description: Lumbar spinal stenosis (LSS) has a substantial impact on mobility, autonomy, and quality of life. Previous reviews have demonstrated inconsistent results and/or have not delineated between specific nonsurgical interventions. The purpose of this systematic review is to assess the effectiveness of interventions in the management of LSS. Eligible studies were randomized controlled trials (RCTs) or prospective studies, included patients with LSS, assessed the effectiveness of any interventions (rehabilitation, surgical, injection, medication), included at least two intervention groups, and included at least one measure of pain, disability, ambulation assessment, or LSS-specific symptoms. Eighty-five articles met inclusion criteria. Meta-analyses were conducted across outcomes. Effect sizes were calculated using Hedge’s g and reported descriptively. Formal grading of evidence was conducted. Meta-analysis comparing rehabilitation to no treatment/placebo demonstrated significant effects on pain favoring rehabilitation (mean difference, MD −1.63; 95% CI: −2.68, −0.57; I2 = 71%; p = .002). All other comparisons to no treatment/placebo revealed nonsignificant findings. The level of evidence ranged from very low to high for rehabilitation and medication versus no treatment/placebo for pain, disability, ambulation ability, and LSS symptoms. Although the findings of this review are inconclusive regarding superiority of interventions, this accentuates the value of multimodal patient-centered care in the management of patients with LSS.

description: Complex orthogonal design (COD) with parameter $[p, n, k]$ is a combinatorial design used in space-time block codes (STBCs). For STBC, $n$ is the number of antennas, $k/p$ is the rate, and $p$ is the decoding delay. A class of rate $1/2$ COD called balanced complex orthogonal design (BCOD) has been proposed by Adams et al., and they constructed BCODs with rate $k/p = 1/2$ and decoding delay $p = 2^m$ for $n=2m$. Furthermore, they prove that the constructions have optimal decoding delay when $m$ is congruent to $1$, $2$, or $3$ module $4$. They conjecture that for the case $m \equiv 0 \pmod 4$, $2^m$ is also a lower bound of $p$. In this paper, we prove this conjecture.

Mangelt es an geeigneten Vorgehensweisen, ist die Bewältigung häufig mit mehreren Bearbeitungsanläufen verbunden. Erkennt man bei einem neuen Problem eine strukturelle Ähnlichkeit zu einem bereits bekannten, kann es daher naheliegend erscheinen, die Lösungsbemühungen unter Nutzung bekannter und bereits bewährter Vorgehensweisen abzukürzen. Jedoch muss das, was für die Bewältigung eines Problems funktioniert hat, nicht zwangsläufig auch für andere Probleme zielführend sein.
Improved predictions for $μ\to e$ conversion in nuclei and Higgs-induced lepton flavor violation

description: Compared to $μ\to e γ$ and $μ\to e e e$, the process $μ\to e$ conversion in nuclei receives enhanced contributions from Higgs-induced lepton flavor violation. Upcoming $μ\to e$ conversion experiments with drastically increased sensitivity will be able to put extremely stringent bounds on Higgs-mediated $μ\to e$ transitions. We point out that the theoretical uncertainties associated with these Higgs effects, encoded in the couplings of quark scalar operators to the nucleon, can be accurately assessed using our recently developed approach based on $SU(2)$ Chiral Perturbation Theory that cleanly separates two- and three-flavor observables. We emphasize that with input from lattice QCD for the coupling to strangeness $f_s^N$, hadronic uncertainties are appreciably reduced compared to the traditional approach where $f_s^N$ is determined from the pion--nucleon $σ$-term by means of an $SU(3)$ relation. We illustrate this point by considering Higgs-mediated lepton flavor violation in the Standard Model supplemented with higher-dimensional operators, the two-Higgs-doublet model with generic Yukawa couplings, and the Minimal Supersymmetric Standard Model. Furthermore, we compare bounds from present and future $μ\to e$ conversion and $μ\to e γ$ experiments.

