Palmistichus elaeisis Delvare & LaSalle (Hymenoptera, Eulophidae): a new parasitoid of Dione juno juno (Cramer) (Lepidoptera, Nymphalidae)

Abstract

Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera, Eulophidae) is recorded as parasitoid of Dione juno juno (Cramer, 1779) (Lepidoptera, Nymphalidae) in the State of Rio de Janeiro, Brazil.

Palmistichus elaeisis(Hymenoptera: Eulophidae) Parasitizing Pupae of the Passion Fruit PestAgraulis vanillae vanillae(Lepidoptera: Nymphalidae)

“…The sex ratio of P. elaeisis from A. vanillae vanillae pupae was similar to those recorded from other lepidopteran pupae (Pereira et al 2010a,b;Zanuncio et al 2008). This relative constancy of morphological and life characteristics is due to the generalist behavior of P. elaeisis, which can be reared either with lepidopteran or with coleopteran pupae (Gil-Santana & Tavares 2006;Zanuncio et al 2008).…”

“…The pest Agraulis vanillae vanillae L. (Lepidoptera: Nymphalidae) feeds exclusively on Passiflora (Malpighiales: Passifloraceae) plants (Ross et al 2001), and Palmistichus elaeisis Delvare & La-Salle (Hymenoptera: Eulophidae) was reported to parasitize the pupae of another nymphalid passion fruit pest Dione juno juno Cramer (Lepidoptera: Nymphalidae) (Gil-Santana & Tavares 2006). This gregarious parasitoid has also been reported to parasitize various other lepidopteran species (Gil-Santana & Tavares 2006;Pereira et al 2008;Tavares et al 2012aTavares et al ,b, 2013. Furthermore, it can be reared with Bombyx mori L. (Lepidoptera: Bombycidae) (Pereira et al 2009(Pereira et al , 2010a and Tenebrio molitor L. (Coleoptera: Tenebrionidae) (Zanuncio et al 2008).…”

Chlorantraniliprole impact on survival and progeny quality of the pupa of the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae)

“…2017). Parasitism by P. elaeisis was reported in pupae of different pest species including Eupseudosoma involuta (Sepp) (Lepidoptera: Erebidae), Euselasia eucerus Hewitson (Lepidoptera: Riodinidae) (Delvare and Lasalle), and Dione juno juno (Cramer) (Lepidoptera: Nymphalidae) (Gil-Santana and Tavares 2006). Suitable alternative hosts to rear this natural enemy are the yellow mealworm Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae) (Zanuncio et al .…”

Polistes satan (Hymenoptera: Vespidae) predating Dione juno juno (Lepidoptera: Nymphalidae)

“…This pest is mainly controlled with chemical insecticides that can contaminate food, water, and soil, besides reducing populations of natural enemies and facilitating the emergence of resistant insects (Amatuzzi et al, 2018;Costa et al, 2020). Biological control agents of D. juno juno (e.g., Eulophidae, Formicidae, Pentatomidae, Tachinidae and Vespidae) naturally regulate populations of this defoliating lepidopteran in P. edulis crops (Moreira et al, 1998;Gil-Santana and Tavares, 2006;Murgas et al, 2020). Social wasps forage water, plant fibbers, and protein.…”

“…However, prey handling by social Vespidae varies as Synoeca cyanea Fabricius, 1775 (Hymenoptera: Vespidae) that removed Zaprionus indianus Gupta, 1970 (Diptera: Drosophilidae) larvae from the fruit and macerated it into a food mass, to facilitate feeding (Prezoto and Braga, Herrich Schaeffer, 1844 and Podisus nigrispinus Dallas, 1851 (Hemiptera: Pentatomidae) also fed on D. juno juno caterpillars and pupae in the municipality of Viçosa, State of Minas Gerais, Brazil (Murgas et al, 2020;Moreira et al, 1998). Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae) parasitized pupae of D. juno juno in the State of Rio de Janeiro, Brazil (Gil-Santana and Tavares, 2006) and Chetogena aff. scutellaris (Wulp, 1890) (Diptera: Tachinidae) parasitized pupae of D. juno juno with records of the first interaction of Brachymeria koehleri Blanchard, 1935 (Hymenoptera: Chalcididae) as a hyperparasitoid in Diamantina, State of Minas Gerais, Brazil (Pinheiro et al, 2022).…”
