Occurrence of arthropods on abandoned apple trees was studied in 2010 and 2011. The research was carried out in South Moravia (Czech Republic). Two sites were selected within this area -apple trees (Malus domestica) in an alley along a road and an abandoned apple orchard. At each location, arthropods were collected from 5 separate trees. Deltamethrin was applied into the treetops using a fogger. The killed arthropods were collected 15 minutes a er the application. From among the collected data, 48 families were determined in accordance with a generalized linear model with a logarithmic-link function and Poisson distribution. As a result it was found that 33 families have signifi cantly higher abundance in the abandoned orchard and 9 families in the alley. According to the Shannon-Wiener index, diversity of families was higher in the alley in both years

Diversity and Flight Activity of Parasitoids Hymenoptera in Apple Orchard in Vacaria, RSAbstract. The objective of this work was to evaluate the diversity of parasitoids Hymenoptera and the period of flight activity in apple trees. Insects were sampled with Malaise traps weekly for a period of 24 hours, being removed from the trap in the following times 1, 7, 13 and 19 hours. A total of 1,249 individual parasitoids from 25 families were collected. The most abundant families was Ichneumonidae (318), Bethylidae (199), Figitidae (Eucoilinae) (183), Braconidae (90) and Scelionidae (86). With the exception of Ichneumonidae (Ophioninae), parasitoids were most commonly collected during daylight.

“…Extrafloral nectar glands increased the abundance and activity of arthropod predators and parasitoids in peach (Prunus persica Batsch) orchards compared with peach orchards of the same cultivar lacking nectar glands (Mathews, 2004). Interplanting of extrafloral nectar-bearing stone fruit trees into an apple orchard has also increased the diversity of predacious arthropods on apple (Brown and Schmitt, 2001). Peach extrafloral nectar has been shown to increase longevity and fecundity of predators and parasitoids of orchard pests (Hagley and Barber, 1992;Limburg and Rosenheim, 2001;Shearer and Atanassov, 2004).…”

Effect of floral and extrafloral resources on predation of Aphis spiraecola by Harmonia axyridis on Apple

Flowering companion plants and plants producing extrafloral nectar are being proposed to enhance biological control in apple (Malus domestica Borkh.) orchards. This experiment evaluated the impact of floral and extrafloral resources on predation of spirea aphid (Aphis spiraecola Patch) on apple by adult Harmonia axyridis (Pallas) under greenhouse conditions. Predation of spirea aphids was not affected by the presence of flowering buckwheat (Fagopyrum esculentum) as compared with either buckwheat with flowers removed or an uninfested apple shoot. However, there was a significant reduction in predation of spirea aphids on an apple shoot in the presence of a peach shoot with extrafloral nectar glands compared with either a peach shoot of the same cultivar without nectar glands or an uninfested apple shoot. These findings demonstrate that alternative food resources potentially could interfere with rates of biological control and, therefore, need to be carefully evaluated before incorporating in an orchard design. More studies are needed to adequately gauge the net effects of adding floral or extrafloral resources in orchards for conservation biological control.
