Manipulation of plant odour preference by learning in the aphid parasitoid Aphelinus abdominalis (Hymenoptera: Aphelinidae)

Role of the aphid species and their feeding locations in parasitization behavior of Aphelinus abdominalis, a parasitoid of the lettuce aphid Nasonovia ribisnigri

Aphid species feeding on lettuce occupy distinct feeding sites: the lettuce aphid Nasonovia ribisnigri prefers to feed on heart leaves, whereas the potato aphid Macrosiphum euphorbiae feeds only on outer leaves. The aphid parasitoid Aphelinus abdominalis, known to be able to regulate M. euphorbiae on many crops, has recently been indicated as a promising biocontrol candidate also for use agains...

defense reactions of the grape aphid, aphis illinoisensis (hemiptera: aphididae) to parasitoid species lysiphlebus testaceipes (hymenoptera: braconidae) and aphelinus albipodus (hymenoptera: aphelinidae)

developmental periodsof thegrapevine aphid, aphis illinoisensis shimer (hemiptera: aphididae) on the grape, vitis vinifera l., and its two parasitoid species, lysiphlebus testaceipes (cresson) (exotic) (hymenoptera: braconidae: aphidiinae) and aphelinus albipodus hayat and fatima (indigenous) (hymenoptera: aphelinidae) were studied at two constant temperatures (20 and 25 ± 2 oc), 70 ± 5 % r.h. ...

First report of Aphelinus semiflavus Howard, 1908 (Hymenoptera: Aphelinidae) in Brazil.

Temperature adaptability of two clades of Aphelinus mali (Hymenoptera: Aphelinidae) in China

Aphelinus mali (Haldeman) (Hymenoptera: Aphelinidae) is an effective natural enemy used in China to control the woolly apple aphid (Eriosoma lanigerum [Hausmann]) (WAA). Population of A. mali in China falls into two distinct genetic clades (Shandong clades and Liaoning clades). In the present results, the developmental threshold temperature of the Shandong clade (9.82 ± 1.44 °C) was lower than ...
