biological quality of Tetrastichus howardi hymenoptera eulophidae reared with tenebrio molitor coleoptera tenebrionidae pupae after cold storage
Florida Entomologist, 2019Co-Authors: Elison Floriano Tiago, Rogerio Hidalgo Barbosa, Fabricio Fagundes Pereira, Samir Oliveira Kassab, Carlos Reinier Garcia Cardoso, Willian Yoshio Sanomia, Helter C Pereira, Rosilda Mmf Silva, José Cola ZanuncioAbstract:The endoparasitoid Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae) can be reared with the alternative host Tenebrio molitor (Linnaeus) (Coleoptera: Tenebrionidae). Host storage at low temperatures can regulate parasitoid production and demand in biological control programs. The life cycle (egg to adult), parasitism and emergence percentage, number of parasitoids emerged per host pupae, sex ratio, and longevity of the T. howardi offspring per T. molitor pupa were evaluated after low temperature storage of this host for different periods, and its immature (pupae) in T. molitor pupae for 5 periods at 10.3 °C. Tenebrio molitor pupae stored at 0.5 ± 0.09 °C and 2.7 ± 0.11 °C for 10 and 20 d, respectively, were adequate to produce T. howardi. The biological characteristics of this parasitoid were better with T. molitor pupae stored at 0.5 ± 0.09 °C and 2.7 ± 0.11 °C for 10 and 20 d. Tetrastichus howardi immature (pupae) can be stored in T. molitor pupae for 10, 20, 30, 60, and 90 d at 10.3 °C, preferably in pupae of this host for 10 d to produce the adults of this parasitoid for biological control programs. These results contribute to overcoming 1 of the difficulties encountered in the mass production of parasitoids. Therefore, the conservation of T. molitor pupae in low temperatures can be used to increment of population of T. howardi in mass production for pest control programs. Resumo O endoparasitoide Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae) pode ser criado com o hospedeiro alternativo Tenebrio molitor (Linnaeus) (Coleoptera: Tenebrionidae). O armazenamento de hospedeiros em baixas temperaturas pode regular a producao e a oferta de parasitoides em programas de controle biologico. O ciclo de vida (ovo a adulto), parasitismo e porcentagem de emergencia, numero de parasitoides emergidos por pupa hospedeira, razao sexual e longevidade de T. howardi por pupa de T. molitor foram avaliados apos o armazenamento em baixa temperatura deste hospedeiro por diferentes periodos e seu imaturo (pupa) em pupas de T. molitor por 5 periodos a 10,3 °C. Pupas de Tenebrio molitor armazenadas a 0,5 ± 0,09 °C e 2,7 ± 0,11 °C por 10 e 20 dias, respectivamente, foram adequadas para producao de T. howardi. As caracteristicas biologicas deste parasitoide foram melhores com pupas de T. molitor armazenadas por 10 e 20 dias. Imaturos (pupas) de T. howardi podem ser armazenados em pupas de T. molitor por 10, 20, 30, 60 e 90 dias a 10,3 °C, preferencialmente em pupas deste hospedeiro por 10 dias para produzir adultos desse parasitoide para programas de controle biologico. Estes resultados contribuem para superar uma das dificuldades encontradas na producao em massa de parasitoides. Portanto, a conservacao de pupas de T. molitor em baixas temperaturas pode ser utilizada para incremento da populacao de T. howardi na producao em massa para programas de controle de pragas.

Semina-ciencias Agrarias, 2016Co-Authors: Harley Nonato De Oliveira, Juliana Simonato, Daniele Fabiana Glaeser, Fabricio Fagundes PereiraAbstract:Helicoverpa armigera e uma praga recentemente identificada no Brasil ocasionando perdas significativas em varias culturas em varias regioes do pais. O controle biologico tem sido relatado como uma das alternativas promissoras para o manejo desta praga. O objetivo deste trabalho foi avaliar o parasitismo de pupas de H. armigera pelos parasitoides Tetrastichus howardi e Trichospilus diatraeae , em laboratorio. Pupas de H. armigera foram individualizadas e expostas ao parasitismo por 15 femeas de Trichospilus diatraeae ou por 15 femeas de Tetrastichus howardi , durante 24 h. Apos este periodo, as pupas permaneceram em observacao ate a emergencia dos parasitoides. As porcentagens de parasitismo de Tetrastichus howardi e Trichospilus diatraeae foram de 100%. Em relacao a emergencia, a porcentagem foi de 100% para Tetrastichus howardi e de 90% para Trichospilus diatraeae. O ciclo de vida de Tetrastichus howardi em pupas de H. armigera foi de 15,0 ± 0,0 dias, enquanto que Trichospilus diatraeae completou o desenvolvimento em 15,90 ± 0,10 dias. O numero de individuos de Tetrastichus howardi e Trichospilus diatraeae emergidos por pupa foi de 669,30 ± 33,47 e 816,11 ± 89,22, e razao sexual de 0,91 ± 0,01 e 0,94 ± 0,01, respectivamente. Os parasitoides Tetrastichus howardi e Trichospilus diatraeae parasitam com sucesso pupas de H. armigera em condicoes de laboratorio, demonstrando que esse pode ser um bom hospedeiro para criacao de ambos os parasitoides. Contudo, estudos mais detalhados da relacao parasitoide-hospedeiro sao necessarios para avaliar a viabilidade de inclusao desses parasitoides em programas de manejo integrados de H. armigera.

