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)
“I look on it as no trifling effort of female strength to withstand the artful and ardent solicitations of a man that is thoroughly master of our hearts. Should we in the conflict come off victorious, it hardly pays us for the pain we suffer from the experiment ... and I still persist in it that such a behaviour in any man I love would rob me of that most pleasing thought, namely, the obligation I have to him for not making such a trial.”
—Sarah Fielding (1710–1768)
“... 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)
