“…These are bacterial endosymbionts in the genera Rickettsia, Spiroplasma, and Wolbachia, which are common among ladybirds but generally only infect a small proportion of populations (WEINERT et al 2007). GORYACHEVA et al (2017) found no infection of invasive populations (in Czech Republic, Germany, Italy, Russia, and the USA) with Spiroplasma, wheras all native populations were found with the bacterium. Rickettsia and Wolbachia, on the other hand, were found in both invasive (1.12% of females infected for both bacteria, n = 179) and native populations (0.51% and 1.02% of females infected, respectively; n = 196).…”

Continued collecting efforts in the Middle East region will be accompanied by efforts to screen female ladybirds for presence of bacteria using amplifi cation of the fbpA (for Wolbachia) and gltA (for Rickettsia and Spiroplasma) genes with specifi c primers (BALDO et al 2006, GORYACHEVA et al 2017.…”

Abstract The harlequin ladybird, Harmonia axyridis (Pallas, 1773), is native to Asia but has been introduced to many countries, both intentionally and unintentionally. In the Middle East region, H. axyridis was so far only known from Iran and Turkey. This study reports H. axyridis for the first time from a country with a hot desert climate, Saudi Arabia. The single specimen that was found is most likely the result of unintentional release. Successful spreading of H. axyridis in Saudi Arabia will be limited because of high temperatures during summer and scarcity of prey (aphids). New records from Iran and Turkey suggest fast spreading of H. axyridis in these parts of the Middle East. In addition, we also present new records from Iran and Turkey for H. quadripunctata (Pontoppidan, 1763), the other species in the genus that occurs in the Middle East region. A key and illustrations are provided for both species.

“…axyridis native range. The two most common strains–HARFUKU1 and HARFUKU2 –as well as two minor strains–Sib1 and Sib19 –have been previously noted in Japanese and Novosibirsk populations, respectively [ 42 , 37 ]; the rest of the strains described here are recorded for the first time. Our study is the first to note the diversity of Spiroplasma from a single host.…”

“…To study Spiroplasma polymorphism from H . axyridis , we used DNA samples of 16 Spiroplasma -infected beetles from Eastern and Western populations, of which the infectious status was determined previously by us [ 42 ]. Twelve samples originate from females from the Eastern population, including six samples from Vladivostok (V) and Troitsa Bay (Tr) and two samples from Kyoto (K), as well as four samples from females of the Western population, including two samples from Novosibirsk (N) and two samples from Gorno-Altaisk (G).…”

The heritable endosymbiotic bacterium Spiroplasma is found in the harlequin ladybird Harmonia axyridis. The proportion of beetles infected with Spiroplasma in different native H. axyridis populations varies from 2% to 49%. We investigated the polymorphism of Spiroplasma strains in samples from individual beetles from Kyoto, Vladivostok, Troitsa Bay, Novosibirsk, and Gorno-Altaisk. To identify Spiroplasma strains, we analyzed nucleotide polymorphisms of the 16S rRNA gene and the ribosomal internal transcribed spacer (ITS1). The majority of infected beetles were infected with two or more Spiroplasma strains. We measured Spiroplasma density in beetles with different infection status using quantitative PCR. The abundance of Spiroplasma in samples with a single infection is an order of magnitude lower than in samples with multiple infections. Density dependent biological effects of Spiroplasma are discussed.
