Sažetak
Asian lady beetle Harmonia axyridis Pallas was introduced in USA and
Canada at the beginning of the last century. In 1995, it was introduced in Europe as a biological tool to control aphids. Nowadays, insect is distributed in the most European countries. In 2010 it was recorded on currant, gooseberry, nettles and wild cherry in Croatia, Ratkovica (Pleternica). In fall 2010, it was recorded in Kutjevo area, in vineyards, as well as in households in area of Semeljci in populations with great abundances. Harmonia axyridis is characterized by great polymorphism. They predate on aphids, but also can feed on larvae of other ladybirds. It can be found on mature fruits and grapes. Infected clusters of grapes should be segregated while processing, otherwise wine decreases its quality because of the presence of alkaloids. While overwintering, they tend to group, and this is one of the leading characteristics indicating this species
since other lady beetle do not group. Often, they are household nuisance, and can cause allergies. It is important to stop using this insect species as biological control option. Integrated pest management is advised in control of multicoloured Asian lady beetle, such as mechanical measures, natural enemies and predators. Chemical measures should be avoided because of the detrimental effect on other useful lady beetle.