The method is applied to the ISHEs of Bi-doped Cu and Pt. The derived expression of ISHE for the loop structure can relate the charge current flowing into the loop to the spin Hall angle of the SHE material and the resistance of the loop.

description: Single GaN nanowires formed spontaneously on a given substrate represent nanoscopic single crystals free of any extended defects. However, due to the high area density of thus formed GaN nanowire ensembles, individual nanowires coalesce with others in their immediate vicinity. This coalescence process may introduce strain and structural defects, foiling the idea of defect-free material due to the nanowire geometry. To investigate the consequences of this process, a quantitative measure of the coalescence of nanowire ensembles is required. We derive objective criteria to determine the coalescence degree of GaN nanowire ensembles. These criteria are based on the area-perimeter relationship of the cross-sectional shapes observed, and in particular on their circularity. Employing these criteria, we distinguish single nanowires from coalesced aggregates in an ensemble, determine the diameter distribution of both, and finally analyze the coalescence degree of nanowire ensembles with increasing fill factor.

description: Mathematische Objekte sind abstrakt und oftmals nicht sichtbar. Beispielsweise lassen sich Terme, Variablen und auch Gleichungen nur bedingt haptisch erfassen. Dennoch haben Schüler*innen individuelle Sichtweisen auf mathematische Objekte und ganz eigene Vorstellungen davon. Sfard (1987, S. 162) unterscheidet zwischen einer operationalen, prozessorientierten (‚operational conception‘) und einer strukturellen, produktorientierten Sichtweise (‚strutural conception‘) auf mathematische Objekte. Im Übergang von der Arithmetik zur Algebra ist diese Prozess-Produkt Dualität mathematischer Objekte eine besondere Herausforderung für Schüler*innen und ihre Lehrkräfte (vgl. Kieran, 2020). In mathematischen Argumenten bilden in der Regel mathematische Objekte und ihre Beziehungen den inhaltlichen Kern. Wie sich die Prozess-Produkt Dualität und damit eine prozess- oder produkthafte Deutung von mathematischen Objekten wiederum in mathematischen Argumentationen im Unterricht widerspiegelt und welche Bedeutung ihr dabei zukommt, wird in diesem Beitrag fokussiert. Herausforderungen, die sich für Lernende ergeben, werden benannt.

Nationale und internationale Studien (z. B. Herendiné-Kónya, 2015; Ulfig, 2013) zeigen, dass dies nicht immer gelingt, so dass bei Schüler*innen konzeptuelles Verständnis nicht ausreichend vorhanden ist und folglich auswendig gelernte Formel fehlerhaft angewendet werden (Herendiné-Kónya, 2015). Das heißt, die Schüler*innen haben vorrangig prozedurales Wissen erworben, aber das zugrundeliegende Konzept zur Begründung des Vorgehens, das insbesondere zur Lösung von Transferaufgaben notwendig ist, wird nicht verstanden. Dieser Beitrag stellt unterschiedliche Ansätze zur Flächenbestimmung vor, die den Aufbau von konzeptuellem Wissen unterstützen sollen.

Im Kontrast dazu stehen Ergebnisse, dass digitale Technologien im alltäglichen Schulunterricht – insbesondere für die Schülerhand – kaum genutzt werden (Eickelmann et al., 2019). Eine mögliche Ursache dafür könnte darin bestehen, dass Lehrkräfte nicht in ausreichendem Maß über das Wissen verfügen, das für die zielgerichtete Nutzung digitaler Technologien im Unterricht notwendig ist. Um dies aufzuklären, wird das von Lehrkräften für das Unterrichten mit interaktiven Arbeitsblättern zu funktionalen Zusammenhängen benötigte Wissen zusammengestellt und in einer Studie untersucht, inwiefern Lehramtsstudierende mit dem Fach Mathematik für die Sekundarstufen über dieses Wissen verfügen.

description: In the so-called ``yukawaon" model, the (effective) Yukawa coupling constants $Y_f^{eff}$ are given by vacuum expectation values (VEVs) of scalars $Y_f$ (yukawaons) with $3\times 3$ components. In the present model, all of the VEV matrices $\langle Y_f \rangle$ are given by a bilinear form of VEVs of flavons $Φ_f$, $\langle Y_f \rangle_i^{\ j} = k_f \langle Φ_f\rangle_{ik} \langle \barΦ_f\rangle^{kj}$, where $Φ_f$ is assigned to ${\bf 6}$ of U(3) family symmetry. As input parameters with family-number dependent values, we use only charged lepton mass values. Under this formulation, we can give reasonable values of quark and lepton masses and their mixings. A $CP$ violating phase $δ_{CP}^\ell=26^\circ$ in the lepton sector is predicted. The effective Majorana neutrino mass is also predicted.

