The age and fecundity of female red palm weevils Rhynchophorus ferrugineus (Olivier) captured in food-baited pheromone (4-methyl-5-nonanol) traps placed in coconut plantations of Goa in Western India was assessed in the laboratory. Captured weevils were young and gravid. About 85 per cent of pheromone trap-captured female weevils confined to a celibate life in the laboratory were fertile and laid...
The spatial distribution of red palm weevil, Rhynchophorus ferrugineus Oliv. in coconut plantations was studied by applying a series of statistical tests. Population dispersion parameters and also different dispersion indices were calculated for monthly weevil counts obtained through 40 pheromone (Ferrolure+) trap captures, between August, 1999 and July, 2000. The dispersion parameters, viz. mean-variance...
