The Effect of Starvation on The Susceptibility of House Flies to Pyrethrum Sprays

Abstract

When houseflies (Musca domestica L.) are reared for use in fly spray tests,their susceptibility to pyrethrum sprays is not affected by starvation for shortperiods (which, in complete darkness, may exceed 12 hours), provided they aregiven access to food for a sufficient time, immediately prior to testing, to ensurethat all have had a recent feed when sprayed.
