羽化后不久，大脑间部被完全破坏，极大地减少了卵子的产量，阻止了卵子的沉积，并抑制了性感受性。部分破坏并没有阻止交配和产卵，但交配不再对产卵和产卵产生刺激作用。大脑似乎是交配刺激的正常目标，而PI是获得由神经分泌物质介导的刺激的必要继电器。一些部分切除的处女的卵巢产量增加。大脑中的一个抑制中心可能被抑制了。
Complete destruction of the pars intercerebralis [PI] very soon after emergence strongly reduced egg production, prevented egg deposition and inhibited sexual receptivity. Partial destruction did not prevent copulation and oviposition, but mating had no longer a stimulating effect on egg production nor on egg deposition. The brain seems to be the normal target for mating stimuli, and the PI the necessary relay for obtaining the stimulation which is mediated by neurosecretory material. An increase in ovarian production occurred in some partially parsectomized virgin females. An inhibitory center in the brain was probably suppressed.
