Trichogramma atopovirilia
Oatman & Platner, 1983
Diagnosis
. Genital capsule broad; volsellae swollen, with accentuated lateral constriction; tubular ventral processes joined to intervolsellar process, dorsal ridge undeveloped (dorsal view) on midline of genital capsule; dorsal lamina short, with no distinct posterior extension.
Comments
. This species is similar to
T. acacioi
, as both species have a similar genital-capsule shape; in
T. atopovirilia
, the volsellae are strongly constricted apically and have tubular ventral processes. According to
Zucchi & Monteiro (1977)
,
T. caiaposi
Brun, Moraes & Soares
is a junior synonym of
T. atopovirilia
.
Type repository
. National Museum of Natural History, Washington, D.C. (holotype and paratypes).
Type locality
. Sololá, Guatemala.
Distribution in South America.
Argentina, Brazil, Colombia and Venezuela.
Hosts
. This species has been recorded from seven different hosts, mostly lepidopterans of economic importance (
Zucchi
et al
. 2010
). It was first reared from parasitized
Vanessa
sp. eggs (
Lepidoptera
:
Nymphalidae
) on a species of
Malvaceae
from Guatemala. It was recorded on
Helicoverpa zea
and
Spodoptera frugiperda
in corn fields in Brazil (
Zucchi & Monteiro 1994
).
Trichogramma atopovirilia
has also been reared on factitious hosts, for biological control of the fall armyworm
Spodoptera frugiperda
(J.E. Smith, 1797)
(
Lepidoptera
:
Noctuidae
) (
Morales
et al
. 2004
;
Melo
et al
. 2007
;
Dias
et al
. 2010
). In Brazil,
Anagasta kuehniella
(Zeller)
and
Corcyra cephalonica
(Stainton)
(
Lepidoptera
:
Pyralidae
) have been shown to be the most suitable factitious hosts for mass rearing (
Parra
et al
. 2015
).
