“…Oxydia vesulia Cramer (Lepidoptera: Geometridae) is a native moth observed in population outbreaks, damaging eucalyptus plantations in Brazil (Campos and Cure, 1993;Santos et al, 2002;Oliveira et al, 2003;Zanuncio et al, 2018). This insect has six or seven instars lasting around 27 days for males and 31 for females, and the leaf consumption by its caterpillars increase considerably from the fourth instar (Zanuncio et al, 1993;Espindola and Gonçalves, 2000).…”

Tetrastichus howardi (Hymenoptera: Eulophidae): first report of parasitism in Oxydia vesulia (Lepidoptera: Geometridae)

The adaptation of native lepidopteran species to eucalyptus plantations reduces the productivity of this crop in Brazil. Oxydia vesulia Cramer (Lepidoptera: Geometridae) is a secondary pest, frequently reported in eucalyptus plantations with population outbreaks and economic damages. Methods of biological control of this pest may include the use of the exotic pupae endoparasitoid Tetrastichus howardi Olliff (Hymenoptera: Eulophidae), reported as efficient to controlling lepidopteran pests. The parasitism of O. vesulia caterpillars and pupae by T. howardi was evaluated under controlled conditions (25 ± 1 ºC, 60 ± 20% humidity and 12:12 h L:D). Each O. vesulia caterpillar or pupae was individually placed in a flat-bottom tube with 10 and 15 females of T. howardi for 48h, respectively. The parasitoids were removed after that period, the caterpillars were fed and the pupae were maintained until emergence of the parasitoid or formation of pupae and emergence of adults of this pest. The fourth-instar caterpillars of O. vesulia, after the parasitism period, were kept in pots with Eucalyptus urophylla leaves, changed daily until the end of the experiment. A total of 40% of the caterpillars died before the pre-pupae stage, 40% reached the pupae stage and died due to inadequate adult formation and 20% generated moths, but none adult parasitoid emerged from the caterpillars. All pupae of O. vesulia were parasitized and showed emergence of parasitoids. The parasitism of O. vesulia caterpillars and pupae by T. howardi shows the potential of this natural enemy for the integrated management of this defoliator pest in eucalyptus plantations.

“…Oxydia vesulia female moths live an average of 12 days and can lay 1,970 eggs in up to nine postures (Espíndola and Gonçalves, 2000). This specie is considered a secondary pest and its populations tend to increase with the period of cultivation of eucalyptus in the same area (Zanuncio et al, 2018).…”

“…Eucalyptus trees play an important role in the Brazilian economy. Because they are locally abundant, this type of biomass is used as an energy source in agribusiness (Lenz et al, 2019), but its monoculture can favor the occurrence of pests such as defoliator caterpillars, which must be controlled to reduce their damage (Masson et al, 2017;Munique et al, 2018;Zanuncio et al, 2018).…”

Social Wasps in Exotic Forest Planting and Atlantic Rainforest in the Neotropical Region

et al. 2020

Social wasps play an important role in communities, whether in natural or agricultural ecosystems, performing pollination and/or predation on other organisms, especially caterpillars, which reveals their potential for biological control. We register species of predatory wasps found in a eucalypt reforested area compared with a native rainforest. Five species of social wasps were found: Agelaia myrmecophila (Ducke), Mischocyttarus punctatus (Ducke), Polistes carnifex (Fabricius), Polybia liliacea (Fabricius), and Polybia striata (Fabricius), with higher numbers in the eucalypt monoculture than in the Atlantic rainforest, suggesting no negative impact of the monoculture on the population of that natural enemies.
