Behaviour
The behaviour and bionomics of the red palm weevil have been investigated in the field. The biology and life history of the weevil have been investigated on five diets, including banana, sugarcane, squash fruit, apple, and palm crown. The rate of development showed great variation depending on the host used. Developmental time was shortest on palm crown, followed by banana, and then squash fruit and apple, and longest on sugarcane. Egg production was the highest on palm crown, being 338 ± 37.24 eggs/female followed by banana, squash fruit, and apple, and the lowest (117. ± 18.9 eggs/female) on sugarcane.
Studies show that this insect is attracted by ethyl acetate, 2-mehoxy.4.vinylphenol, gamma-nonanoic lactone, 4SSS-ferrugineol, 50H and 4me-9-5Kt.

Famous quotes containing the word behaviour:
“When we read of human beings behaving in certain ways, with the approval of the author, who gives his benediction to this behaviour by his attitude towards the result of the behaviour arranged by himself, we can be influenced towards behaving in the same way.”
—T.S. (Thomas Stearns)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
“... into the novel goes such taste as I have for rational behaviour and social portraiture. The short story, as I see it to be, allows for what is crazy about humanity: obstinacies, inordinate heroisms, “immortal longings.””
—Elizabeth Bowen (1899–1973)
