| description | Piezodorus guildinii Westwood and
Nezara viridula (L.) (Hemiptera: Pentatomidae)
are important soybean pests. P. guildinii causes
more injury and is less susceptible to insecticides
compared to N. viridula. N. viridula egg parasitoids
are well studied; however, little is known about
parasitoids of P. guildinii. Alfalfa, soybean
and red clover were sampled during several
seasons to characterize the abundance of both
stink bugs, to determine their egg parasitoids,
and to estimate parasitoids impact. In the field,
Telenomus podisi (Ashmead),Trissolcus urichi
(Crawford) and Trissolcus basalis (Wollaston)
(Hymenoptera: Platygastridae) emerged from
P. guildinii, while only T. basalis (Wollaston)
(Hymenoptera: Platygastridae) emerged from
N. viridula. The proportions of parasitized eggs
(i. e., the parasitoid impact) and egg masses,
as well as the number of parasitized eggs/total
number of eggs of the parasitized egg masses,
were similar for alfalfa and soybean. Parasitism
was not observed in red pclover. Parasitoid
impact was lower during the dry growing
seasons. Although P. guildinii field parasitism
by T. urichi was less significant, laboratory
experiments from the bibliography indicate that
this wasp species performs well on this host.
Trissolcus urichi would be an important biological
control agent against P. guildinii, principally when
the stink bug is more abundant.

(Hemiptera: Pentatomidae) son importantes plagas en soja. P. guildinii causa mayores daños y es menos susceptible a los insecticidas. Los parasitoides oófagos de N. viridula fueron ampliamente estudiados, pero poco se conoce sobre los de P. guildinii. Se muestreó alfalfa, soja y trébol rojo durante varias temporadas para caracterizar la abundancia de ambas chinches, identificar sus parasitoides y estimar el impacto de los mismos. Telenomus podisi (Ashmead), Trissolcus urichi (Crawford) y Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae) emergieron de P. guildinii, mientras que solo T. basalis (Wollaston) (Hymenoptera: Platygastridae) emergió de N. viridula. Las proporciones de huevos (impacto del parasitoide) y de posturas parasitadas, y el número de huevos parasitados/número total de huevos de las posturas parasitadas, fueron similares para alfalfa y soja. En trébol rojo no se registró parasitismo. El impacto del parasitoide fue menor durante las temporadas secas. Si bien el parasitismo de P. guildinii por T. urichi a campo fue poco significativo, los antecedentes de la bibliografía indican que su desempeño en el laboratorio sobre este hospedador es muy bueno. T. urichi podría ser un potencial agente de control biológico de P. guildinii, principalmente en situaciones de mayor abundancia de la chinche. Fil: Cingolani, María Fernanda.
