Abstract Harmonia axyridis is an exotic species that can cause serious impacts on native biodiversity in areas where it is introduced to act as a biological control agent. This predator is often involved with intraguild predation, in most cases with aphids predators. Here, we report the results of experiments designed to understand the outcome of the invasion of H. axyridis on native coccinellid aphidophagous guilds using intraguild predation as a theoretical framework. Tests were conducted to determine the interactions between 1st and 4th instars larvae and H. axyridis adults, with Cycloneda sanguinea, Cycloneda pulchella, Eriopis connexa and Hippodamia convergens larvae, as well as eggs predation rate. Two treatments were used: absence and presence of food, Cinara atlantica. The results showed that 1st and 4th instars larvae and H. axyridis adults are able to prey on larvae and eggs of four Coccinellidae species analyzed, and also their own eggs, showing that this exotic species is a dominant predator in this guild of aphidophagous coccinellids. Adding to these results, studies are recommended, especially the monitoring of these species in the field in the long run, reporting their abundance and diversity as well as their behavior and impact within aphidophagous guilds, especially in Coccinellidae species.

ABSTRACT A list of the Coleoptera of importance from Brazil, based on published records was compiled. The checklist contains 345 species of 16 families allocated to 16 states of the country. In addition, three species of two families are registered for the first time. The fauna of Coleoptera of forensic importance is still not entirely known and future collection efforts and taxonomic reviews could increase the number of known species considerably in the near future.

Harmonia axyridis foi detectada pela primeira vez no Brasil em 2002. A partir daí, então tem sido observada do sul ao centro-oeste do País. Até agora, quase todos os casos registrados foram associados com a presença de afídeos, sua principal fonte de alimento. Devido à ocorrência dessa espécie em áreas de cultivo de frutas no Sul e no Sudeste do Brasil, o objetivo deste trabalho foi analisar a preferência e a utilização de três diferentes cultivares de frutas. Os testes foram realizados a 25ºC±1ºC, UR 70% ± 10%, e fotofase de 12 h e com maçãs (Gala e Fuji), uvas (Niágara e Rubi), e peras (Williams e Asiática). Nos testes com frutas não danificadas, os insetos não causaram nenhum dano perceptível. Nos testes com frutas danificadas e não danificadas, uma porcentagem maior e estatisticamente significante de adultos de H. axyridis foi observada nas três frutas danificadas. Nos testes de preferência, a uva Niágara, a maçã Gala e a pera Williams foram significativamente preferidas pelos adultos de H. axyridis. Esses resultados poderão auxiliar no manejo desse inseto, evitando danos, os quais têm sido observados em outros locais onde H. axyridis foi introduzida.

Harmonia axyridis was detected for the first time in Brazil in 2002. Since then, it has been recorded from the South to the Midwest of the country. Until now, almost all the registered cases were associated with the presence of aphids, its preferred source of food. Due to the occurrence of this species in areas of fruit growing in the South and Southeast of Brazil, the aim of this study was to analyze the preference and use of three different cultivars of fruit. The tests were set at 25ºC ± 1ºC, RH 70% ± 10%, and in a photophase of 12 h and with apples (Gala and Fuji), grapes (Niágara and Rubi), and pears (Williams and Asian). In the undamaged fruit experiment, the insects did not cause any noticeable damage. In the damaged and undamaged fruit experiment, a higher and statistically significant percentage of H. axyridis adults were found in the three damaged fruits. In the different cultivar experiment the Niágara grape, the Gala apple, and the Williams pear were significantly preferred by H. axyridis adults. These results may help in the management of this insect, preventing damage, which have been observed in other places where H. axyridis was introduced.

