Аннотация:This is the first report of Thelohania solenopsae infections in monogyne (single-queen) Solenopsis invicta colonies in the field. In a 0.2-ha plot near Baton Rouge, Louisiana, inter-colony prevalence was 63% infection in June, 1999, when the population was 100% monogyne. In February, 2000, 21% of 33 monogyne and 90% of 10 polygyne colonies were infected. By May, 2001, the polygyne colonies had disappeared and only one of 34 monogyne colonies was infected, the final detection of T solenopsae in the plot. Colony size did not differ significantly among the four types (monogyne versus polygyne x infected versus uninfected). (C) 2004 Elsevier Inc. All rights reserved.
