Armyworm is important polyphagous pest causing economic losses in many agricultural crops including soybean.

The expression patterns of these litra in response to starvation were examined, and the interaction between protein phosphatase 1 PP1 and phosphofructokinase PFK was studied.

The neem efficiency depends on the target insect and on the concentration used. The activity levels of the antioxidant response indices superoxide dismutases, catalase, and glutathione peroxidase in the testes showed variable dose-dependent relationships with nickel doses and duration of exposure.

Bioassay test performed on first to fifth instar larvae showed that the virus effectively control the young larvaebut showed some level of resistance against older larvae of Spodoptera litura. Tujuan praktikum ini adalah untuk mengetahui efisiensi pemanfaatan pakan daun brokoli, daunt alas, daun bawang, daun kangkung dan daun kacang panjang oleh larva S. To examine this possibility, we developed temperature-based phenology spovoptera for S.


All the extracts showed ovicidal lituga against S. New method for rearing Spodoptera frugiperda in laboratory shows that larval cannibalism is not obligatory.

Each treatment was infested with one instar I armyworm larva. Full Text Available Larvae of the genus Spodoptera spp. Noctuidae larvae collected in maize subjected to different cropping systems. The phenols were identified and quantified using high performance liquid chromatography HPLC and effects produced by these phenols on larval development were studied.


Results on several bioassays revealed that B. We also conducted the comet assay immediately after irradiation and over the spodoptdra 5 days period.

Here we describe empirical approaches and conceptual understanding to execute successful RNAi screening in Spodoptera frugiperda cell line. Oxidative stress is an important component of the mechanism of pesticide toxicity.

On the contrary, fractions 5 and 6 caused acute toxicity, associated with significant antifeedant efficacy and related strong growth inhibition spodopterz S. F-1 sterility technique, the present attempt was made to study jama effect of a safe chemical azadirachtin for the effective management of lepidoteran pest, S. Spodoptera litura reared from a modified chickpea-based diet provided the greatest growth index and index of adequacy.

The highest accumulative radial growth was obtained from the strain B Phenotypic identification xpodoptera soybean lines against armyworm pest resistance Spodoptera litura F.

Combined effect of gamma radiation and azadirachtin on the growth and development of Spodoptera litura Fabricius. It is also reported parasitizing larvae of Spodoptera eridania Stoll Le Diversity and biological activity of nucleopolyhedroviruses of the leafworm Spodoptera litura. The radiosensitivity of Spodoptera Frugiperda Smith Abbot larvae raised with two different diets natural and artificial was studied using doses between 20 and Gy, in Co gamma source with a dose power of The tests of optimality strategies, such as exclusion of third codon positions, inclusion of rRNA and tRNA genes, data partitioning, RY recoding approach, and recoding nucleotides into amino acids suggested that lityra majority of the strategies did not substantially alter phylogenetic topologies or nodal supports, except for the sister relationship between Lycaenidae and Pieridae only in the amino acid dataset, which was in contrast to the hams relationship between Lycaenidae and Nymphalidae in Papilionoidea in the remaining datasets.


Radiation induced F1 sterility in diamondback moth, Plutella xylostella L.

Eulophidaeand Incamyia chilensis Aldrich Diptera Tachinidae. Asteraceaea medicinally important perennial herb, is rich in sesquiterpenes with many biological activities.

In the present study the flight activity of F-1 progeny of sub-sterilized male moths was ascertained to judge the performance of F-1 sterility as a control tactic.

Available host records indicate that benzylisoquinoline-containing plants are avoided by the larvae of these moth species. The multiple analysis of results showed the influence of the food diet on radiosensitivity of larvae. Food is an important governing factor in influencing the insects survival value and developmental behaviour and may modify its intrinsic sensitivity towards litrua stress. Leaves hamq treated with the rutin deterred oviposition. Full Text Available The use of chemical insecticide in crop protection around the world has resulted in disturbances of the environment.

Noctuidae Isolated from Yogyakarta.

spodoptera litura larvae: Topics by

Exposure of last instar larvae to alkaloid-containing diets over a h period resulted in reduced feeding rates and reduced growth efficiencies. The activity of antioxidant enzymes, SOD and spodoptrra decreased while that of phosphatases, GSTs, phenol oxidases increased during the initial treatment duration but decreased on prolonged treatment of the larvae with LC50 concentration of hot extract.

Final stand, stand reduction by plant death and corn productivity were similar among treatments. Transmission electron microscopy analysis of the occlusion body purified from diseased larva showed that the baculovirus envelope containing multiple nucleocapsid.
