Leiodelt is intended for the trapping of truffle beetles (Leiodes cinnamomeus), thus reducing or eliminating damage by leiodes caused by the same adults and their larvae on truffles.

It is composed of:

  • The Leiodelt trap consists of a yellow-orange hemispherical base, 1 mm thick, with three entry points containing 7 lateral tubes 8mm in diameter and 12mm long, which facilitate the entry of the leiodes and at the same time make it impossible for them to exit. 
  • A 1mm thick transparent plastic lid, with UV protective treatment for increased durability, which is attached to a hanging bracket. 
  • The Leiodelt attractant is a plastic vial containing 50ml of attractant inside. The vial is closed with a plastic cap and sealed with aluminium foil. The scent of the attractant diffuses through the walls of the vial. 

How to apply it

  1. Bury the Leiodelt trap in such a way that the upper row of entrance holes is flush with the ground and the lower row is buried.
  2. Once the trap is in place, open the bag containing 5 Leiodelt attractants and place one inside the trap, fitting it into the base of the trap.
  3. Finally, place a tile over the lid of the Leiodelt Trap to prevent direct exposure to the sun.
  4. When the first catch of leiodesis detected, pierce the aluminium seal with a pen, twig or similar (NEVER with a knife or sharp object, as this could damage the plastic cap underneath the aluminium seal).

When to apply it

At the beginning of September we will install the Leiodelt Pack (Trap + Attractant) in the field. Once we detect the first catch we will pierce the aluminium seal of the Leiodelt attractant (without damaging the plastic cap underneath). 

How many to place

If the season before the present one was the first with beetle damage in the plantation, 30 units per hectare shall be placed.

In the case of a plantation that has experienced beetle damage for several years, you should place between 60 and 80 units.

When to withdraw it

Withdraw the Leiodelt Pack once the truffle harvesting campaign is over.

Leiodes cinnamomeus




El Leiodes cinnamomeus es un coleóptero de la familia Leiodidae

Leiodes cinnamomeus is a coleopteran of the family Leiodidae

  • Eggs. Females deposit them near or on the truffle, measuring between 1.3 and 1.4 mm, round and white and enveloped in a translucent, transparent mucilage.
  • Larvae. They are whitish in colour, but depending on the individual, the colouring may vary to yellowish. They have stout legs, a large head and no eyes. They have powerful jaws with which they dig tunnels in the truffle. The larva has ringed segments and can curl over its torso. The larva of Leiodes cinnamomeus differs from the truffle fly larva in that the latter, typical of Diptera, is cylindrical in shape, has no segments or legs and cannot curl over its torso.
  • Adults. These follow crepuscular habits. When they emerge they are reddish or light brown in colour and become darker as they age. They show sexual dimorphism in the hind legs, the male has a spur on the femur and a curved tibia.


In contrast, the female does not have a dewclaw and the tibia is straight.

Daños Leiodes cinnamomeus

 The initial damage they cause to the truffle is a reduction in its weight, devaluing its aromas and commercial category, and they also indirectly influence early ripening and rotting of truffles.