title: Hermetic storage of dry soybean (Glycine max): creating an effective modified atmosphere using soaked grain as O₂ depletor
Creators: name: Taher, Hernán
name: Bartosik, Ricardo
Publisher: name: Julius Kühn-Institut
Year: 2018

description: Hermetic storage of grains and oilseed has been proposed as a solution for reducing food losses in developing countries. However, to obtain full benefit of the hermetic storage it is required to achieve a low O2 concentration (below 2%) or high CO2 concentration (above 20%). The gas concentration inside the hermetic container is the result of the balance between the respiration and gas exchange rates with the outside (permeability and leakage). When the grain is dry, an insufficient modification in the internal atmosphere is achieved (exchange rate higher than respiration rate), allowing insect development and, hence, grain losses. This study focuses in creating an effective modified atmosphere during the hermetic storage of dry soybean using soaked grain as O2 depletor. Three big bags with internal polyethylene liners of 70 µm thickness were filled with 590 kg of soybean (Glycine max, with 12.5% m.c.) and sealed. Gas concentration evolution was measured during 15 days (basal condition). Later, four plastic perforated bottles filled with of 4.3 kg of soaked soybean (44% m.c.) were inserted in each bag. The bags were re-sealed and gas concentration was measured during 45 days. Results indicated that the soaked soybean acted as an O2 depletor, reducing the gas concentration to 1% in only 8 days, and maintained below 1% during 45 days. This research indicated that a small portion of soaked grain (0.4% dry matter (d.m.)) can be used to generate an effective modified atmosphere to prevent biological activity in the entire grain mass. This is a simple and inexpensive approach to reduce food losses under low cost hermetic storage.

Navier-Stokes transport coefficients for driven inelastic Maxwell models

description: We calculate in this work the Navier-Stokes transport coefficients from the Boltzmann equation for $d$-dimensional inelastic Maxwell models. By granular gas we mean here a low density system of identical spheres that lose a fraction of their kinetic energy after collisions. In the present work, the granular gas is fluidized by the presence of a thermostat that aides the system to reach a steady state. The thermostat is composed by two terms: a random force and a drag force. The combined action of both forces, that act homogeneously on the granular gas, tries to mimic the interaction of the set of particles with a surrounding fluid. The Chapman-Enskog method is applied to solve the inelastic Boltzmann equation to first order in the deviations of the hydrodynamic fields from their values in the homogeneous steady state. Since the collisional cooling cannot be compensated locally for by the heat produced by the driving forces, the reference (zeroth-order) distribution function $f^{(0)}$ depends on time through its dependence on the granular temperature. To simplify the analysis and obtain explicit forms for the transport coefficients, the steady state conditions are considered. A comparison with previous results obtained for inelastic hard spheres is also carried out.

description: We propose an expanded spin-glass model, called the quantum Ghatak-Sherrington model, which considers spin-1 quantum spin operators in a crystal field and in a transverse field. The analytic solutions and phase diagrams of this model are obtained by using the one-step replica symmetry-breaking ansatz under the static approximation. Our results represent the splitting within one spin-glass (SG) phase depending on the values of crystal and transverse fields. The two separated SG phases, characterized by a density of filled states, show certain differences in their shapes and phase boundaries. Such SG splitting becomes more distinctive when the degeneracy of the empty states of spins is larger than one of their filled states.

description: Aufbauend auf den Impulsen aus dem Projekt Mathematik Neu Denken (Beutelspacher et al., 2012) wurde auch an der Goethe-Universität Frankfurt die gymnasiale Lehramtsausbildung im Fach Mathematik umgestaltet. Den Kern der Reform bildete dabei die neu konzipierte Vorlesung Entstehungsprozesse von Mathematik (siehe Weygandt, 2018; 2021): Diese Veranstaltung knüpfte inhaltlich an die Vorlesung Analysis I an und legte durch eine genetische Herangehensweise den Fokus auf die (Nach-)Entdeckung fachmathematischer Inhalte und die Vermittlung mathematischer Arbeitsweisen (Weygandt & Oldenburg, 2014; 2018). Die Studierenden lernten Mathematik als ein menschliches Produkt kennen und erlangten tiefer gehendes Konzeptverständnis. Die für sie ‚neue‘ Hochschulmathematik wurde eigentätig und in kooperativer Kleingruppenarbeit erkundet, wobei genuine mathematische Arbeitsweisen als eigener Lerngegenstand in den Mittelpunkt rückten. Insgesamt sollten Studierende stärker als zuvor die Gelegenheit bekommen, im Rahmen einer für sie bedarfsgerechten Fachausbildung ein facettenreiches und tragfähiges mathematisches Weltbild aufzubauen. In diesem Beitrag werden ausgewählte Ergebnisse der empirischen Begleitforschung des Projekts vorgestellt, für die ausführlichen methodischen Hintergründe sowie die Diskussion der Ergebnisse wird auf die entsprechenden Kapitel in Weygandt (2021) verwiesen.

