AB  - To gain some insight into the structure of the hoverfly community in fields of oilseed rape (Brassica napus L.), we conducted field experiments over three years (2011-2013) at two localities in the province of Vojvodina, northern Serbia. We recorded a total of 20 hoverfly species. Three species-Episyrphus balteatus (De Geer, 1776), Eristalis tenax (Linnaeus, 1758) and Eupeodes corollae (Fabricius, 1794)-were the most abundant in both localities and in each year. In order to determine the effect of climatic and non-climatic parameters on abundance and diversity of hoverflies, two separate PCA analyses were carried out. Multiple linear regressions were used to examine the relationships between abundance and extracted PC axes, while ordinal multinomial regressions were conducted to determine the relationships between species diversity and extracted PC axes. We did not detect statistically significant correlations between climatic and non-climatic parameters and overall hoverfly abundance. PC axes exhibited slight correlation with species diversity. The first PC axis clearly showed that overall species diversity increases with increasing temperature, relative humidity and diversity of crops surrounding the surveyed plots, whereas PC2 related species composition with monthly average rainfall and the season and year of observation. Synecological analysis of our data indicated that only a few species are major contributors to hoverfly communities on the oilseed rape crops we investigated. However, the importance of less abundant hoverfly species should not be underestimated, as sometimes these species play an important role in pollination in a specific part of the day or season, and this should be considered when creating agricultural policies and regulations, especially when it is known that abundances of hoverflies and pollinators in general are positively correlated with floral abundance and abundance flowering plant species.

AB  - Sunflower seeds are regularly infested by Plodia interpunctella during storage. Although this pest prefers damaged seeds, in practice it can infest undamaged seeds as well. This research assessed the influence of the sunflower seed type (oil, protein for human consumption and bird-feed) and the initial seed damage during post-harvest processing (dehulled kernels, 10, 20, 30% of damaged seeds and undamaged seeds) on development of P. interpunctella (larval mortality, larval development, mean developmental duration, adult emergence and fecundity). Biochemical analysis of seeds, kernels and hulls detected the highest content of phenols in the seed and hull and tocopherols in the kernel of the oil type hybrid. The anti oxidative activity was the highest in the seed, kernel and hull of the protein type for bird feed. The shortest development (39.5 days) and the highest fecundity (91.3) were on the oil type seeds, while the longest development (42.1 days) and the lowest fecundity (68.1) were on the seeds of the protein type for bird feed. The highest mortality of larvae was on the undamaged seeds of the protein type for bird feed and human consumption (21.3% and 14.0%, respectively). The type of sunflower and the level of initial damage affected larval mortality, developmental duration and fecundity. The mean developmental duration and the number of emerged adults were dependent only on the initial seed damage. Principal component analysis detected strong positive correlation between mortality and development with the tocopherol content on the undamaged seeds while fecundity was associated with the state of kernel and the amount of tannins, proteins and oil content in the seed. The undamaged seeds of the protein type for the bird feed were the least suitable for the development of this pest, while the oil type kernels were the most suitable.
