In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”.

  • Terrestrial Insects: a Hidden Biodiversity Crisis? 1
    Chapter 7—Terrestrial Insects: A Hidden Biodiversity Crisis? 1 Chapter 7 Terrestrial Insects: A Hidden Biodiversity Crisis? C.H. Dietrich Illinois Natural History Survey OBJECTIVES Like most other elements of the biota, the terrestrial insect fauna of Illinois has undergone drastic change since European colonization of the state. Although data are sparse or entirely lacking for most species, it is clear that many formerly abundant native species are now exceedingly rare while a few previously uncommon or undocumented species, both native and exotic, are now abundant. Much of this change may be attributable to fragmentation and loss of native habitats (e.g., deforestation, draining of wetlands, agricultural conversion and intensification, urbanization), although other factors such as invasion by exotic species (including plants, insects and pathogens), misuse of pesticides, and improper management of native ecosystems have probably also been involved. Data from Illinois and elsewhere in the north temperate zone provide evidence that at least some groups of terrestrial insects have undergone dramatic declines over the past several decades, suggesting that insects are no less vulnerable to anthropogenic environmental change than other groups of organisms Yet, insects continue to be under-represented on official lists of threatened or endangered species and conservation programs focus primarily on vertebrates and plants. This chapter summarizes available information on long-term changes in the terrestrial insect fauna of Illinois, reviews possible causes for these changes, highlights some urgent research needs, and provides recommendations for conservation and management of terrestrial insect communities. INTRODUCTION Insects are among the most important “little things that run the world” (1).

  • BULL THISTLE (Cirsium Vulgare) Description
    BULL THISTLE (Cirsium vulgare) Description: Bull thistle, also referred to as spear thistle, Fuller’s thistle and lance-leafed thistle, is a member of the Asteraceae or sunflower family. Bull thistle can grow 2 to 5 feet tall with numerous spreading branches. Stems of the plant are sparsely hairy, irregularly and spiny winged, green or brownish in color with purple veins. Leaf margins are double dentate (toothed and toothed again), each ending in a lone stiff spine. The leaf surface of the plant has a distinct center vein with slight pubescence on the topside and more underneath. Flower heads are usually solitary on the end of each stem, gumdrop-shaped, one to two inches tall with long, stiff, yellow tipped spines. Flowers are generally bright purple but sometimes white in color. Seeds are light-colored with dark brown to black longitudinal stripes. Seeds are generally 1/16 inch long, oblong, somewhat flattened or curved, with a long, white, hairy plume. Plant Images: Bull thistle Rosette Leaf Gumdrop-shaped flower Distribution and Habitat: This thistle is generally found in the northern and eastern counties in North Dakota and is the least serious of the introduced thistles in the s tate. The plant thrives in moist soils and is less common on sand and pure clay soils. Typical habitats include disturbed or degraded land, such as roadsides, fence rows, overgrazed pastures and rangelands, eroded gullies, ditch banks and vacant lots. Life History/Ecology: Bull thistle is a biennial that reproduces and spreads solely by seed production. Germination of the plant occurs in the spring or during the fall in response to adequate soil moisture.

Cassacia UTAGRI-ECO Via Anguillarese 301, 00123 S. Maria di Galeria (Rome), Italy Received: August 5, 2010 Accepted: November 3, 2010 SUMMARY The Scotch thistle, Onopordum acanthium (Asteraceae) has the Eurasian origin and represents an invasive weed in the USA and Australia. It is a serious problem in pastures, along roadsides, rangeland, etc. The weed is very common in Bulgaria and in 2009-2010 several sites with large populations of O. acanthium have been located. The weekly sur- veys of some of the sites, mainly in the region of Plovdiv, revealed a significant diver- sity of phytophagous insect species, some of which had very high population density. More than 30 species have already been identified and observations on the phenolo- gy and biology of some of them have been conducted. For some of the species, such as endophagous Larinus latus, Lixus cardui, Eublemma amoena, Trichosirocalus briesei, or ectophagous Cassida rubiginosa etc. found during our surveys, there are reports in the lit- erature describing them as having been already introduced as successful biocontrol agents in Australia. Endophagous species like lepidopteran Myelois circumvoluta and Pyroderces argyrogrammos which feed on the stems and the head, and the tephritid flies Tephritis pos- tica and Chaetostomella cylindrica which feed on the capitula, seem quite destructive for the weed, but need to be further studied regarding host specificity.
