Stings Of Ants Of The Tribe Ectatommini (Formicidae: Ponerinae), Charles Kugler

Insecta Mundi

The sting apparatus anatomy is described and compared for 24 species in six of the 9 extant genera of Ectatommini: Paraponera, Acanthoponera, Gnamptogenys, Ectatomma, Proceratium, and Discothyrea. Phylogenetic analysis sorts 15 species of Gnamptogenys into four species groups. Phylogenetic analyses on the six ectatommine genera suggest that: 1) Gnamptogenys and Ectatomma are sister genera, 2) Proceratium and Discothyrea are sister genera, 3) Acanthoponera may be more related to Gnamptogenys and Ectatomma than to the others, and 4) Paraponera may not belong with the other five genera.

Stimulation Of Pheromone Biosynthesis In The Moth Helicoverpa Zea: Action Of A Brain Hormone On Pheromone Glands Involves Ca2+ And Camp As Second Messengers, Russell A. Jurenka, Emmanuelle Jacquin, Wendell L. Roelofs

Russell A. Jurenka

Isolated abdomen and pheromone gland bioassays were utilized to determine the physiological action of the pheromone-biosynthesis-activating neuropeptide (PBAN) in the corn earworm moth Helicoverpa (= Heliothis) zea. An isolated pheromone gland bioassay showed that synthetic PBAN was active at 0.02 pmol, with maximal activity occurring at 0.5 pmol and 60 min of incubation. Second-messenger studies demonstrated that extracellular Ca2+ is necessary for PBAN activity on isolated pheromone glands. The Ca2+ ionophore A23187 stimulated pheromone biosynthesis alone, whereas the Ca2+ channel blockers La3+ and Mn2+ inhibited PBAN activity. However, the organic Ca2+ channel blockers verapamil and nifedipine did not inhibit PBAN …

Phenology Of The Western Cherry Fruit Fly (Diptera: Tephritidae) In Utah And Washington, Vincent P. Jones, Diane G. Alston, Jay F. Brunner, Donald W. Davis, Mark D. Shelton

Office of the Dean (CAFES) Scholarship

The flight period of the western cherry fruit fly, Rhagoletis indifferens Curran, was investigated in Utah tart cherry, Prunus cerasus L., orchards from 1983 to 1989 and in Washington sweet cherry, Prunus avium L., orchards between 1982 and 1988. In Utah, flies were first detected on 31 May 1989, but the average time of first detection was 9 June across nine site-years. In Washington, the first fly was detected on 23 May 1988, with an average first detection time of 1 June in the three site-years. On a degree-day (DD) scale (lower threshold of 5°C and no upper threshold), detection …

Tb147: Simulating The Development Of Mexican Bean Beetle Immature Stages, Epilachna Varivestis Mulsant (Coleoptera: Coccinellidae), On Dry Beans, Yuqing Fan, Francis A. Drummond, Eleanor Groden

Technical Bulletins

A computer model was developed to simulate and predict the phenology of Mexican bean beetle (MBB), Epilachna varivestis Mulsant, populations on dry beans, Phaseolus vulgaris. Time-varying distributed developmental rates of the egg, four larval instars, and pupal stages were simulated with degree day models, based on a standardized cumulative probability distribution function from a range of constant temperature experiments. Predictions from the simulation model provided a good fit to the observed constant temperature data and field experiments. Using temperature data in the form of daily maximums and minimums, the model can be used to predict the occurrence of immature MBB …

A Revision Of The World Amphibulus Kriechbaumer (Hymenoptera: Ichneumonidae, Phygadeuontinae), John C. Luhman

Insecta Mundi

Amphibulus Kriechbaumer (Hymenoptera: Ichneumonidae, Phygadeuontinae = Gelinae, Gelini) is revised world-wide. It is separated from its sister group genus Endasys Foerster by means of a key and a diagnosis. Keys are given to 3 speciesgroups and 25 species, including European gracilis Kriechbaumer and fennicus Sawoniewicz. Mexican satageus (Cresson) is redescribed, and 22 species are newly described: africanus, awanticeps, aurarius, aureolus, bicolor, borealis, carinarum, dentatus, duodentatus, eurystomatus, flavipes, latioris, nigripes, orientalis, pentatylus, pilosus, pseudopustulae, pustulae, pyrrhoborealis, rugosus, salicis, and tetratylus. Thirty figures illustrate diagnostic characters.

The Genus Vaejovis In Sonora, Mexico (Scorpiones, Vaejovidae), W. David Sissom

Insecta Mundi

The genus Vaejovis C. L. Koch in the Mexican state of Sonora is reviewed, based on the examination of numerous specimens from United States collections. Four species are reported to occur there: Vaejovis spinigerus (Wood), V. confusus Stahnke, V. sonorae Williams, and V. decipiens Hoffmann. Distributional information for all four species is updated, and a key is provided to facilitate identification. The subspecies V. spinigerus sonorensis Hoffmann is synonymized with V. spinigerus. The record for V. gravicaudus Williams on Isla Tiburon (Williams 1980) is demonstrated to be a misidentification resulting from atypical variation in the closely related V. spinigerus …

Notes On Ant Larvae 1989-1991, George C. Wheeler, Jeanette Wheeler

Insecta Mundi

In 1976 we published "Ant Larvae: Review and Synthesis," which we regarded as a summary of our life-time of research. During the following years so many new larvae were added to our collection and so much was published about ant larvae that we decided another general treatment was desirable; so in 1986 we published a "Ten-Year Supplement" to include additions and revisions to our Memoir. In 1987 and 1988 additional material warranted a supplement to the "l0-year Supplement" in 1989a. This article is the third supplement to the Memoir.

In the supplement, two genera are characterized, one generic characterization is …

Two new species of Muesebeckiini, Ichneutinae, are described as a new genus characterized by exodont mandibles and by alternate pairs of abdominal spiracles missing. Most specimens have been found in northern Florida and a few in eastern Texas.

Rediscovery Of Romulus Globosus Knull (Coleoptera: Cerambycidae), M. C. Thomas

Insecta Mundi

One of the rarest U.S. cerambycids, Romulus globosus, was described by Knull in 1948 based on four specimens collected in peninsular Florida. No new records have been reported in the literature since. Linsley (1963) apparently saw no specimens, since he merely quoted the original description, and gave the distribution as "Southern Florida."

The Buprestidae (Coleoptera) Of Missouri, Ted C. Macrae

Insecta Mundi

The distribution and seasonal occurrence of Missouri buprestids are discussed. Keys are presented for the eight subfamilies, 16 tribes, 23 genera, and 131 described species and subspecies known to occur in the state. Three additional species previously recorded from Missouri are excluded. Distribution within the state is cited by counties. Information on collecting techniques, seasonal abundance, and adult and larval host associations is presented and discussed.

On The Nomenclature And Classification Of The Meloidae (Coleoptera), Richard B. Selander

Insecta Mundi

Forty-three available family-group names (and three unavailable names) in Meloidae are listed as a basis for establishing nomenclatural priority. Available genus-group names, 256 in number, are listed alphabetically with indication of the type species of each; this is followed by a list of 23 names proposed or used at the genus-group level that are unavailable in zoological nomenclature. Finally, a classification of the family Meloidae to the subgeneric level is presented in which names at the family-group and genus-group levels are treated in a manner consistent with the provisions of the International Code of Zoological Nomenclature. This classification recognizes three …
