A Preliminary Checklist Of The Hydrophiloidea (Coleoptera) Of Maryland, C. L. Staines Jr.

Insecta Mundi

The only lists of Hydrophiloidae (Coleoptera: Hydrophilidae, Helophoridae, Hydrochidae, and Hydraenidae) from the mid-Atlantic region are Ulke (1902) who reported 46 species from the District of Columbia and Matta (1974) who presented keys and short descriptions for the 49 aquatic species of Hydrophilidae of Virginia.

The following checklist records 103 species (75 aquatic) from Maryland. Comparable lists of aquatic species for other states are as follows: 53 species recorded from Florida by Young (1954); 20 species recorded from Ithaca, New York by Swenson (1982); 67 species from North and South Carolina by Brigham (1982); and 47 species from Illinois by …

Stings Of Ants Of The Tribe Pheidologetini (Myrmicinae), Charles Kugler

Insecta Mundi

The definition of the Tribe Pheidologetini in the ant subfamily Myrmicinae has always been problematic. Emery (1922) erected the tribe to contain the genera Pheidologeton, Oligomyrmex, Aneleus, Lophomyrmex, Trigonogaster, Ekebomyrma, Carebara and Paedalgus, but Wheeler (1922) put all these genera in the Solenopsidini. Neither Emery nor Wheeler satisfactorily defined either tribe. More recently, Ettershank (1966) proposed the “Pheidologeton genus group” composed of Pheidologeton, Oligomyrmex (including most Aneleus) , Lophomyrmex, Carebara, Paedalgus and Anisopheidole, but still uncertainty remains as to relationships of these genera and even the definitions of the genera themselves. New characters and new means of analysis are needed …

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. …

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 …

Anzora And Dworena, Two New Genera Erected For Australian Species Formerly Placed In Paratella And Sephena. (Homoptera: Fulgoridae), John T. Medler

Insecta Mundi

The genera Paratella and Sephena were established by Melichar (1902) for complexes of species having distribution principally in New Guinea. However, three of Melichar’s new species of Paratella, i.e., fumaria, fusconigra and modesta, were known only from localities in Australia and/or New Zealand. Kirkaldy (1906) described Sephena argue, cinerea and rubida from specimens collected in Australia. He commented that they had the appearance of Paratella while having the characters of Sephena assigned by Melichar.

Melichar (1923) and Metcalf (1957) each retained the above named species in Paratella and Sephena The type specimens of the species named above were examined in …

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.

Rearing Blister Beetles (Coleoptera, Meloidae), Richard B. Selander

Insecta Mundi

The receipt, recently, of several requests for information and assistance in rearing blister beetles (Meloidae) has prompted me to prepare the following account of the rearing method used in my laboratory. In order to make the account as useful as possible to new students. I have included a considerable amount of information on meloid bionomics. Larval phases are designated as triungulin (TI, first grub (FG), coarctate (C), and second grub (SG). Where necessary, instar is indicated by a numerical subscript. The pupa and adult are symbolized by P and A, respectively. 1 assume that the reader has some knowledge of …

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 …

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 …

Temporal Constancy In Grasshopper Assemblies (Orthoptera: Acrididae), Anthony Joern, Kenneth P. Pruess

Department of Entomology: Faculty Publications

1. Temporal constancy in the structure of grasshopper assemblies (about forty-five species each) from two types of North American grasslands was assessed; one site was followed 25 years and the other 7 years.

2. Densities and relative abundances varied but composition of assemblies based on ranks suggested significant structure when three or more species were included in the analysis.

3. Results compared favorably with other insect herbivore assemblies which have been examined; variability in population change was intermediate along the spectrum of organisms which have been studied.

Technical Bulletins

This study was initiated to provide Christmas tree growers with a selection of insecticides capable of effective control of balsam twig aphid (Mindarus abietinus Koch) on balsam fir. Low rates of active ingredients were tested to assure minimal environmental impact and reduced chemical costs

Tb123: Experimental Application Of B.T.I. For Larval Black Fly Control: Persistance And Downstream Carry, Efficacy, Impact On Non-Target Invertebrates And Fish Feeding, K. Elizabeth Gibbs, Francis C. Brautigam, Constance S. Stubbs, Larry M. Zibilske

Technical Bulletins

In the summer of 1985 a field experiment was conducted in the Sugarloaf area of Maine on the use of B.t.i. to reduce the numbers of black fly larvae in the Carrabassett River and a tributary stream. The objectives were to determine the rate of application necessary to produce an acceptable reduction in black fly larvae, to study the fate and persistence of B.t.i. in a stream following application, to determine the impact of B.t.i. on the abundance and drift of non-target stream insects and on the feeding success and diet composition of fishes in the treated streams.

