Effects of nucleopolyhedrovirus based product on Spodoptera littoralis

, 2008
Nucleopolyhedroviruses (NPV) are considered among the most promising microbiological control agents for Spodoptera littoralis (Boisduval) (Lepidoptera Noctuidae). In a first laboratory experiment, a new SlNPV-based formulation was compared with a conventional Bt toxin product in order to evaluate its potential role as bioinsecticide for the short-term ...

Intermediates of stigmasterol metabolism in spodoptera littoralis

Steroids, 1989
Stigmasterol-24,28-epoxide, 22E-stigmasta-5,22,24(28E)-trien-3 beta-ol, and 22E-cholesta-5,22,24-trien-3 beta-ol were identified as normal metabolites of [3H]stigmasterol in Spodoptera littoralis larvae. Relative concentrations of all three of these metabolites increased when a diazasterol inhibitor was fed in combination with stigmasterol in the ...

Olfactory discrimination conditioning in the moth Spodoptera littoralis

Physiology & Behavior, 2001
We used a proboscis extension reflex (PER) to study the olfactory discrimination capability in the moth Spodoptera littoralis. Already after a single experience, moths were capable to discriminate a rewarded from an unrewarded odor. In the first experiment, when rewarded and unrewarded odors were substituted for each other, moths were able to undergo ...

Action of brassinosteroids in the cotton leafworm Spodoptera littoralis

Insect Biochemistry and Molecular Biology, 2002
The two native plant hormones 24-epibrassinolide and 24-epicastasterone showed 50% competition for binding at IC(50) of 1-3.6 microM with [(3)H]ponasterone A using cultured imaginal wing discs from last-instar larvae of the cotton leafworm, Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae).

Sex pheromone of the cotton leafworm, Spodoptera littoralis

Journal of Insect Physiology, 1974
Abstract cis -9, trans -11-Tetradecadien-1-ol acetate (A) and cis -9, trans -12-tetradecadien-1-ol acetate (B), the same compounds as the female sex pheromone of Spodoptera litura , were identified as major components of the female sex pheromone of the cotton leafworm, Spodoptera littoralis .

Attraction of Spodoptera littoralis Larvae to Colours

Nature, 1973
DURING a research programme on phagostimulants1–3 for the larva of the Egyptian cotton leafworm, Spodoptera littoralis Boisd., it was found that their incorporation into poison baits did not sufficiently improve the latter's attractivity. Further stimuli, for example optical ones, seemed to be needed.

Functional analysis of an immune gene of Spodoptera littoralis by RNAi

Journal of Insect Physiology, 2014
Insect immune defences rely on cellular and humoral responses targeting both microbial pathogens and metazoan parasites. Accumulating evidence indicates functional cross-talk between these two branches of insect immunity, but the underlying molecular mechanisms are still largely unknown. We recently described, in the tobacco budworm Heliothis virescens,

The in vivo production of Spodoptera littoralis nuclear polyhedrosis virus

Journal of Virological Methods, 1998
The in vivo production of the nucleopolyhedrovirus (NPV) of the Egyptian cotton leafworm Spodoptera littoralis was studied experimentally. Larvae (7 days old) of 30-50 mg were experimentally infected with a range of NPV doses then harvested alive at various times after dosing to determine the effect of dose and incubation time on NPV productivity ...
