Lasioderma serricorne

The cigarette beetle, Lasioderma serricorne, causes extensive damage to stored tobacco, both raw tobacco and the manufactured product.

This insect also feeds on different products of animal and plant origin: seeds, grain, cocoa and packaged food products that have been stored for long periods of time. In addition, it is a serious pest causing particular damage to herbaria plant specimens.

The adult can easily perforate thick plastic containers and cardboard boxes, causing serious problems in packaged food products, which cannot be sold.

MORPHOLOGY AND BIOLOGY

The adult beetles are small, oval-shaped and a yellow-reddish or brown-reddish colour. They measure from 2 to 2.5 mm long. Their head is bent forward almost at right angle to their body, so they seem to have a pronounced humpback when looked at from the side.

The larvae are a white-yellowish colour. Each larva has three pairs of legs and a brown head. They can measure from 2 to 3 mm.

The adult beetle has a life cycle lasting 2 to 4 weeks. The adult females lay approximately 100 eggs between 6 and 20 days. The eggs are oval-shaped and a white colour. They take 6 to 10 days to hatch.

When the larva emerges, it perforates the stored products causing damage to the tobacco and infesting it. Larvae reach their maximum growth in 30 to 50 days, then enter into pupal stage which lasts for 8 to 10 days or even more, depending on the temperature. The pupae are covered with a silky cocoon that contains food.

The growth period from egg to adult is variable, but it usually lasts between 6 and 8 weeks under the favourable conditions of humidity and temperature (20-37 OC). Lasioderma serricorne cannot tolerate cold weather, the adults die within 6 days if the temperature is 4 OC and the eggs only survive for 5 days at temperatures from 0 to 5 OC.

DETECTION AND MONITORING

Place 1 to 3 traps in each warehouse room, separated at least 5 m apart from each other. The traps must be active all year round in warehouses where tobacco products are stored.


MASS TRAPPING

The males of this species are captured in order to reduce mating, meaning that the unfertilised females will lay unviable eggs. This greatly reduces the population of the pest.

For mass trapping, the number of traps must be increased up to 4 traps per 100 m2 of warehouse and separated at least 5 m apart from each other.


NECESSARY MATERIAL

ECONEX LASIODERMA TRAP and a pheromone diffuser ECONEX LASIODERMA SERRICORNE (40 days) , which lasts for 40 days in field conditions.

The ECONEX LASIODERMA trap consists of a white adhesive sheet, 0.3 mm thick and made of PET. This sheet is coated on its inner side with a pressure-sensitive adhesive (without solvents), which is protected by a sheet of silicone paper. It is used to trap Lasioderma serricorne insects.

The trap is provided unfolded, measuring 40 x 12.5 cm. Once folded, it is prism-shaped and measures 12 x 10.5 x 13 cm.

The trap does not include the pheromone diffuser.

Assembly of the trap: Fold the trap along the guidelines, without inserting the upper tab. Remove the sheet of silicone paper. Insert the upper tab into the grooves of the trap and adjust it to fit.

Pheromone diffuser placed on the base of the trap

Activation of the trap: Place the pheromone diffuser ECONEX LASIODERMA SERRICORNE on the base of the trap, where it will remain fixed by the glue. The trap should be placed on the ground and preferably close to a wall.

DAMAGES

Lasioderma serricorne causes serious damage to tobacco products. Adults and larvae can easily perforate the thick packaging of stored products and cause damage by infesting the tobacco.
