Nine resistant teak clones identified based on a four-year field survey were taken for confirmation of its resistant nature against teak defoliator, Hyblaea puera, by comparing the feeding preference with most susceptible and moderately susceptible teak clones under controlled conditions in a choice and no-choice situation. Three clones showed minimum or negligible feeding damage without significant variation under choice and no-choice situation. The study also demonstrated the physical and chemical variations in resistant and susceptible clone leaves, which may interfere with the feeding behaviour of H. puera. Observed results call for a detailed study on genetic variation in physical and chemical properties in tree clones of economic importance for exploitation to develop resistant strains of trees against key pests through breeding as well as genetic engineering/transformation.

Using the district data on industrial production for the organised manufacturing sector (OMS) in Tamil Nadu the paper identifies areas which have experienced jobless growth. Examining the inter-district variations in the performance of OMS units in the state, the paper identifies districts which have fared better both in terms of labour productivity and employment gains, distinguishing in the process the districts which have lagged behind in this regard. The findings of the study support the hypothesis of job displacement expected to prevail in an atmosphere of competitive economic environment. Some data problems requiring policy attention have been identified which, if addressed, contribute to a more effective generation of data at the district level.References

Work life balance becoming an area of growing concern in the Information Technology (IT) and Information Technology Enabled Services sector (ITeS). The present paper provides a greater understanding of the work-life balance of women employees in IT and ITeS industries. An experiential survey of 80 IT employees and 80 ITeS employees was carried out. Both the sub-sectors were evaluated on five sub-scales- workload and responsibility, work environment, feelings about work, family dependents and absence from work. The sector wise regression analysis demonstrated that feelings about work, family dependents and absence from work are strong contributors to a sense of balance for an employee. However, no significant relationship has been obtained between work environment and work-life- The Leaf-Feeding Geometrid Isturgia disputaria (Guenee)-A Potential Biological Control Agent for Prickly acacia, Vachellia nilotica subsp. indica (Benth.)

Prickly acacia (Vachellia nilotica subsp. indica), a native multipurpose tree in India, is a weed of National significance, and a target for biological control in Australia. Based on plant genetic and climatic similarities, native range surveys for identifying potential biological control agents for prickly acacia were conducted in India during 2008-2011. In the survey leaf-feeding geometrid, Isturgia disputaria Guenee (syn. Tephrina pulinda), widespread in Tamil Nadu and Karnataka States, was prioritized as a potential biological control agent based on field host range, damage potential and no choice test on non target plant species. Though the field host range study exhibited that V. nilotica ssp. indica and V. nilotica ssp. tomentosa were the primary hosts for successful development of the insect, I. disputaria, replicated no - choice larval feeding and development tests conducted on cut foliage and live plants of nine non-target acacia test plant species in India revealed the larval feeding and development on three of the nine non-target acacia species, V. tortilis, V. planiferons and V. leucophloea in addition to the V. nilotica ssp. indica and V. nilotica ssp. tomentosa. However, the proportion of larvae developing into adults was higher on V. nilotica subsp. indica and V. nilotica subsp. tomentosa, with 90% and 80% of the larvae completing development, respectively. In contrast, the larval mortality was higher on V. tortilis (70%), V. leucophloea (90%) and V. planiferons (70%). The no-choice test results support the earlier host specificity test results of I. disputaria from Pakistan, Kenya and under quarantine in Australia. Contrasting results between field host range and host use pattern under no-choice conditions are discussed.Keywords
