	<span lang=\"EN-US\"><span style=\"font-family:Verdana;\">Preferences of
different oil palm crosses in the station of Pob¨¨ in Benin were tested on </span><i><span style=\"font-family:Verdana;\">Coelaenomenodera</span></i></span><i><span lang=\"EN-US\"> </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">lameensis</span></i><span lang=\"EN-US\" style=\"font-family:Verdana;\"> by monitoring the natural population
for 7 consecutive years. Experiments monitoring of developmental stages of the

Observations were
performed every two weeks on leaves of different ranks (25, 17 or 9) depending
on the degree of defoliation by counting the different stages of insect
development on leaflets. The results showed that the evolution of pest density
is a function of species and the origin of the materials being compared. Population
densities of different stages of </span><i><span style=\"font-family:Verdana;\">C.
