The Beetles Of Northeastern North America: A Manual Of The Coleoptera Found In Northeastern North America, Norville M. Downie, Ross H. Arnett Jr.

Insecta Mundi

Twenty years in the making, this book is more than just a replacement for Blatchley's “Coleoptera of Indiana.” It offers totally revised keys to the families, genera, and species of beetles found from the Arctic to the Potomac, west to the Mississippi. Each family, genus, and species is described. The books contain about 4,000 illustrations enhancing the descriptions of 7,500 included species.

These books are designed for use by amateurs and specialists. The non-entomologist (ecologists, wildlife managers, extension agents, and teachers) will find it useful not only to quickly determine the taxonomic name of any beetle that lives in the …

A new species of an endemic tenebrionid beetle, Opatrinus armasi, is described from the environs of San Antonio de los Banos, Havana Province. The new species is found living syntopically in this area with the more widespread 0. pullus. Comparisons with various populations of this latter species are made. Photographs of the beetles, drawing of pronotum, as well as males genitalia of both species are given.

Scientific Note: Phenacoccus Parvus Morrison, A Possible Injurious Mealybug Recorded For The First Time From Florida (Homoptera:Coccoidea: Pseudococcidae), D. J. Williams, A. B. Hamon

Insecta Mundi

Phenacoccus parvus Morrison is recorded from Florida for the first time. Specimens were collected at Miami on Cestrum diurnum (Solanaceae),l-IX-1883 by J. Frankel, and on an unidentified plant of the family Apiaciae (Umbelliferae), 4-XI-1983, by D. Barger. These records are also the first for the continental US. Phenacoccus parvus material from Hawaii on Sida fallax has been examined.

This mealybug was described from the Galapagos Islands. Williams and Cox (1984) synonymized the name P. surinamensis with P. parvus. This species has been recorded from the West Indies, Central America, and South America on many hosts (Williams and Granara de …

New Genera Of Tephritidae (Diptera) From Brazil And Dominican Amber, With Phylogenetic Analysis Of The Tribe Ortalotrypetini, Allen L. Norrbom

Insecta Mundi

The tribe Ortalotrypetini (Trypetinae) is expanded to include four genera, whose phylogenetic relationships are analyzed. The following are recognized: Ortalotrypeta Hendel, Cyaforma Wang, Neortalotrypeta, n. gen., proposed for N. bicolor, n. sp., from Brazil, and Protortalotrypeta, n. gen., proposed for P. grimaldii, n. sp., which is described from a specimen in amber from the Dominican Republic. Ortalotrypeta ziae, n. sp., from Taiwan, is described, and lectotypes are designated for 0. gigas Hendel and 0. idana Hendel. O. macula Wang and O. tonkinensis Zia are transferred to Cyaforma.

Scientific Note: New Synonymy In The Genus Dacne Latreille (Coleoptera: Erotylidae), Paul E. Skelley

Insecta Mundi

Dajoz (1988) recently described Dacne montana from Colorado. In an attempt to identify this species, I have compared the description with specimens of previously described Dacne, including paratypes of Boyle's species and specimens identified by Boyle (1956) in his revision. Dajoz's habitus illustration of Dacne montana is identical to paratypes of Dacne cyclochilus Boyle; the male genitalia match Boyle's drawing of those of D. cyclochilus; and the female genitalia match Boyle's illustration of those of Dacne californica (Horn).

Neotype Designations For The Type Species Of Phidippus (Araneae: Salticidae), G. B. Edwards

Insecta Mundi

Life Or Death In Amber?, Robert E. Woodruff

Insecta Mundi

Because I've studied Dominican Amber for 25 years, this article began as a simple request for me to review a recent book: "Life in Amber" by George 0. Poinar, Jr., Stanford university Press. 350p.; 37 color and 154 black and white photos; 8 maps. Publication date: Sept. 25, 1992. Price: $55.00. It was soon obvious that the volume and nature of my comments precluded a simple review. My paraphrased title is a minor semantic difference with Dr. Poinar's, although I doubt that he would write of "Life in Egyptian Tombs". Creatures preserved for 30 to 40 million years should at …

Fecundity And Fertility Of Rhynchophorus Cruentatus (Coleoptera: Curculionidae), Thomas J. Weissling, Robin M. Giblin-Davis

Department of Entomology: Faculty Publications

The palmetto weevil (R. cruentatus F.) breeds in a variety of stressed or dying palms (Giblin-Davis & Howard 1988, 1989). These large (1.9 - 3.0 cm long) weevils are associated with the native cabbage palmetto, Sabal palmetto (Walter), in Florida (Woodruff 1967). Semiochemicals emanating from stressed or dying palms and male conspecifics (Weissling et al. 1992, 1993, 1994, Giblin-Davis et al. 1994) are attractive to R. cruentatus adults. Although not fully understood, mating apparently takes place on dying palms and females lay their eggs in the leaf bases or directly into the wounds of the host. Larvae develop primarily …

