HPLC of insect honeydew deposits collected from the high speed stickiness detector

Research output: Contribution to specialist publicationArticle

Abstract

The combined effect of the high speed stickiness detector (H2SD) hot plate temperature and the cleaning roll pressure on stickiness measurements and the kinds of sugars sticking on the H2SD's aluminum foil is reported. A subset of 81 honeydew contaminated cotton bales were selected from the set of 150 bales. Twenty seven bales were contaminated mainly by whitefly honey dew (Area 1), 27 bales were contaminated by aphid and whitefly honeydew (Area 2), and 27 bales were contaminated mainly by aphid honeydew (Area 3). Two temperatures of the hot plate were selected, 53°C and 27°C, Two cleaning roll pressures were selected; high cleaning roll pressure (H) and low cleaning roll pressure (L). To determine the sugar composition of the sticky deposits, the sticky spots were collected after the image analysis s stem using wet wipes. Indeed, the Area 3 appeared to be much more sensitive to the hot plate temperature and somewhat less sensitive to the cleaning roll pressure than Areas 1 and 2.
