Evaluation of Agave angustifolia as a Sustainable Alternative to Synthetic Pesticides: Phytochemical Composition and Multi‐Trophic Bioactivity

Flavour and Fragrance Journal, EarlyView.
The pesticidal potential of Agave angustifolia by assessing its anti‐nematic, antimicrobial, and insecticidal activities, alongside phytochemical profiling. ABSTRACT Plant diseases caused by fungi, bacteria, nematodes, and viruses contribute significantly to annual crop losses and economic hardship. Reliance on chemical pesticides, over a thousand used

Evaluation of Acephate Metabolites Generated by Zebrafish (Danio rerio) Using LC–HRMS and Metabolomics Approach

Journal of Applied Toxicology, EarlyView.
ABSTRACT Acephate is an organophosphate insecticide widely used. This pesticide can be metabolized into methamidophos, a molecule highly toxic. Both have demonstrated the ability to promote serious toxic effects on nontarget organisms and have been identified in surface waters around the world. Therefore, it is important to understand their behavior in

Identification of Conditions for Successful Aphid Control by Ladybirds in Greenhouses

Insects, 2017
As part of my research on the mass production and augmentative release of ladybirds, I reviewed the primary research literature to test the prediction that ladybirds are effective aphid predators in greenhouses. Aphid population reduction exceeded 50% in

Calcium signaling in plant defense

New Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

Does This Look Infected? Hidden Host Plant Infection by the Pathogen Botrytis cinerea Alters Interactions between Plants, Aphids and Their Natural Enemies in the Field

Insects
Few studies have considered whether hidden (asymptomatic) plant pathogen infection alters ecological interactions at the higher trophic levels, even though such infection still affects plant physiology. We explored this question in two field experiments,

Unmanned aircraft system-derived crop height and normalized difference vegetation index metrics for sorghum yield and aphid stress assessment

, 2017
. A small, fixed-wing unmanned aircraft system (UAS) was used to survey a replicated small plot field experiment designed to estimate sorghum damage caused by an invasive aphid.

Comparative transcriptomics and proteomics of three different aphid species identifies core and diverse effector sets

BMC Genomics, 2016
Aphids are phloem-feeding insects that cause significant economic losses to agriculture worldwide. While feeding and probing these insects deliver molecules, called effectors, inside their host to enable infestation.

“Tremble, pests”: Insect natural enemy‐induced changes in pests before attack and their implications for biological control

New Plant Protection, EarlyView.
Abstract Insect natural enemies, encompassing predators and parasitoids, serve as vital regulators of pest populations and architects of ecosystem balance. Most studies on natural enemies have focused on understanding the mechanisms by which these insects eliminate pests after an attack.

Intercropping Broccoli‐Basil Reduces Aphid Growth: Spatio‐Temporal Modelling Across Scales and Lab Experiments

Journal of Sustainable Agriculture and Environment
Shifting from conventional to sustainable agriculture demands well‐designed experiments and robust analytical models to evaluate agroecological system performance and resilience. We modelled aphid population dynamics in broccoli monocultures and broccoli‐
