ABSTRACT Fertilisers are used in agriculture to promote crop productivity. There many nutrient sources fertilisers, and different cause variation plant defence pest tolerance. Assessing how pests respond types of fertilisers is key develop integrated management programs. Here, we assessed two applied quinoa ( Chenopodium Willd.) affected cowpea aphid Aphis craccivora Koch . ) Lygus spp. survival reproduction. Quinoa a newly introduced the USA, fertiliser regimes using organic or synthetic...
Soil bacteria that associate with plant roots promote host vigor. Legume plants form mutualisms rhizobial bacteria, and legumes grown rhizobia have more nutrients defenses than those without rhizobia. However, few studies tested how stressors such as herbivores affect soil rhizobia, the mechanisms mediating these interactions. Here we reciprocal interactions between a chewing herbivore, Sitona lineatus (pea leaf weevil), Pisum sativum (pea) or (Rhizobium leguminosarum biovar. viciae),...
Soil rhizobia promote nitrogen fixation in legume hosts, maximizing their tolerance to different biotic stressors, plant biomass, crop growth, and yield. While the presence of soil is considered beneficial for plants, few studies have assessed whether variation abundance affects legumes stressors. To address this, we effects variable inoculum concentrations on interactions between a host (Pisum sativum), vector insect (Acyrthosiphon pisum), virus (Pea enation mosaic virus, PEMV). We showed...
In agroecosystems, plants frequently confront multiple biotic stressors, including herbivores and pathogens. The nature of these interactions plays a crucial role in mediating the activation plant defense mechanisms. However, induction chemical defenses has been more well studied than physical defenses. Here, we assessed responses pea (Pisum sativum) after exposure to three stressors: vector herbivore (pea aphid, Acrythosiphon pisum), non-vector leaf weevil, Sitona lineatus), virus (Pea...
Many lady beetles expel an autogenously produced alkaloid-rich 'reflex blood' as antipredator defense. We conducted experiment to determine whether there was a measurable fitness cost associated with the daily induction of this defensive behavior, and costs differed between native (Coccinella novemnotata Herbst (Coleoptera: Coccinellidae)) invasive species septempunctata L. Coccinellidae) Harmonia axyridis (Pallas) Coccinellidae)). Newly mated females were provided restricted or unrestricted...
Abstract Arthropods that vector plant pathogens often interact with predators within food webs. Predators affect vectors by eating them (consumptive effects) and inducing antipredator behaviors (non-consumptive effects), these interactions may transmission of vector-borne pathogens. However, it has proven difficult to experimentally tease apart the effects on fitness behavior as they are correlated. We addressed this problem assessing how both aphids an aphid-borne pathogen were affected...
Abstract Soil bacteria that form mutualisms with plants, such as rhizobia, affects susceptibility of plants to herbivores and pathogens. rhizobia also promote nitrogen fixation, which mediates host nutrient levels defenses. However, whether aboveground affect the function soil remains poorly understood. We assessed reciprocal interactions between Sitona lineatus , a chewing herbivore, pea ( Pisum sativum ) grown or without Rhizobium leguminosarum biovar viciae) . examined underlying...
