This study was conducted to better understand the life history of Parthenolecanium corni (Bouché) and Parthenolecanium quercifex (Fitch) (Hemiptera: Coccidae), and to develop degree-day models for crawler emergence of the two soft scale species in Georgia, North Carolina, South Carolina, and Virginia. Both species were univoltine in the southeastern United States. In South Carolina, eggs hatched from mid-April to early June; second instars began to appear in September and migrated to twigs to… Expand
Natural Enemy Communities and Biological Control of Parthenolecanium spp. (Hemiptera: Coccidae) in the Southeastern United States
The species composition, seasonal ecology, and impacts of parasitoids and predators of Parthenolecanium corni and P. quercifex in the urban landscapes of Georgia, North Carolina, South Carolina, and Virginia are documented. Expand
The spread of the non-native pine tortoise scale Toumeyella parvicornis (Hemiptera: Coccidae) in Europe: a major threat to Pinus pinea in Southern Italy
The hypothesis of an ongoing shift of parasitoid populations from other indigenous soft scales to the invasive one is confirmed, as the low level of natural control was ineffective in hampering the spread of T. parvicornis, and preventing the dieback of local pine species, Pinus pinea, as observed in all invaded areas.

Review of the direct and indirect effects of warming and drought on scale insect pests of forest systems
  • S. Frank
  • Biology
  • Forestry: An International Journal of Forest Research
  • 2020
Warming and drought are often coincident in urban forests and predicted to co-occur in many parts of the world under climate change scenarios, and the individual and interactive effects of these factors require further research to inform predictions and management of scale insect pests. Expand
Water availability drives urban tree growth responses to herbivory and warming
Urban forests provide important ecosystem services to city residents, including pollution removal and carbon storage. Climate change and urbanization pose multiple threats to these services. However,Expand


Life History and Natural Enemy Associations of Calico Scale (Homoptera: Coccidae) in Kentucky
Seasonal phenology of calico scale, Eulecanium cerasorum (Cockerell), was monitored for 3 yr on various deciduous tree species in central Kentucky to confirm that targeting crawlers with insecticides during late May or June would not coincide with peak flight activity of the scale’s primary parasitoids.

Observations on the biology of Parthenolecanium rufulum in northeastern Italy, with a redescription of the first and second instar females.
The pattern of phenology in Italy is about a month earlier than in central Europe, and the 1 st and 2 nd instar females of P. rufulum are redescribed and illustrated; no males were noted and reproduction was parthenogenetic. Expand
Natural Enemies of Oak Lecanium (Homoptera: Coccidae) in Eastern Virginia
Two Coleoptera were identified: Hyperaspis signata (Oliver) (Coccinellidae) and Tricorynus confusus (Fall) (Anobiidae), the latter species being observed for the first time as a predator. Expand
General Biology and Current Management Approaches of Soft Scale Pests (Hemiptera: Coccidae)
The economic importance, biology, and management of soft scales are summarized, focusing on pests of agricultural, horticultural, and silvicultural crops in outdoor production systems and urban landscapes and on crawlers of most univoltine species. Expand
Descriptions and Illustrations of the First Instars of Parthenolecanium corni (Bouché) and Parthenolecanium quercifex (Fitch) (Hemiptera: Coccidae)
Key characters in distinguishing P. corni from P. quercifex are the absence of large (>5 μm) in the dorsal pore pattern. Expand
Seasonal Occurrence, Phenological Indicators and Mortality Factors Affecting Five Scale Insect Species (Hemiptera:Diaspididae, Coccidae) in the Urban Landscape Setting
Seasonal appearance of five species of scale insects in the urban landscape along with flowering phenology of 40 plant species were systematically monitored during 1997, 1998, 1999 and 2000 in Athens, GA. Expand
A Study of the European Fruit Lecanium Scale, Lecanium corni, on Prune
The population fluctuations of the scale insect Lecanium corni Bouche, a common orchard pest, were studied and two factors, the parasites and high June temperatures, appear to create sufficient environmental resistance to hold the pest below the economic injury level in the coastal area without the use of insecticides.

Size and fecundity of soft wax scale (Ceroplustes destructor) and Chinese wax scale (C. sinensis) (Hemiptera: Coccidae) on citrus
Adult soft wax scale Ceroplastes destructor and Chinese wax scale C. sinensis (Hemiptera: Coccidae) infesting citrus orchards in Northland, New Zealand were sampled to determine their size, fecundityExpand
Life table of the hemispherical scale, Saissetia coffeae (Walker) (Hemiptera: Coccidea)
The hemispherical scale, Saissetia coffeae (Walker) (Hemiptera: Coccidae) is one of the most important pest attacking olive trees in Egypt and the durations of the adult longevity were 6±0.67, 8.7± 0.82 and 8.9 ± 0.74 days at 18, 24 and 30 o C, respectively. Expand
