Se cita por primera vez en la Argentina la presencia de Quadrastichus mendeli Kim & La Salle (Hymenoptera: Eulophidae: Tetrastichinae) asociada a agallas producidas por Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae: Tetrastichinae) en eucaliptos de la provincia de Buenos Aires. Quadrastichus mendeli es originaria de Australia y fue introducida en Israel en el año 2007, para ser utilizada como biocontrolador de la «avispa de la agalla», importante plaga de los cultivos de Eucalyptus.First record of Quadrastichus mendeli (Hymenoptera: Eulophidae: Tetrastichinae) in Argentina associated with galls of Leptocybe invasa (Hymenoptera: Eulophidae: Tetrastichinae)». Quadrastichus mendeli Kim & La Salle (Hymenoptera: Eulophidae: Tetrastichinae) is reported for the first time in Argentina, associated to galls produced by Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae: Tetrastichinae). It was found in Eucalyptus crops in Buenos Aires province. Quadrastichus mendeli is native to Australia and it was introduced into Israel in 2007 to be used as anatural enemy of the eucalyptus gall wasp.Centro de Estudios Parasitológicos y de Vectore

Effect of Poultry Manure-Derived Compost on the Growth of eucalypts spp. Hybrid Clones

Interspecific hybrids of E. grandis &times; E. camaldulensis were generated to widen the plantation area. The aim of this study was to assess root capability and development for six different clones of eucalyptus grown in substrates made with three different composts derived from poultry manure. A factorial design was used to assess the effect of different composts on six growth variables. The analysis detected a greater effect from the genotype than the substrate. E. grandis &times; E. camaldulensis hybrid vegetative propagation was successful in alternative substrates formulated from composted poultry manure. GC8 was the genotype that showed the greatest differences for four the different variables among the substrates, being both the most sensitive and the one with the highest values for all parameters measured. The hybrids&rsquo; vegetative propagation was determined in alternative substrates formulated from poultry manure compost. The physicochemical characteristics of substrates composed of pine bark and sawdust provided adequate conditions for the growth of eucalyptus. GC8 was the genotype most sensitive to the use of different substrates, showing significant differences in the ratio of roots/callus, radicular dry weight, and cutting dry weight. These clones might be a good option for evaluating compost-based substrates for forestry applications
