Behavior of the combined radial post-feeding larval dispersal of the blowflies Chrysomya megacephala and Chrysomya albiceps (Diptera, Calliphoridae) and implications for forensic entomology BABT
Gomes,Leonardo; Sanches,Marcos Rogério; Von Zuben,Claudio José.
The aims of this work was to study the life stages of Chrysomya megacephala in a circular arena allowing the combined radial post-feeding dispersal from the center of the arena of C. albiceps and C. megacephala larvae. To determine the location of each pupa, the distance from the center, the depth and weight of each pupa formed were analyzed. For the larvae of C. albiceps, females released buried deeper than males, reaching an average depth of 10.74 cm and C. megacephala larvae presented greater average results than C. albiceps for all variables, particularly distance, which was 16.02 cm for this species and 12.30 cm for C. albiceps. C. albiceps larvae preyed on 30 C. megacephala larvae in both experiments. These results could be used in forensic...

Dispersão larval radial pós-alimentar em Lucilia cuprina (Diptera, Calliphoridae): profundidade, peso e distância de enterramento para pupação Iheringia, Sér. Zool.
Gomes,Leonardo; Von Zuben,Claudio José.
Blowflies utilize discrete and ephemeral sites for breeding and larval nutrition. After the exhaustion of food, the larvae begin dispersing to search for sites to pupate or for additional food source, process referred as postfeeding larval dispersal. Some aspects of this process were investigated in Lucilia cuprina (Wiedemann, 1830), utilizing a circular arena to permit the radial dispersion of larvae from the food source in the center. To determine the localization of each pupa, the arena was split into 72 equal sectors from the center. For each pupa, distance from the center of arena, weight and depth were determined. Statistical tests were performed to verify the relation among weight, depth and distance of burying for pupation. It was verified that the...

Efeito do tipo de substrato para pupação na dispersão larval pós-alimentar de Chrysomya albiceps (Diptera, Calliphoridae) Iheringia, Sér. Zool.
Gomes,Leonardo; Gomes,Guilherme; Oliveira,Helena G.; Von Zuben,Claudio J.; Silva,Iracema M. da; Sanches,Marcos R..
As moscas-varejeiras utilizam substratos discretos e efêmeros para posturas dos ovos e para alimentação das larvas. Após a exaustão de recursos, as larvas começam a procurar por um sítio de pupação no habitat ou por mais fonte de alimento adicional (dispersão larval pós-alimentar). No entanto, o tipo de substrato de dispersão pode afetar este processo; assim, procurou-se avaliar o comportamento de dispersão de Chrysomya albiceps (Wiedemann 1819) por meio da localização das pupas em arenas circulares preenchidas com vermiculita, comparando-se com outros estudos feitos em serragem. As arenas foram dividas em 72 setores iguais a partir do centro de dispersão para facilitar a localização das pupas no substrato. A massa, a distância de dispersão do centro de...

Foraging by Polybia (Trichothorax) ignobilis (Hymenoptera, Vespidae) on flies at animal carcasses Rev. Bras. entomol.
Gomes,Leonardo; Gomes,Guilherme; Oliveira,Helena G.; Morlin Junior,José J.; Desuó,Ivan C.; Silva,Iracema M. da; Shima,Sulene N.; Von Zuben,Cláudio J..
Proteins for brood nutrition of social wasps are obtained from many prey, including insects (even bees and other wasps), spiders and bits of decaying meat. After being captured and killed, prey are reduced to a shapeless mass and distributed to the brood. Little is known about the foraging activity, especially on this group. Herein we describe the sequence of foraging behaviours of the social wasp Polybia (Trichothorax) ignobilis for hunting flies (Diptera: Calliphoridae and Muscidae) over pig carcasses. To our knowledge, there are few scientific descriptions of prey foraging behaviour on this species.

