(c) Vector of virus.

(d) All of the above.

Ans: (d) All of the above.

C. Subjective questions:

1. Explain brinjal’s fruit and shoot borer and its control measures.

Ans: Brinjal’s fruit and shoot borer (Leucinodes orbonalis) is a serious pest that affects brinjal crops by boring into the shoots and fruits, causing wilting and fruit damage. The life cycle of this pest includes egg, larva, pupa, and adult stages, with larvae being the most destructive as they feed inside plant tissues. Symptoms of infestation include dried and wilted shoots, holes in fruits with visible frass, and damaged fruits unsuitable for consumption. To control this pest, several measures can be adopted. Cultural practices such as field sanitation, crop rotation, and using resistant varieties help reduce infestation. Mechanical methods like hand-picking infested shoots and using pheromone traps to attract and trap adult moths can also be effective. Biological control involves introducing natural enemies such as Trichogramma chilonis, an egg parasitoid, and predators like Chrysoperla carnea. Chemical control includes spraying insecticides such as neem-based products, Spinosad, Emamectin benzoate, and Cypermethrin at the recommended doses during the early stages of infestation. An integrated pest management approach combining cultural, mechanical, biological, and chemical methods is the most effective strategy to minimize damage and ensure a healthy brinjal crop.

2. What are the control measures of tomato’s fruit borer?

Ans: The control measures of tomato’s fruit borer are mentioned below: 

(i) Use tolerant varieties like Punjab Kesari, Punjab Chhuhara, BT-1 and BT-32.

(ii) Deep summer ploughing can expose the larvae and  pupae to sunlight and predation of birds.

(iii) Plant marigold (40 days old) as a trap crop with every 16 rows of tomato (25 days old) to attract the larvae. Collect the larvae from the marigold flowers and  destroy them.

(iv) Place 15-20 T-shaped bird perches per ha to invite  insectivorous birds.

3. Write about chili’s fruit borer and its control measures.

Ans: The fruit borer is one of the most destructive pests in chilli cultivation, causing substantial yield losses and reducing the quality of produce. Timely identification and effective management are crucial to minimize damage.

Control Measures:

(i) Cultural Control:

(a) Crop rotation, timely sowing, and sanitation (removing infested fruits).

(b) Trap crops (marigold, pigeon pea) to attract borers.

(ii) Mechanical Control:

(a) Handpick larvae and use pheromone traps (5–10/acre).

(iii) Biological Control:

(a) Use Trichogramma chilonis, Chrysoperla carnea, and Bacillus thuringiensis (Bt).

(iv) Chemical Control:

(a) Neem-based insecticides (5% NSKE).

(b) Sprays: Spinosad, Emamectin Benzoate, Indoxacarb.
