Based on the primary data covering the period 1951-2019, the study highlights the problems of Brain Drain, Capital Drain, and Loss of Demographic Dividend. As many as 96.62 percent of the people migrated from the age group of 15 to 45 years. Most of the youngsters were migrating just after completing secondary level education. Unemployment, desire to earn more, better living conditions and good administration at the destination, and peer pressure were the main reasons for the migration of the people from rural Punjab. Two-thirds of the migrants sent no remittances to their families. Due to the high cost of migration and low remittances, two-thirds of the households were under debt.

Sterile insect releases to manage or eradicate pests have been deployed increasingly in many countries against diverse targets but have not previously been seriously considered in New Zealand The increasing cost of incursions of exotic species warrants a reconsideration of the potential for any approach that can help to defend New Zealand The success of the sterile insect technique is dependent on adequate understanding of pest biology techniques for mass rearing of sufficient numbers to overcome the target population mass sterility (with excellent quality assurance) competitive fitness of released insects and release systems that ensure effective spatial targeting Legislative hurdles such as the HSNO Act (1996) may need attention to enable this approach for insects that have arrived after 1998 The first use of the sterile insect technique in New Zealand is against the painted apple moth and is a useful case study to demonstrate the potential of the approach in biosecurity
