Abstract: 
The 4th instar larvae of the silkworm, bombyx mori L, when treated with anti-juvenile hormone (Jinlu) had its larval period extended by 2 days and the total larval period shortened by about 4 days. The conversion ratio of tetramolters into trimolters was 100%. But anti-juvenile hormone administration to the 5th instar larvae lengthened the silkworm age by one day. When anti-juvenile hormone was administered, we could find many neurosecretory granules of the brain transferred to the cells of the corpora allata, but there was little endoplasmic reticulum. In the prothoracic gland, the micropile edge was clear and there were large nucleoli, mitochondria and endoplasmic reticulum. This study was carried out to show that anti-JH compound inhibits the secretion of Juvenile hormone in silkworm bombyx mori L. The investigation revealed that the anti-juvenile hormone inhibited the secretion of corpora allata and initiated the activity of the prothoracic gland.
