Among predators, Harmonia axyridis
(Pallas) (Coleoptera: Coccinellidae) and Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) are used in augmentative and conservation biological control programs in several crop cultures in various regions of the world (Albuquerque et al.
and Harmonia axyridis
[Pallas]) are known to prey upon Uroleucon aphids in natural and semi-natural settings, raising concerns about their nontarget effects on native aphids.
Right, lady beetles, Harmonia axyridis
Pallas, feed on psyllid nymphs.
At certain times of the year, the multicolored Asian lady beetle, Harmonia axyridis
, comes inside--sometimes in large swarms--to escape the cold.
The harlequin ladybird, Harmonia axyridis
, is just one example of the negative impact alien species can have when they are introduced outside of their natural environment.
The humble ladybird, scourge of greenfly and other garden pests is in danger of being wiped out at the hands of its foreign cousin, Harmonia Axyridis
Multicolored Asian lady beetles (MALB), Harmonia axyridis
(Pallas) were introduced as biocontrol agents to control the pecan aphid, pear psylla and other soft-bodied insects.
Imported insects include the dacnusa wasp, harmonia axyridis
and pirate bugs.
