“…Essa espécie foi introduzida no Havaí em 1958 (Harris et al, 1982), na Austrália em 1968 (Bornemissza 1976) e, em diferentes etapas no Chile (Zunino & Barbero, 1993), nos Estados Unidos (Blume & Aga 1978;Fincher et al, 1983) e no Brasil (Miranda et al, 1990;Bianchin et al, 1998). A América Central tem sido invadida pelo D. gazella por indivíduos das populações introduzidas inicialmente nos Estados Unidos (Barbero & López-Guerrero, 1992). No Brasil a espécie tem sido estudada para fins de controle biológico de moscas e incorporação de matéria orgânica no solo.…”

RESUMONeste estudo, foi avaliada a invasão da comunidade de Scarabaeinae detritívoros de uma savana amazônica pela espécie africana Digitonthophagus gazella (Fabricius 1787). O estudo foi realizado nas proximidades da vila de Alter do Chão (2º 31' S e 55º 00' W), localizada a aproximadamente 36 km a sudoeste de Santarém, Pará, Brasil. Vinte e duas áreas de savanas de 3,75 ha (250 x 150 m) distribuídas em 30.000 ha foram amostradas, no período de 21 de julho a 13 de agosto de 2003, utilizando 66 armadilhas de queda com três tipos de iscas (fezes bovinas, fezes humanas e carcaças). Foram encontrados indivíduos de D. gazella em quatro das vinte e duas áreas amostradas. Procurou-se explicar a presença da espécie nas áreas de savana através de análises de regressão logística, onde as variáveis explicativas foram: ocorrência de queimada nos últimos seis anos, diversidade e abundância total de Scarabaeidae nativos presentes na área, abundância de Canthon sp.1, (espécie de Scarabaeidae mais abundante na região). Exceto pela abundância total de indivíduos de Scarabaeidae nativos, nenhuma das variáveis bióticas e abióticas tiveram efeito estatisticamente significativo na presença do D. gazella. Estes resultados podem ser explicados por: (a) algum fator ainda não analisado, relacionado à invasão da área pelo D. gazella; (b) Não houve tempo para a dispersão e estabelecimento da espécie em todas as áreas; (c) A comunidade nativa de Scarabaeinae apresenta resistência à invasão pelo D. gazella. PALAVRAS-CHAVE:Amazônia, Ecossistema tropical, Brasil, Invasão biológica. Invasion of intra-Amazonian savannas by the dung beetleDigintonthophagus gazella (Fabricius, 1787) (Insecta: Coleoptera: Scarabaeidae) ABSTRACT This work aimed to verify the invasion of the dung beetles community from intra-Amazonian savanna by the African species Digitonthophagus gazella (Fabricius 1787). The research was carried out near Alter do Chão village (2º 31' S; 55º 00' W), 36 Km Southwest of Santarém, Pará, Brazil. Twenty two areas were sampled, from 21 July to 13 August 2003, using 66 baited pitfall traps (cattle dung, human faeces and carcass bait). D. gazella individuals were found in four of twenty two sampled areas. The presence of the species in the savanna was analysed by a logistic regression, using the occurrence of burnings in the last six years, species richness and abundance of native Scarabaeinae, and abundance of Canthon sp1, (the most abundant species in the region), as explanatory variables. Except for the total abundance of native Scarabaeinae, none of the variables were statistically significant for the presence of D. gazella. Hypothetically, these results were probably due to a non-analysed factor related to the invasibility of the area by D. gazella, or lack of time for the species to disperse and establish in all the areas, or a resistance of native dung beetle community to D. gazella invasion. Nevertheless, there must be a competitive mechanism of invasion resistance bounding the abundance of native species and D. gazella invasi...

The dung beetle fauna of the subfamily Scarabaeinae (Coleoptera: Scarabaeidae) occurring in the Laikipia District of Kenya was surveyed. A total of 79 species were found which are diagnosed, keyed, and known dung preferences discussed. Seven species are new records for Kenya, namely Allogymnopleurus indigaceous, Copris denticulatus, Euoniticellus parvus, Gymnopleurus reichei, Oniticellus egregius, Oniticellus pseudoplanatus and Sisyphus tibialis.

“…Although not introduced by humans to Mexico, from the time of its release in the southeast of the United States, this species has expanded rapidly within Mexico and this expansion has been favoured by the conversion of extensive zones, once covered by tropical forest, to cattle pastures. The very recent publication of an article by BARBERO & LOPEZ- GUERRERO (1992) about 'the expansion of D. gazella in Mexico makes it unnecessary to describe the process here. The first published capture for the Mexican Coastal Plains of the Gulf is from 1981 (LAGO et al 1984), far to the north of our study zone.…”

“…gazella is a species of Indoafrican origin with an exceptional capacity for both dispersal and colonization. It has been used with great success by various agricultural services for the purpose of limiting the accumulation of cow dung (see the recent synthesis and bibliographic references in BARBERO & LOPEZ-GUERRERO 1992). Its great capacity for colonization is the result of its wide tolerance to environmental conditions and its high rate of reproduction (the highest known for a Scarabaeinae species).…”

Daily and seasonal activities of a guild of the coprophagous, burrowing beetle (Coleoptera Scarabaeidae Scarabaeinae) in tropical grassland

Daily and annual activity rhythms of a guild of burrowing beetles (Scarabaeinae) were quantified for beetles found on dung in induced pastures on the Coastal Plains of the Gulf of Mexico in the State of Veracruz, Mexico. Comparing collections from 1991-1992 with those of 1972-1973, a notable difference was observed: the presence of Digitonthophagus gazella (Fabricius 1787). This Indoafrican species has a wide environmental tolerance, and was introduced to Texas in 1972. In the study area it has excluded Onthophagus batesi Howden & Cartwright 1963, from the pasture, which is now only found in marginal habitats.The results of this study allow an interpretation of the coexistence of the species that form the nucleus of the guild as dependent on daily and annual segregation. Differences in the daily pattern of activity, as well as the differences in the yearly activity peaks, tend to decrease competition while allowing different species the possibility of being the first colonizer. Evidence of the role of this segregation in a guild dependent on an ephemeral resource (i.e. dung) is the reduced colonizer success of diurnal and crepuscular-nocturnal species on dung pats which have been on the ground for 12 hr, and therefore have been attacked by species of a group with a different time strategy.
