In Vitro Enzymatic Chlorophyll Catabolism In Wheat Elicited By Cereal Aphid Feeding, Xinzhi Ni, Sharron S. Quisenberry, John P. Markwell, Tiffany Heng-Moss, Leon G. Higley, Frederick P. Baxendale, Gautam Sarath, Robert Klucas

Department of Entomology: Faculty Publications

Chlorophyll degradation is a complex phenomenon that often accompanies insect feeding damage to plants. Loss of chlorophyll can be initiated by several reactions, including oxidative bleaching, chlorophyllase activity, and Mg-dechelatase activity. Extracts from the Russian wheat aphid [Diuraphis noxia (Mordvilko)], the bird cherry-oat aphid [Rhopalosiphum padi (L.)], and aphid-infested and uninfested wheat plants were assayed in vitro for activities involved in chlorophyll degradation. Although the initial infestation was the same (10 apterous adults) for both aphid species, D. noxia weight was significantly higher than R. padi after feeding for 12 days. Consequently, D. noxia feeding caused greater fresh …

Cryopreservation Of Embryos Of The New World Screwworm Cochliomyia Hominivorax (Diptera: Calliphoridae), R.A. Leopold, W.B. Wang, Dennis Berkebile, T.P. Freeman

Department of Entomology: Faculty Publications

A method for cryopreserving embryos of the screwworm, Cochliomyia hominivorax (Coquerel), was developed for the long-term storage of strains used in research projects and for colonies maintained as back-up to production strains that are mass-reared for sterile insect release programs. This protocol, when combined with a previous procedure that was designed to render screwworm embryos permeable to water loss and the influx of cryoprotectants, yields rates of ~53% hatching, 22% pupation, and 75% adult emergence. These yields are all lower than control levels, but by the next generation the progeny of the cryopreserved flies are near or equal to control …

A Review Of The Neotropical Genus Neocorvicoana Ratcliffe And Micó, New Genus (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini), Brett C. Ratcliffe, Estefanía Micó

University of Nebraska State Museum: Entomology Papers

The southern Neotropical cetoniine genus Neocorvicoana Ratcliffe and Micó new genus (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini) is established for three species previously placed in Corvicoana Strand, 1934 (nomen nudum) and Gymnetis MacLeay, 1819: N. chalybea (Kirby), N. reticulata (Schürhoff), and N. tricolor (Schürhoff), new combinations. The type species of the new genus is N. reticulata (Kirby). Corvicoana rudolfi (Frölich) is transferred to the genus Gymnetis. Corvicoana suavis (Schürhoff) and C. castanea (Schürhoff) are junior synonyms of N. chalybea. We include a taxonomic key to the species, nomenclatural history, descriptions, illustrations, and commentary.

New Dung Beetle (Coleoptera: Scarabaeidae) Records For Florida, David Almquist

Insecta Mundi

Euoniticellus intermedius (Reiche) was released by the USDA for the purpose of dung removal and control of pestiferous dung-breeding flies in Texas, California, and Georgia around 1978-1979, although it did not become established in Georgia at that time (Blume 1984; Fincher 1986; Montes and Halffter 1998). Apparently, it has not been officially recorded outside of Arizona, California, and Texas in the contiguous U.S., although Montes and Halffter (1998) did a detailed study of its migration into Mexico.

Schizaphis Minuta (Van Der Goot) (Homoptera: Aphididae), New To The United States, Susan E. Halbert, Kenneth L. Hibbard, David J. Voegtlin

Insecta Mundi

Schizaphis minuta (van der Goot) (Fig. 1) was found for the first time in the Western Hemisphere in suction trap samples in Florida. The first specimen was collected in a trap at Quincy (Gadsden County) for the period 16 - 23 November 1998. The record subsequently was verified by collections on several species of Cyperus in the Ft. Pierce area. The aphid is specific to Cyperus and is unlikely to pose any threat to agriculture. Schizaphis minuta probably is native to Asia and has been recorded previously in Africa and Australia. It is not known to be a pest.

New Species And Records Of Rhyssa And Rhyssella (Hymenoptera: Ichneumonidae: Rhyssinae) From Florida And Central America, Charles C. Porter

Insecta Mundi

Abstract: Rhyssa neotropicae n. sp. is the first Rhyssa to be recorded from the New World tropics, where it was collected in cloud forest at 1800 m on Monte Uyuca near Zamorano, Honduras. It is closely related to the Nearctic R. hoferi Rohwer and R. howdenorurn Townes but differs from all other Rhyssa by its complexly yellow and black marked head and body, whose color pattern mimics that of aggressive social vespid wasps (Agelaia) which occur in the same habitat. Rhyssa howdenorurn Townes is recorded for the first time from Florida and Oklahoma. The genus Rhyssella, previously …

First Records Of The Neotropic Genus Dilopharius Townes (Hymenoptera: Ichneumonidae: Ichneumoninae) In Florida, Charles C. Porter

Insecta Mundi

Dilopharius Townes (1966) ranges from the southern United States to Argentina. Its only described species is D. otomitus (Cresson 1868), previously known from Mexico and south Texas, but now recorded for the first time from Florida.

