The role of certain factors viz., age of the insects, food source, CO_2-anaesthesia, mating status and age of plants in influencing the substrate-borne acoustic communication associated with the sexual behaviour of the leafhopper. Amrasca devastans (DISTANT) (Homoptera : Cicadellidae) was studied under the laboratory conditions. The sound emission and mating responses increased from nil in 1-day-old insects to maximum in 5-day-old ones and declined thereafter. The leafhoppers reared on the non-host cucurbit, Lagenaria siceraria, showed a high degree of sound emission and mating but those reared on sucrose solution did not exhibit these responses. Such differences were related with equal maturation of oocytes on the host and non-host but not on the sucrose solution.The CO_2 anaesthesia was found to inhibit the sound emission and mating in this leafhopper and its effect on the females was greater than the males. Mating inhibited the subsequent sound emission and mating of the females but had no effect on the males. The sexes of this leafhopper could communicate and mate when present anywhere on the young (1-2 months) plants but could not do so freely on older (5-6 months) plants.
