Resumo: | During the parasitism process many factors can lead to host rejection by the parasitoid. Thus, it was evaluated bio-ecological aspects of Trichogramma pretiosum Riley (Hym.: Trichogrammatidae) parasiting Sitotroga cerealella Oliver (Lep.: Gelechiidae) eggs. The study was conducted in free-choice test, alternating parasitized and unparasitized eggs, and no-choice test, using only parasitized eggs. For the parasitism study, mated females of T. pretiosum 12 to 24h-old were used. And, parasitized eggs of S. cerealella 24, 72 and 120h-old were used as host. To evaluate the biological characteristics of T. pretiosum superparasitism, S. cerealella eggs were exposed to the parasitism by one or more parasitoid females aiming oviposition of one or two eggs of the parasitoid per host. The parasitism rejection on 72 e 120h previously parasitized S. cerealella eggs was approximately 100% in relation to the 24h-parasitized eggs (ca. 71.3%). On the other hand, the contact time of the female on 24h-parasitized eggs was around twice longer than on 72 and 120h-parasitized eggs. The offspring produced from single egg laid per host werelarger, exhibited no deformation and greater capacity of parasitism, and in contrast of those produced from two eggs laid per host. We concluded that T. pretiosum exhibited ability inrecognizing eggs previously parasitized and that the superparasitism resulted in reduction of reproductive success of the parasitoid. |

Dessa forma, avaliou-se aspectos comportamentais e biológicos de Trichogramma pretiosum Riley (Hym.: Trichogrammatidae) parasitando ovos de Sitotroga cerealella Oliver (Lep.: Gelechiidae). O estudo foi conduzido com chance de escolha, alternando-se ovos parasitados e não parasitados, e sem chance de escolha, utilizando-se apenas ovos parasitados. Para o parasitismo, foram utilizadas fêmeas acasaladas de T. pretiosum de 12 a 24h de idade. Foram utilizados ovos de S. cerealella com 24, 72 e 120h de parasitados. Para a avaliação das características biológicas em situação de parasitismo e superparasitismo, ovos de S. cerealella foram submetidos a uma ou mais fêmeas de T. pretiosum, possibilitando a oviposição de 1 a 2 ovos do parasitóide por hospedeiro. A porcentagem de rejeição de ovos de S. cerealella com 72 e 120h de parasitados foi de aproximadamente 100% em relação aos ovos com apenas 24h de parasitados (71,3%). Em contrapartida, o tempo de contato da fêmea sobre ovos de 24h deparasitados foi, aproximadamente, duas vezes maior que em ovos com 72 e 120h de parasitados. Os descendentes originados de um único ovo do parasitóide/hospedeiro apresentaram-se todos sem deformações, maiores e com maior capacidade de parasitismo, ao contrário dos descendentes emergidos de dois ovos do parasitóide/hospedeiro. Dessa forma, conclui-se que T. pretiosum apresentou habilidade em reconhecer ovos previamente parasitados e que o superparasitismo resultou em redução do sucesso reprodutivo do parasitóide.Submitted by (edna.saturno@ufrpe.br) on 2016-11-28T12:51:34Z No. of bitstreams: 1 Marciene Dantas Moreira.pdf: 367488 bytes, checksum: 1c62f7268fdd87f4772b0530a6eaab2b (MD5)Made available in DSpace on 2016-11-28T12:51:34Z (GMT).

During the parasitism process many factors can lead to host rejection by the parasitoid. Thus, it was evaluated bio-ecological aspects of Trichogramma pretiosum Riley (Hym.: Trichogrammatidae) parasiting Sitotroga cerealella Oliver (Lep.: Gelechiidae) eggs. The study was conducted in free-choice test, alternating parasitized and unparasitized eggs, and no-choice test, using only parasitized eggs. For the parasitism study, mated females of T. pretiosum 12 to 24h-old were used. And, parasitized eggs of S. cerealella 24, 72 and 120h-old were used as host. To evaluate the biological characteristics of T. pretiosum superparasitism, S. cerealella eggs were exposed to the parasitism by one or more parasitoid females aiming oviposition of one or two eggs of the parasitoid per host. The parasitism rejection on 72 e 120h previously parasitized S. cerealella eggs was approximately 100% in relation to the 24h-parasitized eggs (ca. 71.3%). On the other hand, the contact time of the female on 24h-parasitized eggs was around twice longer than on 72 and 120h-parasitized eggs. The offspring produced from single egg laid per host werelarger, exhibited no deformation and greater capacity of parasitism, and in contrast of those produced from two eggs laid per host. We concluded that T. pretiosum exhibited ability inrecognizing eggs previously parasitized and that the superparasitism resulted in reduction of reproductive success of the parasitoid. |
