What is Two Anthocoris bugs as predators of glasshouse aphids – voracity and prey preference about?

## Abstract Voracity and prey preference were evaluated for adult females of the predatory bugs __Anthocoris nemorum__ (L.) and __Anthocoris nemoralis__ (Fabricius) (Heteroptera: Anthocoridae) preying upon five species of aphids (Homoptera: Aphididae), of which __Myzus persicae__ Sulzer, __Aulacorthum solani__ (Kaltenbach), __Macrosiphum euphorbiae__ (Thomas), and __Aphis gossypii__ Glover are common pests in Danish glasshouse crops. __Aphis fabae__ Scopoli was included to determine the influence of food quality on the preference of the predators, since __A. fabae__ has proved to be of poor nutritional value to __Anthocoris__ spp. The experiments were carried out over 24 h in climate cabinets at 20 °C, 60–70% r.h., L18:D6. The aphids were offered in equal amounts in combinations of two species in instars of comparable size. __Myzus persicae__ served as a reference species in all combinations. Both predators accepted all five species of aphids as prey. The numbers of aphids killed per 24 h period varied between 3.7 and 18.0 for __A. nemorum__ and between 3.6 and 12.7 for __A. nemoralis__. Field collected __A. nemorum__ females, presumably in a state of reproductive diapause, killed
