A. Boughton et Hy. Fadamiro, EFFECT OF AGE AND SEX ON THE RESPONSE OF WALKING PROSTEPHANUS-TRUNCATUS (HORN) (COLEOPTERA, BOSTRICHIDAE) TO ITS MALE-PRODUCED AGGREGATION PHEROMONE, Journal of Stored Products Research, 32(1), 1996, pp. 13-20
Studies were conducted on the effect of age and sex on the response of
Prostephanus truncatus (Horn) to its male-produced pheromone using a
laboratory walking bioassay, P. truncatus adults responded to pheromon
e from two days of age, but the level of response significantly decrea
sed gradually from 2-10 days of age: newly-emerged, younger beetles se
emed to respond more quickly and stay longer in the vicinity of pherom
one source than older beetles, There was no significant effect of sex
in the level of response to pheromone, The results are discussed in re
lation to the function of the pheromone: a feeding-based role, The pra
ctical implications of the findings on the pest's monitoring using phe
romone-baited traps are also highlighted. Copyright (C) 1996 Elsevier