parasitism of helicoverpa armigera pupae lepidoptera noctuidae by Tetrastichus howardi and trichospilus diatraeae hymenoptera eulophidae parasitismo de pupas de helicoverpa armigera lepidoptera noctuidae por Tetrastichus howardi e trichospilus diatraeae hymenoptera eulophidae
2016Co-Authors: Harley Nonato De Oliveira, Juliana Simonato, Daniele Fabiana Glaeser, Fabricio Fagundes PereiraAbstract:Helicoverpa armigera is a pest that was recently detected in Brazil, which causes significant losses in various crops in different regions of the country. Biological control has been reported to offer a promising alternative in the management of this pest. Thus, this study evaluated the ability of the parasitoids Tetrastichus howardi and Trichospilus diatraeae to parasitize pupae of H. armigera in the laboratory. H. armigera pupae were individually exposed to 15 female Trichospilus diatraeae or 15 female Tetrastichus howardi for 24 h. The pupae remained under observation until the emergence of parasitoids. Parasitism by both parasitoids was observed in 100% of the pupae. Further, 100% of Tetrastichus howardi and 90% of Trichospilus diatraeae emerged. The life cycle of Tetrastichus howardi parasitizing pupae of H. armigera was 15 ± 0.0 days, while that of Trichospilus diatraeae was 15.90 ± 0.10 days. The numbers of offspring from Tetrastichus howardi and Trichospilus diatraeae were 669.3 ± 33.47 and 816.11 ± 89.22 per pupae, with a sex ratio of 0.91 ± 0.01 and 0.94 ± 0.01, respectively. Tetrastichus howardi and Trichospilus diatraeae were shown to successfully parasitize H. armigera pupae in laboratory conditions, suggesting that this host could be used for rearing both parasitoids. However, further detailed studies of the host-parasitoid relationship are needed to assess the feasibility of including these parasitoids in integrated management programs of H. armigera.

¿Multiplicar Tetrastichus howardi (Hymenoptera: Eulophidae) en la oruga de la seda afecta su biología?
Universidad Nacional de Colombia, 2016Co-Authors: Nahara Gabriela Piñeyro, Fabricio Fagundes Pereira, Felipe Luis Gomes Borges, Camila Rossoni, Antonio De Souza Silva, Samir Oliveira KassabAbstract:La multiplicación sucesiva de parasitoides en hospederos alternativos, puede afectar las características biológicas y comprometer los sistemas de cría masiva de estos. El objetivo de este trabajo fue evaluar la multiplicación de Tetrastichus howardi (Olliff, 1893) (Hymenoptera: Eulophidae) en pupas del hospedero alternativo Bombyx mori (Linnaeus, 1758) (Lepidoptera: Bombycidae), durante tres generaciones. Y si eso afecta su desempeño reproductivo, cuando se cría, posteriormente, en pupas del hospedero natural Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae). Las informaciones obtenidas en este estudio pueden mejorar y facilitar el control biológico de plagas, principalmente, con la utilización de parasitoides, debido a que T. howardi parasita y se desarrolla en pupas de B. mori. De forma general, la multiplicación de T. howardi durante tres generaciones en pupas del hospedero alternativo B. mori no compromete las características biológicas de este parasitoide cuando se multiplica en su hospedero natural D. saccharalis a los efectos de su utilización en programas de control biológico

