“…Of particular relevance to the present study, dopamine and serotonin levels have been shown to diverge between diapausing and non‐diapausing groups in some butterfly and moth species. In larvae of a fellow pierid butterfly, the large cabbage white ( Pieris brassicae ), the amount of dopamine by the end of the photosensitive period under short‐day light treatment was twice as high as under long‐day treatment, mostly because catabolism of dopamine had ceased to occur (Isabel et al., ). Dopamine levels were also higher in diapausing individuals during the pupal stage, and were maintained at high levels until the termination of diapause.…”

“…The validity of this model rests on the identification of biomolecules involved in the cascade and in showing how concentration levels of end products can lead to the onset of diapause. Studies on variation in monoamine concentration carried out in the large cabbage white butterfly ( Pieris brassicae ), the silkworm ( Bombyx mori ) and the Chinese oak silkmoth ( Antheraea pernyi ) suggest that dopamine, an amine neurotransmitter and neuromodulator whose concentration varies according to light conditions, is highly implicated in processes leading to, maintaining, and terminating diapause (Isabel, Gourdoux, & Moreau, ; Noguchi & Hayakawa, ; Wang, Egi, Takeda, Oishi, & Sakamoto, ). A study based on the cotton bollworm ( Helicoverpa armigera ) associated diapause to reduced tricarboxylic acid activity (Xu, Lu, & Denlinger, ), and a recent investigation of the metabolome in green‐veined whites ( Pieris napi ) found a link between diapause termination and alanine concentration (Lehmann et al., ).…”

Gene expression profiling across ontogenetic stages in the wood white (Leptidea sinapis) reveals pathways linked to butterfly diapause regulation

In temperate latitudes, many insects enter diapause (dormancy) during the cold season, a period during which developmental processes come to a standstill. The wood white (Leptidea sinapis) is a butterfly species distributed across western Eurasia that shows photoperiod-induced diapause with variation in critical day-length across populations at different latitudes. We assembled transcriptomes and estimated gene expression levels at different developmental stages in experimentally induced directly developing and diapausing cohorts of a single Swedish population of L. sinapis to investigate the regulatory mechanisms underpinning diapause initiation. Different day lengths resulted in expression changes of developmental genes and affected the rate of accumulation of signal molecules, suggesting that diapause induction might be controlled by increased activity of monoamine neurotransmitters in larvae reared under short-day light conditions. Expression differences between light treatment groups of two monoamine regulator genes (DDC and ST) were observed already in instar III larvae. Once developmental pathways were irreversibly set at instar V, a handful of genes related to dopamine production were differentially expressed leading to a significant decrease in expression of global metabolic genes and increase in expression of genes related to fatty acid synthesis and sequestration. This is in line with a time-dependent (hour-glass) model of diapause regulation where a gradual shift in the concentration of monoamine neurotransmitters and their metabolites during development of larvae under short-day conditions leads to increased storage of fat, decreased energy expenditures, and ultimately developmental stasis at the pupal stage.

“…The vitamin B6 derivative pyridoxal 5′-phosphate acts as a coenzyme and participates in the biosynthesis of some neurotransmitters, such as serotonin, dopamine, and GABA [12]. Biogenic amine neurotransmitters in hemolymph, including serotonin and dopamine, have been shown to be involved in insect diapause in Mamestra brassicae and in Pieris brassicae [13, 14]. In the middle stage of the sixth instar, GABA was only detected in diapause-destined larval hemolymph.…”

Proteomic and metabolomic profiles of larval hemolymph associated with diapause in the cotton bollworm, Helicoverpa armigera

BackgroundDiapause is programmed developmental arrest coupled with the depression of metabolic activity and the enhancement of stress resistance. Pupal diapause is induced by environmental signals and is prepared during the prediapause phase. In the cotton bollworm, Helicoverpa armigera, the prediapause phase, which contains two sub-phases, diapause induction and preparation, occurs in the larval stage. Here, we performed parallel proteomic and metabolomic analyses on H. armigera larval hemolymph during the prediapause phase.ResultsBy two-dimensional electrophoresis, 37 proteins were shown to be differentially expressed in diapause-destined larvae. Of these proteins, 28 were successfully identified by MALDI-TOF/TOF mass spectrometry. Moreover, a total of 22 altered metabolites were found in diapause-destined larval hemolymph by GC-MS analysis, and the levels of 17 metabolites were elevated and 5 were decreased.ConclusionsThe proteins and metabolites with significantly altered levels play different roles in diapause-destined larvae, including diapause induction, metabolic storage, immune response, stress tolerance, and others. Because hemolymph circulates through the whole body of an insect, these differences found in diapause-destined larvae most likely correspond to upstream endocrine signals and would further influence other organ/tissue activities to determine the insect’s fact: diapause or development.Electronic supplementary materialThe online version of this article (doi:10.1186/1471-2164-14-751) contains supplementary material, which is available to authorized users.

“…Dopamine and melatonin appeared to play antagonistic roles in the photoperiodism of this species. Several studies have reported that elevated dopamine levels may induce diapause in some insects (Noguchi & Hayakawa 1997;Košt'ál et al 2000;Isabel et al 2001). Dopamine may be a common transmitter that induces and maintains diapause in insects.…”

The present study investigated the functional involvement of melatonin and dopamine in photoperiodism to terminate pupal diapause in the Chinese oak silkmoth, Antheraea pernyi (Lepidoptera: Saturniidae). Diapause in this long‐day (short‐night) species is maintained during long nights and can be terminated by exposure to a short‐night photoperiod. We observed the effects of melatonin and dopamine and their receptor antagonists on diapause pupae. Melatonin and flupentixol, a dopamine receptor antagonist, terminated pupal diapause even under long‐night photoperiods. Dopamine and luzindole, a melatonin receptor antagonist, retarded adult emergence during short nights, whereas melatonin advanced the timing of adult emergence under the short‐night photoperiod in a manner dependent on the number of injections. The results of the day‐length extension experiment indicated that a change in the photoperiod was immediately detected as mRNA expression of the rate‐limiting enzyme of melatonin production. These findings suggest that the melatonin pathway transmits information on the photoperiod to terminate the pupal diapause of A. pernyi. The melatonin pathway also inhibited the dopamine production system, and the dopamine pathway inhibited the melatonin production system. We propose an insect model of the photoperiodic counter driven by mutual inhibition between the melatonin and dopamine pathways.
