Bt agave: why it is time to explore a new biotechnological frontier

Pest Management Science, Volume 82, Issue 9, Page 8053-8063, September 2026.
Drylands cover 41% of Earth, requiring sustainable crops. Agave, drought‐ and heat‐adapted, offers high‐value products with low water needs. Pests limit yield, yet Bacillus thuringiensis (Bt) Cry proteins, successful in other plants, remain unexploited in Agave.

Molecular characterization of Helicoverpa armigera Nucleopolyhedrovirus (HearNPV) on Helicoverpa armigera Hübner larvae (Lepidoptera: Noctuidae)

Jurnal Hama dan Penyakit Tumbuhan Tropika
Nucleopolyhedrovirus (NPV) is a type of biological agent that can be effectively used as a bioinsecticide to control the cob borer caterpillar in corn. Among these viruses, HearNPV (Helicoverpa armigera Nucleopolyhedrovirus) stands out due to its host specificity, environmentally safety, and lack of harm to non-target organisms.

Effect of pretreatment with piperonyl butoxide on pyrethroid efficacy against insecticide-resistant Helicoverpa armigera (Lepidoptera: Noctuidae) and Bemisia tabaci (Sternorrhyncha: Aleyrodidae)

, 2006
Pyrethroid resistance in B-type Bemisia tabaci Gennadius and Australian Helicoverpa armigera Hubner field populations is primarily conferred by esterase isoenzymes which metabolise and sequester pyrethroid insecticides.

Progress in understanding hormonal regulation during the postembryonic development of Helicoverpa armigera

Journal of Integrative Agriculture, 2020
Lepidoptera, with 0.16 million species, is the second largest order of insecta. This order includes silk worms, butterflies, and many agricultural pests. The cotton bollworm, Helicoverpa armigera (Hübner) is one of the pests in Lepidoptera that seriously

Elevated UV‐B alters anti‐herbivore plant defence allocation, while silicon supplementation maintains resistance

Functional Ecology, Volume 40, Issue 9, Page 2982-3000, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The impacts of elevated surface ultraviolet‐B (UV‐B) on ecological processes, such as anti‐herbivore defence in plants, remain poorly understood. Many cereal crops depend on accumulating silicon (Si) in their tissues to resist insect herbivory.
