Aphid

Bacillus thuringiensis, the ladybird beetle and Trichoderma are all well-known biocontrol agents used respectively against insect larvae, aphid pests, and soil-borne plant pathogens. An aphid, however, is itself a common crop pest that natural enemies like the ladybird beetle are used to control, so it is NOT a biocontrol agent, making option (d) the correct answer.
