Immature and adult insects representing 8 orders, 86 families, and 338 species were collected from broom snakeweed (Xanthocephalum sarothrae) or threadleaf snakeweed (X. microcephala) in the western half of Texas and eastern New Mexico during 1976 and 1977. Most of the 46 sampling locations were visited three times each year. Insects were collected by hand, sweep net, or D-Vac. The aboveground vegetation of 30 plants and the root systems of 10 plants were sampled at each location during most… 

Biology of Heilipodus ventralis (Coleoptera: Curculionidae), an Argentine Weevil for Biological Control of Snakeweeds (Gutierrezia spp.) in the United States

Abstract The Argentine root-boring weevil Heilipodus ventralis (Hustache) is a candidate for biological control of the perennial snakeweeds Gutierrezia sarothrae (Pursh) Britton and Rusby and G.

Host Specificity of the Argentine Root-Boring Weevil, Heilipodus ventralis (Coleoptera: Curculionidae), a Potential Biocontrol Agent for Snakeweeds (Gutierrezia: Asteraceae) in Western North American Rangelands—U.S. Quarantine Tests

H. ventralis, the root-boring weevil, appears sufficiently host specific for field release in North America, and is the first introduced biocontrol agent to be approved for release in a continental area to control a native weed.

Liorhyssus hyalinus (F.) (Hemiptera: Rhopalidae) in the Western United States: New Host Records, Host-Plant Range, and Comments on Use of the Term “Host Plant”

A more consistent and restrictive interpretation of the term “host plant” is recommended for this nearly cosmopolitan, polyphagous rhopalid, or scentless plant bug, based on fieldwork and a review of the literature.

Phytophagous Arthropods Associated with Parthenium hysterophorus (Asteraceae) in North America

Comparisons showed that the fauna of P. hysterophorus is most similar to that of ragweeds (Ambrosia spp.), and six insect species that were shown to be stenophagous were shipped to Australia for further testing and possible field release.

Broom snakeweed (Gutierrezia sarothrae) dispersal, viability, and germination

Greenhouse experiments compared the influence of water application interval and water amount on broom snakeweed germination and seedling survival and suggest that optimum germination occurs when soils are maintained at a minimum soil matric potential (Ψm) > −180 kPa for at least 4 d.

ABSTRACT: Adult flies of Conioscinella nuda (Adams) were collected from four native grass species, big bluestem (Andropogon gerardii Vitman), little bluestem [Schizachyrium scoparium (Michx.) Nash],

Collections of Epiblema rudei Powell, 1975, (Tortricidae) in Utah

In 2011 and 2013, MM collected several unknown moths during routine trapping for pest Tortricidae in a tree-fruit orchard in Utah, USA, near Utah Lake (Table 1, Fig. 1). The moths were collected in

Population cycles of broom snakeweed in the Colorado Plateau and Snake River Plains.

Although density of mature plants did not change much during the middle part of the study, the change in snakeweed cover was correlated with spring and total precipitation, reflecting increase and decrease in size of plants in response to precipitation.

Life history of Mecideamajor with descriptions of nymphal instars (Hemiptera, Heteroptera, Pentatomidae)

The times of occurrence and abundance of the eggs, nymphs, and adults suggest this species is bivoltine with the possibility of a third generation.



Broom Snakeweed Control with Tebuthiuron

Broom snakeweed was effectively controlled for at least 3 years with 0.6 kg a.i./ha (80% wettable powder) tebuthiuron on the Southern High Plains. Total herbage production decreased following broom
