The blue gum chalcid wasp, Leptocybe invasa Fisher & La Salle, 2004 (Hymenoptera: Eulophidae) is a pest native from Australia that causes economical
losses in Eucalyptus plantations. It was first detected in 2011 in Uruguay. Damage resulting from L. invasa galls can be particularly severe in Eucalyptus
nurseries and in young plantations. The use of biological control agents (BCA) and plant resistance have proven valuable tools in keeping L. invasa populations under control worldwide. To date, the bioecology and population dynamics of this pest in Uruguay is unknown. The objective of this work was to study the population fluctuation, distribution and management strategies for L. invasa in Uruguay. We conduct a survey among foresters. Four yellow sticky traps (YST) were distributed in an area of 0.5 ha of Eucalyptus spp. in Tacuarembó and replaced monthly from December 2015 to November 2018. Captures in YST were correlated with temperature and precipitation data. Some genotypes of Eucalyptus grandis, E. benthamii and E. grandis x E. camaldulensis hybrids recorded more damage by L. invasa. Currently, this species distributed mostly in the North and West parts of the country. Captures in YST peaked on February, May and November and was negatively linked to accumulated precipitation. This study provides key data towards the implementation of biological control of L. invasa with Selitrichodes neseri (Hymenoptera: Eulophidae) which is currently ongoing in the country. |

Optimal foraging and optimal oviposition are two major forces leading to plant selection by insect females, but the contribution of these forces to the host-selection process has been little studied for sucking herbivores. We studied feeding and oviposition behavior of a global pest, the bronze bug, Thaumastocoris peregrinus Carpintero & Dellape (Heteroptera: Thaumastocoridae), using dualchoice bioassays to evaluate the preference of females between host species, developmental leaf stage, or prior plant exposure to conspecifics. We assessed the link between these preferences and the performance of the offspring, by comparing survival and developmental time of nymphs reared on the various treatments. Finally, we compared the composition of the leaf wax of healthy and damaged leaves, and tested the effects of leaf wax on female preference behavior. Using healthy adult leaves of Eucalyptus tereticornis Sm. (Myrtaceae) as a reference, we found that females prefer to feed on Eucalyptus
grandisW. Hill ex Maiden and E. tereticornis adult leaves that had been previously damaged by female conspecifics, whereas they reject juvenile leaves of E. tereticornis as food. Females also prefer to oviposit on leaves previously damaged by conspecifics but they rejected E. grandis as oviposition substrate. Nymphal performance varied among leaf treatments, suggesting a correlation with oviposition preference (but not feeding preference). Epicuticular wax extracts from damaged leaves contained
higher concentrations of long-chain, saturated linear alkanes, aldehydes, and alcohols than extracts from undamaged leaves. However, a choice assay failed to demonstrate an oviposition preference based on leaf surface wax chemistry. We discuss these findings in the context of the preference performance relationship.
