To protect the garden, chromotropic insect traps are an effective and practical solution. Do you know what they are and how they work?
Chromotropic traps look like colored sheets or panels, usually plasticised, on which glue is applied. The insect, attracted by the color, approaches the trap and remains glued to its surface. The color of the traps changes according to the type of insect to be caught. Through the use of chromotropic traps it is possible, on the one hand, to monitor the presence of harmful insects to see what types of insects have targeted the garden and the degree of infestation. On the other hand, the traps allow the mass capture of insects. The adhesive on the traps is designed not to melt in the sun and not to be eliminated by the rain. An important advantage of these tools is the reduced environmental impact, since the adhesive does not drip on the ground does not generate dispersions; the system is also an alternative to the use of chemical insecticides or in any case allows a significant reduction in use.
Chromotropic traps: the remedy against flies, aphids, bugs and thrips
The most common chromotropic traps are yellow, used for a large number of insects, and blue. The yellow attracts: white fly, oil fly, aphids, tomato absoluta, flies in general, buzzers, foliar miners, nettles, some species of cochineal and bugs. Blue, on the other hand, attracts thrips. The effectiveness of the traps can be increased thanks to the addition of pheromones, odorous substances naturally produced by the female specimens of the insects to attract specimens of the opposite sex.
Traps, what to buy and how to place them
On the market you can find ready to use chromotropic traps, of different colors, with or without pheromones. The number of traps to be placed changes depending on whether you want to do a simple monitoring or if you want to capture insects massively. In the latter case, the traps will be more numerous and concentrated. In the case of crops grown in the garden, you go from 2 yellow traps every 100 square meters for monitoring, to 2 yellow traps every 10 square meters for massive capture. It is good to remember that the traps should be placed near the vegetative apexes and raised as the plant grows.
Sala Laurus suggests the use of Temoocid C/Trap adhesives (available in 3 variants: for White Moscow, for Thrips, for Absolute Suit), or pheromone traps like Solabiol capture insects (in the shop you can find different types – vegetable garden, citrus fruits, vine, olive grove, fruit, ornamental plants – depending on the cultivation and the insect to capture). Practical and ready to use, these traps are not poisonous, odourless, long-lasting, do not contain toxic or polluting substances, are resistant to humidity and weather and do not dry easily.
