Sensory gene identification in the transcriptome of the ectoparasitoid Quadrastichus mendeli [PDF]
Scientific Reports, 2021 Sensory genes play a key role in the host location of parasitoids. To date, the sensory genes that regulate parasitoids to locate gall-inducing insects have not been uncovered. An obligate ectoparasitoid, Quadrastichus mendeli Kim & La Salle (Hymenoptera:

First record of the eucalypt gall-wasp Leptocybe invasa (Hymenoptera: Eulophidae) from Uruguay [PDF]
Bosque (Valdivia), 2016 Leptocybe invasa es una plaga forestal de reciente introducción, responsable de importantes pérdidas económicas en plantaciones de Eucalyptus spp. a nivel mundial. El objetivo de este trabajo fue reportar su presencia para Uruguay, aportar datos de distribución y biología. Se observó la presencia de agallas de 2013 a 2015, confirmada en 15 de 35 puntos

Biology, Damage and Parasitoids of Eucalyptus Gall Wasp, Leptocybe invasa Infesting
Proceedings of International Forestry and Environment Symposium, 2014 Leptocybe invasa has been recorded few years back in Sri Lanka from Eucalyptuscamaldulensis plantation in Maragamuwa, where no natural enemies were reported. Recentobservations revealed a decreased gall infestation and hence, the present study was conductedto investigate the biology of L. invasa, its damage to E.

First Record of Leptocybe invasa and Ophelimus maskelli Eucalyptus Gall Wasps in Tunisia [PDF]
, 2010 Two Australian gall wasps were detected for the first time in Tunisia on the foliage of Eucalyptus camaldulensis trees. Leptocybe invasa was detected in 2004, while Ophelimus maskelli in 2006. L. invasa makes galls on petioles, leaf midribs and young branches whereas O. maskelli induces galls on limbs.

Anatomía y morfogénesis de las agallas producidas por Leptocybe invasa en plantas de Eucalyptus
Boletín de la Sociedad Argentina de Botánica, 2015 : Leptocybe invasa o “avispa de la agalla del eucalipto”, es un microhimenóptero gallícola que ovipone en hojas jóvenes de eucaliptos. La planta responde formando agallas, que causan enrollamiento, defoliación y colapso de brotes, afectando seriamente la