A fauna de Coleoptera de importância forense foi analisada na Reserva Ducke, Manaus, Brasil, durante a decomposição de carcaça de Sus scrofa Linnaeus, 1758. Foram coletadas 41 espécies, pertencentes a seis famílias e 11 subfamílias. Staphylinidae apresentou a maior riqueza com 17 espécies, seguida por Histeridae, com 11 e Scarabaeidae com nove espécies. Euspilotus azureus (Sahlberg, 1823) (Histeridae), Aleochara sp. (Staphylinidae) e Oxelytrum cayennense (Stürm, 1826) (Silphidae) ocorreram em todos os estágios de decomposição. Omalodes lucidus Erichson, 1824 e Scapomegas auritus Marseul, 1855 (Histeridae) são registrados pela primeira vez na Amazônia, sendo também a primeira amostragem na qual essas espécies são encontradas em carcaça em decomposição. A fauna difere das de outras regiões do Brasil, ressaltando a importância de estudos regionais para posterior utilização como provas forenses.

The Coleoptera fauna of forensic importance associated with Sus scrofa Linnaeus, 1758 carcass decomposition in Ducke Reserve, Manaus, Brazil, was determined. A total of 41 species, belonging to six families and 11 subfamilies were collected. Staphylinidae presented the higher richness with 17 species sampled, followed by Histeridae, with 11 and Scarabaeidae with nine species. Euspilotus azureus (Sahlberg, 1823) (Histeridae), Aleochara sp. (Staphylinidae) and Oxelytrum cayennense (Stürm, 1826) (Silphidae) occurred in all stages of decomposition. Omalodes lucidus Erichson, 1824 and Scapomegas auritus Marseul, 1855 (Histeridae) are recorded for the first time in the Amazon, being also reported for the first time associated with a decomposing carcass. The fauna differs from those of other Brazilian regions, emphasizing the importance of studies to determine the regional insect fauna of forensic importance that can be used in criminal investigations.

Este trabalho visou levantar a fauna de Coleoptera associada à carcaça de Sus scrofa L.,1758, espécie utilizada como modelo em Entomologia Forense. O acréscimo ou a substituição seqüencial das espécies de insetos pode ser utilizado para estimar o intervalo post mortem (IPM). O experimento foi realizado no Centro Politécnico (UFPR), de setembro de 2005 a setembro de 2006. A cada estação foi sacrificado um suíno de 15 kg no local, colocado em gaiola. A captura dos insetos foi realizada diariamente em bandeja posicionada abaixo da carcaça e em armadilha tipo Shannon modificada, e a cada 14 dias em cinco armadilhas do tipo pit-fall. Foram coletados 4.360 Coleoptera, pertencentes a 112 espécies de 26 famílias, 12 consideradas de importância forense. A coleta ativa realizada na bandeja foi responsável pela maior captura (2.023 espécimes), seguida pela armadilha Shannon modificada (2.016 espécimes) e por último pelas do tipo pit-fall (324 espécimes). Staphylinidae foi mais coletada na bandeja e Shannon modificada, e Silphidae na armadilha pit-fall. Os principais hábitos encontrados foram predador/parasita (55%)e onívoro (38,05%), com poucas espécies consideradas necrófagas (1,31%).

This paper sought to assess the Coleoptera fauna associated with carcasses of Sus scrofa L., 1758, which is usually used as model in Forensic Entomology. The addition and sequential substitution of insect species could be used to estimate the post mortem interval (PMI). The present study took place in Centro Politécnico (UFPR), between september 2005 to september 2006. A pig weighting 15 kg was sacrificed each season and put inside a cage. Sampling is made daily in a tray placed below the carcass and in a Shannon modified trap, and each 14 days in five pit-fall traps. 4,360 beetles were collected, belonging to 112 species of 26 families, 12 were considered of forensic potential. The active collecting made in the tray was responsible for the largest number of beetles (2,023 specimens), followed by the modified Shannon trap (2,016 specimens) and by the pit-fall traps (324 specimens). Staphylinidae was more abundant in the modified Shannon trap, while Silphidae was more abundant in pit-fall traps. The main habits found are predator/parasite (55%) and omnivorous (38,05%), with only a few species considered necrophagous (1,31%).
