Oviposition behavior of Helicoverpa armigera in soybean [PDF]

Arquivos do Instituto Biológico, 2020
ABSTRACT The objective of this study was to evaluate the oviposition behavior of Helicoverpa armigera confined in different adult pair density and growth stages of soybean plants, and the resistance of soybean genotypes to H. armigera in the category nonpreference for oviposition. The oviposition behavior of H. armigera was assessed using one, two, and

Gene-flow between populations of cotton bollworm Helicoverpa armigera (Lepidoptera: Noctuidae) is highly variable between years

, 2005
Both large and small scale migrations of Helicoverpa armigera Hübner in Australia were investigated using AMOVA analysis and genetic assignment tests. Five microsatellite loci were screened across 3142 individuals from 16 localities in eight major cotton

Immune responses of Helicoverpa armigera to different kinds of pathogens [PDF]

BMC Immunology, 2010
Insects react against pathogens through innate immunity. The cotton bollworm Helicoverpa armigera (H. armigera) is an important defoliator and an extremely destructive pest insect of many crops. The elucidation of the mechanism of the immune response of H.

Partial Functional Rescue of Helicoverpa armigera Single Nucleocapsid Nucleopolyhedrovirus Infectivity by Replacement of F Protein with GP64 from Autographa californica Multicapsid Nucleopolyhedrovirus

, 2010
Two distinct envelope fusion proteins (EFPs) (GP64 and F) have been identified in members of the Baculoviridae family of viruses. F proteins are found in group II nucleopolyhedroviruses (NPVs) of alphabaculoviruses and in beta- and deltabaculoviruses ...

Genomic innovations, transcriptional plasticity and gene loss underlying the evolution and divergence of two highly polyphagous and invasive Helicoverpa pest species

BMC Biology, 2017
Background Helicoverpa armigera and Helicoverpa zea are major caterpillar pests of Old and New World agriculture, respectively. Both, particularly H. armigera, are extremely polyphagous, and H. armigera has developed resistance to many insecticides. Here

PATHOGENICITY OF HELICOVERPA ARMIGERA NUCLEOPOLYHEDRO VIRUS (HEARNPV) AND LECANICILLIUM SP. AGAINST HELICOVERPA ARMIGERA

Journal of Biopesticides, 2018
ABSTRACT Helicoverpa armigera (Hubner) is an important pest of corn crops. Lecanicillium sp. and Helicoverpa armigera Nucleopolyhedro virus (HearNPV) are biological control agents that are safe for the environment. This study observed pathogenicity of HearNPV and Lecanicillium sp. against eggs and larvae H. armigera.