description: Recently, a test was conducted in Italy for the evaluation of the biocidal efficacy of Nitrogen saturation (anoxic conditions). One application was carried out in a controlled atmosphere cell of a logistic center specialized in receiving, storing and shipping foodstuffs. The cell, circa 3682 m3 volume, with capacity of 752 big bags of fresh shelled hazelnuts on 4 height levels was saturated with Nitrogen (99,9%) and maintained at 15-18°C for 21 days. Five test species of insects Plodia interpunctella, Cadra cautella, Corcyra cephalonica, Tribolium confusum, Oryzaephilus surinamensis were observed at different development stages (egg, larva, adult). The target species were sorted in special biotest and inserted in the big bags to simulate an infestation. At the end of the exposure period the biotests were collected and analyzed. The treatment resulted sufficient to achieve a total control on eggs of Lepidoptera test species only. This result confirmed and integrates the available information in literature that showed the need of a longer minimum exposure period for total control of common stored pest insects.

description: Durch die digitale Transformation im Bildungsbereich und den damit verbundenen zunehmenden Einsatz digitaler Medien im Unterricht kommen auf Lehrpersonen viele verschiedene neue Herausforderungen zu. So fordert beispielsweise die Strategie der Kultusministerkonferenz zur „Bildung in der digitalen Welt“, dass „Lehrkräfte digitale Medien in ihrem jeweiligen Fachunterricht professionell und didaktisch sinnvoll nutzen sowie gemäß dem Bildungs- und Erziehungsauftrag inhaltlich reflektieren können“ (KMK, 2016, S. 25). Um diesen Aufgaben begegnen zu können, müssen angehende wie auch praktizierende Mathematiklehrer*innen ihre professionellen Kompetenzen im Umgang mit digitalen Medien und deren gezielten Einsatz in Lehr-Lernprozessen entwickeln bzw. weiterentwickeln. Die Förderung professioneller Digitalkompetenzen soll dabei laut dem Strategiepapier explizit in allen Phasen der Lehrer*innenbildung stattfinden, also im Studium, dem Vorbereitungsdienst sowie der Fort- und Weiterbildung. In diesem Beitrag wird ein Konzept zur Diskussion gestellt, welches im Kontext von digitalen Medien im Unterricht gezielt Personen aus der ersten und dritten Phase der Lehrer*innenbildung, also Studierende und praktizierende Lehrpersonen, zusammenbringt, um gemeinsam Kompetenzen aufzubauen.

description: Aus einer interaktionistischen Perspektive konstituieren sich Prozesse des Mathematiklernens in mathematischen Aushandlungsprozessen, in denen die Interaktionsteilnehmenden ihre mathematischen Interpretationen in der jeweiligen Situation kontinuierlich aufeinander abstimmen. Mathematiklernen wird demnach als ein sozialer Interpretationsakt verstanden, in dem Bedeutungen durch interaktive Aushandlungsprozesse konstruiert werden (Krummheuer & Brandt, 2001). Dieser Aushandlungsprozess kann in Form einer kollektiven Argumentation (Jung, 2019), zu einer wechselseitig zwischenzeitlich als geteilten Deutung – dem Deutungsinterim – konvergieren (Schütte et al., 2021, Tewes & Schütte, im Druck). Die Partizipation an diesen mathematischen Aushandlungsprozessen wird in der interaktionistischen Lerntheorie als konstitutive Bedingung für das Mathematiklernen gesehen (Krummheuer & Brandt, 2001; Jung, 2019; Schütte et al., 2021) und kann für jedes Individuum wiederum unterschiedlich sein.

