Burying beetles (Nicrophorus sp.) are necrophagous insects with developed parental care. Genome of Nicrophorus vespilloides has been recently sequenced, which makes them interesting model organism in behavioral ecology. However, we know very little about their physiology, including the functioning of their neuroendocrine system. In this study, one of the physiological activities of proctolin, myosuppressin (Nieve? MS), myoinhibitory peptide (Trica-MIP-5) and the short neuropeptide F (Nicve-sNPF) in N. vespilloides have been investigated. The tested neuropeptides were myoactive on N. vespilloides hindgut. After application of the proctolin increased hindgut contraction frequency was observed (EC50 value was 5.47 x 10-8 mol/L). The other tested neuropeptides led to inhibition of N. vespilloides hindgut contractions (Nicve-MS: IC50 = 5.20 x 10~5 mol/L;Trica-MIP-5: IC50 = 5.95 x 10-6 mol/L;Nicvc-sNPF: IC50 = 4.08 x 10-5 mol/L). Moreover, the tested neuropeptides were immunolocalized in the nervous system of N. vespilloides. Neurons containing sNPF and MIP in brain and ventral nerve cord (VNC) were identified. Proctolin-immunolabeled neurons only in VNC were observed. Moreover, MIP-immunolabeled varicosities and fibers in retrocerebral complex were observed. In addition, our results have been supplemented with alignments of amino acid sequences of these neuropeptides in beetle species. This alignment analysis clearly showed amino acid sequence similarities between neuropeptides. Moreover, this allowed to deduce amino acid sequence of N. vespilloides proctolin (RYLPTa), Nicve-MS (QDVDHVFLRFa) and six isoforms ofNicve-MIP (Nicve-MIP-1一 DWNRNLHSWa;Nicve-MIP-2—AWQNLQGGWa;Nicve-MIP-3—AWQNLQGGWa;Nicve-MlP-4—AWKNLNNAGWa;Nicve-MIP-5—SEWGNFRGSWa;Nicve-MIP-6— DPAWTNLKGIWa;and Nicve-sNPF—SGRSPSLRLRFa).

Impact of cold on the immune system of burying beetle, Nicrophorus vespilloides （Coleoptera： Silphidae）

Insect Science 2017年第3期24卷 443-454页

Insect overwintering is one of the most astonishing phases of the insect life cycle. Despite vast amounts of knowledge available about the physiological mechanisms of this phenomenon, the impact of stress factors on insect immune system functioning during the winter is still unknown. The aim of this study is to analyze how low temperatures influence the immune system of the beetle Nic＇rophorus vespilloides. The results show that the beetle＇s immune system is differently modulated by cold induced in laboratory settings than that which occurs in natural conditions, Among beetles cultured in conditions similar to summer, low temperatures, did not influence the number of circulating haemocytes, phenoloxidase activity, haemocytes morphology, and percentage ratio of haemocyte types. In these beetles, differences were noted only in the ability of haemocytes to perform phagocytosis. Individuals acclimated in natural conditions in autumn had a higher level of humoral response and a different percentage ratio of haemocyte types. During the winter period, the number of haemocytes in the beetles decreased, but the percentage ratio of phagocytic haemocytes increased. Furthermore, we noted an increase of phenoloxidase activity. Our study also showed mitotic divisions ofhaemocytes in haemolymph collected from burying beetles after cold exposure and from burying beetles collected from natural conditions during autumn and winter. Differences in response to low temperatures in laboratory conditions and the natural environment suggest that the simultaneous presence of other stress factors during winter such as desiccation and starvation have a significant influence on the activity of burying beetle＇s immune system.

