Abstract:Taylor's power law was used to develop a fixed-number sampling plan for Brachycorynella asparagi (Mordvilko) on mature asparagus, Asparagus officinalis L., foliage. For control decisions, we recommend taking 141 primary branch samples and extracting the aphids from the foliage with Berlese-Tullgren funnels. The time required to do the sampling was determined. A new method of extracting aphids in paper bags was unsatisfactory, mainly because identifying and counting aphids mixed with plant debris and dirt were difficult. Aphids had an aggregated distribution and number of aphids within fields tended to increase from west to east.
