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

ETL (Economic Threshold Level) for vectors:
Disease vectors: 1
1.5% (C)
Severe outbreak vectors: 2
2.5% (D)
Lower thresholds than non
vector pests due to disease transmission risk
Zero tolerance not practical in field conditions
