Unraveling the Coevolutionary Arms Race: Insights into the Dynamic Interplay of Plants, Insects and Associated Organisms

Опубликована: Янв. 1, 2024

Insect–plant interactions are complex and dynamic relationships that have evolved over millions of years. Plants developed various adaptations to deter insect herbivores, including physical, chemical, induced defences. In response, insects detoxification mechanisms, behavioural adaptations, physiological overcome these This coevolutionary arms race has shaped the between plants insects, leading a diverse array strategies counter-strategies. Additionally, other associated organisms such as endosymbionts rhizosphere microbes been shown play critical role in interactions. Endosymbionts can alter nutritional quality plant tissue confer resistance environmental stressors, while influence growth nutrient uptake. Understanding insect–plant important implications for protection management. By leveraging relationships, we develop sustainable eco-friendly approaches crop pest

Abstract Background Seaweeds contain a widespread range of fatty acids (FA), and several them have potential bioactivity. FAs are dynamic members all biota, as well being acknowledged for their critical function in initiating phytohormone interactions acting important participants many defense signalling pathways the plant system. The current study looks at defense-eliciting potentials from green seaweed Chaetomorpha antennina (Bory) Kützing impact on polyphagous insect pest Spodoptera litura (Fab).

Utilizing genetic variation in perennial sorghum to improve host plant resistance to aphids

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Апрель 19, 2025

With growing concerns over the sustainability of conventional farming systems, perennial crops offer an environmentally friendly and resilient alternative for long-term agricultural production. Perennial grain provide numerous benefits, such as low input investment, reduced tillage, soil conservation, better carbon sequestration, sustainable yields, enhanced biodiversity support. Sorghum (Sorghum bicolor) is fifth most-grown cereal crop grown food, fuel, food in world. The development sorghum offers a substitute traditional annual by providing environmental, economic, agronomic benefits. Sugarcane aphid (SCA; Melanaphis sacchari), phloem-feeder, considered major threat to Since its first report 2013, it caused $40.95 million losses South Texas alone 2015, accounting about 19% total value production region. In this study, we screened diverse genotypes using no-choice choice assays determine their innate antibiosis antixenosis resistance levels SCAs. Based on reproduction plant damage rating, bioassay classified 43 into four clusters: highly susceptible, moderately resistant, resistant. To further investigate mechanisms, selected two genotypes, X999 > R485 (SCA-resistant) PR376 ~ Tift241 (SCA-susceptible) that showed greatest variation SCA, subsequent experiments. Choice results indicated aphids chose settlement, whereas no significant preference was observed compared control genotype. Electrical penetration graph (EPG) demonstrated feeding SCA-resistant genotype spent significantly less time phloem phase than susceptible plants. identification will be valuable future breeding programs managing economically important pest.

Comparison of resistance to Glyphodes pyloalis Walker (Lepidoptera: Pyralidae) among cultivars of mulberry (Moraceae)

The Canadian Entomologist, Год журнала: 2025, Номер 157

Опубликована: Янв. 1, 2025

Abstract Glyphodes pyloalis Walker (Lepidoptera: Pyralidae) is a destructive monophagous pest of mulberry, Morus Linnaeus (Moraceae), trees. In order to identify mulberry cultivars resistant G. , 12 were examined using field and in vitro testing. Field observations indicated that AlbapC, BombyL, LaeviT, CathaB had less than 10.0% damage, with no observed damage on the cultivar. The life table parameters showed cultivar longest larval pupal duration (23.2 days total), shortest adult period (5.3 days), lowest rates both pupation (55.0%) emergence (69.7%), highest mortality (61.7%), average weight pupae (30.4 mg), daily oviposition (5.0 eggs/female/day). performance revealed density. Correlation analyses confirmed significant correlations exist between all for performance. Leaf characterisation selected significantly higher values leaf wax, trichome density, soluble glucose, protein contents compared MultiQ. This study would be valuable reference evaluating pest-resistant establishing theoretical foundation managing .
