Abstract
Flowers are completely dependent on the vectors to move pollen. An abundance of insect vectors or pollinators determines a greater proportion of early flowers, results in greater quality of fruit with earlier and more uniform crops. Insect pollinators face many important pressures due to environmental changes such as climate change, alien species, pest, pathogens, fire, grazing and mowing etc. Many anthropogenic constraints such as land-use change (habitat loss, degradation and fragmentation), use of pesticides, electro-magnetic pollution, genetically modified crops, are primarily responsible for the decline of insect-pollinators. In this review, we have focused on many challenges faced by insect pollinators through environment and human interventions. Research on socio-cultural aspects of insect pollinators’ declines is increasing but further research is required.