Influence of photoperiod on body weight and depth of burrowing in larvae of Chrysomya megacephala (Fabricius) (Diptera, Calliphoridae) and implications for forensic entomology Rev. Bras. entomol.
Gomes,Leonardo; Gomes,Guilherme; Oliveira,Helena Gutierrez; Sanches,Marcos Rogério; Von Zuben,Claudio José.
Blowflies use discrete, ephemeral breeding sites for larval nutrition. After exhaustion of the food supply, the larvae disperse in search of sites to pupate or to seek other sources of food in a process known as post-feeding larval dispersal. In this study, some of the most important aspects of this process were investigated in larvae of the blowflies Chrysomya megacephala exposed to a variety of light: dark (LD) cycles (0:0 h, 12:12 h and 24:0 h) and incubated in tubes covered with vermiculite. For each pupa, the body weight and depth of burrowing were determined. Statistical tests were used to examine the relationship of depth of burrowing and body weight to photoperiod at which burrowing occurred. The study of burial behavior in post-feeding larval...

Interação entre fatores visuais e olfativo em localização de recursos pela mosca-varejeira, Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae), em condições naturais Neotropical Entomology
Gomes,Leonardo; Gomes,Guilherme; Casarin,Fabiana E.; Silva,Iracema M. da; Sanches,Marcos R.; Von Zuben,Claudio J.; Fowler,Harold G..
A interação entre pistas visuais e olfativa na resposta de pouso de Chrysomya megacephala (Fabricius) foi analisada em ambiente natural. Para isso, foram utilizados três círculos planos de cartolina de cor branca, preta e outro com a própria grama (controle) com 30 cm de diâmetro. Os círculos foram divididos em quatro quadrantes e cinco setores circulares, tendo como isca 80 mg de carcaça de peixe e carne moída colocada no centro. Para verificar a interação entre as pistas visuais e a olfativa, foi analisada a relação entre a direção do vento e os setores, os quadrantes e a cor do círculo em que os adultos de C. megacephala pousavam. Na presença dos círculos preto e branco, as moscas pousaram mais próximo do ponto de liberação do odor das iscas quando o...

Occurrence of Hymenoptera on Sus scrofa carcasses during summer and winter seasons in southeastern Brazil Rev. Bras. entomol.
Gomes,Leonardo; Gomes,Guilherme; Oliveira,Helena Gutierrez; Morlin Junior,José Jordan; Desuo,Ivan Cesar; Queiroz,Margareth M. Carvalho; Giannotti,Edilberto; Von Zuben,Cláudio José.
Considerable importance has been given to nest construction and larval food transport to the nest as a precondition for the eusociality of insects. Most adult hymenopterans feed on liquids, although bees and a few wasps may also feed on pollen. Carrion represents an additional source of protein for some species and they will scavenge for dead animals in the wild. This paper aims at analyzing Hymenoptera visitors on a pig carcass during the process of decomposition, in the summer of 2005 and the winter of 2006 in Brazil, and comparing the results with other studies in the Neotropical region. To our knowledge, this is the first study which described the occurence of Agelaia pallipes, Polybia paulista and Scaptotrigona depilis on decomposing carcasses in...

Study of the combined radial post-feeding dispersion of the blowflies Chrysomya megacephala (Fabricius) and C. albiceps (Wiedemann) (Diptera, Calliphoridae) Rev. Bras. entomol.
Gomes,Leonardo; Von Zuben,Claudio José.
Blowflies use discrete and ephemeral substrates to feed their larvae. After they run out of food, the larvae begin to disperse in order to find adequate places for pupation or additional food sources, a process named post-feeding larval dispersion. Some important aspects of this process were studied in a circular arena allowing the combined radial post-feeding dispersion from the center of the arena of C. albiceps and C. megacephala larvae. To determine the location of each pupa, the arena was divided in 72 identical sections starting from the center. The distance from the center, the depth and weight of each pupa were evaluated. Statistical tests were done to verify the relation between weight, depth and distance for pupation. From the total an average of...
