All are anti larval measures except:
Anti – larval measures are broadly grouped into:
i. Chemicals – larvicidal oils, paris green, temephos
ii. Biolarvicides – fishes like gambusia, lebister etc
b. Source reduction: drainage or filling, deepening or flushing, management of water level, changing the salt content of water & intermittent irrigation
c. Integrated control: bioenvironmental as well as personal protective measures.
DDT is not used as a larvicide. It is an anti-adult measure of vector control.
