Automatic Insect collector / Aspirator With Counter

The inner chamber size (35 cm x 35 cm x 35 cm) of the VSI IR-735 Insect Aspirator is suitable for standard rearing cages ('target cages') up to 33 cm side length. Insects are captured in the source cage via a vacuum pipe ("pick-up straw") with variable hose length; the associated ventilator for creating the suction force is screen mesh protected and positioned below the target cage. Insect collection is started/stopped via a foot switch for easy, hands-free operation. As insects are entering the target cage, their number is counted with a photo sensor and the collected number is displayed. The device requires 220 V.  Please see the IR-735 specifications (pdf file) below or contact us for details. The device can be custom-made to fit any insect cages sizes.

Flying insects can be collected using a variety of methods, largely depending on the collection site, species and scope. Some common techniques are:

• Sweep netting or other nets: This method involves using a large net, usually of fine mesh, to sweep through vegetation or other habitats where flying insects may be present. The net is swung through the air to catch insects in flight or to collect them from foliage. Other techniques use installed nets with colelctions flasks on top. Partially thes nets have different colours for effective collection. 
• Light traps: Light traps use ultraviolet light to attract and capture nocturnal flying insects such as moths and beetles. The trap consists of a light source and a receptacle that can be filled with water or other liquid to preserve the insects.
• Sticky traps: Sticky traps are adhesive surfaces placed in areas where flying insects are likely to land or fly through. The traps can be made of various materials, such as paper or plastic, and can be coated with a non-toxic adhesive. This methodology is not suitable if insect have to be captured alive. 
• Pheromone and similar chemical traps: Pheromone traps use sex pheromones or other attractants such as CO2 to lure certain species of flying insects into a trap. The traps typically consist of a lure or bait placed in a container.
• Vacuum sampling: This method uses a portable vacuum device to suck flying insects from vegetation or other habitats. The insects are collected in a container or bag attached to the vacuum. The VSI insect aspirator follows this principle to transfer insects carefully and in known numbers between insect rearing cages.. 
• Knocking or shaking: Moving branches or leaves can dislodge flying insects and cause them to fall onto a collection sheet or into a container placed underneath.
• Manual collection: At lowered temperatures, inmobilised insects can be transferred manually.

The choice of collection method will depend on the specific objectives of the study, the habitat and insect species of interest and the resources available. It is important to choose a method that is appropriate for the target insects and minimises harm or damage to the collected specimens.
