“…Furthermore, mown sites may also be unfavourable for certain species due to the altered microclimatic conditions (Gardiner and Hassall, 2009). True bugs and orthopterans usually lay their eggs directly onto plants (Dziock et al, 2011;Martínez et al, 2013). Therefore, cutting the vegetation can directly damage eggs, and also juveniles which have a low mobility and low chance of escape.…”

Grazing and mowing are widely applied management practices in semi-natural grasslands, which are one of the most important habitats for biodiversity conservation in Europe. Due to the decline in extensively grazing livestock numbers, an increasing area of formerly grazed grasslands has being used as mown grasslands. However, we have scarce information on how arthropod assemblages are influenced by mowing in formerly grazed pastures. We assessed the effects of mowing compared to grazing on the species richness, abundance and functional diversity of arthropods in three grassland complexes in Hungary. Since 2005, these salt grasslands have been divided into two management units: extensive grazing management has been continued in one part, while annual late cutting has been established in the other part. In each management unit five sites were sampled. Spiders and ground beetles were sampled using pitfall traps, orthopterans and true bugs were sampled using sweep nets twice before cutting in 2015. In total, the data relating to 12,576 adult individuals of 334 species were analysed using mixed-models. Plant-dwelling true bugs and orthopterans responded more sensitively to mowing than ground-dwelling spiders and ground beetles. Beside the general negative effect of mowing on the species richness and abundance of plant-dwelling arthropods, the shifts in the community weighted mean values of these assemblages suggested the importance of the body size, trophic behaviour and dispersal ability of species in the functional response of these assemblages to the different management regimes. Ground beetles and spiders were rather influenced by the differences in the moisture conditions and vegetation properties. Presumably, strong abiotic stressors such as drought can partly override management effects on ground-dwelling arthropods. The effect of uniform and simultaneous biomass removal on large areas, and the direct mortality caused by mowing was the most disadvantageous for plant-dwelling arthropods. Based on our results, traditional management practices should be prioritized in grassland conservation, as alternative management practices might be less effective in preserving grassland biodiversity.

“…La selección de sitios de oviposición es un proceso jerárquico que opera a varias escalas espaciales, cada una de las cuales provee diferentes claves a las cuales las hembras pueden responder (Vinson, 1976;Visser, 1988;Martínez et al, 2013;Dickins et al, 2013). En nuestro estudio las prefrencias de planta hospedera para alimentación y oviposición por parte de las hembras de T. peregrinus no presentaron una correlación ajustada, lo cual sugiere que diferentes criterios median estos pasos de selección.…”

“…La chinche del eucalipto prefiere oviponer en parches ya colonizados por coespecíficos (Martínez et al, 2017a) en línea con otros estudios en chinches cimicomorfas que han demostrado una atracción de las hembras preñadas a claves inducidas por la presencia de coespecíficos en sus plantas hospederas (Groot et al, 2003;Blackmer et al, 2004). Estos hallazgos brindan evidencia adicional a la existencia de una estrategia común en el infraorden Cimicomorpha (Martínez et al, 2013). Esta preferencia por claves relacionadas a coespecíficos podría explicar la oviposición gregaria y la distribución en parches observada en el campo, dado que la presencia de individuos de la chinche del eucalipto en un cierto parche aumentaría la probabilidad de que hembras adicionales vinieran a oviponer en ese parche.…”

“…In our experiment, 371 out of 556 eggs were laid in direct contact with the lerp, suggesting that the observed preference for lerp‐carrying leaves may be, at least in part, explained by the choice of leaf structural features. Other species in the Heteroptera select plants for oviposition according to particular structural features (Lundgren, ; Martínez et al., ), but in general these preferences have been related to a better offspring performance due to bottom‐up (Lundgren et al., ) or top‐down effects (Udayagiri & Welter, ). Further studies are needed to assess the role of the lerps' physical attributes on oviposition‐site selection by the bronze bug.…”

Oviposition-site selection may be greatly affected by competitive plant-mediated interactions between phytophagous insects but these interactions have been poorly investigated on trees. Here, we evaluated the potential interaction between two invasive pests of Eucalyptus trees, the red gum lerp psyllid, Glycaspis brimblecombei Moore (Hemiptera, Sternorrhyncha: Aphalaridae), and the bronze bug, Thaumastocoris peregrinus Carpintero et Dellap e (Heteroptera: Thaumastocoridae). We assessed the effect of the co-occurrence of G. brimblecombei on the selection of feeding and oviposition sites by T. peregrinus females using dual-choice bioassays. We compared developmental time and survival of the first instar of nymphs reared on healthy Eucalyptus tereticornis Smith (Myrtaceae) leaves and on leaves infested with the lerp psyllid, either with or without lerps (i.e., white conical sweet-tasting structures, secreted during the nymphal stage). Bronze bug females prefer to oviposit on lerp-carrying leaves but we found no difference in feeding preference when compared to healthy leaves. Infestation with the lerp psyllid hampered nymphal performance in terms of developmental time and survival, although the presence of lerps reverted the effect in survival and shortened the duration of the initial instar. These results display an interaction between these two insect species that affects both the oviposition preference of T. peregrinus females and the nymphal performance. Although there seems to be a discrepancy between mother preference and offspring performance, feeding on the lerps may prove beneficial to the offspring under long-term conditions and multiple infestation by other pests and diseases.
