“…In general, females of most insect species are much heavier than their male counterparts [ 43 , 44 ]. This observation was also determined to be true for female beetles in earlier studies of Gonioctena quinquepunctata [ 45 ] and Altica brevicollis coryletorum [ 14 ]. Changes in the body mass of current-year beetles of both sexes occurred as a direct result of the amount of feeding.…”

Body mass and sex ratio (F/M) of folivorous insects are easily measured parameters that are commonly used to assess the effect of food quality, living conditions, and preferences on the selection of favourable sites for offspring. A study was conducted on the polyphagous beetle, Gonioctena quinquepunctata (a pest of the native Prunus padus and alien P. serotina) and on the monophagous beetle, Altica brevicollis coryletorum (a pest of Corylus avellana). Both species have a similar life cycle with emergence of current-year adults in summer, and reproduction of 1-year-old insects in spring. A. brevicollis coryletorum feeds primarily on sunlit shrubs, while G. quinquepunctata prefers shaded leaves. The present study assessed the effect of time of occurrence (insect age) on body mass in both sexes and on the sex ratio F/M, taking into account the influence of light conditions associated with their favoured food source (sunlit vs. shaded leaves). We hypothesized that a change in body mass in current-year insects would be determined by the amount of consumed food, while the sex ratio would be stable, when in 1-year-old insects females would die shortly after oviposition, while males would be active for a prolonged time. Results confirmed the hypothesis that changes in mass of current-year beetles was determined by the amount of food intake. We also found that in spring, unfertilized females coexist with fertilized ones and that the latter females live for some time after oviposition; resulting in fluctuations of the mean mass for females. In both species, 1-year-old beetles were heavier than current-year. The preference of A. brevicollis coryletorum for sunlit leaves results in a higher body weight than in G. quinquepunctata in both seasons. The data are consistent and indicate seasonal fluctuations in body mass and changes in the sex ratio in 1-year-old beetles, due to the entrance into their reproductive period.

“…Moreover, the same folivorous species occur for both species, but P. padus experiences a much greater loss of leaf mass as a host than does P. serotina (Karolewski et al, 2013). A variety of mono-and polyphagous insect pests, especially the leaf beetle Gonioctena quinquepunctata F. (Mąderek et al, 2015), aphid Rhopalosiphum padi L. (Halarewicz & Gabryś, 2012) and Yponomeuta evonymellus L. , have more food sources due to the presence of alien species, so their increased populations may simultaneously pose a greater risk to P. padus (as it is their primary host). In addition, the invasive P. serotina is extremely resistant (P. padus is as well, but to a lesser extent) to various leaf mass reducing factors, such as insects (Halarewicz & Jackowski, 2011), artificial defoliation (Karolewski et al, 2010), mechanical damage of branches or even complete removal of the aboveground part of shrubs (Annighöfer et al, 2012).…”

Particulate matter accumulation -further differences between native Prunus padus and non-native P. serotina Received: 14 April 2017; Accepted: 23 June 2017 Abstract: Particulate matter (PM) is one of the most harmful inhaled pollutants. Where pollutants have been emitted into the atmosphere, the most effective method for cleaning the air is through phytoremediation, whereby plants act as biological filters. PM has a negative impact on plants, but knowledge of PM effects on the photosynthetic apparatus is limited. In European forests, species of the genus Prunus L. play a key role in the composition of the forest understory and urban as well as industrial plantings. Shrubs of the native P. padus L. and closely-related invasive alien P. serotina Ehrh. are particularly widespread. Thus, both are good model species in which to study the impact of PM pollution. The aim of this study was to assess the accumulation of PM in the context of leaf morphology and amount of epicuticular waxes on foliage, and the efficiency of the photosynthetic apparatus of P. padus and P. serotina. The study was conducted under controlled conditions using two variants of dust, cement and roadside PM. In addition, we analyzed the absorption of dust by leaves dividing it into three fractions by size (10−100 µm, 2.5−10 µm and 0.2−2.5 µm). Results showed that both P. padus and P. serotina accumulate PM mostly on the surface of their leaves ( S PM), rather than in the wax layer ( W PM). P. padus accumulated higher amounts of PM than did P. serotina. The higher presence of PM on leaves of P. padus resulted in a reduction of the efficiency of the photosynthetic apparatus, manifested by lower rates of photosynthesis and chlorophyll a fluorescence, coinciding with an increased stomatal resistance. A strong negative correlation was found between the amount of PM accumulation and the efficiency of the photosynthetic apparatus in P. padus, but not in P. serotina. We have concluded that alien P. serotina is more tolerant to the conditions of stress caused by PM pollution than is the native P. padus, which may partly explain its success in the invasion in Europe.

“…For example, invasive Prunus serotina Ehrh. demonstrates a strong and close phylogenetic relationship with native P. padus L. (Bortiri et al 2001), and differences in food quality are small, so native specialists (Karolewski et al 2014) and generalists (Nowakowska and Halarewicz 2006;Mąderek et al 2015) have adapted to carrying out the entire life cycle with this new plant. Between Salix viminalis and Spiraea tomentosa, there is no close phylogenetic affinity, and our measurements show that the leaves of these two species differ significantly in relation to both chemical and morphological features.…”

“…As insects are strongly dependent on their preferred food (Ehrlich and Raven 1964;Coley et al 2006), feeding on the optimal host plant allows them to obtain a larger body size (Haukioja and Neuvonen 1985;Ohmart et al 1985;Awmack and Leather 2002). Choosing a suboptimal host plant may result in a decrease in adult insect mass (Mąderek et al 2015) and may extend larval development time, thereby increasing larval mortality due to prolonged exposure to predators and parasitoids (Häggström and Larsson 1995;Williams 1999;Chen and Chen 2016). Decrease in the number of natural enemies is usually observed in the case of plant species relocated beyond their natural range (Keane and Crawley 2002), but native insect species are able to utilise neophyte plant species (e.g.…”

The introduction of alien species can have a significant impact on the food preferences of native phytophagous insects. The moth Earias clorana L. has previously been considered to be monophagous, ingesting only plants in the genus Salix. In recent years, we have observed larval E. clorana feeding on Spiraea tomentosa L., an invasive shrub species in Central Europe that is native to North America. We hypothesised that this insect can feed on Spiraea tomentosa leaves with no negative effects on its growth and development, and that the leaves of Spiraea tomentosa as a source of food for E. clorana are equally as good as leaves of Salix viminalis L. Our results showed that despite significant differences in the chemical composition of the studied species' leaves, including a much higher concentration of defence compounds (total soluble phenols and condensed tannins) in Spiraea tomentosa leaves than in those of Salix viminalis, feeding on a new host plant did not significantly affect the survival of larvae. The change in host plant had an unfavourable effect, however, on several parameters of growth and development for the larvae (masses of larvae and pupae, relative growth rates, and efficiency of conversion of ingested food). We conclude that, in comparison to Salix viminalis, Spiraea tomentosa is not a particularly favourable food for larval development. Perhaps, even without direct improvements in adult foraging efficiency, however, the costs of switching hosts may be minimised in larvae that develop on very abundant, invasive species, such as Spiraea tomentosa in Central Europe.