description: A fundamental problem in network science is to predict how certain individuals are able to initiate new networks to spring up "new ideas". Frequently, these changes in trends are triggered by a few innovators who rapidly impose their ideas through "viral" influence spreading producing cascades of followers fragmenting an old network to create a new one. Typical examples include the raise of scientific ideas or abrupt changes in social media, like the raise of Facebook.com to the detriment of Myspace.com. How this process arises in practice has not been conclusively demonstrated. Here, we show that a condition for sustaining a viral spreading process is the existence of a multiplex correlated graph with hidden "influence links". Analytical solutions predict percolation phase transitions, either abrupt or continuous, where networks are disintegrated through viral cascades of followers as in empirical data. Our modeling predicts the strict conditions to sustain a large viral spreading via a scaling form of the local correlation function between multilayers, which we also confirm empirically. Ultimately, the theory predicts the conditions for viral cascading in a large class of multiplex networks ranging from social to financial systems and markets.

description: Experiments carried out to find the fumigant toxicity of three essential oils and their combinations from Murraya koenigii, Citrus reticulata, Curcuma longa on population buildup of Sitophilus oryzae, Rhyzopertha dominica, Tribolium castaneum in stored wheat at different days of infestation. The oil of M. koenigii, C. reticulata at 0.2% and M. koenigii+C. reticulata, M. koenigii+C. longa at 0.1% each were found highly effective against S. oryzae fumigated after 5, 10, 15 and 20 days. The oil of M. koenigii and C. reticulata at 0.2% M. koenigii+C. reticulata, M. koenigii+C. longa, C. reticulata+C. longa at 0.1% each and M. koenigii+C. reticulata+C. longa at 0.07% each were found highly effective against R. dominica fumigated after 5, 10, 15 and 20 days. Only M. koenigii at 0.2% was found highly effective against T. castaneum fumigated after 5, 10, 15 and 20 day. The fumigation of grain with M. koenigii at 0.2% completely suppress the infestation and weight loss when it was fumigated after 5, 10, 15 and 20 days while very low infestation and weight loss was observed in grain treated with M. koenigii +C. reticulata at 0.1% each and not affect the organoleptic properties and germination of wheat.

description: The insecticidal activity of essential oil vapors of Haplophyllum tuberculatum (Sapindales: Rutaceae) and Nepeta crispa (Lamiales: Lamiaceae) were evaluated on third instar larvae of Plodia interpunctella (Lepidoptera: Pyralidae) as one of the major insect pests of stored products. Essential oils of the plants were obtained using Clevenger-type water distillation. GC-MS analyses of the oils demonstrated that the main compounds of H. tuberculatum were ρ-menth-2-en-1-ol-cis (20.15 %), ρ-menth-2-en-1-ol-trans (16.92 %), trans-Piperitol (13.23 %), Piperitone (7.34 %) and cis-Piperitol (6.72 %). It is an important plant that has many medicinal properties. 1,8- Cineole (32.98 %), ß-Pinene (8.70 %), 4aa,7a,7aa-Nepetalactone (8.08 %) and 4aß,7a,7aß-Nepetalactone (6.1 %) were detected as the predominant component in N. crispa. The aerial parts of that are used in traditional medicine. The LC50 values were estimated after 24 hours for H. tuberculatum and N. crispa as 4.301 and 5.579 µl L-1 air, respectively. LC50 values were projected using probit analysis. Results on H. tuberculatum showed more toxicity against the Indian meal moth compared to the N. crispa. In conclusion, the essential oil of the two plants could have potential for application to stored grain and agricultural commodities to control of stored crop pests in IPM programs.