This is a medium sized ichneumonid (fore wing 5-10 mm long) recognizable as follows: mandible broad, lower tooth a little shorter than upper; occipital carina joins base of mandible; scutellum nearly flat, with a strong, percurrent lateral carina; propodeum with broadly triangular apico-latera1 crests; female gaster short and broad; second tergite with coarse punctures, thyridia broad, space between them not much greater than width …

Small Carrion Beetles (Coleoptera: Leiodidae: Cholevinae) From Burrows Of Geomys And Thomomys Pocket Gophers (Rodentia: Geomyidae) In The United States, Stewart B. Peck, Paul E. Skelley

Insecta Mundi

The cholevine beetles inhabiting burrows of Geomys and Thomomys pocket gophers (Rodentia: Geomyidae) are reviewed. Catops geomysi n. sp. and Ptomaphagus geomysi n. sp. are described. Both of these species and Ptomaphagus schwarzi Hatch appear to be regular and obligate inhabitants of Geomys burrows but are not host specific. Nemadus hornii Hatch, Sciodrepoides ruatsoni hornianus (Blanchard), Catops simplex Say, Ptomaphagus cavernicola Schwarz, Ptomaphagus consobrinus (LeConte), Ptomaphagus fisus Horn, and Ptomaphagus texanus Horn were less frequently collected and are probably facultative inhabitants of Geomys burrows, as well as nests or dens of other small mammals. Ptomaphagus nevadicus Horn is an inhabitant …

Eicosanoids Act In Nodulation Reactions To Bacterial Infections In Newly Emerged Adult Honey Bees, Apis Mellifera, But Not In Older Foragers, Jon C. Bedick, Hasan Tunaz, A. R. Nor Aliza, Sean Putnam, Marion D. Ellis, David W. Stanley

Department of Entomology: Faculty Publications

Nodulation is the first, and qualitatively predominant, cellular defense reaction to bacterial infections in insects. We tested the hypothesis that eicosanoids also mediate nodulation reactions to bacterial challenge in adults of a social insect, the honey bee, Apis mellifera. Treating newly-emerged experimental bees with the eicosanoid biosynthesis inhibitor, dexamethasone, impaired nodulation reactions to bacterial infections, and the influence of dexamethasone was reversed by treating infected insects with arachidonic acid, an eicosanoid precursor. Several other eicosanoid biosynthesis inhibitors, including the cyclooxygenase inhibitor, indomethacin, and the dual cyclooxygenase/lipoxygenase inhibitor, phenidone, also impaired the ability of experimental honeybees to form nodules in …

An Examination Of The Mitoura (Lycaenidae) In The Southeastern United States: With The Description Of A New Subspecies Of Mitoura Hesseli, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Four subspecies of Mitoura grynea occur in the United States east of the Mississippi River. The nominate subspecies occupies this entire area except for Florida and the coastal regions of South Carolina and Georgia. Mitoura g. grynea is usually associated with Juniperus virginiana. A neotype is designated for Lycus gryneus from Aiken County, South Carolina. Mitoura grynea smilacis is endemic to the southeastern coastal islands and coastal mainland from about Brunswick Georgia north to the Santee River delta of South Carolina. Smilacis’ range corresponds to that of Juniperus silicicola in that area. A neotype is designated for …

An Examination Of Southeastern U. S. Satyrium (Lycaenidae: Theclinae), Part Two: The Identification And Delimitation Of Nominate Satyrium Liparops And The Description Of A New Subspecies From West Central Peninsular Florida, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

The name Satyrium liparops liparops has traditionally been applied to all liparops populations from eastern Georgia southward. This tradition is shown to be in error. The type locality of nominate liparops is restricted by original description to Screven County, Georgia. A neotype is designated from Screven County and deposited in the Museum of the Hemispheres (MOTH) collection Goose Creek, South Carolina. The range of nominate liparops is projected to be from coastal South Carolina across the far southern United States (including the Florida panhandle) and into Texas. The population in west central peninsular Florida is described as new subspecies S …

An Examination Of Southeastern U.S. Satyrium (Lycaenidae: Theclinae), Part One: An Obscure New Subspecies Of Satyrium Edwardsii, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Satyrium edwardsii meridionale is described as a new subspecies from Aiken County, South Carolina, United States. This scarce colony is the southeasternmost known population of this butterfly in the United States. It was discovered by the author (Ronald R. Gatrelle) in 1990 near Aiken State Park in Aiken County, South Carolina. This site is in South Carolina’s upper Coastal Plain in the southern part of the state adjacent to Georgia. It is known from only one male and one female at the type locality. Because it was known from only one pair, the author thought it best to wait until …

Descriptions Of The Larvae Of Hoplopyga Singularis (Gory And Percheron) And Hologymnetis Cinerea (Gory And Percheron) With A Revised Key To The Larvae Of New World Gymnetini (Coleoptera: Scarabaeidae: Cetoniinae), Estefanía Micó, W. Eugene Hall, Brett C. Ratcliffe

Larvae And Pupae Of New Guinea Tabanidae (Diptera). I. Species Of Chrysops Meigen, James T. Goodwin

Insecta Mundi

Information on the immature stages of Australasian Tabanidae found in published literature dealt with only 17 species, all so far known only from Australia and none representing the genus Chrysops Meigen. Two of the four Australian species of Chrysops are found on the island of New Guinea, and both, C. albicinctus Wulp and C. australis Ricardo, are described and illustrated.

Color Forms Of Monocesta Coryli (Say) In West Virginia (Coleoptera: Chrysomelidae), Shawn M. Clark

Insecta Mundi

Monocesta coryli (Say) is rather widespread in the eastern United States. In life, the beetles are usually bright yellow with the basal and apical thirds of the elytra metallic blue. In pinned specimens, the yellow areas fade to pale tan. A number of years ago (Clark, 1986), I reported on an unusual color form that occurs in southern Ohio, the dark elytral markings being either entirely absent or very poorly developed. More recently (Clark, 2000), I stated that both forms occur in West Virginia, but I gave very little information regarding the distribution of each.
