Diffusion of Oil Films over Insects [PDF]

open access: yesNature, 1962
CONTACT insecticides are often formulated as solutions in oil and presented as deposits sprayed on to surfaces. The spread of oil on to insects walking over superficial films is an essential process in the action of such a deposit, though the quantities of oil involved are extremely small.
