Ecological Engineering for conservation of
Bio-control agents
To make the environment better suited for the
buildup of existing beneficial fauna through manipulation of biotic and abiotic
factors of ecosystem is called ecological engineering.
Ecological engineering
for conservation of bio-control agents is manipulation of the habitat in the
crop ecosystem for buildup of beneficial bio-control agent.
Ecological
engineering is based on ecological principles in which the environment of
Agro-eco-system is made suitable for the better survival of bio-control
agents/beneficial fauna. It’s a kind of human intervention to manipulate the
habitat better suited for the buildup of bio-control agents.
For the
better survival and build up of bio-control agents in Agro-eco-system, the
following things are required:
1. Food in
form of pollen and nectar for adult bio-control agents.
2. Shelters
such as overwintering sites, moderate micro-climate, etc.
3. Alternate
hosts are required when primary hosts are not present.