description: Das Bearbeiten von mathematischen Übungsaufgaben ist ein wichtiger Bestandteil des Mathematikstudiums. In universitären Veranstaltungen wird erwartet, dass Studierende die in der Vorlesung behandelten Sätze und Definitionen in ihren Bearbeitungen dieser Aufgaben nutzen. Um das Lernen der Studierenden beschreiben zu können, führten Tall und Vinner (1981) die Theorie des Concept Images und der Concept Definition ein. Untersuchungen zeigen, dass das individuelle Concept Image der Lernenden nicht immer zu der Concept Definition passt (z. B. ebd.). Inwiefern Studierende ihr Concept Image beim Bearbeiten von Aufgaben nutzen und inwiefern sie dieses mit einer formalen Aufgabenbearbeitung mit Bezug zur Concept Definition vernetzen, wurde in einer qualitativen Studie an der JLU Gießen untersucht. Um die bei der Aufgabenbearbeitung ablaufenden Prozesse angemessen beschreiben zu können, wurde die Theorie adaptiert und die Concept Definition um weitere formale Handlungen wie das deduktive Schließen mit Sätzen ergänzt (Utsch & Lengnink, in Druck). In der Studie wurden Lehramtsstudierende gebeten, vier Aufgaben zur Folgenkonvergenz mit der Methode des lauten Denkens zu bearbeiten. Die Lernprozesse der Studierenden beim Bearbeiten der Aufgaben wurden in einem zweistufigen Vorgehen ausgewertet: Zuerst wurde eine qualitative Inhaltsanalyse durchgeführt und die Codierung in sogenannten Prozessmatrizen visualisiert. Mithilfe dieser Prozessmatrizen konnten Transkripte ausgewählt werden, die mit einem interpretativen Vorgehen in Anlehnung an die Objektive Hermeneutik analysiert wurden. So konnten Praktiken der Aufgabenbearbeitungen rekonstruiert werden, die auf eine Vernetzung von Concept Image und Concept Definition hinweisen. Mit Praktiken sind keine einzelnen, individuellen Handlungen gemeint, sondern ein umfassenderes, in der Untersuchungsgruppe geteiltes und routiniertes Bündel von Aktivitäten (Reckwitz, 2003).

description: We consider the first-passage problem for N identical independent particles that are initially released uniformly in a finite domain Ω and then diffuse toward a reactive area Γ, which can be part of the outer boundary of Ω or a reaction centre in the interior of Ω. For both cases of perfect and partial reactions, we obtain the explicit formulas for the first two moments of the fastest first-passage time (fFPT), i.e., the time when the first out of the N particles reacts with Γ. Moreover, we investigate the full probability density of the fFPT. We discuss a significant role of the initial condition in the scaling of the average fFPT with the particle number N, namely, a much stronger dependence (1/N and 1/N² for partially and perfectly reactive targets, respectively), in contrast to the well known inverse-logarithmic behaviour found when all particles are released from the same fixed point. We combine analytic solutions with scaling arguments and stochastic simulations to rationalise our results, which open new perspectives for studying the relevance of multiple searchers in various situations of molecular reactions, in particular, in living cells.

description: By measuring energy spectra of the electron emission from a sharp tungsten tip induced by few-cycle laser pulses, the laser-field dependence of the emission mechanism was investigated. In strong laser fields, we confirm the appearance of laser-driven tunneling emission and find that it can be disentangled from the concomitant photo-excited electron emission, both temporally and spectrally, by the opening of a peculiar emission channel. This channel involves prompt laser-driven tunneling emission and subsequent laser-driven electron re-scattering off the surface, delayed by the electrons traveling far inside the metal before scattering. The quantitative understanding of these processes gives insights on attosecond tunneling emission from solids and should prove useful in designing new types of pulsed electron sources.

description: In this study, ozone gas at different concentrations (16.7, 33.3 and 66.6 mg/L) were exposed to all biological stages (egg, larva, pupa and adult) placed at top and bottom of the hazelnut for various exposure periods (2, 4 and 6 hours). In biological tests conducted in presence of hazelnuts, 100% mortalities of all biological stages of P. interpunctella placed at top of the commodity were obtained at tested ozone concentrations and exposure periods while it was easier to kill the adult and pupa stages that the larva and egg stages. While it was possible to kill 100% of the adults and pupae placed at bottom of the commodity at tested ozone concentrations and exposure periods, 100% mortality of the larvae and eggs were not obtained at any of the ozone treatments. Generally, the mortalities of all life stages of P. interpunctella placed at bottom of the commodity for ozone treatments were lower than those placed at top of the commodity. It was easy to kill the pupae and adults of P. interpunctella placed at bottom of the commodity while the ozone treatments resulted in low mortalities of the egg and larvae placed at bottom of the commodity. Just as 100% mortalities of the larva and adult stages were not obtained even at the highest ozone concentration for the longest exposure period. In conclusion, in this study, it was observed that ozone gas only at high concentrations can control all biological stages of P. interpunctella in hazelnut and therefore could have an alternative potential for methyl bromide in quarantine applications in short application period.
