POWDERPOST BEETLE

Lyctus brunneus (Stephens)

[Coleoptera: Bostrichidae]

Adult: Powderpost beetles are 2-7 mm long. The body is cylindrical to cigar-shaped, dark brown and shiny.

Head: Antennae have 9-11 segments with a well defined 2-segmented club. Compound eyes are large and positioned on the lateral margin of the head. The mouthparts consist of mandibles for chewing with 2/3-segmented maxillary palps and 1/2-segmented labial palps.

Thorax: Two pairs of wings are present. The forewings are hardened into protective covers called elytra. The elytra are not used in flight. The elytra protect the hindwings and serve as a dorsal exoskeleton. The hindwings are membranous, fan-shaped and fold flat over the body when at rest. The pronotum is large and square-shaped. All legs are similar.

Abdomen: Cerci are absent.

Reproduction & Life-cycle:Adult females lay approximately 70 eggs during their life-time. The female bites wood and lays 1-3 eggs in the incision. The eclosion period is 6-15 days. Larvae are white and C-shaped (scarabaeiform) with large spiracles on the 8th abdominal segment. The larval stage is 2 months to 1 year and is dependent on temperature, humidity and the starch in sapwood. Mature larvae tunnel toward the surface of the wood and excavate an oval cell for pupation. The pupal stage is 12-27 days. Adults live 78-300 days.

Distribution: The powderpost beetle is a cosmopolitan pest that was originally endemic to North America.

Pest Status:Lyctus brunneus is a pest on sapwood of unfinished hardwoods, picture frames, bamboo and baskets. Adults and larvae are pests and the larvae require starch for development. Reinfestation of timber is common for this beetle.

"We first used A1 Pest Control a few years ago when we noticed a few termites under a wine barrell in the rear yard of our home. We asked A1 Pest Control Sydney to pay us a visit to have a thorough termite inspection of our home. Bruce and his crew were on time, and very well presented. They explained how they would get rid of the termite infestation using a low toxic method and how their Thermal cameras worked, It worked very well and now we can sleep at night!"

"We have been using Bruce form A1 Pest Control for over 4 years now. We bought our new house on the Hills Area, and moved in. our neighbours had problem with rodents and spiders so they are using A1 next door. I asked them if they could come over and treat our house too, as i didn't want to chase pest around our home. The service was not only effective, but carried out without any smelly fumes that we have experienced in our last house. They solved problem next door and I haven't seen a bug since."

"A1 Pest Control exterminators where great! I'm very happy to say that they solved a bed bug problem that I had after we had visitors from overseas visit us. I would recommend A1 Pest Control to anyone needing a safe and effective treatment of bed bugs"

Amanda Wu

"Bruce solved our commercial pest control problem in Castle Hill. Cockroaches were throughout our factory and they were completely gone after two visits from his exterminators. Just seeing one cockroach can lose us clients. I know now everyhing is ok, and our reputation is intact"
