Genomic organization of Helicoverpa armigera single-nucleocapsid nucleopolyhedrovirus

Archives of Virology, 2000
The genome organization of the Helicoverpa armigera single-nucleocapsid nucleopolyhedrovirus (HearNPV) was investigated and compared to that of other baculoviruses. A detailed physical map was constructed for the restriction enzymes BamHI, BglII, EcoRI, HindIII, KpnI, PstI, SacI and XhoI.

Characterization of a New Insecticidal Anthraquinone Derivative from an Endophyte of Acremonium vitellinum against Helicoverpa armigera.

Journal of Agricultural and Food Chemistry, 2020
Endophytic fungi have proven to be prolific producers of bioactive secondary metabolites with agricultural applications. In this study, bioassay-guided isolation of the endophytic fungus Acremonium vitellinum yielded four anthraquinone derivatives ...

Resistance Mechanisms of Helicoverpa armigera

2016
The cotton bollworm, Helicoverpa armigera, is one of the major agricultural pest species in the Old World and recently also of the New World. This noctuid moth species is highly polyphagous and possesses a huge geographical distribution and the ability to quickly evolve resistance to insecticides from different chemical classes.

CRISPR-mediated gene knockout reveals nicotinic acetylcholine receptor (nAChR) subunit α6 as a target of spinosyns in Helicoverpa armigera.

Pest Management Science, 2020
BACKGROUND The spinosyn insecticides (spinosad and spinetoram) have been intensively used to control a wide range of agricultural pests. However, resistance to spinosyns has been evolved in several agricultural pests.

Population Dynamics of Helicoverpa armigera on Soybean

Indian Journal of Entomology, 2022
This study on the population dynamites of pod borer Helicoverpa armigera (Hubn.) on soybean revealed that it appeared from 29th Standard meteorological week (SMW) (0.40± 0.10 three leaves/ plant). It increased and reached its peak level of 2.67± 0.17/ 3 leaves/ plant during 33rd SMW.

The Specificity of Helicoverpa armigera Stunt Virus Infectivity

Journal of Invertebrate Pathology, 1999
Helicoverpa armigera stunt virus (HaSV) is a member of the Tetraviridae family of RNA viruses whose replication and expression strategies are not well understood due to the absence of an in vitro cell culture system. We set out to find such a system for HaSV by screening an array of 13 insect and 1 mammalian cell culture lines with both virus particle ...

Down-regulation of lysosomal protein ABCB6 increases gossypol susceptibility in Helicoverpa armigera.

Insect Biochemistry and Molecular Biology, 2020
Cotton bollworm (Helicoverpa armigera) is the major insect herbivore of cotton plants. As its larvae feed and grow on cotton, H. armigera can likely tolerate gossypol, the main defense metabolite produced by cotton plants, through detoxification and ...

Gene expression patterns of Helicoverpa armigera gut proteases

Insect Biochemistry and Molecular Biology, 2005
Relative quantification of reported gut proteinase cDNAs from Helicoverpa armigera larvae fed on various host plants (cotton, chickpea, pigeonpea, tomato and okra), non-host plant PIs (winged bean, bitter gourd, ground nut, and capsicum) and during larval development has been carried out using semi-quantitative RT-PCR.

Baseline susceptibility and frequency of resistance to diamide insecticides in Helicoverpa armigera (Lepidoptera: Noctuidae) populations in Brazil

, 2020
Diamide insecticides have been widely used to manage Helicoverpa armigera (Hubner) since the official detection of this pest in Brazil in 2013. Characterizing the baseline susceptibility of H.
