The defoliating caterpillars, Opsiph-anes invirae Hübner and Brassolis sophorae L. (Lepidoptera: Nymphalidae), and the crown-leaf borer, Eupalamides cyparissias (Fabricius) (Lepidoptera: Castniidae), affect the develop-ment and productivity of this crop in northern Brazil (Vasquez et al. 2008; Ribeiro et al. 2010). Studies involving control methods of these pests are needed.Trichospilus diatraeae Margabandhu & Che-rian (Hymenoptera: Eulophidae) is a pupal parasitoid of many lepidopteran families, such as Arctiidae (Bennett et al. 1987; Paron & Berti-Filho 2000), Crambidae (Bennett et al. 1987), Oecophoridae (Oliveira et al. 2001), Pieridae (Torres-Bauza 1994), Geometridae (Pereira et al. 2008; Zaché et al. 2010; Pastori et al. 2012), Saturniidae (Pastori et al. 2012), Lymantriidae (Zaché et al. 2011a), Riodinidae (Zaché et al. 2011b), Noctuidae and Nymphalidae (Bennett et al. 1987; Zaché et al. 2012).Female parasitoids must overcome the host’s defensive behavior and immune response (An-drade et al. 2010). These factors can affect the biological characteristics and the host choice of parasitoids (Gross 1993; Völkl & Stadler 1996; Farias & Hopper 1999; Walker & Hoy 2003). The objective of this study was to evaluate the poten-tial parasitism of lepidopteran pests of oil palm by T. diatraeae.Opsiphanes invirae, B. sophorae and E. cypa-rissias pupae were obtained from oil palms in the district of Tailandia, Pará State, Brazil (S 24° 2.04' W 48° 08.02'). Trichospilus diatraeae was reared on Tenebrio molitor L. (Coleoptera: Tenebrionidae) pupae at the Federal University of Viçosa, Viçosa, Minas Gerais State, Brazil, at 25 ± 2 °C, 70 ± 10% RH and 12:12 h L:D (Fa-vero 2009). Originally, T. diatraeae was obtained from Thyrinteina arnobia (Stoll) (Lepidoptera: Geometridae) pupae collected on Eucalyptus cloeziana F. Muell. (Myrtales: Myrtaceae) plants (Pereira et al. 2008).Groups of fifty 2-day old T. diatraeae females were placed inside test tubes (14.5 cm H × 2.0 cm diam) together with one pupa of one of the following hosts: O. invirae, B. sophorae or E. cy-parissias, for 48 h. The tubes were closed with cotton and parasitoids females fed with a drop of pure honey applied with a surgical needle on the wall of the test tubes (Pereira et al. 2009).Trichospilus diatraeae parasitized E. cypa-rissias (Fig. 1A), B. sophorae (Fig. 1B) and O. invirae pupae (Fig. 1C), with parasitism rates of 90%, 100% and 90%, respectively. Releases of this parasitoid may provide an alternative bio-logical control in oil palm crops, where several species of Lepidoptera pests can occur simulta-neously (Ribeiro et al. 2010). However, further studies are needed to assess the mobility and dispersal of T. diatraeae in the field (Zappalà et al. 2012) and determine whether mass release of this parasitoid could interfere with other natu-ral enemies (Charles 2012).Trichospilus diatraeae developed in pupae of O. invirae and B. sophorae. An average of 447.83 ± 51.52 and 669.00 ± 89.62 parasitoid adults/pupa were obtained from these hosts, respec-tively. These results show the potential of this parasitoid to control defoliators and its possible establishment in the field through inoculative releases (Eilenberg et al. 2001). However, T. diatraeae adults did not emerge from E. cypa-rissias pupae probably because of host defense mechanisms (Gross 1993; Pennacchio & Strand 2006). The number of T. diatraeae females (50) per E. cyparissias pupae may have been insuffi-cient to generate the amount of toxins and im-mature individuals required to overcome the host defense mechanism (Zaki et al. 1994; Andrade et al. 2010). Encapsulated parasitoids were found inside dissected pupae of E. cyparissias.Downloaded From: https://bioone.org/journals/Florida-Entomologist on 1/29/2019Terms of Use: https://bioone.org/terms-of-use Scientific Notes 677Trichospilus diatraeae can be reared on pupae of the oil palm defoliator caterpillars, O. invirae and B. sophorae, indicating the potential of this parasitoid for the control of these pests.SUMMARYThe expansion of oil palm (Elaeis guineensis) monoculture may favor insect pests such as the caterpillars of Opsiphanes invirae Hübner, Bras-solis sophorae L. (Lepidoptera: Nymphalidae) and Eupalamides cyparissias (Fabricius) (Lepi-doptera: Castniidae).
