The Rice Yellow Stem Borer (YSB) is one of the most damaging pests in rice cultivation across Asia, including India. The larvae bore into rice stems, leading to deadhearts during vegetative stage and whiteheads at panicle stage, causing severe yield losses. Early monitoring with pheromone traps, combined with Integrated Pest Management (IPM), is critical to reduce crop damage and pesticide use.

Host Crop:

• Paddy (Oryza sativa) – main host

Damage Symptoms:

🌱 In Vegetative Stage:

• Deadhearts – central shoot wilts and dries up

• Easy to pull out the central shoot from the base

🌾 In Reproductive Stage:

• Whiteheads – empty panicles without grains

• Panicles stand erect and appear white

👉 Yield loss can range from 10–60%, depending on the infestation severity and growth stage.

Pest Lifecycle:

1. Eggs are laid in clusters on leaf sheaths

2. Larvae bore into rice stems and feed internally

3. Pupation occurs inside the stem

4. Adults are yellowish moths with a single black spot on each forewing (males)

🕒 Lifecycle duration: 25–35 days, with multiple overlapping generations per season.

Monitoring & Control Using Pheromone Traps:

✅ Recommended Trap Type:

• Funnel Trap / Delta Trap

• Weatherproof design preferred for paddy fields

✅ Lure Type:

• Scirpophaga incertulas sex pheromone lure

✅ Trap Density:

• 4–5 traps per acre for monitoring

• Start trapping 15–20 days after transplanting

• Monitor weekly for moth catches

🟢 Pheromone traps enable early detection, allowing farmers to intervene before economic threshold levels are reached.

Other IPM Strategies:

🌱 Cultural Practices:

• Timely planting and synchronized sowing

• Avoid staggered planting in the same area

• Remove stubble and plough field post-harvest
