Resumo: The biological control of the boll weevil in Brazil is realized mostly by insect parasitoids, in which Bracon vulgaris Ashmead, a gregarious larval ectoparasitoid, is the most important biocontrol agent responsible for natural reduction of boll weevil populations in cotton ecosystem in the Northeast of Brazil. Even though it has a major importance in cotton production, there is no much data referring to parasitism of A. grandis by B.vulgaris, such as the effect of age, photoperiod and host availability in the parasitism behavior of this braconid wasp, as well as the morphological mechanisms involved in the parasitoid-host interaction. Therefore, this study investigated the morphological components involved in the success of parasitism of boll weevil by B. vulgaris, and the effects of age, photoperiod and host availability in the parasitism behavior of this natural enemy. Through techniques of scanning electron microscopy that the B. vulgaris ovipositor is a multifunctional structure whose composition and morphology are closely related to the role they play, and the parasitoid’s antennae present four types of sensilla (trichoids, basiconical, coeloconical, and placodes) that act as olfactory and gustatory receptors and or express tactile, therm, and hygro-reception functions. Behavioral tests showed that female five days old, the shortest time to host location occurred 8h after light exposure, when parasitoids were most active searching for the host. In relation to the behavioral repertoire of parasitism, B. vulgaris showed the sequence of following behaviors: host search, static, grooming, host acceptance, oviposition and resting. An associative evaluation of the morphology of sensory structures and behavioral studies allowed the better understanding the high rates of parasitism presented by B. vulgaris on A. grandis.

Entre eles, Bracon vulgaris Ashmead (Hymenoptera: Braconidae), um ectoparasitoide larval, constitui o principal agente biológico responsável pela redução natural das populações do bicudo no agroecossistema algodoeiro no Nordeste brasileiro. Embora possua importância na cotonicultura, são escassos os dados referentes à ação de parasitismo de B.vulgaris sobre Anthonomus grandis Boh. (Coleoptera: Curculionidae) tais como o efeito da idade, fotoperíodo e disponibilidade de hospedeiro no comportamento de parasitismo deste parasitoide, assim como os mecanismos morfológicos envolvidos nesta interação parasitoide/hospedeiro. Deste modo, este estudo avaliou os componentes sensoriais envolvidos no sucesso do parasitismo de B. vulgaris sobre A. grandis, bem como o efeito da idade, fotoperíodo e disponibilidade de hospedeiro no comportamento de parasitismo. Através de técnicas de microscopia eletrônica de varredura foi verificado que o ovipositor de B. vulgaris é um órgão multifuncional cuja morfologia e composição estão intimamente relacionadas às funções que exerce, e suas antenas apresentaram quatro tipos de sensilas (tricóides, basicônicas, coelocônicas e placóides) que atuam como receptores olfativos e gustativos e ou expressam função tátil, termo e de higrorrecepção. Os testes comportamentais, por sua vez, mostraram que fêmeas de B. vulgaris com cinco dias de idades, quando submetidas às densidades de seis e 12 larvas hospedeiras por parasitoide, apresentaram as maiores taxas de parasitismo, sendo que o menor tempo para localização do hospedeiro ocorreu após 8h de exposição à luz, onde os parasitoides se mostraram mais ativos em busca do hospedeiro. Quanto ao repertório comportamental de parasitismo, B. vulgaris apresentou os seguintes eventos comportamentais em sequência: busca, parada, autolimpeza, aceite, oviposição e repouso. Através da avaliação associativa da morfologia das estruturas sensoriais e de estudos comportamentais, foi possível compreender melhor os altos índices de parasitismo apresentados por B. vulgaris sobre A. grandis.Submitted by (edna.saturno@ufrpe.br) on 2016-11-30T13:46:24Z No. of bitstreams: 1 Thiago Jose de Souza Alves.pdf: 713733 bytes, checksum: 897fa22e09fbd143d16a268c4b4fffe9 (MD5)Made available in DSpace on 2016-11-30T13:46:24Z (GMT).

description The biological control of the boll weevil in Brazil is realized mostly by insect parasitoids, in which Bracon vulgaris Ashmead, a gregarious larval ectoparasitoid, is the most important biocontrol agent responsible for natural reduction of boll weevil populations in cotton ecosystem in the Northeast of Brazil. Even though it has a major importance in cotton production, there is no much data referring to parasitism of A. grandis by B.vulgaris, such as the effect of age, photoperiod and host availability in the parasitism behavior of this braconid wasp, as well as the morphological mechanisms involved in the parasitoid-host interaction. Therefore, this study investigated the morphological components involved in the success of parasitism of boll weevil by B. vulgaris, and the effects of age, photoperiod and host availability in the parasitism behavior of this natural enemy. Through techniques of scanning electron microscopy that the B. vulgaris ovipositor is a multifunctional structure whose composition and morphology are closely related to the role they play, and the parasitoid’s antennae present four types of sensilla (trichoids, basiconical, coeloconical, and placodes) that act as olfactory and gustatory receptors and or express tactile, therm, and hygro-reception functions. Behavioral tests showed that female five days old, the shortest time to host location occurred 8h after light exposure, when parasitoids were most active searching for the host. In relation to the behavioral repertoire of parasitism, B. vulgaris showed the sequence of following behaviors: host search, static, grooming, host acceptance, oviposition and resting. An associative evaluation of the morphology of sensory structures and behavioral studies allowed the better understanding the high rates of parasitism presented by B. vulgaris on A. grandis.
