spodoptera litura larvae: Topics by

One nodal leaf in each material was placed in a petri dish 15 cm in diameter, which was coated with moist filter paper, and this was later called treatment. Phenotypic identification of soybean lines against armyworm pest resistance Spodoptera litura F. The findings reveal a toxic effect of 3-butenylisothiocyanate rich hot hexane extract of B. First report of Dolichozele koebeleiViereck, Hymenoptera: Infectivity of polyhedra of Spodoptera litura multiple nucleopolyhedrovirus before and after passage through the gut of the predatory stink bug, Eocanthecona furcellata Wolff Hemiptera: Survival rate also decreased significantly with the downregulation of SlituOBP9 followed by feeding with chlorpyrifos.

Given the high similarity in genome content and organization between Spodoptera exigua multiple nucleopolyhedrovirus SeMNPV and Agrotis segetum nucleopolyhedrovirus AgseNPVas well as the high percentages of similarity found between their 30 core genes, the specificity of these NPVs was.

Interactions between Meteorus pulchricornis and Spodoptera exigua multiple nucleopolyhedrovirus.

It lltura designated the Pariacoto virus PaV. Noctuidae in soybean genotypes. An appraisal of certain larval behavioural activities as affected by gamma irradiation of Spodoptera larvae.


Larvae attractiveness was evaluated in different times, and at the end of the experiments the leaf area consumed was quantified. Microinjection of Rhynocoris fuscipes VS was more toxic than its oral administration in Helicoverpa armigera cotton bollworm and Spodoptera litura tobacco cutworm.


This study showed that the selected plant can be a potent source of natural antifeedant, oviposition deterrent, ovicidal and larvicidal activities against field pest S. Leaves surface treated with the rutin deterred oviposition.

The expression of all these genes were down-regulated by starvation, indicating that non-feeding during metamorphosis may be a regulator of glycolysis-TCA pathway in the midgut. Aleiodes laphygmae Viereck Hymenoptera: The reactive distances of the first and third instar normal larvae were 5.

Given their growing importance in the tomato crop, especially for industry, this work aimed to evaluate the feeding non-preference by larvae of Spodoptera frugiperda J. Research involving plants with insecticide activity evolved significantly in the last decades.

The neem efficiency depends on the target insect and on the concentration used. Histological studies of larvae mid-gut profiles of S.

To elucidate its dynamics, the mRNA levels of genes involved in this pathway were examined in the midgut of Spodoptera litura during metamorphosis, and the pyruvate content was quantified. Convolvulaceae extracts and fractions on larvae of Spodoptera f. Correspondingly, mean fecundity rate was reduced at all concentrations compared to control. In the Aza-responsive SSH library, approximately sequences represent 53 different identified genes encoding proteins with various predicted functions, and the percentages of the gene clusters were Here we fed male S.


The feeding behaviour too was significantly affected whereas the dose range less than 4 Krad did not induce such a marked impact. Our results showed a great genetic differentiation K2 distances amongst S. This constitutes a first necessary computationally based step during the design of more bio-friendly repellents that could lead to insights for improving the insecticidal activities of the investigated compounds.

Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap RAL terdiri dari 6 perlakuan jenis pakan dan 10 ulangan. Gamma irradiation did not affect the fecundity of the irradiated parents or of the F 1 and F 2 progeny. Results of gene structure analysis classify the SlitIRs into four types: Among bio-control agents, the entomopathogenic nematodes EPNs appear to be promising due to their great ability for host searching and killing, high reproductive rate, and safety to the non target organisms.

Biological and parabiological control measures of the lepidopteran pest, Spodoptera litura need to be eco-compatible in view of increasing environmental hazards by the chemical pesticides and development of insecticide-resistance in this pest.

The cross infectivity of these two viruses for S. Ten plants were sampled from each of the 24 plots and for each production system, three times a week during the entire cycle of maize variety BR These results demonstrated that azadirachtin induced structural alteration in S.

Toxicity level of L.

Effect of andrographolide on phosphatases activity and cytotoxicity against Spodoptera litura.
