Facultative diapause in the wax moth, Galleria mellonella, occurs in the final larval instar. Application of juvenile hormone analogs (JHAs) to the larvae of this species has similar effects to diapause, in terms of prolonged development of the larva

In this report, we show that α-amylase activity is rhythmic in the wild-type fruit fly Drosophila melanogaster, and that this rhythm exhibits the properties of a clock output. Moreover, the rhythm of amylase activity is accompanied by fluctuations i

Under continuous light (LL) of low intensity (up to 2.0 lux), the free-running period of the blow fly activity rhythm lengthened for flies whose initial τDD was less than about 25 h, but shortened for longer-period flies. Light intensity above about

The biogenic amine serotonin (5-HT) is a neuromodulator in both vertebrates and invertebrates. It has been shown that serotonin, apart from its distinct effects on behavior, also plays a morphoregulatory role during the ontogeny of the insect's nervo

The dichotomous spermatogenesis of many Lepidopterans results in the production of two types of sperm: eupyrene sperm possessing a cell nucleus which participates in fertilisation, and apyrene ones, which lose their nuclei during development and whos

During larval development of the greater wax moth, Galleria mellonella, genes of storage proteins LHP76 and LHP82 are tissue- and stage-specifically expressed. In this study, hormonal regulation of this expression has been investigated in vivo. Messe

SUMMARYRecent studies have demonstrated that the peripheral tissues of vertebrates and invertebrates contain circadian clocks; however, little is known about their functions and the rhythmic outputs that they generate. To understand clock-controlled

When one-day-old, last instar Galleria mellonella larvae are exposed to 18 degrees C they enter diapause and cease further development for several months. During diapause a group of proteins (72-84 kDa) synthesized in the fat body and secreted into t

Flies exhibit circadian rhythms in their locomotor activity and in the sensitivity of the visual system to light. In their visual system, circadian rhythms have been detected not only in the retina but also in the first optic neuropile, the lamina. I
