A new subgenus, , in the genus Hreblay & L. Ronkay, 1998, is established and described for Himalaea (Macrohimalaea) batanga Saldaitis, Benedek & Volynkin, 2022 and for a new species, Himalaea (Macrohimalaea) silvana This new species is the type of the new subgenus. The new subgenus is distinct from the nominotypical one in having antennal pectination and its forewing shape and male genitalia. All four known adult specimens of the genus and their genitalia are illustrated and compared. Their collection localities are mapped.

is described from the Iberian Peninsula. Differential superficial, genital and genetic (barcode) characters from its closest Iberian and European relative species, (Hufnagel, 1766), are presented. Morphologically, the new species is best characterized in the male genitalia by the shape of the basal vesica and the presence of a median diverticulum and in the female genitalia by its comparatively long appendix bursae. The barcode of differs from those of related species and is assigned a unique BIN.

The fall armyworm Spodoptera frugiperda is a prime noctuid pest of maize on the American continents where it has remained confined despite occasional interceptions by European quarantine services in recent years. The pest has currently become a new invasive species in West and Central Africa where outbreaks were recorded for the first time in early 2016. The presence of at least two distinct haplotypes within samples collected on maize in Nigeria and São Tomé suggests multiple introductions into the African continent. Implications of this new threat to the maize crop in tropical Africa are briefly discussed.

Regions of southern Florida and southern Texas (extending into Mexico) provide the overwintering source populations for virtually all fall armyworm infestations affecting the continental United States. Understanding how these migratory populations annually disperse is important to predict and control infestations by this specific pest and to more generally investigate the environmental factors that influence the long-distance movements of flying insects. The two overwintering locations are associated with differences in the distribution of certain mitochondrial haplotypes that overlap in the region near the border separating the states of Alabama and Georgia. This provided an opportunity to test the resolution of the haplotype method by comparisons between smaller geographical areas and shorter time frames than previously examined. Correspondences were found between trap-capture numbers, fall armyworm strain proportions, and haplotype ratios calculated for individual counties and within season time periods that were generally consistent with expectations, providing confidence that those population movements could be accurately inferred. The comparison of haplotype distributions identified a migratory boundary separating the Texas and Florida populations coincident with the eastern edge of the Apalaehicola-Chattahoochee-Flint River basin. Calculations of strain numbers based on genetic markers revealed similarities and differences in strain population dynamics that can be applied to study the migratory behavior of fall armyworm subpopulations. The use of this methodology for the detailed mapping of migratory pathways and the identification of factors that influence the direction and extent of pest migration are discussed.

Ctenoplusia agnata (Staudinger) (Lepidoptera: Noctuidae) is an important polyphagous pest in East Asia. Previous studies showed that C. agnata moths possesses the potential to undertake long-distance migration; however, knowledge of whether or not the migration of C. agnata moths is a regular ecological behavior and what the pattern of seasonal migrations is in case of regular migration is currently lacking. In the current study, systemic monitoring of population dynamics of C. agnata was conducted by a searchlight trap on an island in the center of Bohai gulf in northern China, during 2003-2013. Our results provided strong evidence for the hypothesis that C. agnata is one of the pest species undertaking regular high altitude long-distance migration and we have depicted the seasonal migration pattern over the Bohai Sea. The first capture of C. agnata generally appeared in late April and early May, then the daily number of catches increased to high levels in late July and formed two waves of migration through August and early September, and finally, the moths disappeared in late October. The mean time from the earliest trapping to the latest trapping within a year was 141.0 plus or minus 3.0 days. The index of ovarian development of female C. agnata showed seasonal variability and suggested that its migratory flight may be independent of the degree of ovarian development and mating status. In addition, strong migration events took place in 2003, 2004, 2008, and 2010 (annual sum of catches >10,000). The research result from this work is helpful for understanding the occurrence regularity of C. agnata and developing an integrated pest management strategy.

The Noctuidae are a family with many species worldwide, but in Mexico, there is little information about their species richness despite noctuids being very important pests in agriculture. With data obtained from fieldwork and specimens from the Entomological Collection of Universidad de Guanajuato, a list of species found in Guanajuato was made, taking into account distribution and biogeographic affinity data.

Insect outbreaks can have important consequences for tundra ecosystems. In this study, we synthesise available information on outbreaks of larvae of the noctuid moth Eurois occulta in Greenland. Based on an extensive dataset from a monitoring programme in Kobbefjord, West Greenland, we demonstrate effects of a larval outbreak in 2011 on vegetation productivity and CO sub(2) exchange. We estimate a decreased carbon (C) sink strength in the order of 118-143 g C m super(-2), corresponding to 1210-1470 tonnes C at the Kobbefjord catchment scale. The decreased C sink was, however, counteracted the following years by increased primary production, probably facilitated by the larval outbreak increasing nutrient turnover rates. Furthermore, we demonstrate for the first time in tundra ecosystems, the potential for using remote sensing to detect and map insect outbreak events.

A new species of the genus Bombyciella Draudt, 1950, Bombyciellalinzhiensis sp. nov., is described from the Linzhi (Nyingchi) Prefecture in southern Xizang (China), following a diagnostic comparison with B.talpa Draudt, 1950 and B.antra Saldaitis, Benedek, Behounek & Stüning, 2014. The adults and the male genitalia of the new and related species are illustrated.A new species of the genus Bombyciella Draudt, 1950, Bombyciellalinzhiensis sp. nov., is described from the Linzhi (Nyingchi) Prefecture in southern Xizang (China), following a diagnostic comparison with B.talpa Draudt, 1950 and B.antra Saldaitis, Benedek, Behounek & Stüning, 2014.

Goldstein, is described to accommodate Druce, 1898. Recent discovery of its larva, which has been recorded eating foliage of species in six families of leptosporangiate ferns, suggest a possible subfamily assignment within the Eriopinae, but this cannot be substantiated based on adult morphology. This species has no obvious close relatives either among the core noctuid pteridivore genera currently recognized in the Eriopinae (e.g., Hübner, [1821]), nor among genera more recently discovered to be fern-feeders but which remain incertae sedis with respect to subfamily (e.g., Druce, 1908, Schaus, 1911). The recorded foodplant profile is similar to that of another ambiguously placed Nearctic species (Guenée, 1852) (Noctuidae: Noctuinae: Xylenini, incertae sedis) with which it shares no obvious synapomorphies.
