Abstract
SUMMARYChiasma frequencies have been determined for three species of Oxya which occur sympatrically in a number of localities in Selangor State, Peninsular Malaysia. O. diminuta differs significantly from O. fuscovittata and O. japonica japonica in mean chiasma frequency, but not in log. cell variance. The latter two species show significant variation between populations for both metrics, whereas variation is barely significant in O. diminuta. In all species between-individual variance is low. The effect of high ambient temperature during periods of low rainfall is evident in greater variation in chiasma frequency between cells within individuals of these hygrophilous species. They differ in their response to dryness according to their microhabitat preferences. Climatic factors and human interference cause fluctuation in size of natural populations, and the potential influence of inbreeding on chiasma frequency in this group of grasshoppers was indicated by study of a cultured population of O. japonica ja...
