Notes on the Life cycle of \u3ci\u3eNemoria Rubrifrontaria\u3c/i\u3e (Lepidoptera: Geometridae)

(excerpt) While surveying for insect pests of sweet fern, Myrica aspleniifolia L., two unidentified eggs were detected on foliage samples collected in June 1972 near Barton City, Alcona County, Michigan. the eggs were transferred to petri dishes with sweet fern foliage for rearing. Subsequently, one of the larvae that emerged was reared to adulthood and identified as Nemoria rubrifrontaria Packard. This note describes the life cycle of this insect

Records for Bittacus Hangingflies and Panorpa Scorpionflies (Mecoptera: Bittacidae and Panorpidae) in Florida

We provide new county records for four species of panorpids (Panorpa americana Swederus, Panorpa lugubris Swederus, Panorpa sp. undetermined, and one undescribed species from the Panorpa rufescens Rambur species group) and two species of bittacids (Bittacus pilicornis Westwood, Bittacus punctiger Westwood), and call attention to a previously published county record for another species, Panorpa rufa Gray, in Florida. Additionally, we reject a previously published record for the scorpionfly Panorpa claripennis Hine in Florida, which we overlooked in our 2008 preliminary checklist of Florida mecopterans. The record for P. lugubris in Miami-Dade County is the southernmost record for any panorpid in the continental United States

Life History, Damage, and Gall Development of the Gall Midge, \u3ci\u3eNeolasioptera Brevis\u3c/i\u3e (Diptera: Cecidomyiidae), Injurious to Honeylocust in Michigan

Neolasioptera brevis is univoltine in Michigan. Adults issue in late spring, and females deposit eggs in rows on the lower side of young shoots of honeylocust. Larval eclosion occurs shortly after: there are three larval instars. The gall is polythalamous and may have 20 or more larvae. The third-instar larvae overwinter, and pupation occurs in spring. The gall injury kills sorne shoots, but most damage is cosmetic. One can monitor for adult emergence in late April or May by observing cast pupal cases protruding from the gall. Control, if needed, should be directed at adults

Dark matter and neutrino masses in the R-parity violating NMSSM

The R-Parity symmetry Violating (RPV) version of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) is attractive simultaneously with regard to the so-called mu-problem and the accommodation of three-flavor neutrino data at tree level. In this context, we show here that if the Lightest Supersymmetric Particle (LSP) is the gravitino, it possesses a lifetime larger than the age of the universe since its RPV induced decay channels are suppressed by the weak gravitational strength. This conclusion holds if one considers gravitino masses ~ 10^2 GeV like in supergravity scenarios, and is robust if the lightest pseudoscalar Higgs field is as light as ~ 10 GeV [as may occur in the NMSSM]. For these models predicting in particular an RPV neutrino-photino mixing, the gravitino lifetime exceeds the age of the universe by two orders of magnitude. However, we find that the gravitino cannot constitute a viable dark matter candidate since its too large RPV decay widths would then conflict with the flux data of last indirect detection experiments. The cases of a sneutrino LSP or a neutralino LSP as well as the more promising gauge-mediated supersymmetry breaking scenario are also discussed. Both the one-flavor simplification hypothesis and the realistic scenario of three neutrino flavors are analyzed. We have modified the NMHDECAY program to extend the neutralino mass matrix to the present framework.Comment: Latex file, 23 pages, 7 figures.

SUSY radiative corrections on mu-tau neutrino refraction including possible R-parity breaking interactions

In this paper we investigate the one-loop radiative corrections to the neutrino indices of refraction from supersymmetric models. We consider the Next-to Minimal Supersymmetric extension of the Standard Model (NMSSM) which happens to be a better supersymmetric candidate than the MSSM for both theoretical and experimental reasons. We scan the relevant SUSY parameters and identify regions in the parameter space which yield interesting values for V_{mu tau}. If R-parity is broken there are significant differences between MSSM and NMSSM contributions contrary to the R-parity conserved case. Finally, for a non-zero CP-violating phase, we show analytically that the presence of V_{mu tau} will explicitly imply CP-violation effects on the supernova electron (anti-) neutrino fluxes.Comment: 23 pages, 15 figures; v2: typos and 5 figures correcte

Near-infrared spectropolarimetry of a delta-spot

Sunspots harboring umbrae of both magnetic polarities within a common penumbra (delta-spots) are often but not always related to flares. We present first near-infrared (NIR) observations (Fe I 1078.3 nm and Si I 1078.6 nm spectra) obtained with the Tenerife Infrared Polarimeter (TIP) at the Vacuum Tower Telescope (VTT) in Tenerife on 2012 June 17, which afford accurate and sensitive diagnostics to scrutinize the complex fields along the magnetic neutral line of a delta-spot within active region NOAA 11504. We examine the vector magnetic field, line-of-sight (LOS) velocities, and horizontal proper motions of this rather inactive delta-spot. We find a smooth transition of the magnetic vector field from the main umbra to that of opposite polarity (delta-umbra), but a discontinuity of the horizontal magnetic field at some distance from the delta-umbra on the polarity inversion line. The magnetic field decreases faster with height by a factor of two above the delta-umbra. The latter is surrounded by its own Evershed flow. The Evershed flow coming from the main umbra ends at a line dividing the spot into two parts. This line is marked by the occurrence of central emission in the Ca II 854.2 nm line. Along this line, high chromospheric LOS-velocities of both signs appear. We detect a shear flow within the horizontal flux transport velocities parallel to the dividing line.Comment: 4 pages, will appear as Letter in Astronomy & Astrophysic

Was there an ‘Industrious Revolution’ before the Industrial Revolution? An Empirical Exercise for England, c. 1300-1830

It is conventionally assumed that the pre-modern working year was fixed and that consumption varied with changes in wages and prices. This is challenged by the twin theories of the ‘industrious’ revolution and the consumer revolution, positing a longer working year as people earned surplus money to buy novel goods. In this study, we turn the conventional view on its head, fixing consumption rather than labour input. Specifically, we use a basket of basic consumption goods and compute the working year of rural and urban day labourers required to achieve that. By comparing with independent estimates of the actual working year, we find two ‘industrious’ revolutions among rural workers; both, however, are attributable to economic hardship, and we detect no signs of a consumer revolution. For urban labourers, by contrast, a growing gap between their actual working year and the work required to buy the basket provides great scope for a consumer revolution.Consumer Revolution; Cost-of-Living Index; Day Wages; ‘Industrious’ Revolution; Industrial Revolution; Labour Supply; Standard of Living
