The use of chromotropic traps it represents a very simple agronomic technique to carry out but also very effective. It has a twofold objective, first of all to monitor the presence of harmful insects inside the vegetable garden or orchard. Secondly, to carry out mass capture. It immediately becomes clear how this particular prevention strategy can become an excellent ally for the biological care of the fields.
There are different colors available, depending on the insect to hit. The effectiveness of this system depends on several factors, among which, the most relevant is the intensity of the placement on the field.

We understand, therefore, in this article, how these traps work, how many variants exist and how to position them. Finally, let's see how to achieve them, without too much difficulty.

What are chromotropic traps

In organic farming, the use of chromotropic traps has been widespread and established for a long time. Quite simply, these are particular sheets or panels, usually plasticized, on which a special glue is applied. The colored sheet attracts the harmful insect and the glue captures it, causing it to remain attached to the surface of the panel itself.
The objective of this type of traps is twofold:

  • Monitoring of harmful insects present in the field. This occurs through direct and periodic observation of the colored panel. Thanks to this trick, we can realize which insects are present on our field, what stage of development they have, how much they are numerically present, and therefore what is the best way to intervene.
  • Mass capture of insects. If the traps are used with a certain intensity in the field, that is, placing many of them at a short distance, in addition to the important monitoring function, we will capture a very high number of insects. The obvious consequences will be: the decrease in their presence and the reduction of damage caused to crops

Yellow chromotropic traps

In general, this type of traps has a very low environmental impact, as long as the panels themselves are disposed of in an ecological way.
In addition, it avoids the introduction of toxic substances into the environment and onto the vegetation of the plants that we are going to protect. The adhesives used, in fact, are specifically designed for agriculture and are designed so as not to melt with the sun and not to drain on the ground.
They do not affect the use of other products permitted in organic farming, such as natural macerates (nettle, garlic, horsetail, fern), the bacillus thuringiensis, the Marseille soap, L'neem oil. Indeed, using chromotropic traps together with other organic remedies synergistically increases the effectiveness of both.

The colors of the chromotropic traps

In nature it is easy to observe how insects are more or less attracted to some shades of color rather than others.
Field trials have shown that the best colors for chromotropic traps are yellow and blue.
Yellow plants attract most of the harmful insects that threaten crops, in particular:

  • The white fly
  • The oil fly
  • The aphids
  • There absoluta tomato suit
  • The cherry fly
  • Flies in general
  • The leafhoppers
  • The foliar miners
  • Some species of cochineal
  • The bedbugs in the stages of nymphs

The blue chromotropic traps, on the other hand, are mainly used for monitoring and mass trapping of thrips. In particular, it attracts the harmful thrips Frankiniella Occidentalis, an insect vector of the terrible virosis of tomato

At the following link you can find effective chromotropic traps, offered at an affordable price. They are ready for use, with directions for use and with specifications for the particular insects that we are going to capture.

Pheromones for insects

To improve the effectiveness of chromotropic traps, especially when practicing intensive cultivation, a pheromone synthetic type.
In simple terms, it is a particular odorous substance, naturally emitted by insects in nature, to attract individuals of the opposite sex. Usually it is the female specimen that emits the pheromone. This is then synthesized and reproduced in order to simulate this signal and attract more individuals into the traps.

Usually pheromones are used in special traps, but, as mentioned, they are often added to the colored trap.
A series of pheromones and traps with this specific function you can find it here.

The positioning of chromotropic traps

Now let's see how and with what intensity to place the chromotropic traps in the garden, for the functions we have just described.

Yellow traps and blue traps

Let's start with the yellow color traps. In open field crops, in the vegetable garden or in the home garden, if you want to proceed only with monitoring, the following distance must be respected: 6 traps per hectare for olive tree cultivation and orchards, 4 traps per hectare for the vineyard, 2 traps every 100 square meters for vegetables.
For massive capture, on the other hand, 1 to 4 traps per plant for olive trees and orchards will have to be arranged, depending on the size of the land and the degree of infestation detected. For mass capture in vegetable crops, the intensity passes to 2 traps every 10 square meters.

