“…A progênie de T. diatraeae produzida por pupa de D. saccharalis foi afetada pela densidade de fêmeas parasitoides, o que pode estar relacionado com a capacidade de suporte do hospedeiro. A progênie pode variar conforme a espécie hospedeira, como ocorreu com T. diatraeae emergidos de pupas de Thyrinteina arnobia, Hylesia paulex (Pastori et al 2012a) e Spodoptera cosmioides Walker, 1858 (Lepidoptera: Noctuidae) (Zaché et al 2012). Além disso, a produção de progênie pode depender do grau de competição entre irmãos em desenvolvimento dentro de um hospedeiro compartilhado (Riddick 2008), resultando em menor tamanho corporal (Fidgen et al 2000).…”

Density of parasitoid females affects their capacity to develop within the host. The number of Trichospilus diatraeae (Hymenoptera: Eulophidae) females per pupa of Diatraea saccharalis (Lepidoptera: Crambidae) was adjusted to study the effect of parasitoid production in the laboratory. Host pupae were parasitised by females of T. diatraeae at densities of 1:1, 7:1, 14:1, 21:1, 28:1 and 35:1 (parasitoid:host). The females of the parasitoid remained in contact with pupae for 24 h in glass tubes (8.5 × 2.5 cm), packed in a climatic chamber regulated at 25 ± 2ºC, 70 ± 10% relative humidity and light regime of 14 h. The percentage of parasitism and emergence of T. diatraeae on pupae of D. saccharalis was 100% in all parasitoid densities. The length of thr cycle (egg-adult) of Trichospilus diatraeae was 19.25 ± 0.22 days at a density of 1:1 and 17.00 ± 0.00 days at 35:1. The offspring number of T. diatraeae was 106.00 ± 12.38 and 514.67 ± 54.55 individuals per pupa at densities of 1:1 and 35:1, respectively. The sex ratio decreased with increasing density, ranging between 0.97 ± 0.01 and 0.89 ± 0.01 at densities of 1:1 and 35:1, respectively. The percentages of parasitism and emergence of T. diatraeae on pupae of D. saccharalis were not affected by the densities of female parasitoids. The densities of 14 to 21 females of T. diatraeae per pupa of D. saccharalis are suitable for rearing this parasitoid under laboratory conditions.

“…Other studies have focused on the interactions of S. cosmioides with intrinsic defenses of the plants themselves, chemical insecticides and Bt proteins (BERGAMASCO et al, 2013;BERNARDI et al, 2014;BOIÇA Jr. et al 2015;SILVA et al, 2016;MACHADO et al, 2020;QUEIROZ et al, 2020). In addition, several studies have been devoted to studying semiochemicals (BLASSIOLI-MORAES et al, 2016) and interactions with natural enemies, especially parasitoids of eggs, larvae and pupae (GOULART et al, 2011a;2011b;ZACHÉ et al 2012;CABEZAS et al 2013a;FREITAS et al, 2018;.…”

We report for the first time Spodoptera cosmioides (Walker, 1858) (Lepidoptera: Noctuidae) larvae feeding on leaves and causing injuries of up to 50% in hop plants, in the experimental field of the Center for Agroveterinary Sciences, State University of Santa Catarina, municipality of Lages, Santa Catarina, Brazil. This study shows the association of native insects with expanding exotic crops such as hops, and the need for monitoring activity for rational management of these pest insects, which already have several natural enemies in their area of natural occurrence.

“…Among the enemies, we highlight the pupae parasitoid Trichospilus diatraeae Cherian and Margabandhu (Hymenoptera: Eulophidae), of Asian origin and with gregarious behavior (Pastori et al, 2012a). This natural enemy has already been reported by parasitizing pupae of species from eight lepidopteran families, both in agriculture and in planted forests (Biezanko, 1960;Brown, 1992;Bennett et al, 1987;Oliveira et al 2016;Silva et al, 2015;Zaché et al, 2012a;Zaché et al, 2012b).…”

Urban afforestation is a practice used in urban centers. Of the plant species used, Brunfelsia pilosa and B. uniflora are used in most cities. The main pest for B. pilosa and B. uniflora is the lepidopteran Methona themisto which can feed on the leaves of the plant and cause its death. As a solution, biological control with parasitoid insects can be an alternative to chemical means. The present study aimed to investigate if M. themisto can be parasitized by Tichospilus diatraeae. Six pupae of M. themisto were offered to T. diatraeae and exposed to parasitism for 72 hours. The observed parasitism was 66% with 90% of the emergence of adult parasitoids. The parasitoid egg-to-adult life cycle was 18 ± 1 days and an average of 510 ± 91.21 insects emerged per pupa. Each parasitoid consumed an average of 1.13 ± 0.16 mg of pupal content to compete its cycle. The results record for the first time in the literature that M. themisto may be a host of T. diatraeae and consequently applied in biological control programs of this pest.
