TRT 16:00

This film provides instruction for rearing and handling anopheles mosquitoes in an insectary while a woman simultaneously demonstrates all of the actions steps described. Mosquitos in stock cages feed on a rabbit put into the cage so that they feed and can lay eggs. The woman rinses the pan of eggs into a larval pan and provides food of dog biscuit crumbs and yeast when 75% of the eggs are hatched. The film shows a detailed close view of the mosquito life cycle and then shows how adults are lightly blown into the sorting cage. The woman is then seen selecting out adult females from the sorting cage with an aspirator and placing them in small glass jars topped with pieces of cellucotton filled with syrup and water. The narrator believes insectary rearing of mosquitoes for malaria transmission studies illustrates ways in which scientists depend on one another.

KEY WORDS: Malariologist, entomologist, Anopheles mosquito breeding, laboratory, eggs, larvae, pupae, larval pan
