A Taxonomic Survey Of The Family Gyrinidae (Coleoptera) Of The State Of Virginia, Jerrold R. Harris

Biological Sciences Theses & Dissertations

The aquatic insect fanua of Virginia is not very well known. This is especially true of the order Coleoptera. There are few taxonomic studies on the families of Coleoptera found within the state, and one of the least known is the family Gyrinidae. It is the intent of this study to determine what species of Gyrinidae are found within the state and where they are found. Collections of the beetles were made throughout the state from March to December.

Twenty-one species of Gyrinidae were identified in Virginia, nine species of Dineutus and 12 species of Gyrinus. The family is distributed …

Plant Age Effect On The Level Of Resistance Of Rice “Ir36” To The Green Leafhopper, Nephotettix Virescens (Distant) And Rice Tungro Virus, H. R. Rapusas, E. A. Heinrichs

Department of Entomology: Faculty Publications

Plant age of a moderately resistant rice cultivar, “IR36,” had a distinct effect on the level of Nephotettix virescens (Distant) resistance. Plants at 10 d after sowing (DAS) were preferred over those at 20, 40, or 60 DAS. N. virescens survival, growth index, and adult weight were higher on plants 20 DAS than on plants 40, 60, or 80 DAS. Although the total amount of honeydew excreted was similar for “IR36” plants of all ages, the reaction of honeydew on filter paper treated with bromocresol green indicated that feeding in the nutrient-rich phloem was highest on the younger plants. Tungro …

Broadacre Pest Control After Ddt, P J. Michael

Journal of the Department of Agriculture, Western Australia, Series 4

DDT may no longer be applied to broadacre crops grown in Western Australia. It is being replaced by other more effective chemicals and with new methods of pest control. DDT was the most effective chemical for the control of several major broadacre pests in this State and farmers may well wonder why this change was necessary and how they will manage without DDT.

A Recapitulation Of The Genetics And Evolution Of Insect Biotypes On Cereals: The Case Study Of The Hessian Fly, C. Kudagamade, John E. Foster, Jaime E. Araya

Department of Entomology: Faculty Publications

The host-specific nature of the Hessian fly, Mayetiola destructor (Say) and its genetic interaction with the wheat (Triticum aestivum L. em. Thell) plant results in the evolution of virulent biotypes. However, carefully planned deployment of resistant genes can delay the evolution of biotypes and maximize the stability of resistant genes. The usefulness of the Hessian fly-wheat interaction model in breeding for insect resistance in rice is discussed.

First Report Of A Parasitic Fly From A Red Imported Fire Ant Alate Female, Daniel P. Wojcik, D. P. Jouvenaz, C. S. Lofgren

Entomology Papers from Other Sources

A number of phorid flies are known to parasitize various life stages of bees and wasps, including reproductives (Kistner 1982). Several genera of phorids are known or assumed to be parasitic on worker ants but not on reproductives (Borgmeier 1963; Borgmeier and Prado 1975). Williams (1980) summarized the known data on phorids attacking and parasitizing fire ants sens. str., Solenopsis (Solenopsis) spp., in South America. To date, only one species is definitely known to parasitize fire ant workers, although other species are assumed to be parasitic on fire ants (Williams 1980). None of these species are present in the …

A Review Of Perlinella Banks (Plecoptera: Perlidae), Boris C. Kondratieff, Ralph F. Kirchner, Kenneth W. Stewart

Entomology Papers from Other Sources

The Nearctic stonefly genus Perlinella Banks is reviewed; three valid species are recognized. Perlinella drymo (Newman) and Perlinella ephyre (Newman) are widespread east of the Rocky Mountains, whereas Perlin ella zwicki, n. sp. (P. jumipennis of Zwick 1971), is restricted to the southeastern Coastal Plain. Perlinella jumipennis (Walsh) is replaced as a synonym of Perlinella ephyre. Keys for adults and nymphs are provided, and the nymph of P. zwicki is described for the first time. Male drumming calls of Perlin della drymo and Perlinella ephyre are described.

Sheep Lice : Prospects For Eradication, F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

Sheep biting lice have been controlled over the past 86 years in Western australia by a combination of routine insecticidal treatment after shearing and action by the department of Agriculture officers under legislation.

In July 1987 the sheep industry and the State Government will implement a plan to eradicate lice from sheep flocks in the agricultural areas and eventually in the pastoral areas. To achieve this the co-operation of many sectors of the industry will be required. Assuming co-operation is forthcoming, it is possible that by 1996 wool from agricultural areas will be free of lice and insecticidal treatment form …

Some Potential Evolutionary Costs Associated With Paternal Care In The Water Bug Belostoma Flumineum Say, Larry Johnson

Masters Theses

Female water bugs (Belostoma flumineum) deposit eggs in a mucilaginous cement on the back of conspecific males, who then brood these eggs until hatching. Sex role reversal, in which females compete for males and males are discriminating, is predicted in this species because males provide parental care exclusively, and represent a limited resource. Presumably the advantage of this paternal behavior is increased survival of young. However, the potential exists for this egg-brooding behavior to incur evolutionary costs, and quantifying some of these costs was the thrust of this study.

