Chromosomal aberrations in the testicular and ovarian cells of rhinoceros beetle infected
with baculovirus in vivo were studied. Chromosomal/chromatid breakage (female 32.2%,
male 28.20/.) and centromeric dissociation (female 29.6%, male 24.00/.) were more frequent
among the aberrations followed by aneuploidy (female 14.8%, male 6.3%), acentric (female
11.60/., male 4.5%) and centric (female 2.8%, male 1.3%) fragments. Metacentrics were 1.6%
and 1.2%, respectively, in the female and male cells. Females were more susceptible to the
virus infection in terms of chromosomal aberrations compared to male beetles, the total
frequency of aberrant cells being 65.5% in males and 92.6% in females. The mean number
of abnormalities per aberrant cell was 1.01 in both male and female.
