Evolution of an insect immune barrier through horizontal gene transfer mediated by a parasitic wasp. [PDF]

open access: yes, 2019
Genome sequencing data have recently demonstrated that eukaryote evolution has been remarkably influenced by the acquisition of a large number of genes by horizontal gene transfer (HGT) across different kingdoms.

Transmisssion Dynamics of Enterococcus spp. Throughout the Heliconius erato phyllis (Lepidoptera; Nymphalidae) Life Cycle

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Enterococcus spp. dominate the gut microbiota of Heliconius erato phyllis, transmitted horizontally via host plants (Passiflora suberosa) and persisting through development. Multidrug‐resistant strains were found in larvae and plants, suggesting environmental reservoirs of antimicrobial resistance. This study reveals key microbial transmission dynamics

Characterization of an Egyptian Spodoptera littoralis nucleopolyhedrovirus and a possible use of a highly conserved region from polyhedrin gene for nucleopolyhedrovirus detection

open access: yesVirology Journal, 2008
An Egyptian isolate of Spodoptera littoralis nucleopolyhedrovirus (SpliNPV) was tested for its potential as biocontrol agent in comparison to Autographa californica multiple nucleopolyhedrovirus (AcMNPV).

Species-specific responses of herbivores to within-plant and environmentally mediated between-plant variability in plant chemistry [PDF]

open access: yes, 2018
Allocation of resources to growth and defense against herbivores crucially affects plant competitiveness and survival, resulting in a specific distribution of assimilates and defense compounds within plant individuals.

Arbuscular Mycorrhizal Fungi Mitigate Drought‐Enhanced Herbivore Performance in Maize

open access: yesPlant, Cell &Environment, Volume 49, Issue 4, Page 2080-2094, April 2026.
ABSTRACT Drought events are becoming increasingly frequent and intense, posing major challenges to crop productivity. Beyond direct water stress, drought can indirectly affect plants by enhancing herbivore performance. While arbuscular mycorrhizal fungi (AMF) have been proposed to alleviate drought stress and to enhance plant resistance to herbivory ...

Biochemical characterization of spiromesifen and spirotetramat as lipid synthesis inhibitors on cotton leaf worm, Spodoptera littoralis

open access: yesBulletin of the National Research Centre, 2019
Background Two lipid synthesis inhibitors compounds (spiromesifen SPM and spirotetramat SPT) were used against the second instar larvae of cotton leaf worm, Spodoptera littoralis under laboratory condition. Toxicity of both compounds was tested.
