Efficacy of cry2AX1 Gene in Transgenic Tomato Plants against Helicoverpa armigera and Spodoptera litura

Madras Agricultural Journal, 2018
Tomato crop is infested by large number of insect pests, causing significant yield loss. Fruit borer (Helicoverpa armigera) feeds on fruits which leads to quality detoriation and economic loss.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

Agricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Pest‐preservation paradox among insects

Conservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

Evidence for a defensive ceiling in the effectiveness of plant silicon defences against an insect herbivore

Ecological Entomology, EarlyView.
Silicon‐mediated resistance in wheat reaches a defensive plateau; accumulating silicon beyond 2mM provides no additional benefit for suppressing insect herbivore relative growth rates. Silicon supplementation significantly increases wheat biomass and effectively ameliorates plant mass losses caused by Helicoverpa armigera herbivory. Lower mandible wear

Comparative Toxicity of Helicoverpa armigera and Helicoverpa zea (Lepidoptera: Noctuidae) to Selected Insecticides

Insects, 2020
Until recently, the Old World bollworm (OWB) Helicoverpa armigera (Hübner) and the corn earworm Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) were geographically isolated.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

Improved impact from the use of beneficial natural enemy species in Australian canola systems: challenges and required tools

Pest Management Science, Volume 82, Issue 11, Page 10540-10550, November 2026.
In canola production systems in Australia, practices for the use of beneficials (arthropod predators and parasitoids) as part of an Integrated Pest Management (IPM) strategy, have not been widely adopted. We outline how canola growers and their advisors can be supported with incremental steps, from passive to active management, to help shift them from ...
