ABSTRACT. In the present study, Japanese populations of gypsy moth Lymantria dispar japonica (Motschulsky, 1860) and L. postalba (Inoue, 1956,) were screened for the presence of two maternally-inherited bacterial symbionts (Wolbachia and Spiroplasma) and Microsporidia. Both Microsporidia and Wolbachia were absent in all examined individuals (N = 99) while presence of Spiroplasma was registered at 3.9 % prevalence rate (N = 51) in L. dispar japonica population. We discuss the possible role of these microorganisms in gypsy moth population dynamics.
KEY WORDS: bacterial symbionts, pathogens, insects-defoliators, prevalence, population variation.
