Resumo: | Acarophenax lacunatus (Cross & Krantz) (Prostigmata: Acarophenacidae) is a parasitoid mite on eggs of some Insecta; this could be a complementary tool for pest management in stored products. This mite has preference for eggs of Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae) attaching to the adult beetles for dispersion, a phenomenon referred to as phoresy. Behavioral studies are critical for the understanding of several aspects of arthropod biology. No investigation on the parasitism behavior of A. lacunatus on and its phoretic relationship with R. dominica has been conducted yet and thus it was the objective of this work. Two sets of studies were conducted: the first investigated the parasitism behavior of A. lacunatus on the egg of R. dominica, and the second investigated whether phoresy of A. lacunatus would affect flight initiation and if phoretic loads would affected the walking behavior of adult beetles. In the study of parasitism behavior of A. lacunatus, the mite was placed in an arena together with in one host egg and observed until the parasitism. Based on observations of several individuals, the parasitism behavior was described with the following behavioral categories: initial exploratory march, exploratory march after finding the host egg and parasitism. In the test of flight initiation, adults of R. dominica with and without phoretic mites were placed in a bioassay chamber, which was evaluated in 10-min intervals for one hour to verify whether or not there were mites attached to the beetles that initiated flight. Results showed that most beetles initiating flight had no mites attached to their bodies. In the second test involving phoresy, beetles with different phoretic loads (0, 2, 4, 6, 8, 11 and 23 mites/insect) were observed in a video-recorded arena so as to determine the distance walked, time spent walking and time without walking. Beetles with phoretic loads of two, four and six mites walked longer distances and stayed less time without walking unlike beetles with phoretic loads of 11 and 23 mites, which tended to show a walking pattern similar to beetles without phoretic mites. In addition to observing a uniform pattern in the parasitism behavior by A. lacunatus on eggs of R. dominica, the presence of phoretic mites was associated with low frequency of flight initiation by the beetle, and depending on the number of mites attached to coleopteran, walking was stimulated or unaffected. |

Dissertação (Mestrado em Ciência entomológica; Tecnologia entomológica) - Universidade Federal de Viçosa, Viçosa, 2007.http://locus.ufv.br/handle/123456789/3857Acarophenax lacunatus (Cross & Krantz) (Prostigmata: Acarophenacidae) is a parasitoid mite on eggs of some Insecta; this could be a complementary tool for pest management in stored products.

Este ácaro tem preferência por parasitar ovos de Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae), em cujos adultos realiza forésia, forma passiva de deslocamento. Estudos a respeito do comportamento são de fundamental importância para a compreensão de diversos aspectos da biologia de artrópodes; no entanto estudos mais detalhados a respeito do comportamento de parasitismo de A. lacunatus e de sua relação forética com R. dominica ainda são poucos. Desta forma estudou-se o comportamento de parasitismo de A. lacunatus em ovos de R. dominica, bem como sua relação forética com esse coleóptero. Para a realização deste trabalho foram feitos dois ensaios. O primeiro abordou o estudo do comportamento de parasitismo de A. lacunatus em ovos de R. dominica. O segundo ensaio foi realizado em dois testes: um para verificar se a forésia de A. lacunatus afetaria a iniciação de vôo de seu hospedeiro e o outro para averiguar se a carga forética prejudicaria o caminhamento do seu hospedeiro. No estudo do comportamento de parasitismo de A. lacunatus, o ácaro foi colocado em uma arena, juntamente com um ovo hospedeiro, sendo observado até o parasitismo. A partir destas observações, descreveu-se o comportamento de parasitismo com as seguintes categorias comportamentais: marcha exploratória inicial, marcha exploratória após o encontro do ovo e parasitismo propriamente dito. Para o teste da relação entre forésia e iniciação de vôo utilizou-se adultos não-sexados de R. dominica, com e sem ácaros foréticos. Estes coleópteros foram colocados em uma câmara de bioensaio que foi avaliada, em intervalos de 10 minutos, por uma hora, para verificar se os besouros que iniciaram vôo tinham ou não ácaros foréticos. Observou-se que a maior parte dos besouros que iniciaram vôo não tinha ácaros aderidos ao corpo. No teste da relação de cargas foréticas com o caminhamento de R. dominica, besouros contendo diferentes cargas foréticas (0, 2, 4, 6, 8, 11 e 23 ácaros/inseto) foram observados quanto à distância caminhada, ao tempo de caminhamento e o tempo sem caminhar. Besouros com cargas foréticas de dois, quatro e seis ácaros caminharam mais e ficaram menos tempo sem caminhar ao contrário do observado para besouros com cargas foréticas de oito, 11 e 23 ácaros, os quais tenderam a ter um padrão de caminhamento semelhante aos de besouros sem ácaros foréticos. Em conclusão, além de se verificar que há um padrão comportamental uniforme no parasitismo de A. lacunatus sobre ovos de R. dominica, verificou-se que a presença de ácaros foréticos esteve associada à baixa freqüência de iniciação de vôo do besouro, e que, dependendo da densidade de ácaros presos ao coleóptero, o caminhamento parece ser estimulado ou não afetado.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de ViçosaMestrado em EntomologiaUFVBRCiência entomológica; Tecnologia entomológicaÁcaro parasitóideAcarophenacidadeControle biológicoArmazenamento de grãosParasitoid miteAcarophenacidaeBiological controlGrain storageCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADE::ENTOMOLOGIA AGRICOLAComportamento de parasitismo de Acarophenax lacunatus e impacto de sua forésia em Rhyzopertha dominicaParasitism behavior by Acarophenax lacunatus and impact of its phoresy on Rhyzopertha dominicainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf183371https://locus.ufv.br//bitstream/123456789/3857/1/texto%20completo.pdfd1e3f53fdf8243e46cb5663bc7707bdfMD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain69544https://locus.ufv.br//bitstream/123456789/3857/2/texto%20completo.pdf.txtb5aa139b09c72d10eb5906d881158d8bMD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3554https://locus.ufv.br//bitstream/123456789/3857/3/texto%20completo.pdf.jpgf81557c48f2950d4792a7f3ebb03bfa1MD53123456789/38572016-04-09 23:22:18.739oai:locus.ufv.br:123456789/3857Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-10T02:22:18LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |

Acarophenax lacunatus (Cross & Krantz) (Prostigmata: Acarophenacidae) is a parasitoid mite on eggs of some Insecta; this could be a complementary tool for pest management in stored products. This mite has preference for eggs of Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae) attaching to the adult beetles for dispersion, a phenomenon referred to as phoresy. Behavioral studies are critical for the understanding of several aspects of arthropod biology. No investigation on the parasitism behavior of A. lacunatus on and its phoretic relationship with R. dominica has been conducted yet and thus it was the objective of this work. Two sets of studies were conducted: the first investigated the parasitism behavior of A. lacunatus on the egg of R. dominica, and the second investigated whether phoresy of A. lacunatus would affect flight initiation and if phoretic loads would affected the walking behavior of adult beetles. In the study of parasitism behavior of A. lacunatus, the mite was placed in an arena together with in one host egg and observed until the parasitism.
