Very high rate of horizontal transfer between organellar and nuclear genomes has been reported in the brown puerz grasshopper, Podisma pedestris L. Geographic structure of insect populations: This appears to be a more practical and economical approach for teak defoliator management when compared with management of the pest in the total plantation area covering thousands of hectares.
Using the mitochondrial RAGEP markers, the average puerz of bands scored for each primer ranged from 6— Noctuidae Bull Entomol Res. The molecular weight of each band was estimated by comparing with a co-migrating bp ladder Amersham.
Five endemic populations, twenty six epicenter populations and seven epidemic populations for the year were included in the study. Intl J Peura Environ Sci. Hyblaea puera Cramer A synnematous fungus of the genus Hirsutella is found to be pathogenic to this pest. Methods in Molecular Biology. Blackwell publishing, Oxford, U.

The UPGMA dendrogram prevails on the assumption that nucleotide substitution rates are same across all branches. Each reaction consisted of 1x Taq buffer with 1. The polymorphic content for nuclear and mitochondrial primers were analyzed using Bionumerics software [ 38 ]. Bar coding animal life: The present results appear to validate the uyblaea, that control of H.
Thailand and is of major economic significance. Similarly the epidemic samples were also collected from insects representing the same life stages at the hyvlaea of collection from each aggressive patch.

Retrieved from ” https: Endemic samples were collected throughout that year based on their stray occurrences in various life stages, whilst epicenter puerq from each aggregated patch were collected only from the insects that attained the same stage of its life cycle at the time of collection in that patch. Such approaches have also been used to study founder events [ 5 ], geographical invasions [ 6 ], small and large scale displacements [ 78 ], including movement of entire population demes [ 9 ], and even altitudinal movements related to habitat patchiness and persistence [ 10 ].
Molecular markers, natural history and evolution. An absolutely specific virus with refractile polyhedral inclusion bodies, staining blue in Giemsa and thick blue hbylaea Buffalo Blacknamed as Hyblaea puera nucleopolyhedrovirus HpNPV is found to be very effective in the biological control of hyglaea pest.

The first and second instars mainly feed on the leaf surface. Only bands showing clear and reproducible patterns were included in the final analysis and these were scored. Pjera were therefore interested in investigating the temporal and spatial relationship among various population groups in Nilambur, Kerala India and address the cause of outbreak at the landscape level. Hyblaea puera Scientific hylaea Kingdom: Subsequently a data matrix of similarity values was produced for each individual for each marker.
About eggs are laid per female with a recorded maximum of Use of RAPDs to examine, for example, population subdivision of the saw toothed grain beetle, Oryzaephilus surinamensis L. They are usually caught for consumption at the cocoon stage, at which point they are easily collected from the ground.
If progenies of the epicenter populations cause the larger epidemics, control of these could prevent major outbreaks. The maximum numbers of bands detected was found using primer SR-J, the minimum numbers using marker N4-N Pupation may some times occur within green leaves of other plants in the under growth, folded or juxtaposed with silk.
Genetic variation in Heliothis in Australia: DNA amplification fingerprinting using very short arbitrary oligonucleotide primers. Since the damage is very severe and effective control measures are unavailable, the puerq scale planting of teak has been abandoned in PNG.
Abstract Background The Teak defoliator Hyblaea puera is hyglaea pest moth of teak woodlands in India and other tropical regions e. During periodical outbreaks, as they occurred at Brown River or Gabensis, the host can be severely or completely defoliated.
