However, little is known about how the volatiles from the aromatic plants regulate the behavior of the spirea aphid and its lady beetle
natural enemy; this is information that would be useful for biocontrol in apple production.
convergens, from which they recovered 46 pollen grains from 43 adults, being six pollen grains of Apiaceae, but without identifying the botanical species; however, most of the pollen grains found in the digestive tract of this lady beetle
belonged to Asteraceae (16 grains of Aspilia Thou.
One of the shortcomings of lady beetles
for biological control is they can fly
These data show certain aspects of the patterns of pigment distribution on the pronota of multicolored Asian lady beetles
are correlated with the patterns on their elytra.

(Coleoptera: Coccinellidae) Activity and Wine Grape Phenology: Implications for Pest Management.
The objective of this study was to estimate risk to Uroleucon aphids from non-native lady beetles
by determining incidence of lady beetles
on Uroleucon-occupied plants in eastern South Dakota, and by evaluating the acute impact on Uroleucon prey by selected lady beetle
species in no-choice laboratory tests.
The lady beetle
eats the scale insects tended by the ants.
The one that was seen in large numbers last fall was the nonnative multicoloured Asian lady beetle

The beetle is also know as the Harlequin Ladybird or Multi-Coloured Asian Lady Beetle
Sampling was initiated on 15 September 2002 at five of the original ten release sites, and was subsequently expanded to include the original ten sites where mass releases of the lady beetle
When the weather turns colder, lady beetle
adults begin to seek wintering sites, often in a house.
Asian lady beetle
(Harmonia axyridis (Pallas)) populations in soybean fields were low during 2004 probably due, in large part, to the decreased abundance of soybean aphids.
For example, the two-spotted lady beetle
may be common in Calgary, but in the eastern prairies it is rare and the thirteen-spotted lady beetle
is as common as the seven-spotted.
In 2001, the soybean aphid was quite abundant and the lady beetle