It should be emphasized that the traps are harmless to bees. Unlike what one might think, in fact, the simple yellow color does not appeal to them. To attract them, however, the presence of pollen and nectar is necessary, which bees can recognize very well.
In greenhouse vegetables, the indications should be increased by 25-30%, since the presence of harmful insects is more massive.
The traps should always be positioned near the vegetative apexes and raised accordingly as the plant grows.

Blue color trap

For this purpose, suspended wires, wooden poles or bamboo canes such as those can be used found here
Blue color traps are used to control thrips.
For monitoring, 10-12 per 100 square meters should be placed in the pre-flowering phase. Next, it is necessary to check whether the thrips population has a tendency to increase. If so, arrange other traps depending on the degree of infestation.
Also in this case, the traps must be placed at the height of the flower boxes or the highest shoots.
Again, obviously, the traps must be raised progressively following the growth of the plants.

The artisanal chromotropic traps

If you want to make chromotropic traps yourself, just use simple colored plastic plates. These will be made a passage with transparent glue, like the one generally used for paper.
The advantage of do-it-yourself is certainly represented by the economic savings, however there is the big unknown factor of the instability of the glue used. In fact, if used in excess or if exposed to high temperatures, it can melt and run easily into the ground, introducing harmful substances.

Organic cultivation

Organic Cultivation is a blog that was born from our desire to spread the good practices of organic farming. To do this we decided to give our knowledge to anyone who wants to get involved and create their own vegetable garden (even using a terrace or a simple balcony). Growing without the use of pesticides is possible and we want to prove it by presenting alternatives biological and effective for any type of problem linked to agriculture.


The traps for monitoring in the organic orchard

In an organic orchard it is important to identify threats early and to recognize in time the presence of insects harmful to fruit plants. Monitoring by means of traps is one of the best preconditions for their control, both in professional and amateur orchards. With these tools it is possible to know the presence of the phytophagous populations in a timely manner and consequently seize the right moment to carry out specific, targeted and waste-free treatments.

In professional organic fruit growing, planning and managing a good monitoring of insects is particularly advantageous, since in this type of management the problems cannot be solved by treating the plants with insecticides with a strong killing effect, but instead it is necessary to work on prevention and then act promptly to the first symptoms of an adversity.

Among the various lines of intervention to protect fruit plants, insect monitoring therefore plays a decisive role. It becomes important to inform yourself well about the existing traps and their different operating principles to then choose the one that seems most suitable.


Chromotropic traps: colors

The chromotropic traps are made in three colors:

  • yellow
  • light blue
  • White

-The yellow traps are used for the control of the cherry tree fly, of the olive tree, of the fruit, of the olive moth, of the white fly, of the leafhoppers, of some miners, aphids and scaridae. They have the defect of being not very selective and therefore also attract other insects, not only the "neutral" ones but also those useful for the defense of the crop.
-The light blue traps are particularly suitable for catching thrips: one or two are enough every 50 square meters to already have excellent results.
-The white traps are very suitable for monitoring and capturing the pear sawfly and are one of the most effective interventions in case of attack of this parasite


The Chromotropic Traps

The chromotropic traps are colored bands, or tags, created in various shapes and coated with glue whose principle of operation is based on the power of attraction that the various colors exert towards pests.

They are built with waterproof and weather resistant material, the attractive substances with which they are impregnated they do not present any toxicity for humans or even for the environment, are for this reason used in organic and biodynamic crops.

They can be a valid system for evaluating the most appropriate time to intervene, if necessary, with the treatments, they can therefore be used both as preventive and as curative.
In fact, by carrying out the massive capture for example, the traps are placed in greater number, 7/8 per 50 square meters. of greenhouse obtaining the result of a considerable reduction of pests in the environment, as a quote we said the evaluation of the number of pests present, placing 7/8 traps in 1000 square meters. of the greenhouse it is then possible by counting the number of adults captured to get an idea about the general situation, an idea about possible treatments.

The chromotropic traps are divided into three colors:

  • YELLOW
  • LIGHT BLUE
  • WHITE

The yellow chromotropic traps, they are used, in particular, for the control of the cherry tree fly, the olive tree, the fruit, the olive moth, the whitefly, the leafhoppers, some miners, aphids and scaridae.

The light blue color traps, are indicated for the capture of thrips.
In case of throwing insects auxiliaries it is not necessary to remove the traps as they are sufficiently selective.

The color and white color traps they are useful for monitoring and capturing pear sawflies.