Patterns Among Host Plants Of Potato Leafhopper, Empoasca Fabae (Homoptera: Cicadellidae), William O. Lamp, Gary R. Nielsen, Stephen D. Danielson

Department of Entomology: Faculty Publications

Ecological characteristics of potato leafhopper, Empoasca fabae (Harris), including polyphagy, suggest that non-economic plant species in the landscape may be important to its population ecology. The objectives of this study were to compile a host list, to ascertain taxonomic and ecological patterns within the list, and to determine host utilization in non-crop habitats. The host plant list included 220 species in 100 genera and 26 families. Fabaceae represented 47% of the genera and 62% of the species. Yet, the list includes a diversity of taxonomic groups within the class Magnoliopsida, representing highly divergent chemistry and morphological types. Ecological classifications, based …

Passive Trap For Monitoring Codling Moth (Lepidoptera: Tortricidae) Flight Activity, Thomas J. Weissling, Alan L. Knight

Department of Entomology: Faculty Publications

A new passive trap, constructed of rigid, clear plastic panes (0.3 m by 0.3 m), coated with an STP Oil Treatment film as an adhesive, was developed for monitoring codling moth, Cydia pomonella (L.), movement within and between orchard canopies. Tests showed that the trap was effective in recapturing released codling moth adults, that the adhesive was not attractive to moths, and that the adhesive was still effective after remaining on a trap for 1 wk in the field. Field experiments demonstrated that the passive pane-trap method is as efficient for catching moths as molasses-baited traps but that it is …

Screening Sunflower For Tolerance To Sunflower Midge Using The Synthetic Auxin 2,4-Dichlorophenoxyacetic Acid, Gary J. Brewer, Marc D. Anderson, N. V. Rama Raje Urs

Department of Entomology: Faculty Publications

The sunflower midge, Contarinia schulzi Gagné, causes economic damage by inducing abnormal growth in infested heads (capitula) of sunflower, Helianthus annuus L. The primary objective of this study was to determine whether sunflower midge damage could be simulated and whether that simulated damage could be used to select midge-tolerant sunflower germplasm. An additional objective was to develop a quantitative alternative to the scoring systems used to visually estimate damage. Sunflower plants were treated by injecting buds with the synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D), which resulted in a distortion of the head morphology that was similar in appearance to the damage …

Population Genetics And Gene Variation In Primary And Secondary Screwworm (Diptera : Calliphoridae), David B. Taylor, Richard D. Peterson Ii

Department of Entomology: Faculty Publications

Allozyme variation in screwworm, Cochliomyia hominivorax (Coquerel), and secondary screwworm, C. macellaria (F.), populations from northwest Costa Rica was examined . Variability was observed in 11 of 13 enzyme loci and the frequency of the most common allele was <0.95 for 5 loci in screwworm . In secondary screwworm, 12 of 13 loci were variable and the frequency of the most common allele was <0.95 for 6 loci . Expected heterozygosities were 0.149 and 0.160 for screwworm and secondary screwworm, respectively. Goodness-of-fit statistics for Hardy-Weinberg equilibrium and Wrights F statistics indicated that both species are panmictic with no evidence of population substructuring. Nei ' s genetic distances were 0.000–0.001 for intraspecific comparisons and 0.899–0.916 for interspecific comparisons. The data indicate a high level of gene flow between populations within each species.

Rice Pests In The Ivory Coast, West Africa: Farmers’ Perceptions And Management Strategies, A. A. Adesina, D. E. Johnson, E. A. Heinrichs

Department of Entomology: Faculty Publications

An understanding of farmers’ perceptions of pests and their existing pest control methods can make an important contribution to the development of effective integrated pest management strategies. While the relatively successful rice IPM technologies in Asia have been extensively documented in studies examining farmers’ pest perceptions and management practices, studies examining, specifically, perceptions and management practices of West African rice farmers are rare. This may reflect the more limited success to date in the implementation of rice IPM strategies in the region. This paper describes rice pests, pest perceptions, and management practices of smallholder rice farmers in the Ivory Coast. …

Flight Behavior And Seasonal Trapping Of Rhynchophorus Cruentatus (Coleoptera: Curculionidae), Thomas J. Weissling, Robin M. Giblin-Davis, Barbara J. Center, Tak Hiyakawa

Department of Entomology: Faculty Publications

Flight behavior, activity, and seasonal variation in capture of Rhynchophorus cruentatus (F.) were investigated. Response of R. cruentatus to traps baited with palm tissue was assessed at four locations in Florida over a 12- to 18-mo period. Capture of weevils varied by location and through time. Average temperature, the difference between high and low temperature, and total rainfall during trapping periods were not correlated with seasonal trends, but capture peaked in the spring following rise in temperature. Preflight behaviors of R. cruentatus were consistent for all weevils tested. Weevils preparing for flight first wipe their rostrum with the prothoracic legs, …
