Integrated Management of the Fall Armyworm on Maize Fall Armyworm FAW, a dangerous transboundary pest native to the Americas, has been spreading rapidly to all sub-regions of Africa since 2016, causing significant damage to C crops. Farmer education and community action are critical elements in the strategy to best manage M FAW populations, using an integrated and ecological pest management approach. Farmer Field School Y (FFS), a holistic farmer education approach used in over 90 countries, will be a key component of the CM response effort. MY CY CMY K This guide seeks to provide guidance on how to conduct FFS on the integrated and sustainable management of the FAW in Africa, with emphasis on maize as FAW’s preferred host plant. It provides information on the biology and ecology of FAW; field studies and exercises for use in season-long Farmer Field Schools; and suggestions on how to build a Integrated management training programme for rural advisory services/extension on FAW and FFS refresher courses of the Fall Armyworm on maize of Master Trainers and facilitators.

Visalakshi1* , P. Kishore Varma1, V. Chandra Sekhar1, M. Bharathalaxmi1, B. L. Manisha2 and S. Upendhar3 Abstract Background: Mycosis on the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), infecting maize was observed in research farm of Regional Agricultural Research Station, Anakapalli from October 2019 to February 2020. Main body: High relative humidity (94.87%), low temperature (24.11 °C), and high rainfall (376.1 mm) received during the month of September 2019 predisposed the larval instars for fungal infection and subsequent high relative humidity and low temperatures sustained the infection till February 2020. An entomopathogenic fungus (EPF) was isolated from the infected larval instars as per standard protocol on Sabouraud’s maltose yeast extract agar and characterized based on morphological and molecular analysis. The fungus was identified as Metarhizium (Nomuraea) rileyi based on ITS sequence homology and the strain was designated as AKP-Nr-1. The pathogenicity of M. rileyi AKP-Nr-1 on S. frugiperda was visualized, using a light and electron microscopy at the host-pathogen interface. Microscopic studies revealed that all the body parts of larval instars were completely overgrown by white mycelial threads of M. rileyi, except the head capsule, thoracic shield, setae, and crotchets. The cadavers of larval instars of S. frugiperda turnedgreenonsporulationand mummified with progress in infection.

  • Fungal Pathogens Occurring on <I>Orthopterida</I> in Thailand
    Persoonia 44, 2020: 140–160 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/persoonia.2020.44.06 Fungal pathogens occurring on Orthopterida in Thailand D. Thanakitpipattana1, K. Tasanathai1, S. Mongkolsamrit1, A. Khonsanit1, S. Lamlertthon2, J.J. Luangsa-ard1 Key words Abstract Two new fungal genera and six species occurring on insects in the orders Orthoptera and Phasmatodea (superorder Orthopterida) were discovered that are distributed across three families in the Hypocreales. Sixty-seven Clavicipitaceae sequences generated in this study were used in a multi-locus phylogenetic study comprising SSU, LSU, TEF, RPB1 Cordycipitaceae and RPB2 together with the nuclear intergenic region (IGR). These new taxa are introduced as Metarhizium grylli­ entomopathogenic fungi dicola, M. phasmatodeae, Neotorrubiella chinghridicola, Ophiocordyceps kobayasii, O. krachonicola and Petchia new taxa siamensis. Petchia siamensis shows resemblance to Cordyceps mantidicola by infecting egg cases (ootheca) of Ophiocordycipitaceae praying mantis (Mantidae) and having obovoid perithecial heads but differs in the size of its perithecia and ascospore taxonomy shape. Two new species in the Metarhizium cluster belonging to the M. anisopliae complex are described that differ from known species with respect to phialide size, conidia and host. Neotorrubiella chinghridicola resembles Tor­ rubiella in the absence of a stipe and can be distinguished by the production of whole ascospores, which are not commonly found in Torrubiella (except in Torrubiella hemipterigena, which produces multiseptate, whole ascospores). Ophiocordyceps krachonicola is pathogenic to mole crickets and shows resemblance to O. nigrella, O. ravenelii and O. barnesii in having darkly pigmented stromata. Ophiocordyceps kobayasii occurs on small crickets, and is the phylogenetic sister species of taxa in the ‘sphecocephala’ clade.

Received: 17 July 2019; Accepted: 31 October 2019; Published: 2 November 2019 Abstract: Fungal entomopathogens are gaining increasing attention as alternatives to chemical control of arthropod pests, and the literature on their use under different conditions and against different species keeps expanding. Our review compiles information regarding the entomopathogenic fungal species Metarhizium flavoviride (Gams and Rozsypal 1956) (Hypocreales: Clavicipitaceae) and gives account of the natural occurrences and target arthropods that can be controlled using M. flavoviride. Taxonomic problems around M. flavoviride species sensu lato are explained. Bioassays, laboratory and field studies examining the effect of fermentation, culture regimes and formulation are compiled along with studies on the effect of the fungus on target and non-target organisms and presenting the effect of management practices on the use of the fungus.

Abstract – Isolates of the entomopathogenic fungus Metharhizium rileyi (Farlow) Samson of Spodoptera litura (Fabricius) origin were studied for efficacy against the host insects. Laboratory bioassays at a concentration of 5,2 × 108 conidia ml−1 indicated that M. rileyi isolates showed mortality (65.5–82.5% mortality in 9 days) in test larvae of Spodoptera litura. It can be inferred from this study that M. rileyi isolate has great potential for use in the control of Spodoptera litura at the recommended dose of 5.2 x 108 causing the mortality around 60-80%. Factors such as virulence and spore viability must also be considered for commercial production of the biological product. Keywords – Entomopathogenic Fungus, Biological Control, Sporulation, Virulence, Insecticides. I. INTRODUCTION The tobacco caterpillar, Spodoptera litura (Fabricius), is one of the most destructive pests of various crops [1].
