Harmonia axyridis is native to eastern Asia from central Siberia, Kazakhstan, and Uzbekistan in the west, through Russia south to the Himalayas and east to the Pacific coast and Japan, including Korea, Mongolia, China, and Taiwan. As a voracious predator, it was identified as a biocontrol agent for aphids and scale insects.
The widespread and invasive Harmonia axyridis. Coccinellidae are found on every continent except Antarctica. [74] Asian and African species are less studied than others. [75] Coccinellids can be found in a variety of habitats, both on the ground and in the trees. They may specialise using certain plants.
The Cycloneda sanguinea is a relatively dominant and widespread predator. However, in some areas, its population has been on the decline due to the introduction of another ladybeetle species. The Asian ladybeetle species Harmonia axyridis was introduced to the United States in hopes controlling pests like the red pine bast scale. With their ...
Parasitylenchus bifurcatus parasitizes Harmonia axyridis, a beetle introduced to Europe from central and South Asia. [7] H. axyridis affects agricultural crops such as apples, pears, and grapes resulting in reduced quality of products made from these crops. [7] [8] Both male and female H. axyridis can be infected by P. bifurcatus. [7]
It is an ectoparasite of an invasive species to Europe and the Americas, [4] the harlequin ladybird (Harmonia axyridis). [5] Laboratory bioassays pointed out that Hesperomyces-infected ladybirds suffered increased mortality rates. [6]
Harmonia axyridis (Pallas, 1771) – Asian lady beetle, originally from Nepal, China, Taiwan, Japan, introduced to Western Europe and America; Harmonia antipodum (Mulsant, 1848) – antipodean ladybird, endemic to New Zealand; Harmonia basinotata Bielawski, 1964 – New Guinea; Harmonia bicolor (Blackburn, 1892) – Australia
Like many other insects, one of the main predators to the orange-spotted ladybird are birds. The shining cuckoo [17] and starlings [18] are examples of birds that are often predators of the orange-spotted ladybird. Another predator is the harlequin ladybird, Harmonia axyridis, which has recently arrived in New Zealand. [19]
3rd instar larva of Harmonia axyridis eating an egg of another ladybird species (probably Adalia) Invasive species frequently prey on eggs and young of native species. The harlequin ladybird Harmonia axyridis eats eggs of species including other ladybirds, such as the two-spot ladybird Adalia bipunctata. Females of the prey species laid eggs ...
