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
Invasive species like Harmonia axyridis can pose an ecological threat to native coccinellid species. Other threats to coccinellids include climate change and habitat destruction . These insects have played roles in folklore , religion and poetry, and are particularly popular in nursery rhymes .
Besides anthropocentric values of butterfly gardening, creating habitat reduces the impacts of habitat fragmentation and degradation. Habitat degradation is a multivariate issue; development, increased use of pesticides and herbicides, woody encroachment , and non-native plants are contributing factors to the decline in butterfly and pollinator ...
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]
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]
The Asian ladybeetle species Harmonia axyridis was introduced to the United States in hopes controlling pests like the red pine bast scale. With their introduction, they began to invade other ladybeetle habitats. A particular analysis looked at the relative abundance of the spotless ladybeetle in Florida alongside Harmonia axyridis.
When provided with Harmonia axyridis larvae as part of their diet in the first or third instar stage of development, it has been shown that Olla v-nigrum larvae were incapable of surviving to the adult stage. In the first instar, Olla v-nigrum larvae were shown to have a 100% mortality rate when fed exotic H. axyridis eggs.
