“…The largest response reported is by Mackay et ale (1974) who obtained a reduction in larval population in existing pasture from 8137 to 3233/m 2 and an increase in pasture growth during winter from 1275 to 2728 kg DM/ha, Le., a 114°;& increase in pasture growth resulting from a 4904/m 2 decline in larval population. Responses of similar magnitude and within the ranges mentioned herein have been reported elsewhere (Cumberland et ale 1973;Cumberland & Honore 1973;Dixon & Davison 1976, Dixon 1974Wilcocks 1974 (data from a trial in pots)) .…”

Use of insecticides during autumn to control soldier fly larvae and increase pasture production

A range of insecticides, their formulations, rates of application, and method of distribution were tested. Carbofuran and isophenphos proved most effective, but control was poor (46-66% mortality in autumn trials). There was no difference between seed treatment and granular formulations although spraying high rates (6.0 kg a.i.z'ha) on to existing pasture proved effective. Results indicate that during winter-spring pasture production was related to larval population and that a population reduction of 1000 larvae/rn-is likely to produce an additional 156 kg DM/ha, i.e., in these trials a 3-10% growth response. Comparisons are made with other published data to support this suggestion.
