“…In addition, the egg parasitoid Trichogramma pretiosum (Hymenoptera: Trichogrammatidae) has been released in crops for the control of this pest (CHIAPPINI, 2014). Eulophidae parasitoids, natural enemies of many Lepidoptera, including species in the Noctuidae and Crambidae families, are also promising biological control agents for the control of H. armigera (ANDRADE et al, 2010;PEREIRA et al, 2008;VARGAS et al, 2011).…”

“…In Brazil, Tetrastichus howardi has been recorded as parasitizing the pupae of Diatraea saccharalis (Lepidoptera: Crambidae) in sugarcane (VARGAS et al, 2011) and in corn (CRUZ et al, 2011) and pupae of Plutella xylostella in cabbage (SILVA-TORRES et al, 2010). Moreover, studies have demonstrated the ability of this natural enemy to parasitize and develop in the caterpillar stage of D. saccharalis (VARGAS et al, 2011).…”

“…In Brazil, this species was first reported in pupae of Arctiidae (PARON; BERTI-FILHO, 2000); it has since been reported in Geometridae (PEREIRA et al, 2008) and Pyralidae (MELO et al, 2011). So far, there are no reports to indicate whether Trichospilus diatraeae parasitizes H. armigera under natural conditions.…”

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. Key words: Biological control, insect pests, parasitoid ResumoHelicoverpa armigera é uma praga recentemente identificada no Brasil ocasionando perdas significativas em várias culturas em várias regiões do país. O controle biológico 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 laboratório. Pupas de H. armigera foram individualizadas e expostas ao parasitismo por 15 fêmeas de Trichospilus diatraeae ou por 15 fêmeas de Tetrastichus howardi, durante 24 h. Após este período, as pupas permaneceram em observação até a emergência dos parasitoides. As porcentagens de parasitismo de Tetrastichus howardi e Trichospilus diatraeae foram de 100%.

Resumo -O sucesso de programas de controle biológico com parasitóides depende de pesquisas aplicadas e, por isso, estimouse o número ideal de fêmeas de Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae) para liberação em plantios de eucalipto, visando o controle de lepidópteros desfolhadores. Em cada repetição foram utilizadas trinta e seis pupas do hospedeiro alternativo Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae) com 24 a 48 horas de idade que, foram individualizadas em armadilhas confeccionadas com tela de náilon e fixadas em ramos de plantas de Eucalyptus grandis nos terços superior, médio e inferior, na proporção de 33,33% (12 armadilhas). Após a fixação das armadilhas, as plantas foram cobertas individualmente, com uma gaiola de 7,0 x 7,0 x 2,5 m confeccionada com tecido organza e posteriormente liberadas, 36; 72; 144; 288; 576 ou 1.152 fêmeas de P. elaeisis, representando um, dois, quatro, oito, 16 ou 32 parasitóides por pupa e na testemunha, não houve liberação do parasitóide. Cada proporção foi considerada um tratamento, sendo instaladas seis repetições permitindo o parasitismo por 96 horas. O número de pupas de A. gemmatalis parasitadas foi crescente com o aumento do número de parasitóides liberados, independentemente do terço da planta considerado, ajustando-se a uma função quadrática com ponto de máximo próximo a 25 fêmeas por pupa. Na densidade de 32 fêmeas/pupa não houve aumento significativo no número de pupas parasitadas, sugerindo 25 fêmeas de P. elaeisis por pupa como a densidade mais próxima do ideal para liberação desse parasitóide em plantios de eucalipto.Palavras-chave -Lepidoptera.

Abstract -The success of programs of biological control with parasitoids depends on applied research and therefore it was estimated the optimal number of females Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae) for release in eucalyptus plantations, for the control of lepidopterans defoliators. In each replicate were used thirty-six alternative host pupae of Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae) with 24 to 48 hours old that were identified in traps made of nylon with mesh and fixed in branches of trees of Eucalyptus grandis in thirds upper, middle and bottom, in the proportion of 33.33% (12 traps). After setting the traps, the trees were covered individually with a cage of 7.0 x 7.0 x 2.5 m made with organza fabric and subsequently released, 36; 72; 144, 288; 576 or 1,152 females of P. elaeisis, representing one, two, four, eight, 16 or 32 parasitoids per pupae and for the witness there was no release of the parasitoid. Each proportion was considered a treatment, installed six replicates itself and allowed the parasitism for 96 hours. The number of pupae of A. gemmatalis parasitized increased with the increase of the number of parasitoids released, regardless of the third of the plant considered, adjusting to a quadratic function with point of maximum close to 25 females ...
