Lippia umbellata Cav.: Chemical Composition, Insecticidal, and Antimicrobial Activities

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Hexane extracts of Lippia umbellata leaves and flowers contain lupenone, α‐amyrin, and hentriacontane. They exhibit insecticidal activity against Drosophila melanogaster and inhibit AChE in vitro and in silico. Furthermore, the extracts can inhibit the growth of medically important bacteria and yeasts, including multidrug‐resistant strains.

Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

Pest Management Science, Volume 82, Issue 8, Page 7746-7757, August 2026.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

Pest Management Science, Volume 82, Issue 8, Page 7903-7914, August 2026.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

Role of Certain Elicitors on the Chemical Induction of Resistance in Tomato against the Leaf Caterpillar Spodoptera litura Fab.

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2008
Mill. The four presumptive defenses manipulated were protinase inhibitors, polyphenol oxidase, peroxidase and lipoxygenase. The elicitors used were jasmonic acid (JA), salicylic acid (SA) and PGPR Pseudomonas aeruginosa.

Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 887-895, August 2026.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Lethal and Sublethal Effects of Three Microbial Biocontrol Agents on Spodoptera litura and Its Natural Predator Rhynocoris kumarii

Insects, 2018
Entomopathogenic microbes such as Spodoptera litura nucleopolyhedrovirus (SpltNPV), Metarhizium anisopliae, and Pseudomonas fluorescens are biological agents used for the control of multiple arthropod pests.

Development of PCR, LAMP and HRM‐Based Molecular Species Diagnostic Tools for Identifying Four Agricultural Pests in the Genus Helicoverpa (Lepidoptera: Noctuidae)

Journal of Applied Entomology, Volume 150, Issue 7, Page 900-913, August 2026.
ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.

Molecular identification and characterization of the Orco orthologue of Spodoptera litura

Insect Science, 2012
Abstract  A highly conserved and broadly expressed receptor protein Orco (olfactory coreceptor) is crucial for insect olfaction, and an orthologue of Orco has been identified in several insect species. Here we report the identification and characterization of Orco from Spodoptera litura.

The multifaceted regulatory network of microRNA396: Orchestrating plant plasticity through coordinating development and various stresses

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 3073-3085, August 2026.
This review examines the character and function of the microRNA miR396, which helps plants balance growth, reproduction, regeneration, and survival under various stresses, highlighting recent progress and evidence that this pathway shapes crop yield, pest and disease resistance, and tissue regeneration, making it a promising target for precision crop ...
