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.

Applications of nanocarrier‐delivered RNA interference in agricultural biological control (2009–2025)

New Plant Protection, EarlyView.
Despite 17 years of development, the effectiveness of nanocarrier‐delivered RNAi pesticide (NDRP) for agricultural biological control remains limited. The successful development of effective NDRP development requires the coordinated optimization of target gene selection and nanocarrier properties, including RNA dosage, multi‐gene targeting, protection ...

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

Bt Cry2A pesticidal proteins—A case study for the development of future insecticidal proteins?

New Plant Protection, EarlyView.
Abstract This commentary highlights recent advances in engineering Cry2A proteins from Bacillus thuringiensis (Bt) for improved insecticidal activity. Through metagenomic discovery, domain‐swapping, and ancestral sequence reconstruction, key determinants of host specificity have been identified.

Characterization of Cry2Ab2 resistance in Crocidosema sp. (Lepidoptera: Tortricidae): resistance selection, inheritance, cross‐resistance patterns, and fitness costs

Pest Management Science, EarlyView.
This article reports the first characterization of Cry2Ab2 resistance in Crocidosema sp. Resistance appears to be autosomal and incompletely recessive, with a major‐gene contribution and potential involvement of additional genetic factors, and did not confer cross‐resistance to Cry1Ac or Cry1A.105. Abstract BACKGROUND The soybean bud borer, Crocidosema
