These seductive plants will keep your farms safe from insects

Spain: It is astonishing to know how a tree can help us get away insects from our farms. These trees release a particular kind of chemical named Pheromone. Pheromone traps are often used to catch certain species of insects (mostly stored product insects), and in these traps a pheromone attractant is used to lure insects. Once attracted, a sticky board or catching bucket captures the insect.

Pheromones are sex attractants which attract only males of various species of insects. These types of trap are not used to control insects (females remain alive), but instead are used to demonstrate the presence of insects. Many different types of insect pheromone attractants are available, like:

  • The clothing moth (Tineola bisselliella);
  • The Mediterranean flour moth (Ephestia kuehniella);
  • The cacao moth (Ephestia elutella);
  • The Indian meal moth (Plodia interpunctella);
  • The tobacco beetle (Lasioderma Perricone);
  • The carpet beetle (Anthrenus verbasci);
  • The confused flour beetle (Tribolium confusum).

Since many of the insects that are attracted by pheromones live in a dusty environment, the use of glue boards to capture these insects is less suitable as the glue often dries rapidly under dusty conditions. Glue boards can therefore only be used when they are checked and replaced very frequently.

Insect pheromone traps are inspected at least 8 times a year, and the trapped insects are then counted and the species determined. The results are recorded in the pest control program.
