AI Article Synopsis
- Chrysomela populi is identified as a major pest of poplar trees, often infected by protist pathogens, but no specific neogregarine had been documented until now.
- A new neogregarine pathogen was discovered in the Malpighian tubules of C. populi, marked by distinctive reddening symptoms.
- The pathogen was characterized by unique morphological features and named Ophryocystis anatoliensis sp. nov., distinguishing it from known species that infect beetles.
Article Abstract
Chrysomela populi (Coleoptera: Chrysomelidae) is the most abundant and most important pest species that causes damage to poplar trees. Members of the family Chrysomelidae are frequently infected by protist pathogens but no neogregarine has been reported to date at the species level. In the present study we identify a new neogregarine pathogen from the chrysomelid C. populi. The infection was observed in the Malpighian tubules of adult beetles. A reddening of the Malpighian tubules was the most distinctive symptom of the infection. Single fusiform oocysts (9.8×4.7μm) were formed within a gamontocyst. The polar plugs were very thin, varying from 380 to 525nm in thickness. The oocyst wall was smooth and also quite thin (90-120nm). Morphological and ultrastructural characteristics of the pathogen indicate that the described neogregarine in C. populi is clearly different from known Ophryocystis species which infect coleopterans. Therefore, the neogregarine pathogen was determined to be a newly discovered species and named Ophryocystis anatoliensis sp. nov.

Insect-pathogen dynamics can show seasonal and inter-annual variations that covary with fluctuations in insect abundance and climate. Long-term analyses are especially needed to track parasite dynamics in migratory insects, in part because their vast habitat ranges and high mobility might dampen local effects of density and climate on infection prevalence. Monarch butterflies Danaus plexippus are commonly infected with the protozoan Ophryocystis elektroscirrha (OE).

Reports of pollinator declines have prompted efforts to understand contributing factors and protect vulnerable species. While pathogens can be widespread in bee communities, less is known about factors shaping pathogen prevalence among species. Functional traits are often used to predict susceptibility to stressors, including pathogens, in other species-rich communities.

European and Asian honeybees are essential crop pollinators. Microbiome studies can provide complex information on health and fitness of these insects in relation to environmental changes, and plant availability. Amplicon sequencing of variable regions of the 16S rRNA from bacteria and the internally transcribed spacer (ITS) regions from fungi and plants allow identification of the metabiome.
