Small scale field trial with polystyrene beads for the control of mosquito breeding

Mosquito breeding sites confined within four walls as cesspits were selected to carry out the trial with expanded polystyrene beads for the control of mosquito breeding. A comparative study between the use of the beads and oil has also been carried out. Results revealed the superiority in effectiveness of beads over oil for the control of mosquito breeding. Mosquito catches from cesspits treated with polystyrene beads dropped to zero soon after application of the beads and remained so throughout five months observation period.