biological quality of Tetrastichus howardi hymenoptera eulophidae reared with tenebrio molitor coleoptera tenebrionidae pupae after cold storage
Florida Entomologist, 2019Co-Authors: Elison Floriano Tiago, Rogerio Hidalgo Barbosa, Fabricio Fagundes Pereira, Samir Oliveira Kassab, Carlos Reinier Garcia Cardoso, Willian Yoshio Sanomia, Helter C Pereira, Rosilda Mmf Silva, José Cola ZanuncioAbstract:The endoparasitoid Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae) can be reared with the alternative host Tenebrio molitor (Linnaeus) (Coleoptera: Tenebrionidae). Host storage at low temperatures can regulate parasitoid production and demand in biological control programs. The life cycle (egg to adult), parasitism and emergence percentage, number of parasitoids emerged per host pupae, sex ratio, and longevity of the T. howardi offspring per T. molitor pupa were evaluated after low temperature storage of this host for different periods, and its immature (pupae) in T. molitor pupae for 5 periods at 10.3 °C. Tenebrio molitor pupae stored at 0.5 ± 0.09 °C and 2.7 ± 0.11 °C for 10 and 20 d, respectively, were adequate to produce T. howardi. The biological characteristics of this parasitoid were better with T. molitor pupae stored at 0.5 ± 0.09 °C and 2.7 ± 0.11 °C for 10 and 20 d. Tetrastichus howardi immature (pupae) can be stored in T. molitor pupae for 10, 20, 30, 60, and 90 d at 10.3 °C, preferably in pupae of this host for 10 d to produce the adults of this parasitoid for biological control programs. These results contribute to overcoming 1 of the difficulties encountered in the mass production of parasitoids. Therefore, the conservation of T. molitor pupae in low temperatures can be used to increment of population of T. howardi in mass production for pest control programs.

O ciclo de vida (ovo a adulto), parasitismo e porcentagem de emergencia, numero de parasitoides emergidos por pupa hospedeira, razao sexual e longevidade de T. howardi por pupa de T. molitor foram avaliados apos o armazenamento em baixa temperatura deste hospedeiro por diferentes periodos e seu imaturo (pupa) em pupas de T. molitor por 5 periodos a 10,3 °C. Pupas de Tenebrio molitor armazenadas a 0,5 ± 0,09 °C e 2,7 ± 0,11 °C por 10 e 20 dias, respectivamente, foram adequadas para producao de T. howardi. As caracteristicas biologicas deste parasitoide foram melhores com pupas de T. molitor armazenadas por 10 e 20 dias. Imaturos (pupas) de T. howardi podem ser armazenados em pupas de T. molitor por 10, 20, 30, 60 e 90 dias a 10,3 °C, preferencialmente em pupas deste hospedeiro por 10 dias para produzir adultos desse parasitoide para programas de controle biologico. Estes resultados contribuem para superar uma das dificuldades encontradas na producao em massa de parasitoides. Portanto, a conservacao de pupas de T. molitor em baixas temperaturas pode ser utilizada para incremento da populacao de T. howardi na producao em massa para programas de controle de pragas.

Universidad Nacional de Colombia, 2016Co-Authors: Nahara Gabriela Piñeyro, Fabricio Fagundes Pereira, Felipe Luis Gomes Borges, Camila Rossoni, Antonio De Souza Silva, Samir Oliveira KassabAbstract:La multiplicación sucesiva de parasitoides en hospederos alternativos, puede afectar las características biológicas y comprometer los sistemas de cría masiva de estos. El objetivo de este trabajo fue evaluar la multiplicación de Tetrastichus howardi (Olliff, 1893) (Hymenoptera: Eulophidae) en pupas del hospedero alternativo Bombyx mori (Linnaeus, 1758) (Lepidoptera: Bombycidae), durante tres generaciones. Y si eso afecta su desempeño reproductivo, cuando se cría, posteriormente, en pupas del hospedero natural Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae). Las informaciones obtenidas en este estudio pueden mejorar y facilitar el control biológico de plagas, principalmente, con la utilización de parasitoides, debido a que T. howardi parasita y se desarrolla en pupas de B. mori. De forma general, la multiplicación de T. howardi durante tres generaciones en pupas del hospedero alternativo B. mori no compromete las características biológicas de este parasitoide cuando se multiplica en su hospedero natural D. saccharalis a los efectos de su utilización en programas de control biológico

