“…The life table has been relevant for understanding the population dynamics of a species (Silveira Neto et al, 1976;Melo et al, 2007;Pratissoli et al, 2007). In the present experiment, the temperature of 24 ºC was the most appropriate for the parameters evaluated on T. galloi.…”

“…The Phytosanitary Pest Management is the establishment of control strategies that involve all the knowledge related to the biological cycle of culture, insect pest and of environmental factors. This kind of pest management involves pest control methods aimed at reducing producer costs over time, optimize production and reduce environmental impacts, mainly through lower use of chemical insecticides (Pratissoli et al, 2007;França et al, 2015).…”

The Neoleucinodes elegantalis is considered one of the main tomato pests, as it directly damages the fruit. The use of the parasitoid Trichogramma galloi in the management of N. elegantalis requires studies for knowledge of parasitoid behavior regarding the pest to be managed. The objective of this research was to evaluate the behavior of T. galloi for the management of N. elegantalis, through thermal requirements and of life table. According to the results, the fetal develop of T. galloi starts when the temperature remains above 8.02 ± 0.2°C and the heat buildup for complete development is of 159.74 ± 3.88°C degree days (DD). The number of generations of T. galloi was estimated to the five largest municipalities from the Espírito Santo state

“…Adequate nutrition for immatures and adults could generate more long-lived individuals (VINSON;BARBOSA, 1987). This is important in the efficiency of biological control, considering that longer-lived adults have greater chances of mating, reproduction and the ability to parasitize a greater number of hosts in the field (PRATISSOLI et al, 2007).…”

The ecological, physiological and behavioral processes of insects are linked to their nutrition. The diet of host insects can modify the development of natural enemies and affect their reproductive performance. The objective of this work was to evaluate the development and reproduction of Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae) parasitizing pupae of Tenebrio molitor Linnaeus, 1785 (Coleoptera: Tenebrionidae) rearing in different diets. Pupae of T. molitor generated in six different diets (wheat bran, cornmeal, pelleted feed for rabbits, and bran, pelleted or crushed feed for laying hens) were individually placed in plastic pots and exposed to parasitism by six females of P. elaeisis during 72 h. The biological variables of P. elaeisis were observed and bromatological analyses were performed with pupae of T. molitor and the diets used. The percentage of parasitism and emergency was 100% in all treatments. There was no difference in the life cycle, the offspring number and longevity of the parasitoid. Pupae of T. molitor obtained from larvae fed with cornmeal were smaller and generated P. elaeisis offspring with low sex ratio and shorter length of the tibia. The T. molitor diet based on cornmeal was not suitable for the reproduction of P. elaeisis in the laboratory.

“…Tais observações também foram registradas por Pratissoli et al (2007), que estudaram as diferentes idades de fêmeas de T. pretiosum sobre ovos de P. xylostella e observaram redução na capacidade de parasitismo dessa espécie. Zago et al (2007) também registraram um decréscimo no parasitismo de Trichogramma pratissolii Querino & Zucchi sobre A. kuehniella e Corcyra cephalonica (Stainton) (Lepidoptera: Pyralidae), em função da idade das fêmeas.…”

Segundo Pratissoli et al (2007), parasitoides mais longevos podem apresentar maior eficiência em campo, uma vez que possuem maior tempo para procurar e parasitar ovos dos seus hospedeiros, contribuindo, assim, para o aumento da sua população e da eficácia no controle de surtos posteriores de pragas. Por outro lado, a capacidade total de parasitismo deve ser conhecida, pois se esta for concentrada nos primeiros dias, não haverá necessidade de indivíduos mais longevos em campo (Dias et al, 2008).…”

Resumo -O objetivo deste trabalho foi avaliar o desempenho de Trichogramma galloi (Hymenoptera: Trichogrammatidae) sobre ovos de Diatraea flavipennella e D. saccharalis (Lepidoptera: Crambidae), assim como as características biológicas do parasitoide em ambos os hospedeiros, e elaborar a tabela de vida de fertilidade. Para isso, foram realizados testes com e sem chance de escolha e bioensaios para avaliar as características biológicas do parasitoide em ambos os hospedeiros. A tabela de vida de fertilidade foi elaborada por meio do parasitismo diário das fêmeas de T. galloi sobre os hospedeiros. Os resultados da percentagem de parasitismo em testes com chance de escolha mostraram uma melhor aceitação por parte de T. galloi quanto a ovos de D. flavipennella. Com relação aos parâmetros biológicos do parasitoide em ambas as espécies, não houve diferença significativa. Resultados da tabela de vida de fertilidade evidenciam que D. flavipennella e D. saccharalis permitem aumento populacional para T. galloi. O parasitoide T. galloi apresenta desempenho satisfatório em ambos os hospedeiros, sendo um potencial agente de controle para essas espécies.Termos para indexação: broca-da-cana-de-açúcar, chance de escolha, controle biológico, parasitoide, tabela de vida. Performance of Trichogramma galloi (Hymenoptera: Trichogrammatidae) on eggs of Diatraea spp. (Lepidoptera: Crambidae)Abstract -The objective of this work was to evaluate the performance of Trichogramma galloi (Hymenoptera: Trichogrammatidae) on eggs of Diatraea flavipennella and D. saccharalis (Lepidoptera: Crambidae), as well as the biological characteristics of the parasitoid in both hosts, and to elaborate the fertility life table. For this, tests with and without choice and bioassays to evaluate the biological characteristics of the parasitoid in both hosts were performed. The fertility life table was developed through daily parasitism of T. galloi females on the hosts. The percentage results of parasitism in free-choice tests showed a better acceptance by T. galloi concerning eggs of D. flavipennella. Regarding the biological parameters of the parasitoid in both species, there was no significant difference. Fertility life table results show that D. flavipennella and D. saccharalis allow population increase for T. galloi. The parasitoid T. galloi has satisfactory performance in both hosts, and is a potential control agent for these species.
