M depicts variability in Lepidopteran species.

A synnematous fungus of the genus Hirsutella is found to be pathogenic to this pest. Diagnosis of sibling species of Drosophila involved in the colonization of North America by D.

puers The degree of variability observed for RAGEPs also argues that this technique could be useful for a variety of questions, including individual identification, strain pueera and phylogenetic analysis. Larvae hatch in about two days. Patterns of mitochondrial versus nuclear DNA sequence divergence among nymphalid butterflies: Gene flow, phylogeography and their uses.

Use of RAPDs to examine, for example, population subdivision of the saw toothed grain beetle, Oryzaephilus surinamensis L.

Therefore, appropriate strategies should be adopted to control the epicenter populations, which occurs in a smaller area. Predatory insects including wasps, spiders, birds and bonnet macaqueswhich are known to comprise the predator complex of H. By using this site, you agree to the Terms of Use and Privacy Policy.

Authors’ contributions CN and MB performed the molecular studies and are responsible for the interpretation of molecular data whilst TV and VVS performed the field data collection and are responsible for spatial and temporal data interpretation.

Eur J of Entomology. Evidence from the study of the population dynamics of H. There is no evidence of hibernation or aestivation of pupa.

Support Center Support Center. All articles with dead external links Articles with dead external links from April Articles with permanently dead external links Articles with ‘species’ microformats.

If only lower stages were available, i. About eggs are laid per female with a recorded maximum of Defoliation does not kill teak trees, but it results in huge amount of timber loss. Welsh J, McClelland M.

Arbitrarily-primed DNA markers, and involving the polymerase chain reaction PCRhave proved very useful for genetic fingerprinting and for facilitating positional cloning of genes.

Earlier reports involving molecular DNA markers mention the use of these markers in the detection of sibling species of black flies, Simulium spp. Retrieved 8 August Such information should prove valuable in planning and implementing measures to control these pests. Forty-eight species of birds have been recorded as feeding on teak defoliator larvae during the large-scale outbreaks. Published online Feb 2. The UPGMA dendrogram prevails on the assumption that nucleotide substitution rates are same across all branches.


The present results appear to validate the hypothesis, that control of H. It is probably an adaptive trait acquired by the species for surviving in the hostile mangrove environment, since the pupation is not possible in the muddy and inundated soils of mangroves. DNA extraction was performed with a minor modification of isolation and purification protocol as described earlier [ 37 ] being extracted from whole larvae and quantified spectrophotometrically using a spectrophotometer at nm Shimadzu.

Hyblaea puera – Wikipedia

Clarendon Press, Oxford; Longer mitochondrial 19—26 nucleotide gene encoding primers are likely to increase the reproducibility and specificity when compared to RAPD technique. Bar coding animal life: Defoliation does not kill the trees, but does lead to huge timber loss. Hyblaea puera Scientific classification Kingdom: We 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.

Real-time normalization of gel electrophoresis patterns and band position for all the gels was based on the reference system for the species-specific bands.

Duringan investigation of microbial pathogens of H. During late July or September, the population declines to the endemic level.
