Falling of asparagus flowers (Asparagus officinalis Linneo.) for the handling of Prodiplosis longifila Gagné in the irrigation of the Chavimochic project

The asparagus, a dioecious plant, usually includes plants of both sexes, though also hermaphrodite ones. The male inflorescences are frequented by adult Prodiplosis longifila, who lay such large amounts of eggs on them that its populations can reach millions of individuals over a lapse of 20 to 30 d...
