Abstract
Insects are the biological supporting system of our world as they make
up about 80 per cent of the known animal species and have a 400-million-year
evolution record. They play a key role in nutrient recycling, soil turnover and
pollination of vital food crops and therefore, their preservation is
inseparably associated with ecological stability in the world and food security
among human beings. The growing threats in insect biodiversity is driven by
human activities, including habitat fragmentation, the neurotoxic effects of
synthetic pesticides, competition among invasive species, and the increasing
impact of climate change. Ectothermic insects display distinctive physiological
sensitivity to changing thermal schedules, and not only do these changes disrupt
one or more metabolic processes, but they also alter phenological synchrony.
The synthesis measures the modern conservation systems, where a change in
perspective is necessary and advancement towards other forms of species-based
models to a multi-scalar approach. Some of the main interventions discussed are
restoration of habitat, the creation of urban corridors that are Bugs-Welcome
and the integration of sustainable agricultural methods like the use of
Integrated Pest Management (IPM) to reduce collateral damage to desirable
entomofauna. Besides, the article emphasises the importance of the latest
technological achievements, including population genomics and the use of
cryopreservation-like techniques, which are demonstrated by the recent
development of Monarch butterfly germplasm storage, as an essential tool of
genetic diversity protection. Through a comparison with successful case studies
and revealing gaps in the current policies in protecting areas, this review
identifies needs of an ecocentric legislation and global collaboration to
inoculate the ecosystem services.
