Ecological importance of lepidopteran defoliators on eucalyptus plantations based in faunistic and natural enemy analyses

“…(20 individuals) than Winthemya sp. (two individuals) reinforces the importance of species of that genus as parasitoids of defoliating caterpillars of the Noctuidae, Notodontidae, Saturniidae and Sphingidae families (Gil-Santana et al, 2014) and also E. aberrans, S. violascens and T. arnobia on E. urophylla and E. grandis × E. urophylla plantations (Masson et al, 2017a) and with potential for biological control programs (Tavares et al, 2015).…”

“…Entomofauna surveys in forest plantations include the collection of all possible insect stages with the necessity of rearing immatures until adults, used for their identification via external morphology (Pereira et al, 2001;Pratissoli et al, 2003;Zanuncio et al, 2006). Faunistic analysis and species identification studies provide information on damage potential and the need of control measures (Jactel et al, 2002;Ribeiro et al, 2016;Masson et al, 2017a).…”

Where one species leads, another follows: interspecies processions in tropical caterpillars

“…Alternatively, it is plausible that the relationship is not adaptive, but is an artifact of a shared evolutionary history. The presence of a shared communication mechanism, a common host, largely overlapping ranges (Lemaire 2002, The International Barcode of Life Consortium 2016), and high densities observed for H. metabus (Polar et al 2010, Jourdain et al 2012) and H. nanus (Masson et al 2017), make it conceivable that such interspecific interactions could occur frequently in nature, even if the fitness benefits of the association are negligible.…”

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

“…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).…”
