“…The results of the present study do not support, nor do they reject the influence of rainfall in psyllid abundance, presumably because there are no distinct periods of rainfall and drought in the study area. A similar situation was observed in other regions where the red gum lerp psyllid has spread (Ferreira Filho et al ., ).…”

1 The red gum lerp psyllid Glycaspis brimblecombei is an invasive insect species, native from Australia, that specifically feeds on Eucalyptus trees. It has invaded several countries throughout the world. In Argentina, it was first recorded in 2005, although little is known about its ecology in the region. 2 We assessed G. brimblecombei population development on Eucalypus camaldulensis and Eucalyptus dunnii using samples of branches for the immature stages and yellow sticky traps for the adults. We also identified the meteorological variables associated with changes in the red gum lerp psyllid abundance. 3 The abundance of eggs, nymphs and adults stages of G. brimblecombei was significantly greater on E. camaldulensis than on E. dunnii in the 2 years of the survey. 4 Glycaspis brimblecombei development was complete on E. camaldulensis where all instars were present, even in the unfavourable seasons. The full development of the psyllid population was not observed in E. dunnii where a high mortality of the first and second nymphal instars was detected. 5 Temperature and relative humidity were the variables that mostly affected red gum lerp psyllid abundance, whereas no effect of rainfall was detected.

“…Climate conditions influence the growth rate; high temperatures without rainfall break down the populations, but are not enough to minimize damage. The effects of high temperatures were also evaluated in Brazil (Ferreira-Filho et al 2008), where no influence of rainfall was found on population dynamics, because, as pointed out by the authors, during the observations there were no distinct periods of rainfall and drought. Regarding the effects of the rainfall, Oliveira et al (2012), with an experimental test conducted on seedlings of E. camaldulensis, have proven the effects of artificial rain in reducing the abundance of lerps through solution and mechanical removal by water.…”

“…In particular, the developmental times decrease with increasing temperatures (Daane et al 2005;Ferreira-Filho et al 2008;Huerta et al 2010). In Italy the phenology, distribution and control capacity of the parasitoid are currently being studied.…”

Alien insects usually adapt their phenology and their needs to the environment into which they are introduced. During 2010, the red gum lerp psyllid, Glycaspis brimblecombei, was accidentally introduced into Italy, becoming an invasive pest of Eucalyptus L'Hér. Eucalypts are very common in Italy as ornamental and forest species. The seasonal adaptation of the psyllid was studied at three field sites. G. brimblecombei showed a seasonal population dynamic, suggesting that many generations occur during the year and the species overwinters in all stages without diapause. The population size in the new area of colonization is affected by low winter temperatures, but also by high temperatures in the absence of rainfall. In Lazio, the specific parasitoid Psyllaephagus bliteus was collected for the first time.

“…Favaro (2006) studied the population dynamics of G. brimblecombei and found no correlation in the numbers of eggs and immatures with rainfall. In contrast , Ferreira Filho et al (2008) and also studied the population dynamics of the psyllids, found that there is direct relationship between decrease in rainfall and increase in populations of G. brimblecombei. Oliveira et al (2012), in studies with artificial rain, found that 2 days of rain are efficient to decrease more than 50% of the population of lerps with almost 100% efficiency after 5 days of rain.…”

“…Since the detection of G. brimblecombei in Brazil studies have been conducted on the biology (Ferreira et al, 2009;Firmino-Winckler et al, 2009;Wilcken et al, 2010), population dynamics (Ferreira Filho et al, 2008), influence of environmental factors (Silva et al, 2010;Oliveira et al, 2012), biological control (Santana et al, 2003;Wilcken et al, 2010) and plant resistance (Pitta et al, 2006;Huerta et al, 2010;Pereira et al, 2013;Camargo et al, 2014). Based on geographical records the potential distribution of G. brimblecombei was predicted with different models using bioclimatic variables (Queiroz et al, 2013).…”

Effect of silicon application to Eucalyptus camaldulensis on the population of Glycaspis brimblecombei (Hemiptera: Aphalaridae)

et al. 2016

The use of silicon in forestry has increased recently as it is directly related to improved resistance to insect pests. The red gum lerp psyllid, Glycaspis brimblecombei, occurs in all eucalypt producing regions in Brazil. Two field experiments were conducted to study the effect of silicon applied to Eucalyptus camaldulensis on the psyllid population. In the first experiment, the applications were made via soil (calcium silicate) and leaves (potassium silicate) in a nine months old E. camaldulensis plantation. In the second experiment, we evaluated silicon on seedlings, incorporating it into the substrate (soil) or applying it on leaves (foliar). Monthly, for 24 months, the number of psyllid eggs and immatures were counted on leaf samples. The plant height was measured at 9, 12, 16 and 24 months (experiment 1) and at 4, 8, 12 and 24 months (experiment 2) after application. The numbers of eggs and immatures were lower in periods of higher precipitation, indicating less psyllid attack during the rainy season. The psyllid population was lower in treatments with application of silicon both foliar and via soil compared to control. No significant differences were found in the height of E. camaldulensis plants. Efeito da aplicação de silício em Eucalyptus camaldulensis em população de Glycaspis brimblecombei (Hemiptera: Aphalaridae) Resumo-O uso do silício na área florestal tem aumentado recentemente, pois o elemento está relacionado a uma melhoria na resistência a insetos pragas. O psilídeo de concha, Glycaspis brimblecombei é encontrado em todas as regiões produtoras de eucalipto no Brasil. O efeito do silício aplicado em Eucalyptus camaldulensis, na população do psilídeo, foi estudado em dois ensaios. No primeiro experimento, as aplicações foram via solo (silicato de cálcio) e foliar (silicato de potássio) em uma plantação de nove meses. No segundo experimento, este mineral foi aplicado em mudas de eucalipto, no substrato ou sobre as folhas. Mensalmente, durante 24 meses, ovos e imaturos de G. brimblecombei foram amostrados nas folhas. A altura das plantas foi medida com 9, 12, 16 e 24 meses (experimento 1) e, aos 4, 8, 12 e 24 meses (experimento 2) após a aplicação dos tratamentos. O número de ovos e de imaturos foram menores nos períodos de maior precipitação, indicando menos ataque dos psilídeos durante a estação chuvosa. A população psilídeo foi menor nos tratamentos com aplicação de silício tanto foliar como via solo. Nenhuma diferença significativa foi encontrada na altura de plantas de E. camaldulensis.
