Biology and Feeding Behaviour of Ladybird,Clitostethus arcuatus, the Predator of the Ash Whitefly,Siphoninus phillyreae, in Fars Province, Iran [PDF]
Journal of Insect Science, 2010 Clitostethus arcuatus (Rossi) (Coleoptera: Coccinellidae) is considered as one of the most important natural biological control agents of the ash whitefly, Siphoninus phillyreae (Haliday) (Hemiptera: Aleyrodidae) in Iran. In the current survey, the development, survival, longevity, fecundity, feeding behaviour, and population dynamics of the predator ...

Air Particulates Associated with the Ash Whitefly [PDF]
Journal of the Air and Waste Management Association, 1993 Unusual air particulates are linked to recent heavy infestations of the ash whitefly in California using high-performance liquid chromatography, scanning electron microscopy, optical and infrared microscopy, ion chromatography and X-ray fluorescence spectrometry. The unusual particles apparently are microdroplets of ash whitefly honeydew.

A Cost/Benefit Analysis of the Ash Whitefly Biological Control Program in California
Arboriculture and Urban Forestry, 1997 The ash whitefly {Siphoninus phillyreae) was first identified in California during 1988 and caused widespread defoliation to its primary hosts, ash (Fraxinus species) and ornamental pear (Pyrus species) trees. The ash whitefly caused higher levels of damage to trees in regions with hotter summers and lower damage to trees in regions with cooler summers.
