Statilia maculata (Thunberg, 1784) – the first invasive praying mantis (Mantodea,Mantidae) in the fauna of Russia

Summary

Recent years have seen an increasing number of alien praying mantis species being introduced and establishing populations across Europe. Here we add to this count, reporting a stable and spreading population of an Asian species, Statilia maculata (Thunberg, 1784), in Krasnodar Krai of Southern Russia. This is the first introduced praying mantis species in the Russian fauna and the first representative of the genus Statilia Stål, 1877 in Europe. We review what is known about biology of this species and provide diagnostic characters to distinguish nymphs, adults and oothecae from native and introduced European species of praying mantis. Our attempts at captive breeding identify humidity as one of the most important factors limiting possible spread of S. maculata. Invasion to neighbouring territories and other countries with a humid subtropical climate remains a very real possibility with an unknown outcome for local ecosystems.     

Inhibition of new vessel growth in mouse model of laser-induced choroidal neovascularization by adiponectin peptide II

We have investigated the effect of adiponectin (APN) peptide II on new vessel growth in mouse model of choroidal neovascularization (CNV) or wet type age-related macular degeneration (AMD). Mice were injected intraperitoneally with APN peptide II, control peptide, or PBS on day 1-7 or day 5-14. APN, AdipoR1, PCNA, and VEGF localization was investigated using confocal microscopy, immunohistochemistry, and RT-PCR. APN peptide II decreased the relative area of FITC-dextran perfused vessels by 4-fold, PCNA expression by 3-fold, and the number of PCNA stained HUVEC and MAVEC cells by 38 and 46%, respectively. We concluded that APN peptide II inhibits CNV size on days 7 and 14 by inhibiting the proliferation of endothelial cells in vivo and in vitro. APN peptide II may have therapeutic potential to inhibit CNV or wet AMD.
