Nosema chrysorrhoeae n. sp. (Microsporidia), isolated from browntail moth (Euproctis chrysorrhoea L.) (Lepidoptera, Lymantriidae) in Bulgaria: characterization and phylogenetic relationships.

چکیده
A new microsporidian parasite Nosema chrysorrhoeae n. sp., isolated in Bulgaria from the browntail moth (Euproctis chrysorrhoea L.), is described. Its life cycle includes two sequential developmental cycles that are similar to the general developmental cycles of the Nosema-like microsporidia and are indistinguishable from those of two Nosema spp. from Lymantria dispar. The primary cycle takes place in the midgut tissues and produces binucleate primary spores. The secondary developmental cycle takes place exclusively in the silk glands and produces binucleate environmental spores. N. chrysorrhoeae is specific to the browntail moth. Phylogenetic analysis based on the ssu rRNA gene sequence places N. chrysorrhoeae in the Nosema/Vairimorpha clade, with the microsporidia from lymantriid and hymenopteran hosts. Partial sequences of the lsu rRNA gene and ITS of related species Nosema kovacevici (Purrini K., Weiser J., 1975. Natürliche Feinde des Goldafters, Euproctis chrysorrhoea L., im Gebiet von Kosovo, FSR Jugoslawien. Anzeiger fuer Schädlingskunde, Pflanzen-Umweltschutz, 48, 11-12), Nosema serbica Weiser, 1963 and Nosema sp. from Lymantria monacha was obtained and compared with N. chrysorrhoeae. The molecular data indicate the necessity of future taxonomic reevaluation of the genera Nosema and Vairimorpha.

Factors influencing larval survival of the invasive browntail moth (Lepidoptera: Lymantriidae) in relict North American populations.
Scant attention has been paid to invasive species whose range and abundance has decreased after an initial range expansion. One such species is the browntail moth Euproctis chrysorrhoea L, which was discovered in the eastern United States in 1897. Its range expanded until 1914; after 1915, however, its range contracted and now it persists in only two isolated coastal locations. Although a biolo...

The lepidopteran family Lymantriidae contains about 200 genera and about 2,500 described species, mostly from the Old World Tropics (DeWorms, 1983). Of the 46 recognized species and subspecies of Lymantriidae in North America, 30% are considered pests (Ferguson, 1978). The pest species include three introduced species which have become established in North America, the gypsy moth, Lymantria dis...

Simultaneous and sequential per os inoculations of gypsy moth larvae with the Lymantria dispar nuclear polyhedrosis virus (LdNPV) and a Nosema sp. from Portugal demonstrated that the interaction of two pathogens during coinfection was variable, ranging from synergistic to antagonistic. Susceptibility of gypsy moth larvae to viral infection was unaffected by simultaneous and subsequent microspor...

Recent attention has focused on the harmful effects of introduced biological control agents on nontarget species. The parasitoid Compsilura concinnata is a notable example of such biological control gone wrong. Introduced in 1906 primarily for control of gypsy moth, Lymantria dispar, this tachinid fly now attacks more than 180 species of native Lepidoptera in North America. While it did not pre...
