D) 2.0 to 2.5 %
Choose the correct answer from the options given below:

• (A) and (B) only
• (A) and (C) only
• (B) and (C) only
• (C) and (D) only

Hint:

ETL for vectors is typically 10x lower than for non-vector pests of the same crop.

Answer 1

The Correct Option is D

Step 1: Eliminate 0% (A) since a zero-tolerance threshold is not field-practical.
Step 2: Eliminate 0 to 0.5% (B) as too low to be a standard recommendation.
Step 3: Vector ETLs are set low due to disease-transmission risk, matching the 1.0-1.5% (C) and 2.0-2.5% (D) ranges used together.
Step 4: The correct option is (C) and (D) only.
