Arai, T. 2002 Attractiveness of sex pheromone of Pseudococcus cryptus Hempel (Homoptera : Pseudococcidae) to adult males in a citrus orchard.. Applied Entomology and Zoology. Tokyo 37(1): 69-72.
Notes: The attractiveness of the sex pheromone of Pseudococcus cryptus to adult males and natural enemies was tested in citrus orchards in 1999 and 2000. Males were caught by the pheromone trap during two periods in 1999 and three periods in 2000, whereas natural enemies were not attracted in either year. When seasonal degree-day accumulations reached 302 DD above a base of 10degreesC from the periods that males were trapped, the first instars emerged.
