AbstractThe fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), has become a major threat in maize cultivation since its invasion to India in 2018. The humpbacked fly, Megaselia scalaris (Loew) (Diptera: Phoridae), was recorded as a laboratory parasitoid of FAW, for the first time in India. Initially, 30–40 maggots of M. (M) scalaris emerged out from the dead pre-pupa and pupa of laboratory-reared FAW. The fly laid up to 15 eggs on the outer surface of 6th instar larva or pre-pupa of the FAW. The incubation period was 1–2 days. The fly had 3 larval instars which lasted 3–4 days and a pupal period of 10–11 days. The adults survived for 6–7 days.

RESUMO - O objetivo foi avaliar a infestação, o parasitismo de ovos e danos da lagarta-do-cartucho, Spodoptera frugiperda (J. E. Smith), e da lagarta-da-espiga, Helicoverpa zea (Boddie), em cultivares de milho: variedade crioulo (Lombo Baio), híbrido convencional (Semilha S395) e híbrido geneticamente modificado (Bt) (TC1507 Herculex I ®, Cry1F). O experimento foi conduzido em Santa Maria-RS, no período de segunda safra de 2014. O delineamento foi de blocos ao acaso, com três tratamentos e quatro repetições. Foram registrados os danos, o número de lagartas, de posturas e o parasitismo em ovos da lagarta-do-cartucho, dos 9 aos 72 dias após a emergência das plantas (DAE). A infestação da lagarta-da-espiga e o parasitismo de ovos foram registrados dos 67 aos 101 DAE. Os danos causados pela lagarta-do-cartucho foram semelhantes entre milho crioulo e convencional, os quais foram mais elevados do que no milho geneticamente modificado Bt. O número médio de lagartas-do-cartucho foi maior em milho crioulo. A média do número total de lagartas-da-espiga foi semelhante entre milho crioulo e convencional e superior à do Bt. Foi registrado o parasitismo de ovos para a lagarta-da-espiga por Trichogramma pretiosum Riley, nas três cultivares avaliadas, com porcentagens semelhantes entre milho crioulo e convencional e superior em milho Bt. Palavras-chave: Spodoptera frugiperda, Helicoverpa zea, Trichogramma pretiosum, Zea mays, manejo de pragas. INFESTATION IN INLANDRACE, CONVENTIONAL AND TRANSGENIC CORN BY FALL ARMYWORM AND CORN EARWORM, AND EGG PARASITISM  ABSTRACT - The objective of the work was to estimate the infestation and eggs parasitism of fall armyworm (J. E. Smith) and corn earworm (Boddie), in three corn varieties: landrace (LomboBaio), conventional hybrid (Semilha S395) and genetically modified hybrid (Bt) (TC1507 Herculex I ®, Cry1F). The experiment was carried out in Santa Maria-RS, during the second-season corn crop, in 2014. The experimental design was a completely randomized block with three treatments, and four replicates. We evaluated the damages, number of larvae, number of eggs and fall armyworm egg parasitism from 9 to 72 days after emergence (DAE). The infestation of corn earworm and the eggs parasitism were measured from 67 to 101 DAE. Fall armyworm damage was similar between landrace and conventional hybrid, and both higher than those of genetically modified hybrid Bt. Average number of fall armyworm larvae was higher in landrace cultivar. The average of total number of corn earworm larvae was similar on landrace and conventional hybrid, both higher than Bt hybrid. Corn earworm eggs parasitism by Trichogramma pretiosum Riley was recorded in the three evaluated cultivars and similar parasitism percentage was observed between landrace and conventional hybrid, which was higher in Bt maize. Keywords: Spodoptera frugiperda, Helicoverpa zea, Trichogramma pretiosum, Zea mays, pest management.

Spodoptera frugiperda (Lepidoptera: Noctuidae) commonly known as fall armyworm (FAW), is a pest that invaded the sub-tropical and tropical regions of America. In 2016, it was reported for the first time in central Africa and within a year it was reported from many countries of Africa. It then spread in Asia and in 2018 it was reported in India, and now its infestation was seen in Pakistan. Its strong flight, climatic adaptableness and large host range makes it a good colonizing agent as compared to other species of Spodoptera. In potential managing strategies we must know about its primary information such as its biology, host range, habitat and favorable conditions. Identification and life cycle is the most important process in the management of this pest. IPM strategies include physical and cultural control, botanical control, biological control and chemical control. These strategies will help in management of FAW. All these aspects have been reviewed in this article.

