Rainfall and populations of the clover root borer, Hylastinus obscurus (Marsham), were artificially controlled in pots of red clover grown under shelters in the field. Populations of clover root borer were higher under dry conditions. Although yield losses were high in borer-infested pots, yield reductions were no greater under dry than under wet conditions.
