Question

One of the major difficulties in the biological control of insect pests is that

B. The predator does not always survive when transformed into a new environment.
C. The method is less effective as compared with the use of insecticides.

Complete answer:
The predator develops a desire to genuinely other diets and can itself turns into a pest; is one of the pretty main difficulties in the biological control of insect pests, or so the idea. organic manage is a component of an included pest control approach reduces the pest populations by fairly natural enemies and generally entails a truly energetic without a doubt human position, kind of further displaying how the predator develops a preference to surely other diets and might itself becomes a pest; is one of the kinds of main difficulties inside the honestly biological manipulate of insect pests in a for all intents and functions big way. natural enemies of insect pests, additionally referred to as very biological manipulate sellers, for all intents and purposes consist of predators, parasitoids, and pathogens, demonstrating how the predator develops a choice to for all intents and purposes other diets and might itself will become a pest; simply is one of the main problems inside the organic control of insect pests, which is pretty full-size.

One of the major difficulties in the biological control of insect pests is that predators develop a preference for other diets and may itself become a pest.

Hence, the correct answer is option (A).

Note: The truly predominant businesses of insect disorder-causing organisms are insect-parasitic bacteria, fungi, protozoa, viruses, and nematodes, which is quite widespread. One very microbial manipulate agent that for all intents and functions is available commercially mainly is the bacterium Bacillus thuringiensis (Bt), displaying how the essentially essential organizations of insect sickness-causing organisms for the most component are insect-parasitic bacteria, fungi, protozoa, viruses, and nematodes subtly.
