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

Completed Genomic Sequence of Bacillus thuringiensis HER1410 Reveals a Cry-Containing Chromosome, Two Megaplasmids, and an Integrative Plasmidial Prophage

G3: Genes, Genomes, Genetics, 2020
Bacillus thuringiensis is the most used biopesticide in agriculture. Its entomopathogenic capacity stems from the possession of plasmid-borne insecticidal crystal genes (cry), traditionally used as discriminant taxonomic feature for that species. As such,

Inheritance and fitness costs of field‐evolved resistance to Gpp34/Tpp35Ab1 corn by western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)

Pest Management Science, EarlyView.
Field‐evolved resistance to Gpp34/Tpp35Ab1 corn in two western corn rootworm strains was inherited in a non‐recessive manner and was associated with fitness costs. Abstract BACKGROUND The western corn rootworm, Diabrotica virgifera virgifera LeConte, is among the most serious pests of corn in the United States, and an invasive pest in parts of Europe ...

Cloning and analysis sequence of Bacillus thuringiensis ENTOMOCIDUS INA 288

, 2020
B. thuringiensis has been studied worldwide over the past decades, mainly because this gram-positive bacterium produces significant amounts of crystal protein toxic activity against economically important insect larvae. Most strains of B. thuringiensis

Bacillus toyonensis biovar Thuringiensis: an overlooked entomopathogen?

Journal of Bacteriology
Horizontal gene transfer significantly influences prokaryotic genome evolution. Bacillus cereus and Bacillus thuringiensis are nearly identical at the chromosomal level, except for B. thuringiensis producing parasporal crystals.

Strain‐specific monitoring of Bacillus amyloliquefaciens AH2 in strawberry fields using a specific molecular marker

Pest Management Science, EarlyView.
A novel strain‐specific TaqMan quantitative polymerase chain reaction assay targeting the hsdM gene was developed to monitor Bacillus amyloliquefaciens AH2 in strawberries, providing a foundational tool to optimize biocontrol management. Abstract BACKGROUND The biocontrol agent Bacillus amyloliquefaciens AH2 is effective against Botrytis cinerea in ...

Inheritance and stability of Cry2Ab2 resistance in an Ostrinia nubilalis strain originating from Wisconsin, U.S.

Pest Management Science, EarlyView.
Resistance to Cry2Ab2 protein in Ostrinia nubilalis is autosomal, functionally recessive, controlled by a single gene, and remains stable over 17 generations in the absence of Cry2Ab2 selection pressure. Abstract BACKGROUND Transgenic corn expressing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt), including Cry1Ab, Cry1Fa and/or ...

On‐farm comparison of aerial and chemigation application methods for Striacosta albicosta (lepidoptera: Noctuidae) management in corn using pyrethroid and diamide insecticides

Pest Management Science, EarlyView.
Aerial applications deposited more insecticide on tassels than on ear level (36.4% vs. 19.8%). Across both application methods, chlorantraniliprole minimized ear injury, while bifenthrin provided moderate control. Effective management of S. albicosta requires delivering sufficient insecticide concentration to the target site and achieving adequate ...
