Control of garden insects with chromatic traps

These traps are of great help in our garden, some pests are capable of recognizing colors such as yellow, green, blue, red, white and now as a novelty, the black color trap is used with excellent behavior in the capture of tuta absolu ( tomato miner).

These traps are based on the attraction that certain insects have for certain colors. Flies (diptera) and aphids (aphids) have a preference for yellow. The blue color, on the other hand, is preferred by thrips and leafminer flies, green bugs, red moths and beetles. And they can approach them because they attract them, the elaboration of them is low cost, they do not pollute the environment and they are easy to manufacture.

Its function is to prevent the entry of pests into our garden. We can use any type of colored material, eva rubber, chlorine plastic containers, colored glasses, etc. The sticky substance can be a good alternative to vegetable fats or vegetable shortening, at home we use cooking oil.

The mode of action of these traps is based on the attraction of adult insects which remain stuck to the plastic; capturing the adults prevents them from reproducing and thus reduces the presence of larvae (immature stages of these insects) which are the ones that mainly feed on the plants.

The height of the traps should be similar to the height of the crop; these traps should preferably be placed with one side facing where the sun rises, because when the first solar rays are reflected on one face of the plastic, a shine is produced that attracts the greatest number of insects. The times when the greatest capture of insects occurs is during dawn and dusk.

For better control, they should be greased at least every week.
