Batus barbicornis ( Linnaeus, 1764) Coleoptera, Cerambycidae- "toca-viola" ou "serra-pau".

Espécie integrante da família Cerambycidae que reúne cerca de 10.000 espécies nas Américas. O gênero Batus, além de B. barbicornis, contém outras duas espécies que ocorrem nas florestas Amazônica e Atlântica. B. barbicomis habita a Hiléia e suas plantas-hospedeiras e desenvolvimento ontogenético são ainda desconhecidos.

De maneira geral, as larvas de Cerambycidae alimentam-se de madeira e escavam galerias no interior de troncos e ramos. Esse comportamento alimentar determina sérias injúrias ou até mesmo a morte das plantas-hospedeiras.

Os adultos normalmente têm vida efêmera; perecem pouco tempo após a cúpula e a postura, que podem ocorrer alguns dias depois da emergê!ncia. Em contraposição, a vida larval é longa, quase sempre de um ano, podendo prolongar-se a dois ou três.

Se por um lado daninhas às essências florestais e ornamentais e às árvores frutíferas, as larvas de Cerambycidae desempenham papel relevante na reciclagem de nutrientes. Ao se alimentarem nos ramos e troncos caldos viabilizam através de suas galerias a entrada de fungos e bactérias celúloliticos que determinam aceleração na decomposição da matéria vegetal.

Batus barbicornis (Linnaeus, 1764)

Coleoptera Cerambycidae - Wood-boring beetle or "long-horned"

This species belongs to the family Cerambycidae which joins about 10,000 species in Americas. Besides B. barbicornis, the genus Batus comprises two other species which appear in the Amazonian and Atlantic forests. B. barbicornis habitat is Hylea. Host plants and ontogenetic development are still unknown.

Usually Cerambycidae larvae feed upon wood and dig galleries inside trunks and branches. This feeding behavior causes serious injuries or even the death of the host plants.

Adults have generally a short life; they die some days after the copulation and the egg-laying, after the emergence. On the other hand larval life is long, usually one year, but it can be extended to two or three years.

If, on one hand, the Cerambycidae larvae are injurious to forest and ornamental species and to fruit trees, on the other, they are very important agents in the recycling of nutrients. By getting their food from fallen branches and trunks they enable - through the galleries - the entrance of cellulolytic fungi and bacteria which cause acceleration of vegetable matter decomposition.
