Study on the Hymenoptera parasitoid associated with Lepidoptera larvae in reforestation and agrosilvopastoral systems at Fazenda Canchim (Embrapa Pecuária Sudeste) São Carlos, SP, Brazil

Abstract

The aim of this study was to characterize the local fauna of Hymenoptera parasitoids associated with Lepidoptera larvae in areas of reforestation and agrosilvopastoral systems at Fazenda Canchim (Embrapa Pecuária Sudeste, São Carlos, SP, Brazil). Lepidoptera larvae collected with entomological umbrella were kept in the laboratory until emergence of adults or their parasitoids. From those collected in the agrosilvopastoral system, emerged 267 specimens of hymenopteran parasitoids belonging to 16 genera: Braconidae, Agathidinae (Alabagrus), Braconinae (Bracon), Microgastrinae (Cotesia, Diolcogaster, Glyptapanteles, Pholetesor and Protapanteles), Orgilinae (Orgilus); Ichneumonidae, Campopleginae (Casinaria, Charops and Microcharops); Chalcididae, Chalcidinae (Brachymeria and Conura); Eulophidae, Entedoninae (Horismenus), Eulophinae (Elachertus and Euplectrus). From the Lepidoptera larvae collected in the reforestation, emerged 68 specimens of hymenopteran parasitoids, belonging to 8 genera: Chalcididae, Chalcidinae (Conura); Ichneumonidae, Pimplinae (Neotheronia), Campopleginae (Charops and Microcharops) and Braconidae, Microgastrinae (Apanteles, Diolcogaster, Distatrix, Glyptapanteles and Protapanteles). The results of this study suggest the occurrence of a wide variety of Hymenoptera parasitoids in the studied environments.

Parasitoids diversity in organic Sweet Pepper (Capsicum annuum) associated with Basil (Ocimum basilicum) and Marigold (Tagetes erecta )

“…In the same way, the association with marigold provided an parasitoids increasing (130 individuals), as also found in plantations of onion (Silveira et al, 2009), garlic (Silva et al, 2012), lettuce (Haro, 2015), and kale (Silva et al 2016). Numerous past studies support that vegetable diversification increases the number of parasitoid looking for food, host, and shelter (Pereira et al, 2015).…”

Diolcogaster choi sp. nov. from Brazil, a new gregarious microgastrine parasitoid wasp (Hymenoptera: Braconidae) reared from Hypercompe cunigunda (Lepidoptera: Erebidae) in Brazil

“…The genus Diolcogaster belongs to the subfamily Microgastrinae (Hymenoptera: Braconidae) which comprises 2,700+ described species (Yu et al, 2016;Whitfield et al, 2018) and many thousands of additional undescribed ones (Rodriguez et al, 2013;Fernández-Triana and Boudreault, 2016;Fernández-Triana and van Atcherberg, 2017;Moghaddam and Mokhtari, 2017;. Microgastrinae is the single most important group of parasitoid wasps attacking caterpillars (Whitfield, 1997;Avila et al, 2013;Fernández-Triana et al, 2014;Pereira et al, 2015;Fiaboe et al, 2017), with many species used or being considered as biocontrol agents against lepidopteran pests in agriculture and forestry (Yeargan and Braman, 1986;Smith et al, 2013;Pinto et al, 2014). Diolcogaster is currently the seventh largest genus of Microgastrinae, with 101 species described worldwide (Zeng et al, 2011;Fernández-Triana, 2015;Fernández-Triana et al, 2016;Moghaddam et al, 2019) and hundreds awaiting description.…”

Trichospilus diatraeae (Hymenoptera: Eulophidae): development and reproduction in Lepidoptera palm oil pests

“…(Lepidoptera: Nymphalidae) larvae and pupae in the coconut (Cocus nucifera) (Marcicano et al, 2007(Marcicano et al, , 2009 and oil palm (E. guineensis) (Tinôco et al, 2012) culture. This shows the importance of manipulating natural enemies to increase the biological control (Dobbs and Potter, 2016;Pereira et al, 2015;Smith et al, 2015).…”