Insect Science 2011年第2期18卷 160-165页

作者： grzegorz rosinski Ignacy Korczynski Malgorzata Slocinska Robert Kuzminski Department of Animal Physiology and Development Poznen University Poznan Department of Forest Entomology Agricultural University of Poznan Poznan Poland

The peptides proctolin, crustacean cardioactive peptide （CCAP） and FMRFamide, which are known to modulate insect muscle contractions, were assayed for their action on oviduct contractions in Hylobius abietis. A video microscopy technique and computer-based method of data acquisition and analysis were used to investigate the effects of theses peptides on spontaneous contractions of continuously perfused oviducts. All three peptides tested stimulate spontaneous contraction activity of the pine weevil oviduct, increasing the frequency and amplitude of phasic contractions in a dose-dependent manner. Proctolin is more potent as a stimulator than CCAR For proctolin a threshold response of oviduct muscles is at concentration of peptide 10-11-10^-10mol/L and for CCAP at concentration range 10-10-10-9 mol/L. FMRFamide exerts a weak stimulatory effect on the oviduct, and at higher concentrations of the peptide （above 10.8 mol/L）. The peptides exert different responses on oviduct contractions and they may play a role as functional regulators in such processes as egg movement and oviposition.

A fire alarm system(FAS)is a system comprising signalling-alarm devices,which automatically detect and transmit information about fire,but also receivers of fire alarms and receivers for damage signals.Fire alarm systems function in different environmental conditions.During operation they should be in state of fitness.This is determined by the reliability of the assembled units and rational management of the operation process.Therefore a reliability and operational analysis of fire alarm systems as a whole is essential.This article presents an authorial model and an operational and reliability analysis of FAS,which is exploited in a transport building.It also demonstrates relationships occurring in the analysed system,where to an addressable fire alarm central unit with detection loops and control-monitoring loops alarm device lines(with monitored relay outputs for actuation of alarm-signalling devices)were connected.Research and analysis of results for representative FAS,which were exploited in similar environmental conditions,were conducted in order to determine operational and reliability parameters of the investigated system.FAS computer simulation was run during the time t=1 year of safety system operation.This led to the calculation of the probability value of the analysed FAS staying in the examined operational states.

ON THE ROLE OF SULFATE ION IN THE ATMOSPHERE

Acta meteorologica Sinica 1994年第4期8卷 498-504页

作者： J.rosinski C.T.Nagamoto National Center for Atmospheric Research National Oceanic and Atmospheric Administration

Drop freezing experiments with ammonium sulfate water solutions have shown the existence of the temperature maxima that are a function of the salt concentration.The maxima were:-12℃ for 10-4 M solution on filter,-9℃ for 10^(-4) to 10^(-3)M solution in contact with particles of continental origin,and -4℃ for 10^(-4) M solution in contact with particles of marine origin. It was speculated that the presence of ice-forming nuclei active at high temperature (-4℃) should extend the for- mation of ice in clouds toward lower latitudes,increase their albedos,and provide additional cooling during daytime for the earth.The microphysics of clouds must be included in studying climate.

Nucleation of ice by contact takes place when an aerosol particle collides with asurface of supercooled water drop.Aerosol particle may either bounce off the watersurface or be captured on it.McCully et al.(1956) and rosinski et al.(1963) have shownthat capture of hydrophilic particles was four times larger than of hydrophobic ones.Hydrophobic aerosol particles will nucleate ice preferentially during the brief time ofcontact when they bounce off the surface.Patricles that become captured on the surfacewill float and produce clusters that may nucleate ice at some later time (delayed on surface

Cloud condensation nuclei(CCN)constitute a reservoir of latent ice-forming nuclei(IFN)active by conden sation-followed-by-freezing and by sorption.Two classes of aerosol particles active as IFN by sorption were found.The first produces IFN concentrations which are dependent on temperature only.The IFN concen- tration consecutively increases with lowering of temperature and does not respond to the increasing partial water vapor pressure.The second produces IFN concentrations which are dependent on partial water vapor pressure only,The IFN concentration consecutively decreases with decreasing of the partial water vapor pres- sure that takes place with the lowering temperature. Sulfates(mostly ammonium sulfate)constitute an integral part of IFN active by condensation-followed-by- freezing and by sorption.Backward isentropic air parcel trajectories linked polluted air rich in sulfates and clean air with high and low concentrations of IFN active by condensation-followed-by-freezing at-19.7℃ and S_w=0.1%. The experiments were performed in a dynamic filter processing chamber with aerosol particles collected on membrane filters.
