Alternate approach - match pest to host/feeding damage rather than recalling the name directly:
Helopeltis antonii is a piercing-sucking bug whose feeding on tender tea shoots produces dark, sunken lesions resembling mosquito bite marks - exactly the symptom called "mosquito blight" - so this pest fits the disease name by its damage pattern.
Heliothis zea, in contrast, is a lepidopteran caterpillar (the corn earworm/bollworm) that chews foliage and bolls of field crops such as maize and cotton; it has no recorded association with tea and does not cause the characteristic blight symptom.
Because the damage symptom and host both point to Helopeltis antonii, Statement (I) is correct while Statement (II), naming an unrelated crop pest, is incorrect.
