Abstract Nymphs of the Indian stick insectCarausius morosus, Brunner were maintained at ambient or 4.2×104 negative ions per c.c. Regenerative processes were initiated in each nymph by stimulation of the leg autotomy reflex. Aspects of growth, the moulting cycles and leg renewal were studied. Few significant weight differences were found between the insects growing in the control and ionized environments. However, the growth curve of the ion treated insects was irregular, unlike that of the control group which increased smoothly. Slight delays in the intermoult period and in the rate of leg regeneration were also noted in those insects exposed to negative ions. Previous workers have shown significant increases in the growth of some insects exposed to negative ions. These new results show no significant effects but suggest growth may be inhibited.
