1. 1. Wing epidermis from diapausing and non-diapausing silkmoths (Antheraea pernyi) was assayed for NADH [nicotinamide adenine dinucleotide (reduced form)] oxidase, NADH- and succinate-cyctochrome c reductases, and cytochrome c oxidase. 2. 2. Diapau

When juvenile hormone analogues were applied to developing embryos of Lygaeus kalmii, at the approximate time of blastokinesis, morphological effects were observed in larval life as well as at the time of metamorphosis. Of particular interest was the

1. The localization and properties of cholinesterase in the brain of the Cecropia silkmoth were investigated by histochemical and quantitative spectrophotometric methods utilizing acetylthiocholine as substrate.2. During pupal diapause, substantial a

The remarkable control of insect growth by the hormone ecdyson is readily apparent in the events that transform a diapausing Cecropia pupa into a developing adult moth. The pupal diapause, as shown by Williams,' is a state of developmental arrest enf

The activities of four oxidative enzyme systems, including NADH oxidase, succinate-cytochrome c reductase, NADH-cytochrome c reductase, and cytochrome c oxidase, were compared in mitochondrial-microsomal preparations from wing epidermis and fat body

DURING recent years, dipterous larvae possessing giant polytene chromosomes have provided important new insight into developmental physiology at the sub-cellular level. This is in large measure attributable to the phenomenon of chromosomal ‘puffing

IN the ten years that have passed since Szent-Gyorgyi1 introduced the use of the glycerol-extracted muscle fibre, it has proved extremely useful for investigating the molecular events underlying muscular contraction. Usually, the fibre has been regar
