Prey Range and Voracity of Main Insect Natural Enemies of Pests in Corsican Clementine Orchards

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
To assess the biocontrol potential on the main arthropod pests of clementine orchards in Corsica, laboratory experiments were carried out using five potential predators. Their prey range and voracity were tested on three pest species. Then, a global predation rate index was calculated at the scale of the entire community of insect predators.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Inducible tomato defences persist in detached leaves, despite differential plant variety and gene‐dependent expression

open access: yesEcological Entomology, EarlyView.
Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.

Field Attraction of Natural Enemies to Methyl Salicylate Differs Between Annual and Perennial Cropping Systems

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow

In vitro techniques in Solanum lycopersicum, Solanum tuberosum, and Solanum × muricatum anthers

open access: yes
In vitro techniques for Solanum transcendental crops were developed, including propagation from tomato seed, micropropagation of potato by tuber sprouts, and sweet pepino anther culture. At all stages of tomato, and potato a completely randomized design (CRD) with or without factorial arrangement was used; and culture media ...

Salt glands in exo‐recretohalophytes: Development, physiological functions, and prospects for improving crop salt tolerance

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

Antimicrobial activity of fruits of Solanum nigrum and Solanum xanthocarpum.

open access: yesActa poloniae pharmaceutica, 2014
Current study was conducted to investigate antimicrobial activity of fruit extracts of two Solanaceous plants (Solanum nigrum and Solanum xanthocarpum) found in Pakistan. Petroleum ether, chloroform, dichloromethane, ethyl acetate, acetone, methanol and water were utilized for extraction.

The multidimensional regulation roles and mechanisms of calcium in fruit quality

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...
