“…However, there are many opportunities to manage the negative impacts of this and other pathogens in plantations. In this regard, breeding, selection and the propagation of resistant genotypes will be amongst the most effective strategies (Wingfield et al 2008;Wingfield et al 2013). …”

Over the past decade, Puccinia psidii, which causes rust on species of Myrtaceae, has spread rapidly to new areas and is now widespread. Quarantine has done little to prevent its movement through America, the Pacific, Africa, and in this report, SouthEast Asia. Puccinia psidii is reported for the first time from Indonesia on two genera of Myrtaceae, namely Eucalyptus and Melaleuca. The identity was confirmed by morphology, a molecular barcode comparison to an epitype specimen, and with a molecular phylogenetic approach. Comparison of seven microsatellite markers revealed that the genotype of the rust in Indonesia is the same as that found in Australia. The potential impacts of P. psidii in South-East Asia to the natural environment and plantation forestry are discussed in light of this first report from the region.

Biology and Rearing of <I>Cleruchoides noackae</I> (Hymenoptera: Mymaridae), an Egg Parasitoid for the Biological Control of <I>Thaumastocoris peregrinus</I> (Hemiptera: Thaumastocoridae)

Cleruchoides noackae Lin and Huber (Hymenoptera: Mymaridae) is a solitary egg parasitoid of Thaumastocoris peregrinus Carpintero and Dellapé (Hemiptera: Thaumastocoridae). The parasitoid was first described in 2009 and its biology and rearing are poorly understood. A key obstacle to the use of C. noackae as a biological control agent has been the ability to consistently rear it under quarantine conditions. This study reports on a series of experiments conducted in quarantine to rear C. noackae and to examine the effects of diet on longevity, per capita reproduction and progeny sex ratio, as well as to determine development time, and preference and suitability of host eggs of different ages.When supplemented with honey solution, the longevity of C. noackae females increased significantly 2 by 2.4 days and that of males by 1.7 days, relative to the unfed adults. Mean per capita reproduction for the honey-fed wasps was 7.7 offspring per female, with progeny sex ratio slightly skewed towards males. Mean percentage parasitism was 32.2 %. Cleruchoides noackae was capable of parasitizing and completing development from oviposition to adult eclosion within 15.7 days in host eggs between zero and five days old. The ability of C. noackae to parasitize a wide range of host egg ages increases the period of vulnerability of T. peregrinus to attack, increasing its potential efficacy as a biological control agent. The methods and results reported here represent a crucial step in the on-going efforts to develop this potential biological control system.

“…By 2006, some 496,000 hectares of productive commercial forestry land in South Africa had been planted to non-native Eucalyptus (Forestry South Africa 2006). This resource is seriously threatened by alien invasive pests and pathogens (Wingfield et al 2008;Wingfield et al 2001). Accidental introductions and impacts of insect pests of trees appear to be increasing due to global trade and travel (Brockerhoff et al 2006;Wingfield et al 2008).…”

DNA bar-coding reveals source and patterns of Thaumastocoris peregrinus invasions in South Africa and South America

et al. 2009

Thaumastocoris peregrinus is a recently introduced invertebrate pest of non-native Eucalyptus plantations in the Southern Hemisphere. It was first reported from South Africa in 2003 and in Argentina in 2005. Since then, populations have grown explosively and it has attained an almost ubiquitous distribution over several regions in South Africa on 26 Eucalyptus species. Here we address three key questions regarding this invasion, namely whether only one species has been introduced, whether there were single or multiple introductions into South
