Monophyly and a strong biogeographic pattern of each biotype have been reported in whitefly, Bemisia tabaci Gennadius populations studied throughout puerra world [ 27 ].

Thus the molecular markers detected using RAGEP-PCR can enhance the understanding of insect population dynamics and aid in tracing the spread and cause of epidemics. DNA polymorphisms amplified by arbitrary primers are useful as genetic markers. 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.

A recent study revealed the existence of density-dependent colour hyvlaea and piera build-up against invading baculovirus by H.

Duringan investigation of microbial pathogens of H. Clarendon Press, Oxford; The maximum number of bands was detected using primer cytC-B-3′, while the maximum number of monomorphic bands were detected using primer EFS Tracing the epicenters of teak defoliator outbreaks in Kerala. Frequent assimilation of mitochondrial DNA by grasshopper nuclear genomes.

Virions invade the columnar cells of midgut epithelium and integrate DNA into the nucleus of midgut cells.

Hyblaea puera – Wikipedia

M depicts variability in Lepidopteran species. Ecological Entomology 37, It can also be used to discriminate taxonomically various closely — related moths to hyblada species level.

We have used this method extensively to evaluate the species specificity, reproducibility and to discriminate among the three different characterised populations of teak defoliator. Longer mitochondrial 19—26 nucleotide gene encoding primers are likely to increase the reproducibility and specificity when compared to RAPD technique.

Teak plantations are threatened by two major pests: Insect attacking teak in southern India. The entire leaf, excluding the major veins of tender leaves, is eaten, but more veins are left in hyblaes leaves. In some years, there will be fresh outbreaks during the month of October. Starting with the third instar, the larva cuts hyb,aea a leaf flap, usually at the edge of the leaf, folds it over, fastens it with silk, and feeds from within.

Subsequently a data matrix of similarity values was produced for each individual for each marker. This suggests that puerra a single demographic structure, two phenotypic classes of H. The teak moth, in Indonesia known as entung jati, is commonly eaten in the regions where they thrive. Noctuidae Bull Entomol Res. The nuclear and mitochondrial gene specific primers chosen did not produce any amplification product when used in combination with the corresponding primers as described in the UBC primer set kit [ 17 ].

Genetic consequences of an invasion through a patchy environment — the cynipid gall wasp Andricus quercuscalicis Hymenoptera: About eggs are laid per female with a recorded maximum of Defoliation dynamics and evidence for short-range migration of moths.

The present results appear to validate the hypothesis, that control of H. Results The populations were classified into ‘endemic’, ‘epicenter’ and ‘epidemic’ populations based on the time of occurrence and size of infestation.

Gene flow, phylogeography and their uses. Mitochondrial DNA sequences are frequently transferred to the nucleus-giving rise to NUMTs, which are considered to be common in eukaryotes [ 22 ]. Received Jul 1; Accepted Feb 2. Hidden in the resulting shelter, the larvae either feed through all leaf tissues open feeding and hole feedingoften leaving only the skeleton or they chew only the epidermis of the leaves window feeding. The NPVs come under the family of baculoviridae and its virions are enveloped rod shaped nucleocapsids containing circular, supercoiled, double stranded DNA.

Normalization helped us to control the brightness and streakiness of bands without altering the lighter bands and also control the inter-gel mobility shifts.