These traps are also useful in case it is necessary to treat isolated and large plants for which it is difficult to carry out treatments with home methods.

The chromotropic traps, as we said they are useful in monitoring the populations present in the places of cultivation and represents a valid support for identifying the treatment to be used and when to intervene.

Through the periodic control of the captured insects it is possible to assess the degree of infestation and with a good approximation establish the most appropriate time to intervene.
For proper use, the traps, must be placed well in advance of the period of fluttering of the parasites, and in a sufficient number, at least ¾ per hectare and these, for the majority, must be replaced approximately every 20 days.

This technique, correctly used allows not only a savings in money, but above all, allows a great one reduction in the use and therefore in the emission of pollutants into the environment what are the products used for the care of crops so much so that, over time, they have gained more and more land for those who cultivate by following eco-compatible practices.

In fact, thanks to these traps it is possible to make the most of the effectiveness of natural pesticides.
Traps are currently on the market for monitoring more than one hundred insects harmful to fruit crops, wineries and flowers, but not only, there are also for domestic environments, suitable, in this case in the specific massive capture of flies, mosquitoes, cockroaches and other little animals.

The use of chromotropic traps for massive capture involves the positioning of a large number of traps efficiently positioned and designed to capture up to 90% of the pests present.

Generally traps for massive capture they are equipped with a funnel-shaped opening equipped with a special bag designed to collect the parasites attracted by the pheromones.

The synthetic pheromonemoreover, it is highly competitive with the natural one of females and acts at greater distances.

In particular, we would like to point out the effective stratagem adopted by our reader Giuseppe Monti who uses the cremini containers to build DIY traps capable of catching harmful insects without attracting the useful ones.

  1. To begin, make two small holes in the top of the bottle in order to pass the hooks of the underwire.
  2. Drill two holes in the bottom of the container as well of the cremino in order to pass the ferretti: make sure that the container of the cremino is yellow.
  3. Pour into the bottle two tablespoons of sugar, a glass of vinegar and enough water to cover almost half the bottle.
  4. The container must slide along the underwire and must not close the entrance to the trap.

Certain types of insects are attracted to specific colors. Once in contact with the adhesive plate of the trap, the insects stick and die.
The chromotropic adhesive traps allow an effective and 100% natural fight in respect of the environment.
They are rectangular sheets made of waterproof material and resistant to atmospheric agents. Furthermore, the attractive substances with which they are impregnated have no toxicity for both humans and the environment: for this reason they are used in organic and biodynamic crops.

They can be used in two ways: Monitoring of crops or defence of the same through mass capture.

1. Monitoring:
The chromotropic traps are useful in monitoring the populations present in the places of cultivation and represent a valid support for identifying the treatment to be used and when to intervene.
In this case, about 7 traps are generally needed for every 1000 square meters of surface distributed evenly to monitor the presence of harmful insects and better plan any subsequent defense interventions, understanding for example the best time to operate.

2. Mass capture:
Instead, if you want to make a massive capture, the number of traps must increase considerably and the same 7 traps must be distributed in a much smaller area, which usually does not exceed 50/100 square meters. When all the gluey surface is covered with insects, the trap has done its job well and must be replaced as it is no longer effective.

Da sottolineare che le trappole sono innocue per le api. A differenza di quel che si potrebbe pensare, infatti, il semplice colore non le attira. Per attrarle, invece, u00e8 necessaria la presenza di polline e nettare che le api sanno riconoscere molto bene.

Per migliorare lu2019efficacia delle trappole cromotropiche, specie quando si praticano coltivazioni intensive, si aggiunge un feromone di tipo sintetico. Si tratta di una particolare sostanza odorosa, naturalmente emessa dagli insetti in natura, per attrarre individui del sesso opposto.

Di solito u00e8 lu2019esemplare femmina che emette il feromone. Questo viene poi sintetizzati e riprodotto in modo da simulare questo segnale e attrarre nelle trappole piu00f9 individui. Solitamente i feromoni vengono utilizzati in apposite trappole, ma, come detto, spesso sono aggiunti alla trappola colorata.

Le trappole vanno posizionate sempre nelle prossimitu00e0 degli apici vegetativi e alzate di conseguenza man mano che la pianta cresce. ","description_short":"
