Effect of sequence control sprays on cotton bollworms and side effect on some sucking pests and their associated predators in cotton fields.

, 2010
Field evaluation of sequence control sprays were carried out at AbouHamad district, Sharkia Governorate, Egypt in the two successive cotton growing seasons 2008 and 2009 against cotton bollworms, Pectinophora gossypiella (Sound.), Earias insulana (Boisd.)

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

Development of bollworms, Helicoverpa zea, on two commercial Bollgard® cultivars that differ in overall Cry1Ac levels

Journal of Insect Science, 2004
Research was conducted to quantify the development of the corn earworm (= bollworm), Helicoverpa zea (Boddie), on two different transgenic cotton cultivars (DP 50B and NuCOTN 33B) that contained different levels of the Cry1Ac endotoxin from the soil ...

Bacteriophage P22 Virus‐Like Particles as Nanoscale Protein Scaffolds for Plant Synthetic Biology

Plant Biotechnology Journal, EarlyView.
ABSTRACT Advancing the utility of plant synthetic biology requires the continued development of protein engineering tools. Self‐assembling protein compartments, such as virus‐like particles (VLPs), provide versatile scaffolds for synthetic biology. However, few plant‐expressed VLPs have demonstrated broad amenability to protein engineering, restricting

Bollworm (Lepidoptera: noctuidae) ecology on genetically engineered Bollgard and Bollgard II cottons [PDF]

, 2002
The ecology of bollworms, Helicoverpa zea (Boddie), on Bollgard and Bollgard II cottons, Gossypium hirsutum L., was studied in field and laboratory experiments. Neonate bollworm larvae were placed on selected components of cotton squares and flowers from

Feminist Temporalities of Agrarian‐Climate Crises: Synchronisation and the Afterlives of Speculation in India

Antipode, Volume 58, Issue 6, November 2026.
ABSTRACT This paper brings a feminist temporal perspective to understandings of agrarian‐climate crises in monsoon‐dependent regions of India, examining how time operates as a site of material struggle and social differentiation. Drawing on ethnographic research in Vidarbha, it explores how farmers synchronise diverse temporalities to navigate ...

In-depth analysis of Bt cotton adoption: farmers' opinions, genetic landscape, and varied perspectives—a case study from Pakistan

Journal of Cotton Research
Background Bt technology has played significant role in controlling bollworms and increasing cotton yield in earlier days of its introduction, a subsequent decline in yield became apparent over time.

Impact of conventional insecticides on two bollworms and their indirect effects on the ectoparasitoid, Bracon brevicornis (Wesmael) (Hymenoptera: Braconidae)

Bulletin of the National Research Centre, 2019
Background Cotton bollworms such as Pectinophora gossypiella and Earias insulana are serious pests which destroy the cotton plant, and Bracon brevicornis is a parasitoid which attacked the larvae of bollworms.

Tolerance to Simulated Pod‐Borer Herbivory Among Several Genotypes of Extra Short‐Duration Pigeonpea (Cajanus cajan)

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Pigeonpea is a major global legume crop that provides nutrition and income for some of the world's poorest people. Global pigeonpea yields are constrained due to damage from flower‐ and pod‐feeding lepidopteran pests, particularly Helicoverpa armigera.
