Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

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.

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

Update on Pink Bollworm Resistance to Bt Cotton in the Southwest

, 2004
Monitoring of Arizona pink bollworm (PBW), Pectinophora gossypiella, susceptibility to the Bt toxin Cry1Ac has been conducted annually since 1997. PBW were collected from cotton fields located throughout the Southwest in 2002, cultured in the laboratory,

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

Triple Techniques to Relieve Critical-time Stress of Cotton Plants to Maximize Bio-resource Output and Farm Returns

International Journal of Bio-Resource and Stress Management, 2010
Cotton is grown under irrigated as well as fully rain-fed conditions. However, prolonged water stress at boll maturity and fiber development stage often causes yield reduction and produces poor quality fibers.
