Psyllaephagus trioziphagus (Hymenoptera: Encyrtidae), parasitoide de Mastigimas anjosi (Hemiptera: Calophyidae)

Abstract

<p class="Default"><em><span>Psyllaephagus trioziphagus </span></em><span>(Howard, 1885) foi observado pela primeira vez parasitando imaturos de <em>Mastigimas anjosi </em>Burckhardt et al., 2011, com apenas um parasitoide em cada imaturo. Este parasitoide foi previamente reportado desde o Canadá até o Brasil. Apesar de não ser hospedeiro específico, pode representar um agente útil no controle de <em>M. anjosi </em>no Brasil.</span></p>

Detection and estimation of Mastigimas anjosi (Hemiptera: Calophyidae) populations on Cedrela fissilis trees

“…In addition, diurnal insects respond to energy in the visible spectrum range from 350 to 650 nm, as observed for the black bean aphid, Aphis fabae Scopoli, 1763, the cabbage aphid, Brevicoryne brassicae L., 1758 and the green peach aphid, Myzus persicae Sulzer, 1776 (Hemiptera: Aphididae) in a laboratory in England [ 44 ]. The greater number of nymphs than adults collected may be due to the direct collections of the first on the leaves in groups as a defensive behaviour against natural enemies [ 1 , 45 ]. The greater numbers of M. anjosi nymphs and adults in the autumn confirm the effect of climatic conditions on the capture of hemipterans, as reported for the highest number of individuals of sharpshooters, Acrogonia citrina Marucci & Cavichioli, 2002, Bucephalogonia xanthophis Berg, 1879 and Dilobopterus costalimai Young, 1977 (Hemiptera: Cicadellidae) during periods of high rainfall (207.8 mm) in November 2003 in Viçosa, state of Minas Gerais, Brazil [ 46 ].…”

Atopozelus opsimus (Hemiptera: Reduviidae) Preying on Mastigimas anjosi (Hemiptera: Calophyidae), a Pest of Tropical Cedar, Cedrela fissilis (Meliaceae)

“…Roem., since 2010 (Burckhardt et al 2011). Damage by this insect may cause chlorosis, deformation, curling, spotting, necrosis, abscission, and production of sooty mold on the leaves (Costa et al 2015). Chemical control of this insect has been conducted in T. ciliata plantations (De Queiroz et al 2013), but sustainable alternatives, such as biological control strategies, should be developed and used.…”

“…Syrphid predators (De Queiroz et al 2013) and the parasitoid Psyllaephagus trioziphagus (Howard) (Hymenoptera: Encyrtidae) (Costa et al 2015) are known to be natural enemies of M. anjosi. The objective of this work was to report, for the first time, Atopozelus opsimus Elkins (Hemiptera: Reduviidae) preying on M. anjosi nymphs and adults on C. fissilis trees in Minas Gerais State, Brazil.…”

The Native PsyllidMastigimas anjosi(Hemiptera: Calophyidae): First Record and Abundance on Pink Cedar,Cedrela fissilis(Meliaceae), Trees in São Paulo, Brazil

“…var. australis (Meliaceae) in Brazil (Burckhardt et al 2011) causing rolling, deformation of the leaves, chlorosis, spotting, and necrosis of the foliage (Costa et al 2015).…”

“…We observed Cycloneda sanguinea L. (Coleoptera: Coccinellidae) larvae and Atopozelus opsimus Elkins (Hemiptera: Heteroptera: Reduviidae) nymphs and adults preying on immatures of M. anjosi on C. fissilis leaflets. In addition, flower fly larvae (Diptera: Syrphidae) and lacewing (Neuroptera: Chrysopidae) eggs and adults were observed near the colonies of this psyllid on T. ciliata trees in Minas Gerais State, Brazil (Queiroz et al 2013;Costa et al 2015). Psyllaephagus trioziphagus Howard (Hymenoptera: Encyrtidae) has been observed to parasitize immature M. anjosi and, although not a specific parasitoid, was reported as a possible control agent of this pest in Brazil (Costa et al 2015).…”
