This is the first register of Sinoxylon conigerum attacking timber of teak (Tectona grandis L.f.), mango tree (Mangifera indica L.) and (Astronium fraxinifolium Schott) in the municipalities of Cuiabá and Várzea Grande, State of Mato Grosso, Brazil.

Key words: Insecta, teak, auger beetle


A ocorrência de Sinoxylon conigerum Gerstäcker é registrada pela primeira vez no Brasil em madeira de teca (Tectona grandis L.f.), mangueira (Mangifera indica L.) e gonçaleiro (Astronium fraxinifolium Schott), em Cuiabá e Várzea Grande, MT.

Palavras-chave: Insecta, teca, coleobroca



The teak, Tectona grandis L.f., native from the Asian continent, and one of the most valuable timbers in the world wide trade, is presently the main forest crop in the State of Mato Grosso. Its introduction in this State as commercial plantation dates back to almost three decades and several native and introduced pests have been detected since then.

At the end of 2001, adults of Sinoxylon conigerum Gerstäcker were observed attacking logs and cut wood of teak, T. grandis, in the municipality of Várzea Grande, State of Mato Grosso. The insect was identified by Dr. Edson P. Teixeira from the Instituto Agronomico de Campinas and, according to Fisher (1950), this is an African species being Moçambique the type locality. The Brazilian Ministry de Agriculture was notified and authorized the publication of a scientific note.

A survey was carried out with twenty ethanol baited traps, model of Marques-Carrano (Nakano & Leite 2000), in the municipalities of Cuiabá and Várzea Grande, from September 2002 to February 2004. The rainy season (September to March) was the period of highest occurrence of the insect. The family Bostrichidae is composed by xylophagous species attacking trunk and twigs of live trees and wood of dead or falling ones (Carvalho 1971).

Bostrichid species are important pests in silviculture and agriculture, and species of Sinoxylon are particularly important as pests of trees, wood and bamboos (Fisher 1950, Teixeira et al. 2002). S. conigerum is a xylophagous and polyphagous species recorded attacking rubber wood (Hevea brasiliensis Müll.Arg.), pigeon pea (Cajanus cajan (L.) Millsp.), Samanea saman (Jacq.) Merr., mango tree (Mangifera indica L.), cassava stem (Manihot esculenta Crantz), Piptadenia flava (Spreng. ex DC.) Benth., cut branches of Hura crepitans L., cut twigs of Myroxylon balsamum (L.) Harms., fallen trunk of flamboyant [Delonix regia (Bojer) Raf.], cotton dry roots (Gossypium hirsutum L.) branches of guava (Psidium guajava L.), Swietenia mahogani DC., and teak (T. grandis) (Binda & Joly, 1991, Balasubramanya et al. 1990, Tomimura, 1993). Beeson & Bhatia, apud Fischer (1950), registered S. conigerum attacking Adina cordifolia Benth. & Hook.f., Albizzia amra (Roxb.) Boiv., Holoptelea integrifolia (Roxb.) Planch., M. indica, Shorea robusta Gaertn., Terminalia bialata (Roxb.) Steud., Terminalia myriocarpa Van Heurck & Mull. Arg., Grewia tiliaefolia Vahl, and damaging lead cables.

Fisher (1950) examined material intercepted in New York, in Derris sp. roots from the Philippines, barbasco stems from Venezuela, ebony logs from Africa and wooden packing cases from India reported that S. conigerum was not established in America, and commented that this insect is common in India and widespread in the tropics. S. conigerum is a nocturnal species, attracted to light, and is registered attacking the wood of Acacia and roots of cassava from Madagascar (Lesne 1906). S. conigerum is reported occurring in Thailand, Chine, Malaysia, Florida, India, Eastern Africa, Venezuela, Madagasgar, Ceylon, Java, Philippines, Hawaiian Islands and was intercepted in Canada, Italy, New Zealand (not established) and probably should be considered a cosmopolitan species (Fisher 1950, Reichardt 1964, Balasubramanya et al. 1990, Binda & Joly 1991, Poggi et al. 1994, Chen 1995, Ho & Hashim 1997, Canadian Food Inspection Agency 1998, Thomas 1999, Ormsby 2001).

In Brazil, S. conigerum was detected in Cuiabá (15º 35' 46" S and 56º 05'48"W) and Várzea Grande (15º 38'48" S and 56º 07'57"W). In 2002, the second author of this paper identified two specimens of S.conigerum labeled "Bostrichidae – wood material – Brazil – September 2002", sent by the Swedish University of Agricultural Sciences, Dept. of Entomology. These insects were detected in wood pallets imported from Brazil. The use of wood pallets in the international trading activities allows an intense transit of insects, as the material containing S. conigerum intercepted in the Brazilian port of Vitória, State of Espírito Santo, in January and February of 2004, in wood pallets imported from India. These specimens are deposited in the Collection of "Instituto Agronômico de Campinas (IAC)" under numbers 7666 and 7667.

This is the third species of the genus recorded in Brazil; Teixeira et al. (2002) recorded Sinoxylon anale Lesne in Americana, State of São Paulo, and S. senegalense (Karsch) in Natal, State of Rio Grande do Norte. Specimens of S. conigerum are deposited in the Collections of Cuiabá, State of Mato Grosso, the Instituto Agronômico de Campinas (IAC) under the number 7539, and the Faculdade de Agronomia da UNESP - Campus de Ilha Solteira, in Ilha Solteira, State of São Paulo.
