WHAT PHEROMONES ARE AND HOW TO USE THEM TO CONTROL INSECTS
In all activities and in all product sectors, weed pests create damage to people’s health, goods and cause damage to image. Of course, no one can say that they are safe or even free from these problems, because they do not depend on us, but on where we live. Insects are inherent in the environment and around us, so the only things we can do are:
- Create physical barriers such as mosquito nets, air curtains, pre-entry barriers and so on.
- Remove possible causes of proliferation such as waste management, uncultivated green areas, etc.
- Continuously monitor their presence.
However, the best way to control the presence and spread of insects indoors is to use attractive sex pheromones.
Pheromones are commercially available in various forms, such as ampoules and/or small plastic supports. Inside these supports are contained specific substances, called pheromones, which are attractive to the various types of insects. Usually there are different pheromones for each species of insect, but there are also pheromones that work on the whole family, such as that of the Moth.
It is important to know that there are many types of pheromones and then choose the one that suits us: pheromones cover not only the cereal areas, but also the areas of textiles/wools, greenery, dried fruit, feedstuffs, tobacco, aromatic herbs and infusion/tisan herbs and many other cases.
The attraction inside the support has the task of simulating the presence of a female and this allows to attract the males. In order to capture the pests you will need traps in which to place the pheromone.
You can find different models but normally the most effective are funnel traps or glue surface traps. At this point you just need to place the pheromone (choose carefully the type for the insect you want to capture) in the trap and you’re done. We recommend placing a suitable number of traps in the place of interest, so that they are evenly distributed over the areas to be treated.
As for the duration of pheromones, once placed they degrade over time and should be replaced periodically. Normally the duration ranges from 30 to 60 days depending on the type and conditions in which they are placed. Furthermore, they do not contain substances that are dangerous and/or harmful to our health and to food.
Now that we have an overview of the types of pheromones and traps, we would like to show you how you should behave in environments where food is present in order to ensure food safety and to solve the problem of living with insects.
The correct procedure for internal pest control is as follows:
- risk analysis and therefore potential pests based on the processing and food substances present;
- definition of catch thresholds: basically you have to decide what is the maximum number of tolerated insects above which non-compliance is triggered;
- define what action should be taken in case of exceeding thresholds or non-compliance and when it should be carried out;
- set up a monitoring system, on all areas, with specific traps with numbered pheromones;
- periodic control programme of each trap;
- recording the number of catches on reports;
In reality, these procedures are more difficult to put in writing than to follow: once we have set up the work, they are very effective and very low cost.
Using pheromone traps, means having an effective pest control system (capture of males, i.e. blocking the proliferation process) that works 24 hours a day for 365 days a year. In addition, these systems guarantee to reduce the use of insecticides to a minimum, only in cases where they are strictly necessary.
