Synergistic Effect of Biopesticides against Spodoptera frugiperda and Spodoptera littoralis [PDF]

, 2023
The present work was performed to study the synergistic effect of this new natural formulation on the biological aspects of the 2nd and 4th instar larvae of Spodoptera littoralis and Spodoptera frugiperda.

Route‐Dependent Toxicity and Ecological Selectivity of Melaleuca alternifolia Essential Oil in Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae)

Environmental Toxicology, EarlyView.
ABSTRACT The intensification of agricultural practices has led to an increase in the use of insecticides, raising concerns about the exposure of non‐target organisms, particularly pollinators. In this context, plant‐derived essential oils have been proposed as environmentally friendlier alternatives due to their low persistence; however, their ...

INSECTICIDAL POTENCY OF NATIVE ENTOMOPATHOGENIC FUNGI ISOLATES AGAINST THE Galleria mellonella (LEPIDOPTERA: PYRALIDAE) AND Spodoptera littoralis (LEPIDOPTERA: NOCTUIDAE) Larvae. [PDF]

Journal of Plant Protection and Pathology, 2015
The entomopathogenic fungi (EPF) have received considerable attention for their potential use in biological control of insect pests. In this study, twenty four native strains were isolated from Alexandria governorate.  This isolates were identified as 21

Midgut proteases from larval spodoptera littoralis (lepidoptera: noctutoae) [PDF]

, 1992
The presence and properties of proteases present in larval midgut extracts from Spodoptera littoralis was investigated. Trypsin and chymotrypsin activities were found mainly in the midgut lumen while leucine aminopeptidase and dipeptidyl aminopeptidase ...

Innate behaviours shape generalist herbivore host choice and feeding patterns independent of plant defences

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant–herbivore interactions are typically examined through plant defence and herbivore performance, yet individual herbivore behavioural mechanisms underlying these interactions are rarely considered alongside plant traits.

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

Integrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

ANTIBACTERIAL, ANTIVIRAL AND CYTOTOXIC ACTIVITIES OF RHYNCHOPHORUS FERRUGINEUS (COLEOPTERA: DRYOPHTHORIDAE) AND SPODOPTERA LITTORALIS (LEPIDOPTERA: NOCTUIDAE) LARVAL EXTRACTS [PDF]

Journal of the Egyptian Society of Parasitology, 2018
The present study dealt with evaluating the effect of different crude extracts from the larvae of palm weevil, Rhynchophorus ferrugineus and cotton leaf worm, Spodoptera littoralis on different pathogenic strains of bacteria and viruses.

Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle

Integrative Zoology, EarlyView.
Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.

Impact of Cry1AB toxin from transgenic maize (Mon 810) and microbial BT spray (Dipel) on the ecology of a non-target parasitoid, Cotesia marginiventris

, 2008
Cry1Ab toxin derived from Bacillus thuringiensis (Bt) has been used for the control of susceptible lepidopteran species throughout the world. Currently, sprayable Bt formulations and transgenic plants have been used for lepidopteran pest control.
