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

Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

Plant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

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 ...

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.

Bacillus thuringiensis and its pest control potential as endophyte

Pest Management Science, Volume 82, Issue 7, Page 6931-6939, July 2026.
Bacillus thuringiensis (Bt) systemically colonizes tomato plants as endophyte, inducing midgut damage, fitness reduction and immune suppression in Spodoptera littoralis larvae feeding on Bt‐colonized leaves. The immune suppression enhances the susceptibility to Bt treatments, allowing a synergistic dual use of Bt commercial formulations, by combined ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, Volume 82, Issue 7, Page 7123-7136, July 2026.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

Rhizobia–Bean Symbiosis Increases Root Herbivore Attraction and Growth via Volatile Signals and Enhanced Nutrition

Plant, Cell &Environment, Volume 49, Issue 7, Page 3952-3962, July 2026.
ABSTRACT The symbiosis between nitrogen‐fixing rhizobia and plants is considered mutually beneficial, yet its indirect effects on other organisms remain understudied. We examined how rhizobia symbiosis in Phaseolus vulgaris influences the behaviour and performance of Diabrotica balteata larvae. Specifically, we tested larval preference for nodulated (R+

Olfaction in the Spruce Bark Beetle, Ips typographus [PDF]

, 2011
The bark beetle Ips typographus regularly kills spruce trees in the Palearctic. Spruces are colonized by means of attraction to an aggregation pheromone. Attraction is modulated by anti-attractive volatiles (NHV) from non-host plants.

The Toxicity and Biochemical Activity of Spinosad, Emamectin Benzoate and Dinotefuran on Spodoptera littoralis (Boisd.) [PDF]

Journal of Plant Protection and Pathology
The failure of the traditional insecticides to control cotton leafworm Spodoptera littoralis led to severe losses in different crops as a result of resistance development.

Drought and Herbivory Drive Physiological and Phytohormonal Changes in Soybean (Glycine max Merril): Insights From a Meta‐Analysis

Plant, Cell &Environment, Volume 49, Issue 7, Page 4041-4053, July 2026.
ABSTRACT With climate change, abiotic and biotic stresses such as drought and herbivory are predicted to further diminish agricultural productivity. Soybean (Glycine max [L.] Merrill), a crop of global economic importance, is vulnerable to both. However, the interactive effects of drought and herbivory on soybeans haven't been explored, especially ...
