A yellow sticky trap is a simple but very effective pest control tool used in agriculture—especially in vegetables, fruits, and greenhouse crops.

 What it is

A yellow sticky trap is a bright yellow card or sheet coated with adhesive glue that attracts and captures flying insect pests.

কেন কাজ করে 

Many harmful insects are naturally attracted to yellow color, such as:

• Whiteflies (সাদা মাছি)
• Aphids (এফিড)
• Leaf miners
• Thrips
• Jassids

They fly toward the yellow surface and get stuck on the glue.

Uses in Farming

1. Monitoring (পর্যবেক্ষণ)
   Helps you understand pest population early.
2. Control (নিয়ন্ত্রণ)
   Reduces pest numbers without chemicals.
3. IPM (Integrated Pest Management)

How to Use

• Height: Crop canopy level (গাছের সমান উচ্চতায়)
• Spacing:
  • Monitoring: 10–15 traps per acre
  • Control: 25–40 traps per acre
• Placement: Evenly across field or greenhouse
• Replace when sticky surface is full/dusty

Tips

• Avoid touching glue (very sticky)
• Keep away from beneficial insects area if possible
• Combine with pheromone traps or neem-based spray for better results

Example (for your crops like cucumber, gourd, okra)

Yellow traps are highly useful in:

• Cucumber & gourds → whiteflies & aphids control
• Okra → jassid & aphid monitoring
