Effect of Manual Topping on Insect Pest Incidence and Cotton Yield

Crop Protection
Bollworms and sap-sucking insect pests are a significant constraint to cotton production in Africa. Manual topping of cotton plants, which consists of cutting off the top of the plant, i.e. the terminal bud of the main stem, is a promising alternative to chemical control by removing resources for certain pests or inducing plant defences. In this study,

Ozone‐driven degradation of sex pheromone in Plutella xylostella: Implications for reproductive communication and mating success

Insect Science, EarlyView.
In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Guarding the cotton fields by refining the resilience against sucking pests: use of cutting-edge breeding and other techniques

Journal of Cotton Research
In addition to the negative consequences of climate change, sucking pest complexes severely limited cotton yields in the recent past. Although the damage caused by bollworms was much reduced by utilizing Bt cotton, the emergence of sucking pests (such as

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

Genotyping by sequencing reveals a chromosome A04 QTL governing whitefly resistance in upland cotton

Scientific Reports
Cotton plants utilize physical defenses such as trichomes and leaf characteristics to deter insect pests and environmental stressors, safeguarding their growth and productivity. Cotton insect pests such as whiteflies, aphids, jassids and boll weevils not
