Biology and pathogenicity of the microsporidian Perezia hyperae sp. n., a pathogen of the alfalfa weevil, Hypera postica

Orthosomella lipae sp. n. (Microsporidia) a parasite of the weevil, Liophloeus lentus Germar, 1824 (Coleoptera: Curculionidae)

“…Most descriptions are incomplete and include only morphological features observed under the light microscope (Table 1). Seven of these species were described as belonging to the genus Nosema (Weiser, 1951;Maddox and Luckmann, 1966;Issi and Lipa, 1968;Drea et al, 1969;McLaughlin, 1969;Streett et al, 1975;Youssef, 1974), two were provisionally placed within the genera Canningia (Bruck and Solter, 2005;Bruck et al, 2008) and Unikaryon (Ś wią tek and Górkiewicz, 2006) and four were placed within the collective genus Microsporidium (Hesse, 1905;Malone, 1985;Ghosh, 1990;Lewis et al, 2003). Among microsporidian parasites of weevils only Microsporidium itiiti infecting Argentine stem weevil Listronotus bonariensis, have been studied ultrastucturally (Malone, 1985).…”

“…Dans ehacun de ces cas le tissu museulaire infest6 est progressivement lysd et remplae6 par les spores du parasite. Nous n'avons pas fair d'exp6rimentation pr6cise ~ ee sujet, mais on peut raisonnablement penser que l'activit6 motrice des individus malades est r6duite, comme cela a 6t6 observ6 chez la noetuelle Heliothis armigera Hiibner parasit6e par Nosema manierae Toguebaye & Bouix (Toguebaye & Boulx, 1982) et chez Hypera postica en pr6sence de Nosema hyperae (Youssef, 1974).…”
