摘要: Twelve species of Gryllinae were studied to determine the number, morphology and behavior their chromosomes. The male diploid numbers ranged from 19 31. Gryllus campestris a population "G. bimaculatus" Singapore showed anomalies in chromosome structure, including breaks, stickiness, C-mitosis, polyploidy, lagging, unequal segregation non-disjunction former many aberrations loss fertility latter. One or two B-chromosomes occurred some individuals G. veletis, number this thus varying 2n ♀ = 29 In Gryllinae, karyotypic differences are shown be more useful than at level; taxonomically generic level, when combined with karyotypes.
