The cycad aulacaspis scale, Aulacaspis yasumatsui Takagi, is currently found in China, Singapore, Hong Kong, Cayman Islands, Puerto Rico, U.S. Virgin Islands, Hawaii, and Florida (Germain and Hodges 2007). It was originally described from specimens collected on a Cycas sp., in Bangkok, Thailand, in 1972 (Takagi 1977). In recent years, finds have also been reported in California, Georgia, and Nevada (IUCN/SSC Cycad Specialist Group 2009). In 2006, severe outbreaks of cycad aulacaspis scale were reported in South Texas where sago palms, Cycas revoluta Thunb., adorn landscapes and are important ornamental plants for commercial nursery growers (Bográn et al. 2006).

Hypoxia Tolerance In Adult And Larval Cicindela Tiger Beetles Varies By Life History But Not Habitat Association, Mathew L. Brust, W. Wyatt Hoback
Hypoxia Tolerance In Adult And Larval Cicindela Tiger Beetles Varies By Life History But Not Habitat Association, Mathew L. Brust, W. Wyatt Hoback

Flooding exposes terrestrial organisms to severe hypoxia. Among the best-studied insects that are frequently exposed to flooding are tiger beetle (Coleoptera: Cicindelidae) larvae. In previous studies with a limited number of species, a correlation was found between habitat and hypoxia tolerance. In the current study, we examined hypoxia tolerance among third instars of six Cicindela species that vary in habitat association; we also tested adult survival of these species. We found that larvae of the different species survived an average of between 60 and 120 h of submersion in severely hypoxic water at 20°C, with larvae that occur in dry …

The sugarbeet root maggot Tetanops myopaeformis (Röder) overwinters as a freeze-tolerant third-instar larva. Although most larvae are considered to overwinter for only 1 year, some may exhibit prolonged diapause in the field. In the laboratory, they can live for over 5 years using a combination of diapause and post-diapause quiescence. In the present study, the cold survival strategies of these larvae during storage is investigated by measuring their supercooling points in combination with survival data. Supercooling points (SCPs) change significantly during storage, highlighted by a marked increase in the range of SCPs recorded, although the ability to tolerate freezing is …

Protein Digestion In Larvae Of The Red Oak Borer Enaphalodes Rufulus, Damon Crook, Sheila Prabhakar, Brenda Oppert
Protein Digestion In Larvae Of The Red Oak Borer Enaphalodes Rufulus, Damon Crook, Sheila Prabhakar, Brenda Oppert

In the Ozark Mountains of the U.S.A., the red oak borer Enaphalodes rufulus contributes to the destruction of red oaks. To understand nutrient digestion in E. rufulus larvae, digestive proteinases are compared in both larvae fed heartwood phloem and those transferred to artificial diet. The pH of gut extracts is approximately 6.3 in the midgut and foregut and decreases to 5.5 in the hindgut region. The hydrolysis of casein by midgut extracts from E. rufulus larvae fed either artificial diet or phloem from tree sections increases in buffers greater than pH 6.19, with maximum hydrolysis being observed at pH 10.1. …
