Feeding Stimulant Mixtures for Spodoptera littoralis (Lepidoptera: Noctuidae)

Journal of Economic Entomology, 1987
Feeding stimulant mixtures (Fest) were developed to improve rate of larval feeding of Spodoptera littoralis (Boisduval) in comparison with Coax. A Fest mixture of cottonseed protein, soybean lecithin, sucrose, and yeast stimulated feeding of fifth instars significantly more than Coax on Styropor lamellae or in a cellulose mixture in choice tests, but ...

Ecdysteroid biosynthesis in larval testes of spodoptera littoralis

Insect Biochemistry and Molecular Biology, 1994
Abstract The ability of testes of the last larval instar of the cotton leafworm, Spodoptera littoralis to synthesise ecdysteroids was investigated. The endogenous ecdysteroid titres of both the testes and the haemolymph differed in their composition and times of peak concentration during this instar.

A Model Simulating Mating Behaviour of Spodoptera littoralis

The Journal of Applied Ecology, 1978
SUMMARY before control measures were simulated in the model. (4) The results suggest that the size of the overwintering population and the time it takes to emerge are critical factors. With a very small overwintering population, the best strategy to ensure establishment on a site is for emigration to be restricted at the beginning of the season and ...

Larvenkot als Eiablage-Deterrens bei Spodoptera littoralis

Naturwissenschaften, 1985
tion because without the added enzyme no growth was found (Table 1, b). The same result was found on testing the aminoglycosides separately; the B. subtills indicator strain was not resistant to any of these. But after adding penicillinase growth was seen, indicating the inactivation of both penicillin and aminoglycosides. No further antibiotics of the

Sex pheromone precursors in Spodoptera littoralis (Lepidoptera: Noctuidae)

Insect Biochemistry, 1987
Abstract Female pheromone gland extracts of Spodoptera littoralis were analyzed for pheromone precursors. Large amounts of fatty methyl esters were found and a positive relationship between the methyl esters and the pheromonal components was observed.

Assessment of housekeeping genes stability for gene transcription regulation analysis of Spodoptera littoralis (Lepidoptera: Noctuidae) under Spodoptera littoralis nucleopolyhedrovirus viral infection

Molecular Biology Reports
Normalization with respect to stable housekeeping genes is important to facilitate gene transcription regulation research and acquire more accurate quantitative polymerase chain reaction (qPCR) data. In the current study, five candidates housekeeping genes of the cotton leafworm, Spodoptera littoralis encoding for Actin (Actin), elongation factor 1 ...

Cirkadiánní změny hemocytů Spodoptera littoralis

2009
Abstrakt This work is a study of the morphology of hemocytes and stability of the basic non-pathological hematological levels during 24 hours. Spodoptera littoralis. (Boisd.) (Lepidoptera: Noctuidae) in the sixth instar was used as the biological model. Light microscopy was the technique used to observe the hemocytes.
