Field observations on Harmonia axyridis Pallas (Coleoptera: Coccinellidae) in Oregon. New records of coccinellid species for the Province of Manitoba. Insectarium, 13:294-298, Tedders WL, Schaefer PW, 1994. H. axyridis is highly variable and over 100 colour forms have been identified worldwide. In regions with an extended warm season they may have up to five generations (Wang, 1986). Not only do H. axyridis cause blemishing to the fruit, but they are hard to remove from clusters of grapes and so get crushed during harvest and crop processing. (NB) 2015-06-16 charlotte schweitz Beneficial organisms associated with ornamental pests. South African Journal of Science. It is apparent that H. axyridis is one of the top predators within the guilds of aphidophages and coccidophages and it will survive on a varied diet with the potential to engage in intra-guild predation, including other species of ladybird (Yasuda and Ohnuma, 1999; Ware and Majerus, 2008; Ware et al., 2008). Neonate female siblings consume the inviable male eggs and, thus, are less likely to starve than first-instar larvae produced by females who do not carry the male-killer (Majerus et al., 1998). H. axyridis has been shown to reproduce successfully in a wide range of climates, whereas many species of coccinellid are more habitat and niche-specific. Observations of the biological characteristics of Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae). Su cabeza puede ser de color negr… Although in favourable conditions it can be multivoltine and up to four or five generations per year have been observed (Wang, 1986; Katsoyannos et al., 1997). Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) found in Newfoundland. The ground colour may be orange, red or black. The occurrence of Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) in Canada. Majerus (1994) reports that in predatory interactions between coccinellid larvae it is generally the larger that eats the smaller, as long as both are mobile, therefore the large size of H. axyridis compared to many coccinellids may also contribute to its competitive advantage. Chemical control of H. axyridis in field situations such as orchards and vineyards is feasible, but less applicable because of the impact of insecticides on other aphidophages and beneficial insects.

H. axyridis pupae have been found on imported cut flowers and fruit (Majerus et al., 2005b). The presence of H. axyridis larvae within an aphid colony may reduce the rate that parasitoids oviposit (Takizawa et al., 2000) and so reduce their numbers.

H. axyridis preys on a wide variety of tree-dwelling homopteran insects, such as aphids, psyllids, coccids, adelgids and other insects (Tedders and Schaefer, 1994; Hodek, 1996; Koch, 2003).

Michaud (2002c) demonstrated that H. axyridis was more voracious, fertile and fecund than C. sanguinea and consequently directly out-competed C. sanguinea. 29 (1), 25-26. http://www.habitas.org.uk/inj/, Nedvěd O, Háva J, 2016.