One cost, a loss of polygynous opportunity, was investigated …

Comparison Of Gelled And Meat Diets For Rearing Screwworm, Cochliomyia Hominivorax (Diptera: Calliphoridae), Larvae, David B. Taylor, Robert L. Mangan

Department of Entomology: Faculty Publications

A liquid diet solidified with an acrylamide-acrylate polymer gelling agent (Water-Lock) was compared with a standard meat diet for rearing screwworm, Cochliomyia hominivorax (Coquerel), larvae. Size and yield of larvae reared on gel diet were equal to, or greater than, those of larvae reared on meat diet. Duration of larval development was increased by ca. 13 h on gel diet; however, variability of pupal weight and larval survival over generations were reduced when gel diet was used. Larval size was also more uniform over the 3-d period when larvae leave the rearing medium to pupate (crawl-off). Gelled diet was more …

Host Plants (Except Rice) Of The Rice Leaffolder Cnaphalocrocis Medinalis Geunee Reported In Literatures (1907·1983), R. C. Joshi, T. Wada, E. A. Heinrichs

Department of Entomology: Faculty Publications

The complex of rice leaffolder species, Cnaphalocrocis medinalis Guenee and Mararmia parnalis Bradley, hitheto considered as pests of minor importance, was observed by authors to cause severe damage to rice at the International Rice Research Institute, Philippines during 1983-84. It is significant to note that the damage symptoms for all leaffolder species are similar. In the past, the majority of the host plants reported for C. medinalis are based on field observation only (Table 1). Without rearing studies and subsequent taxonomic confinnation, it is possible that some of these records are due to the other less well-known leaffolders, …

Soil Applications Of Steinernematid And Heterorhabditid Nematodes For Control Of Colorado Potato Beetles, Leptinotarsa Decemlineata (Say), Robert J. Wright, Fernando Agudelo-Silva, Ramon Georgis

Department of Entomology: Faculty Publications

Three strains of Steinernema feltiae Filipjev (All, Mexican, and Breton strains) and one of Heterorhabditis heliothidis (Khan, Brooks, and Hirschmann) were evaluated for their potential to control Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), larvae and pupae in the soil. In laboratory studies, H. heliothidis and S. feltiae (Mexican strain) produced the highest mortality (6 days posttreatment) of CPB when applied to the surface of a soil column containing mature CPB larvae 5 cm below. Mortality ranged from 80 to 90% at rates of 79-158 nematodes/cm². Similar results were seen in a field microplot study with all four …

A Study Of The Biology Of Rhopalosiphum Padi (Homoptera: Aphididae) In Winter Wheat In Northwestern Indiana, J. E. Araya, John E. Foster, S. E. Cambron

Department of Entomology: Faculty Publications

Periodic collections of the bird cherry-oat aphid, Rhopalosiphum padi, during two years revealed small populations on winter wheat in Lafayette, Indiana. The greatest numbers were found on volunteer wheat plants before planting. In the autumn, aphids were detected on one-shoot plants by mid-October and also early March. The populations remained small until mid-June. We conclude that the aphid feeding did not significantly affect the plants, but helped spread barley yellow dwarf virus.

Effects Of Barley Yellow Dwarf Virus On The Biology Of The Bird Cherry-Oat Aphid, Rhopalosiphum Padi (L.), J. E. Araya, John E. Foster

Department of Entomology: Faculty Publications

Diverse parameters of the life cycle of Rhopalosiphum padi (L.), maintained on leaf sections of healthy or BYDV (PA V strain)·infected wheat and oat plants, were compared in the laboratory at 18 ± 1 C. The aphids reared on infected ",heat leaf sections had a shorter lifespan and adult Jife (P<= 0.05) than on uninfected wbeat (23.7 and 27.5 days for lifespan, and 17.9 and 21.4 days for adult life, respectively). Tbe BYDV-infection on wheat (cvs. 'Abe' and 'Caldwell') increased (P<= 0.05) the reproductive ability of the aphid from 73.9 to 78.1 nymphs per female (5.9 to 6.5 nymphs per day during the reproductive period). No significant dilTerences were detected when using oa15 (cvs. 'ClintIand 64' and 'Porter').

Aphid Feeding Behavior: Relationship To Barley Yellow Dwarf Virus Resistance In Agropyron Species, Richard H. Shukle, David J. Lampe, Richard M. Lister, John E. Foster

Department of Entomology: Faculty Publications

The infectibility of various Agropyron species (wheatgrasses) was examined with respect to three isotates of barley yellow dwarf virus (BYDV) by infesting them with appropriate vector aphids, followed by testing by enzyme-linked immunosorbent assay. Feeding behavior of the vetors Rhopalosiphum padi and Sitobion avenae was also electronically monitored to determine their ability to inoculate phloem. The results indicated that resistance to BYDV infection occurs in several Agropyron species. For most species tested. resistance seemed due to failure in virus increase. but in some species a major constraint on infection \\'as the inability of vectors to locate phloem. Two potential approaches …

Natural Enemies Of Rice Leaf Folder Cnaphalocrocis Medinalis (Guenée) —A Critical Review, R. C. Joshi, E. P. Cadapan, Elvis A. Heinrichs

Department of Entomology: Faculty Publications

A chronological review of the biological control agents of rice leaf folder, Cnaphafalocrocis medinalis Guenée, including the stage of host attacked in different countries, their activity and suggestions for future.