The aim of this study was to evaluate if the multiplication of Tetrastichus howardi (Olliff, 1893) (Hymenoptera: Eulophidae) in pupae of the alternative host Bombyx mori (Linnaeus, 1758) (Lepidoptera: Bombycidae) for three generations, affects its reproductive performance, when are reared, then in pupae of the natural host Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae). The information obtained in this study can improve and facilitate the biological control of pests, mainly with the use of parasitoids, due to the fact that T. howardi parasite and develops into pupae of B. mori. In general, the multiplication of T. howardi for three generations in the alternative host pupae of B. mori does not compromise the biological characteristics of this parasitoid when multiplied in its natural host D. saccharalis to the effects of their use in biological control programs.

parasitism of helicoverpa armigera pupae lepidoptera noctuidae by Tetrastichus howardi and trichospilus diatraeae hymenoptera eulophidae
Semina-ciencias Agrarias, 2016Co-Authors: Harley Nonato De Oliveira, Juliana Simonato, Daniele Fabiana Glaeser, Fabricio Fagundes PereiraAbstract:Helicoverpa armigera e uma praga recentemente identificada no Brasil ocasionando perdas significativas em varias culturas em varias regioes do pais. O controle biologico tem sido relatado como uma das alternativas promissoras para o manejo desta praga. O objetivo deste trabalho foi avaliar o parasitismo de pupas de H. armigera pelos parasitoides Tetrastichus howardi e Trichospilus diatraeae , em laboratorio. Pupas de H. armigera foram individualizadas e expostas ao parasitismo por 15 femeas de Trichospilus diatraeae ou por 15 femeas de Tetrastichus howardi , durante 24 h. Apos este periodo, as pupas permaneceram em observacao ate a emergencia dos parasitoides. As porcentagens de parasitismo de Tetrastichus howardi e Trichospilus diatraeae foram de 100%. Em relacao a emergencia, a porcentagem foi de 100% para Tetrastichus howardi e de 90% para Trichospilus diatraeae. O ciclo de vida de Tetrastichus howardi em pupas de H. armigera foi de 15,0 ± 0,0 dias, enquanto que Trichospilus diatraeae completou o desenvolvimento em 15,90 ± 0,10 dias. O numero de individuos de Tetrastichus howardi e Trichospilus diatraeae emergidos por pupa foi de 669,30 ± 33,47 e 816,11 ± 89,22, e razao sexual de 0,91 ± 0,01 e 0,94 ± 0,01, respectivamente. Os parasitoides Tetrastichus howardi e Trichospilus diatraeae parasitam com sucesso pupas de H. armigera em condicoes de laboratorio, demonstrando que esse pode ser um bom hospedeiro para criacao de ambos os parasitoides. Contudo, estudos mais detalhados da relacao parasitoide-hospedeiro sao necessarios para avaliar a viabilidade de inclusao desses parasitoides em programas de manejo integrados de H. armigera.

parasitism of helicoverpa armigera pupae lepidoptera noctuidae by Tetrastichus howardi and trichospilus diatraeae hymenoptera eulophidae parasitismo de pupas de helicoverpa armigera lepidoptera noctuidae por Tetrastichus howardi e trichospilus diatraeae hymenoptera eulophidae
2016Co-Authors: Harley Nonato De Oliveira, Juliana Simonato, Daniele Fabiana Glaeser, Fabricio Fagundes PereiraAbstract:Helicoverpa armigera is a pest that was recently detected in Brazil, which causes significant losses in various crops in different regions of the country. Biological control has been reported to offer a promising alternative in the management of this pest. Thus, this study evaluated the ability of the parasitoids Tetrastichus howardi and Trichospilus diatraeae to parasitize pupae of H. armigera in the laboratory. H. armigera pupae were individually exposed to 15 female Trichospilus diatraeae or 15 female Tetrastichus howardi for 24 h. The pupae remained under observation until the emergence of parasitoids. Parasitism by both parasitoids was observed in 100% of the pupae. Further, 100% of Tetrastichus howardi and 90% of Trichospilus diatraeae emerged. The life cycle of Tetrastichus howardi parasitizing pupae of H. armigera was 15 ± 0.0 days, while that of Trichospilus diatraeae was 15.90 ± 0.10 days. The numbers of offspring from Tetrastichus howardi and Trichospilus diatraeae were 669.3 ± 33.47 and 816.11 ± 89.22 per pupae, with a sex ratio of 0.91 ± 0.01 and 0.94 ± 0.01, respectively. Tetrastichus howardi and Trichospilus diatraeae were shown to successfully parasitize H. armigera pupae in laboratory conditions, suggesting that this host could be used for rearing both parasitoids. However, further detailed studies of the host-parasitoid relationship are needed to assess the feasibility of including these parasitoids in integrated management programs of H. armigera.
