The life cycles of many organisms are constrained by the seasonality of resources. This is particularly true for leaf-mining herbivorous insects that use deciduous leaves to fuel growth and reproduction even beyond leaf fall. Our results suggest that an intimate association with bacterial endosymbionts might be their way of coping with nutritional constraints to ensure successful development in...

Avoiding detection by parasitoids is nearly impossible for most leafminers in their visually striking mines, and they often suffer from a high mortality rate by a great variety of parasitoid species. The leafminer-parasitoid interaction bears a strong resemblance to the princess-monster game developed in game theory, in which a "monster" (parasitoid) selects an optimal search strategy to captur...

Herbivory alters plant gas exchange but the effects depend on the type of leaf damage. In contrast to ectophagous insects, leaf miners, by living inside the leaf tissues, do not affect the integrity of the leaf surface. Thus, the effect of leaf miners on CO2 uptake and water-use efficiency by leaves remains unclear. We explored the impacts of the leaf-mining moth Phyllonorycter blancardella (Le...

The most important pests of acacia black locust (Robinia pseudoacacia L.) (Fabaceae) are: Appendiseta robiniae Gillette, Phyllonorycter robiniella Clemens, Parectopa Nematus tibialis Newman and Obolodiplosis Haldemann, species from North America, where it also originates the acacia, which is host plant. In Europe these were introduced accidentally, being considered invasive species. Europe, O. ...

The aim of the research was to present current data on distribution and development some alien phytophagous insects in territory Ukraine.We considered 19 species insects, including 2 Coleoptera, 7 Hemiptera (including 4 bug species), Lepidoptera, Hymenoptera, 1 Diptera. Hyphantria cunea penetrated Ukraine about 70 years ago sometimes outbreaks orchards or shelterbelts. Cameraria ohridella Cydal...