The rice leaf folder, Cnaphalocrocis medinalis Guenée, which was a pest of minor importance till the last decade, recently has assumed major importance in many rice ecosystem of Asia, the South Pacific Islands, Hawaii and Australia (Hirao, 1982). Increasingly frequent outbreaks of this pest (Table I) in recent years have been attributed to the introduction of modern rice technologies, namely: Continuous and overlapping cropping (Rajamma and Das, 1969); introduction of …

Attraction Of The Stem Borer Chilo Partellus (Swinhoe) Larvae (Lepidoptera: Pyralidae) By Certain Coloured Surfaces For Trapping, Kailash Narain Saxena, Jeremiah Dickens Onyango

All Peer-Reviewed Publications

Different colour papers have been shown to attract the first and third instar larvae of Chilo partellus in different degrees. Green bice (No. 329) and light green (No. 323) elicited maximum larval attraction; followed by foliage green (No. 328) and cadmium yellow (No. 307). The green bice paper has been found to be much more effective than foliage green or cadmium yellow paper as a cylindrical sticky trap for the larvae. Even when competing with the host plant, sorghum, these colour paper traps proved more effective than the plants for attracting and trapping the larvae. © 1987, JAPANESE SOCIETY OF …

A Revision Of The Genus Brachycoryna (Coleoptera: Chrysomelidae: Hispinae), C. L. Staines Jr.

Insecta Mundi

The generic name Brachycoryna was first published by Guerin-Meneville (1844) who at that time also described B. pumila which was the only included species (type species by monotypy). The locality data given by Guerin's material is "Carthagene" (Cartagena, Columbia). Guerin correctly receives authorship of Brachycoryna since a single .combined description of a new genus and new species published before 1930 is considered an "indication" for each name (Intern. Code 2001. Nomen., Article 12). Some authors (Weise, 1911 a,b; Papp, 1953) had assigned authorship to Baly (1885) who published the first generic description and reported B. pumila from Mexico, Guatemala, and …

Supplement I To E. C. Zimmerman, “Insects Of Hawaii” Vol. 7 (1958) Macrolepidoptera, J. C. E. Riotte

Insecta Mundi

This supplement concerns species of the family Sphingidae (pages 425-444) introduced to Hawaii since 1958 and now firmly established. The introductions are connected with the rapid growth of air traffic between Hawaii and SE Asia since the mid-1970s. Of special interest is the fast interisland colonization as reported in the HAWAII COOPERATIVE ECONOMIC INSECT REPORT (HCEIR), published by the State Department of Agriculture, Honolulu, HI until 1980, subsequently called HAWAII PEST REPORT.

A North Florida Ant Fauna (Hymenoptera: Formicidae), Clifford Johnson

Insecta Mundi

This paper updates and summarizes the ant fauna of Alachua County, Florida, with two basic objectives. The first objective is presentation of a current, documented check-list consistent with existing taxonomy and an insight on species groups where taxonomic changes are likely in subsequent revisions. The second objection objective seeks to identify changes in the fauna since Van Pelt’s pioneer survey of 1948, and provide a basis for similar comparisons in the future.

The county consists of 902 square miles in north-central Florida and embraces essentially all inland habitats of the northern peninsula. This rich habitat variability is reflected in its …

Diplocentrus Colwelli, A New Species Of Scorpion From Northern Mexico (Diplocentridae), W. David Sissom

Insecta Mundi

Presently, only a single species of the genus Diplocentrus is known from northeastern Mexico, D. whitei (Gervais) (Hoffman 1931 ). This species is dark brown to black and is quite large, with adults 65-75 mm long. Recent collecting in the mountains near Monterrey and El Potosi, Nuevo Leon, Mexico has revealed the presence of a much smaller, more lightly-colored species. The description of this new species is the subject of the present paper.

Nomenclature and mensuration essentially follows that of Stahnke (1970), with the following exceptions: carinal terminology and cheliceral measurements are after Francke (1975, 1977) and trichobothrial terminology is …

Bibliography Of The World Literature Of The Bethylidae (Hymenoptera: Bethyloidea), Bradford A. Hawkins, Gordon Gordh

Insecta Mundi

The Bethylidae are a primitive family of aculeate Hymenoptera which presently consists of about 2,200 nominal species. They are worldwide in distribution and all species are primary, external parasites of Lepidoptera and Coleoptera larvae. Due t o their host associations, bethylids are potentially useful for the biological control of various agricultural pests in the aforementioned groups. Unfortunately, the true potential of bethylids in applied biological control cannot be ascertained now because they have been used infrequently. Some species show strong promise, but t h e i r use is handicapped by a relative lack of basic taxonomic and biological knowledge. …
