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.

Economic injury level for sugarcane caused by the spittlebug Mahanarva fimbriolata (Stål) (Hemiptera:Cercopidae) Nível de dano econômico em cana-de-açúcar causado pela cigarrinha das raízes Mahanarva fimbriolata (Stål) (Hemiptera:Cercopidae)

Scientia Agricola, 2008
The sugarcane spittlebug, Mahanarva fimbriolata (Stål), is currently one of the most important pests of the sugarcane crop in Brazil. In spite of its economic importance, advances in the management of this pest have been limited by the lack of ...

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

Effects of Atmospheric CO2 Levels on the Susceptibility of Maize to Diverse Pathogens

Plant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 has significant implications for crop productivity and food security. Based on studies in C3 plants, elevated CO2 (eCO2) can shape plant‐pathogen interactions, although the outcomes are often variable. The question of how eCO2 influences immunity and disease development in C4 plants, such as the globally important cereal

Emerging insights into silicon-mediated defence systems against insect pests in sugarcane

Discover Plants
Silicon has been recognized as an important beneficial element in cereal and grass crops like sugarcane. Sugarcane, among the world's leading sugar-producing crops, is extremely vulnerable to insect attack with an estimated loss in yield of 20% in cane ...

Disruption of Fatty Acid Desaturase Gene Alters Aphid Resistance and Volatile Emissions in Sorghum

Plant, Cell &Environment, EarlyView.
ABSTRACT Jasmonic acid (JA)‐deficient msd3 sorghum mutants exhibit contrasting resistance phenotypes against sugarcane aphids (SCA; Melanaphis sacchari), which promotes aphid settling at early time points while providing antibiosis‐mediated resistance at later stages. Here we investigated the physiological, hormonal, and metabolic mechanisms underlying

Dry Rot Caused by the Complex Colletotrichum falcatum and Thielaviopsis paradoxa Emerges as a Key Stalk Disorder in Newly Expanded Sugarcane Plantations from Northwestern São Paulo, Brazil

, 2023
Sugarcane dry rot emerged as an important stalk disorder in newly expanded plantations in northwestern São Paulo, Brazil, under the current no-burning fully mechanical harvest policy gradually implemented in the past 20 years. This emergence was probably

We Are Dying to Eat You: Cannibalism and Disease Transmission Under Global Climate Change

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Fall armyworm (Spodoptera frugiperda), a devastating agricultural pest that can be infected by a lethal virus, readily cannibalize conspecifics. The armyworm in the photo has just consumed a smaller conspecific—note the head capsule of the victim in its mandibles. Cannibalistic consumption can impact disease transmission.
