Population Dynamics
Unlike other species, the succession of generations of the Bactrocera oleae is not markedly different for the scaling of ovipositioning and longevity of adults. Within a year, generally three to five generations occur, but in many years, a sixth generation can grow in the spring on the olive tree, but does not remain on the tree.
The population size varies throughout the year, but with two peaks: the first in the middle of spring, at the development of the winter generation of adults, and the she second, more intense, in early autumn when the olives are at the highest degree of receptivity, the temperatures drop slightly and the climate becomes wetter. In Sardinia, the larval population peaks typically occur during the months of April–May and September–October.

Famous quotes containing the words population and/or dynamics:
“What happened at Hiroshima was not only that a scientific breakthrough ... had occurred and that a great part of the population of a city had been burned to death, but that the problem of the relation of the triumphs of modern science to the human purposes of man had been explicitly defined.”
—Archibald MacLeish (1892–1982)
“Anytime we react to behavior in our children that we dislike in ourselves, we need to proceed with extreme caution. The dynamics of everyday family life also have a way of repeating themselves.”
—Cathy Rindner Tempelsman (20th century)
