The highly polyphagous Old World cotton bollworm Helicoverpa armigera is a quarantine agricultural pest for the American continents. Historically H. thought to have colonised continents around 1.5 2 million years ago, leading current zea populations on relatively recent species divergence history evident in mating compatibility between and under laboratory conditions. Despite periodic interceptions of into North America, this not believed successfully established significant either...
Helicoverpa armigera and H. zea are amongst the most significant polyphagous pest lepidopteran species in Old New Worlds respectively. Separation of is difficult usually only achieved through morphological differences genitalia. They capable interbreeding to produce fertile offspring. The single status has been doubted, due its wide distribution plant host range across World. This study explores global genetic diversity evolutionary relationship H zea.We obtained partial (511 bp)...
Two new species of genus Bactrocera Macquart, namely B. (Sinodacus) brevipunctata David and Hancock, sp. nov. (Bactrocera) furcata nov., are described from India. (B.) aethriobasis Hardy, rubigina Wang & Zhao, syzygii Tsuruta White tuberculata (Bezzi) recorded for the first time Updated keys to twelve subgenera Indian also provided.
Abstract The Old World bollworm Helicoverpa armigera is now established in Brazil but efforts to identify incursion origin(s) and pathway(s) have met with limited success due the patchiness of available data. Using international agricultural/horticultural commodity trade data mitochondrial DNA (mtDNA) cytochrome oxidase I (COI) b (Cyt ) gene markers, we inferred origins pathways into Brazil. We detected 20 mtDNA haplotypes from six Brazilian states, eight which were new our 97 global COI-Cyt...
Developing lepidopteran microsatellite DNA markers can be problematical, as often exhibit multiple banding patterns and high frequencies of non-amplifying "null" alleles. Previous studies identified sequences flanking simple sequence repeat (SSR) units that are shared among many species grouped into microsatellite-associated families. These families thought to associated with unequal crossing-over during recombination or transposable elements (TEs).We full-length non-LTR retrotransposable...
Abstract The four significant pest species in the Helicoverpa genus ( H. armigera, assulta , punctigera and zea ) are morphologically similar can only be reliably distinguished through dissection of adult genitalia. Two partial regions mitochondrial DNA (mtDNA), cytochrome oxidase subunit I (COI) b (Cyt genes were amplified by PCR digested with restriction endonucleases. patterns, generated endonucleases BstZ 17I Hph I, demonstrated reliable differentiation species. This technique is fast,...
Helicoverpa armigera is an important pest of cotton and other agricultural crops in the Old World. Its wide host range, high mobility fecundity, ability to adapt develop resistance against all common groups insecticides used for its management have exacerbated status. An understanding population genetic structure H. under Indian conditions will help ascertain gene flow patterns across different zones. This study inferred using five Exon-Primed Intron-Crossing (EPIC)-PCR markers. Nested...
Abstract Background The pink bollworm ( Pectinophora gossypiella , PBW) is a major cotton pest, causing economic losses by damaging seeds and fiber. Cotton growers typically use systemic broad-spectrum insecticides for its management, which pose risks to human health the environment. Consequently, there need eco-friendly alternatives. This study evaluates bio-efficacy of entomopathogenic fungus Metarhizium anisopliae strain TMBMA1 against assesses compatibility with insecticides....
Lethal and sub lethal effects of fresh old residues azadirachtin, spinosad, Bacillus thuringiensis var. kurstaki (Bt k), deltamethrin, were evaluated at their recommended field doses against adult immature stages Trichogramma brassicae under in vitro conditions. The experiments carried out the Entomology section Division Crop Protection, ICAR Research Complex for NEH region, Umiam, Meghalaya, 2012–2013. different pesticides determined by bioassays using residual film method, diet...
The behavior of most destructive pest cabbage, Pieris brassicae and that its potential parasitoid, Hyposoter ebeninus, were studied under the influence 4 common Brassica host plantspecies, broccoli, cauliflower knol-kohl. These plant species found to have considerable on egg distribution leaf surface preference for oviposition pupation. number masses was highest knol-khol; however, eggs per mass cabbage. Similarly, larval incidence also cabbage throughout season, indicating is preferred...
Abstract Applying microsatellite DNA markers in population genetic studies of the pest moth Helicoverpa armigera is subject to numerous technical problems, such as high frequency null alleles, occurrence size homoplasy, presence multiple copies flanking sequence genome and lack PCR amplification robustness between populations. To overcome these difficulties, we developed exon-primed intron-crossing (EPIC) nuclear for H. based on ribosomal protein (Rp) Dopa Decarboxylase (DDC) genes sequenced...
Ladybird beetles are generally considered as agriculturally beneficial insects, but the ladybird in coleopteran subfamily Epilachninae phytophagous and major plant feeding pest species which causes severe economic losses to cucurbitaceous solanaceous crops. Henosepilachna pusillanima (Mulsant) is one of important beetle. In this report, we sequenced characterized complete mitochondrial genome H. pusillanima. For sequencing genome, used Ion Torrent platform. The circular was determined be...
North East (NE) India, commonly known as the 'land of seven sisters', is a territory diverse ethnic groups, tribes and culture. Shifting cultivation, locally 'jhum' or 'jhumming', way life for many these since time immemorial. The percentage utilization cultivable area in this region (62.04) less than national average (73.05).
Insect infestation can adversely affect tomato (Solanum lycopersicum L.; Solanaceae) development and yield. Fruit flies (Diptera: Tephritidae) are a serious pest of tomato, spreading to areas where they were not previously found. This study was undertaken determine if tephritid fruit present, which species most abundant, how cultivars responded, what amount damage occurred in the Eastern Himalayas India during May 2014 2015. Mature ripe (n = 20) per cultivar picked at random from 12 weekly...
