Sand flies can be effectively trapped using specialized devices that attract them with light and then capture them using suction into a collection unit.
Method for Trapping Sand Flies
A common and effective method involves using a portable light trap. This trap is specifically designed to attract sand flies and safely secure them for collection or study. The core principle relies on the sand flies' natural attraction to light sources.
Key Components of a Sand Fly Light Trap
Based on effective designs, a typical sand fly trap integrates several functional parts to achieve attraction, capture, and containment:
- Trap Body: This forms the main structure, often made from materials like an acrylic tube.
- Attraction Source: An incandescent light bulb is housed within the trap body. Its light serves as the primary attractant for sand flies.
- Capture Mechanism: A motor powers a fan. This fan creates airflow that sucks attracted sand flies into the trap body.
- Escape Prevention: The fan also plays a vital role in preventing the escape of collected specimens by maintaining continuous airflow inwards.
- Collection Unit: An insect collection cage is connected to the trap body. This cage is typically made of fine nylon netting and is where the captured flying insects are stored.
How the Trap Operates
The process for trapping sand flies using this type of device is as follows:
- The trap is set up, and the incandescent light bulb is activated.
- Sand flies in the vicinity are attracted by the light and fly towards the trap body.
- As they approach, the running fan creates a powerful suction.
- This suction pulls the sand flies through the trap body and into the attached collection cage made of fine netting.
- The consistent operation of the fan ensures that the trapped sand flies remain secured within the collection cage.
This integrated design provides an efficient way to capture sand flies, which is essential for monitoring populations, conducting research, or implementing control measures.
