Then, based on these results, the efficacy of the selected doses, Gywas evaluated on the metamorphosis, degree of malformation and reproductive behaviour of S. The sterility of the F 2 population was nearly the same as that of the irradiated parents.

It provided a new insight for the understanding virus—host interaction mechanism. Phylogenetic analysis reveals that S.

These genes were considered to be related to the response of SL cell line to Aza. We took ADN samples from the larval posterior part and we analyzed a fragment of base pairs of the mitochondrial gene cytochrome oxydase I COIto produce a maximum likelihood ML tree by using 62 sequences 29 Colombian haplotypes were used. Our laboratory has successfully generated transgenic reporter and RNAi sensor line of Spodoptera frugiperda Sf21 cells and developed a reversal of silencing assay via siRNA or shRNA guided screening to investigate RNAi factors or viral pathogenic factors with extraordinary fidelity.

spodoptera litura larvae: Topics by

In addition to its high pathogenicity on its natural host Spodoptera eridania, PaV was found to replicate in Spodoptera ochrea Hampson larvae but not in Spodoptera frugiperda Smith larvae. Tobacco cutworm moth Spodoptera lituraan important agricultural pest, causes severe yield losses in many crops. The ovicidal activity was determined against the eggs of S. In a field survey, hzma endoparasitoid Meteorus pulchricornis caused a high percentage of parasitization in populations of S. Ten plants were sampled from each of the 24 plots and for each spodoptdra system, three times a week during the hhama cycle of maize variety BR Full Text Available In the context of the modern agriculture, pest control is important in order to increase productivity in maize Zea maysL.


The results showed that the insecticides and sex pheromone affect the expression levels of the TO genes.

These findings suggest that the factors affecting cannibalism of FAW larvae in laboratory rearings need to be reevaluated, whilst the new technique also show potential to increase the efficiency of both small and mass FAW rearings. Present studies have been carried out to examine two phenomena by the mating experiment under laboratory conditions. After 48 h, the numbers of eggs masses laid on treated and control leaves were recorded and the percentage of oviposition deterrence was calculated.

In this paper, the interactions between M. Our results lay a foundation for studying the role of TO genes in the interaction between insecticides and sex pheromone.

Nymphys of Podisus nigrispinus Heteroptera: Hasil penelitian menunjukkan bahwa aplikasi asap cair secara langsung metode semprot lebih efektif daripada tidak langsung metode celup pakan. We establish useful models that relate experimentally measured biological activities of compounds to their molecular structure.

All predicted TO proteins have two Cysteines that are unique to the N-terminal of the TO family proteins and contain four highly conserved Prolines, two Glycines, and one Tyrosine.

Two anthranilic spodoptega insecticides, chlorantraniliprole and cyantraniliprole, were evaluated as soybean, Glycine max L.

Antioxidant enzyme level response to prooxidant allelochemicals in larvae of the lltura armyworm moth, Spodoptera eridania.


The southern armyworm SAW Spodoptera eridania Cramer is one of the most common armyworm species defoliating soybeans. Enhancing the efficacy of entomopathogenic nematodes by gamma radiation in controlling Spodoptera littoralis larvae.

Qualitative phytochemical analysis has also been performed. Abstract Spodoptera litura S. In order to explore an eco-friendly strategy that could be coupled up with this radio generic method, i. En Colombia ataca el algodonero Gossypium hirsutum L. Full Text Available The allatotropin of S. Full Text Available Rhynocoris fuscipes is a potential predator of many economically important pests in India. There are four dominant bacteria: Impact of sesquiterpenes from Inula racemosa Asteraceae on growth, development and nutrition of Spodoptera litura Lepidoptera: The growth and development, reproduction, and consumption of Spodoptera litura F.


Therefore, the results validate field observations that these two species of Spodoptera are potential pests for cotton. Larvae of the genus Spodoptera spp. We recorded that encapsulation increased blood cell number of both larvae C.

All soybean genotypes evaluated do not exhibit feeding non-preference type resistance to S. Noctuidae, one of the most damaging pests in crops in Brazil. Irradiation had a negative correlation with survival and weight gain during ha,a course of development that in turn bore a positive relation with the increase in radiation dosage.

Insecticidal activity of venomous saliva from Rhynocoris fuscipes Reduviidae against Spodoptera litura and Helicoverpa armigera by microinjection and oral administration. Effects of nickel exposure on testicular function, oxidative stress, and male reproductive dysfunction in Spodoptera litura Fabricius.

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. The changes were visualized by means hqma three spatial indices demonstrating the risks for establishment, number of generations per year and pest abundance according to the temperature conditions. Noctuidae reared on different diets. Full Text Available Nowadays, finding a safe control program is the aim of all researchers.

Eggs were also collected lituraa tree plants but larvae did not complete their development. The histology of the alimentary canal of S. For testing purposes, there was a need for a apodoptera nodal leaf of soybean aged 27 days after planting in each tested material.

Most of the tested genotype showed moderately resistant and others showed susceptible to highly susceptible.
