Q287

The non-preference insect resistant mechanism is known as

A.
Anticholorosis
B.
Antibiosis
C.
Antixenosis
Answer
D.
Antipheromonosis

Answer: Option C

Solution

Answer: Option C
Solution:
The non-preference insect-resistant mechanism is known as Antixenosis.
Antixenosis operates by disrupting normal arthropod behaviour, whereas antibiosis adversely affects a pest's physiological processes, thereby impairing arthropod survival, growth, development and behaviour.
It affects the behaviour of an insect pest and is usually expressed as non-preference of the insect for a resistant plant variety as compared with a susceptible crop variety.