Fall Armyworm (Spodoptera frugiperda) is in the state of major threat for Nepal especially in maize although it has more than 80 host to continue its life cycle. After its first incidence in Africa in 2016, it has already spread in more than 100 countries within a short period of time. It was seen in India for the first time in 2018. Due to the open border between Nepal and India, there is high probability of incidence of pest in Nepal. The temperature regime of Nepal is highly suitable for the pest establishment. Now is the time to think about the pest which can cause severe damage to the second most produced cereal crop of Nepal i.e. maize. Management of the pest is possible through many biological, chemical and cultural means. Planting of legumes as a trap crop and ploughing field properly before planting the field can be a best possible cultural method of managing the pest. Natural enemies like Telenomus, Trichogramma chilotraeae for controlling the eggs, Bacillus thuringiensis for larvae and Brachymeria ovata for pupa of Fall Armyworm in Maize and Vegetables. Similarly, Neem extracts are found be larvicidal and the oil extracted from the seeds of long pepper are found to be checking Spermatogenesis of the pest. Chemicals like Methomyl, Cyfluthrin, Methyl parathion are used tocontrol the pest. Use of chemicals at the initiation of the pest spread is discouraged as it can hamper the natural enemy present in the surrounding ecology. However, the use of pesticides can be done below the economic threshold level so that the pest does not develop any resistance towards the chemicals.

Fall armyworm (FAW) was reported for the first time in Africa in 2016. FAW is widely distributed in Ethiopia, causing significant damage to maize. Nine synthetic insecticides belonging to different chemical groups and 11 pesticidal plants (botanicals) were tested for their efficacy against FAW under laboratory, greenhouse, and field conditions. In the laboratory, Radiant, Tracer, Karate, and Ampligo caused over 90% larval mortality 72 h after application. Malathion had moderate activity, causing 51.7% mortality 72 h after application, while Carbaryl was less effective, causing 28% mortality 72 h after application. In the greenhouse experiment, all synthetic insecticides reduced foliar damage to maize compared to the untreated control. Chemical sprays did not affect plant height, stem thickness, or leaf number. The highest fresh weight (471 g) was obtained from plants treated with Radiant. Among the botanicals tested, Azadirachta indica, Schinnus molle, and Phytolacca dodecandra resulted in the highest percentage larval mortality (>95%) 72 h after application. In the field, non-treated control plants showed extensive leaf injury compared to the synthetic insecticide- and botanical-treated plants. The synthetic insecticides and botanicals that showed high efficacy against FAW larvae can be used as components for integrated pest management (IPM) plans for FAW under smallholder farmer conditions in Ethiopia and elsewhere in Africa.

The fall armyworm (FAW) Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) has successfully invaded Africa, where it has significantly impacted maize and sorghum production. Management of FAW in Africa predominantly relies on synthetic insecticides, which are expensive, and negatively impact the environment and beneficial insects. We, therefore, conducted field surveys in Uganda in 2017 and 2019 to identify egg and larval parasitoids of FAW for possible use in integrated pest management (IPM) programs. Parasitoids were identified by their mitochondrial DNA cytochrome c oxidase subunit 1 (mtCOI) gene sequences. We identified 13 parasitoid species belonging to three families of Hymenoptera: Platygastridae, Braconidae and Ichneumonidae, as well as one Dipteran family (Tachinidae). Coccygidium spp. and Chelonus bifoveolatus were the most abundant and widely distributed parasitoids. Overall, parasitism averaged 9.2% and ranged from 3.1% to 50% in 2017, and 0.8% to 33% in 2019. Parasitism by Sturmiopsis parasitica, Diolcogaster sp., and Cotesia flavipes on FAW in maize crops are reported for the first time. Our results suggest high biological diversity of FAW parasitoids, which should be exploited in the IPM of the FAW in Uganda.

This work presents the size-selective sorting of single biological cells using the assembly process known as Templated Assembly by Selective Removal (TASR). We have demonstrated experimentally, for the first time, the selective self assembly and sorting of single SF9 cells (a clonal isolate, derived from Spodoptera frugiperda (Fall Armyworm) IPLB-Sf21-AE cells) into patterned hemispherical sites on rigid assembly templates using TASR. TASR-based size-selective assembly of biological systems represents a potentially valuable tool, with potential for implementation in several biological applications, such as cell sorting for medical research or diagnostics, or isolation of single cells for the study of biological or mechanical behavior.

For Slovenes in the Kingdom of the Serbs, Croats and Slovenes the year 1919 represented the final step to a new political beginning. With the end of the united all-Slovene liberal party organisation and the formation of separate liberal parties, the political party life faced a new era. Similar development was showing also in the Marxist camp. The Catholic camp was united. For the first time, Slovenes from all political camps took part in the state government politics and parliament work. They faced the diminishing of the independence, which was gained in the State of Slovenes, Croats and Serbs, and the mutual fight for its preservation or abolition. This was the beginning of national-political separations in the later Yugoslav state. The year 1919 was characterized also by the establishment of the Slovene university and early occurrences of social discontent. A declaration about the new historical phenomenon – Bolshevism, had to be made. While the region of Prekmurje was integrated to the new state, the questions of the Western border and the situation with Carinthia were not resolved. For the Slovene history, the year 1919 presents a multi-transitional year.
