Novel prey boosts the expansion of host-plant range in a native predatory bug

The predator acceptance of E. camaldulensis leaves as a substrate for oviposition is demonstrated, demonstrating the ability of A. nemoralis to feed and complete a life cycle on exotic novel prey and the acceptance of an exotic host plant.

Organic cropping practice decreases pest abundance and positively influences predator-prey interactions

Predators of the giant pine scale, Marchalina hellenica (Gennadius 1883; Hemiptera: Marchalinidae), out of its natural range in Turkey

Comparing predators reported in previous studies in its native range and those found in the present study showed that 12 of the species that were found are new reports for the species predating upon M. hellenica.

Behavioural mechanisms behind aggregation in a tritrophic perspective

It is argued that females try to avoid the area were the predators are consuming more eggs, possibly leading to better control of those in economic relevant systems.

Reduction of Pear Psylla Damage by the Predatory Bug Anthocoris nemoralis (Heteroptera: Anthocoridae): The Importance of Orchard Colonization Time and Neighboring Vegetation

Preliminary results indeed show that pear psylla densities were lower on pear trees grown near Rhamnus alaternus trees than on distant trees, and it is proposed that planting R. alaternUS trees near pear orchards could enhance the level of biological control of pear Psylla by A. nemoralis.

Oviposition preference of Anthocoris nemoralis and A. nemorum (Heteroptera: Anthocoridae) on pear leaves affected by leaf damage, honeydew and prey

Results showed that prey cues and presence of prey guide predator oviposition is found, even within the single leaf.

Oviposition preference of Anthocoris nemorum and A. nemoralis for apple and pear

The oviposition preferences found correspond to the natural distribution of these predators in apple and pear orchards, and Anthocoris nemorum showed a near‐significant preference for ovipositing on leaves with eggs of Operophtera brumata.

Two Anthocoris bugs as predators of glasshouse aphids – voracity and prey preference

Voracity and prey preference were evaluated for adult females of the predatory bugs Anthocoris nemorum and Anthocoros nemoralis preying upon five species of aphids, of which Myzus persicae Sulzer, Aulacorthum solani, Macrosiphum euphorbiae (Thomas), and Aphis gossypii Glover are common pests in Danish glasshouse crops.


Rates of development and sizes of adults at 23 –2° were determined for six species of Anthocoris reared on a series of host insects. Relative food value of the test prey varied between species of

Can Flowering Plants Enhance Numbers of Beneficial Arthropods in UK Apple and Pear Orchards?

The impact on pest numbers of manipulating the orchard environment by the use of flowering plants was investigated in two ways and the importance of habitat diversity on biocontrol in orchards is discussed.

Functional Response of Four Heteropteran Predators Preying on Greenhouse Whitefly (Homoptera: Aleyrodidae) and Western Flower Thrips (Thysanoptera: Thripidae)

It is concluded that D. tamaninii may have a good action in the control of both greenhouse white fly and western flower thrips, whereas M. caliginosus and both Orius species may be slower in controlling whitefly and be similarly efficient in consuming western flower thriveps.

The role of ecological compensation areas on predator populations: an analysis on biodiversity and phenology of Coccinellidae (Coleoptera) on non-crop plants within hedgerows in Northern Italy

Data demonstrate that some trees and shrubs species can provide shelter for adult ladybirds, mainly in late summer, when many crops in Northern Italy are harvested, and the role of hedgerows and weeds in landscape management is discussed.

Biocontrol of Pests of Apples and Pears in Northern and Central Europe: 2. Parasitoids

It is demonstrated that apple and pear pests are host to a large and varied parasitoid fauna and some effectively regulate pest populations in unsprayed and/or commercial (insecticide sprayed) apple or pear orchards either individually or as part of parasitoids guilds.
