The invasion of the Western Hemisphere native fall armyworm (Spodoptera frugiperda; J. E. Smith) (Lepidoptera: Noctuidae) into Eastern has been notable for rapidity and geographical breadth new detections. In year following first discovery in western sub-Saharan Africa 2016, infestations have documented most maize growing regions now expanded beyond with populations recently reported India. These observations could indicate a remarkable capacity rapid establishment long-distance...
The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a phloem-feeding, economically important pest of crops worldwide. In addition to direct damage, it also vectors number plant viruses belonging the family Geminiviridae. Its populations differ biologically with respect insecticide resistance, virus transmission and host range. Therefore, understanding genetic variation among for management. We sequenced 850 bp mitochondrial COI (mtCOI) gene from B. surveyed across India....
The fall army worm (FAW) Spodoptera frugiperda (J.E. Smith) is an invasive pest native to Americas, and it has recently been observed India. mtCOI based analysis of the populations FAW from Americas showed prevalence two strains viz. “R” (Rice) “C” (Corn). Recent studies on Africa revealed predominance strain that feed primarily maize. To understand molecular diversity in India, were made collected maize, sweet corn, sorghum six states India (Karnataka, Tamil Nadu, Andhra Pradesh, Telangana,...
Abstract The fall armyworm (FAW; S podoptera frugiperda ) is one of the major agricultural pest insects. FAW native to Americas, and its invasion was first reported in West Africa 2016. Then it quickly spread through Africa, Asia, Oceania, becoming main threats corn production. We analyzed whole genome sequences 177 individuals from 12 locations on four continents infer evolutionary processes invasion. Principal component analysis TPI gene shows that invasive populations originated strain....
ABSTRACT The Oriental fruit fly, Bactrocera dorsalis ( B. ) is a highly invasive, widely distributed notorious pest restricting global trade immensely. There are several approaches to managing this pest, still require newer approaches. In regard, recently novel approach called precision‐guided sterile insect technique (pgSIT) gaining momentum in inducing both female sex elimination or conversion and male sterility at one go. Developing species‐specific pgSIT system requires validation of...
Abstract A quick and developmental-stage non-limiting method of the identification vectors tospoviruses, such as Thrips tabaci T. palmi , is important in study vector transmission, insecticide resistance, biological control, etc. Morphological these thrips often a stumbling block absence specialist limited by polymorphism, sex, stage development, Molecular identification, on other hand, not hampered above factors can easily be followed non-specialist with little training. The mitochondrial...
Abstract Rapid, precise and timely identification of invasive pest insects such as aphids is important a challenge worldwide due to their complex life cycles, parthenogenetic reproduction, sex colour morphs. In this respect, DNA barcoding employing 658 bp fragment 5′ region the mitochondrial cytochrome oxidase I (CO-I) gene an effective tool in addressing above. present study, we employed CO-I for discriminating 142 individuals representing 32 species from India. Sequence analyses revealed...
Fruit flies that belong to the genus Bactrocera (Diptera: Tephritidae) are major invasive pests of agricultural crops in Asia and Australia. Increased transboundary movement produce has resulted chance introduction many species include mainly as immature stages. Therefore quick accurate diagnosis is important at port entry, where morphological identification a limited role, it requires presence adult specimens availability specialist. Unfortunately when only stages present, lacunae their...
Accurate and timely identification of invasive insect pests underpins most biological endeavors ranging from biodiversity estimation to pest management. In this regard, thrips, an is important challenging due their complex life cycles, parthenogenetic mode reproduction, sex color morphs. the recent years, DNA barcoding employing 5′ region mitochondrial Cytochrome Oxidase I (CO-I) gene has become a popular tool for species identification. study, we employed CO-I sequences discriminating 151...
Abstract The Oriental fruit fly, Bactrocera dorsalis (Hendel), is a highly invasive pest of quarantine importance affecting the global trade. In managing B. , methods like cultural, biological, chemical, sterile insect technique (SIT), and semiochemical‐mediated attract‐and‐kill are in use with varying success. SIT approach method choice for chemical‐free, long‐term suppression followed many countries across globe. nonspecific mutations caused by irradiation affect overall fitness flies,...
Insects have a rich diversity of RNA viruses that can either cause acute infections or persist in host populations without visible symptoms. The melon fly, Zeugodacus cucurbitae (Tephritidae) causes substantial economic losses through infestation diverse cucurbit and other crops. Of Indomalayan origin, it is now established many tropical regions the world. virome Z. largely unknown across large parts its distribution, including Indian subcontinent. We analysed three transcriptomes each one...
Rapid, accurate, and timely identification of insects as a group is important challenging worldwide, they outnumber all other animals in number diversity. DNA barcoding method for the species wide range animal taxa, which uses 5′ region mitochondrial cytochrome c oxidase-I (CO-I). Yet another easy, economical discrimination by developing species-specific markers, produce specific amplicon question. The handy because it not limited life stages, sex, polymorphism, factors. Herein, we measured...
Nearly 6000 species of thrips have been described and only 12 are reported to be vectors tospoviruses (Bunyaviridae) globally In this regard, Thrips palmi Scirtothrips dorsalis two important Watermelon Bud Necrosis Virus (WBNV) Peanut Yellow Spot (PYSV) watermelon groundnut respectively in India. Accurate timely identification the early developmental stages is for understanding epidemiology tospoviruses, their management also quarantine. Morphological often has a stumbling block absence...
Aphids (Hemiptera: Aphidoidea: Aphididae) have distinctive features and significant variability in interesting biological traits. Aphididae comprises c. 5000 species distributed worldwide with a rapid diversification rate, which makes reliable phylogenetic reconstruction difficult as framework for evolutionary inference. Despite several studies, the phylogenies of various subfamilies are not yet resolved, their positions still debated. Our study, based on two mitochondrial markers (COI COII)...