Son varias las especies presentes en la Argentina, Uruguay y Chile, pero por el momento vamos a referirnosala fauna de este último país. Debemos aclarar que no consideramos aquí las especies correspondientes a Sphictostethus Kohl, que han sido tratadas como Priocnemis por algunos autores, ya que constituye un género bien …

Taxonomy Of The Adults Of The Genus Strauzia Robineau-Desvoidy(Diptera, Tephritidae), G. C. Steyskal

Insecta Mundi

The recently increased importance of sunflowers (Helianthus annuus Linnaeus) as a crop has brought with it an increased interest in the sunflower maggot, a long-recognized common name for Strauzia longipennis (Wiedemann). The larva of this species bores downward in the stem and feeds upon the pith of sunflowers. Until recently the genus Strauzia was considered to include only the type-species S. longipennis, with 7 varieties (Foote, 1965). It is now known that some of these varieties should be classed as distinct species, differing morphologically and biologically.

Praestochrysis Of The Ethiopian Region With A Key And Descriptions Of New Species(Hymenoptera: Chrysididae), R. M. Bohart

Insecta Mundi

Praestochrysis Linsenmaier contains those species of Chrysidinae with five teeth on the posterior margin of tergum III, first flagellomere (F-I) less than 3 times as long as broad (often much shorter), and clypeal length below antennal sockets (subantennal distance) not more than diameter of the midocellus (MOD). The genus is widespread in the Old World, but a majority of the known species are in the Ethiopian Region. Host records are rather few, but it is likely that nearly all species attack moth larvae and emerge from their cocoons. Praestochrysis shanghaiensis (F. Smith) is a well known parasitoid of the silk …

Lithoserix Williamsi (Siricidae: Hymenoptera) A Newly Recognized Fossil Horntail From Florissant, Colorado, F. Martin Brown

Insecta Mundi

A recently found fossil from the old Scudder pit (?) appears to be a large female horntail. It shows the ventral aspect. Compared with modern Siricidae, the length of its ovipositor in relation to the body proper suggests modern Xeris spectrum. Unfortunately the venation is incompletely preserved on both wings. In addition to this the forewings and hindwings overlap to some extent on each side. What venation is decipherable is seen in the two sketches. It does not seem to agree with any of the modern genera examined but approaches that of Sirex more closely than any other. Both …

Allotype Description Of The Male Scale Sclerococcus Chilensis (Homoptera: Coccoidea: Asterolecaniidae), P. L. Lambdin

Insecta Mundi

Descriptions of species in the genus Sclerosococcus are primarily based on the female morphology (McKenzie 1958, Lambdin 1980). The lack of descriptions for males is attributed to their brief seasonal appearances (lasting only a few hours) and their small size that makes collection of adult specimens difficult. As a result, adequate descriptions for only a few males of Asterolecaniidae are available for comparisons. Of those species where males are known, most descriptions are of the tests or general morphological aspects (Russell, 1941). The most comprehensive descriptions for adult males in the family were provided for Asterolecanium proteae (Giliomee 1968) and …

Revision Of The Nearctic Glyphicnemis Foerster (Hymenoptera: Ichneumonidae, Gelinae), John Luhman

Insecta Mundi

GLYPHICNEMIS Foerster is a small Holarctic genus in the subtribe Endaseina of the Gelini. Nearctic species were placed in PHYGADEUON Gravenhorst until Townes (1944) placed them in the subgenus GLYPHICNEMIS within ENDASYS Foerster . However, earlier Cushman (1925) had transferred PHYGADEUON CRASSIPES Provancher, a junior synonym of G. MANDIBULARIS (Cresson), to GLYPHICNEMIS, and the Palearctic species, at first placed in PHYGADEUON, were included by Habermehl (1916) i n GLYPHICNEMIS, reduced t o a subgenus within STYLOCRYPTUS Thomson (1873). This status was continued until Townes (1970) listed and described GLYPHICNEMIS as a seperate genus.

A New Thecline From Sulawesi (Lepidoptera: Lycaenidae: Theclinae), Lee D. Miller, Jaqueline Y. Miller

Insecta Mundi

A number of years ago we received a large lot of material collected by Robert G. and Clo M. Wind during their 1939-1940 expedition to the “East Indies” and published on the Danaidae and Satyridae of that trip (L. and J. Miller, 1978). One of the insects that the Winds considered to be of special significance was a male of a thecline that Bob Wind had intended to describe for his then wife. Both Bob and Clo asked us to describe the butterfly, but before we had an opportunity to describe the insect both Bob and Clo died. We now …

The Systematics And Biology Of The Flea Beetle Genus Crepidodera Chevrolat (Coleoptera: Chrysomelidae) In America North Of Mexico, Richard H. Parry

Insecta Mundi

Crepidodera Chevrolat is a genus of small metallic-colored flea beetles belonging to the family Chrysomelidae. Although these insects are quite common in the field and numerous in museum collections, the members of the genus in North America are, until now, poorly known. Heikertinger (1948-1950) recognized 4 taxa and recently, Lazorko (1974) described 3 additional species. These 7 species were recognized primarily on the basis of genital differences and were otherwise difficult to identify.

Examination of a large accumulation of museum material and investigations in the field have indicated the presence of several additional species in the North American fauna. A …

A Preliminary Checklist Of The Hydradephaga (Coleoptera) Of Maryland, C. L. Staines Jr.

Insecta Mundi

The only published checklist of the Hydradephaga from the Maryland area is Ulke (1902) who records 65 species from the District of Columbia. The present paper lists 121 species as occurring in Maryland. Comparable lists for other states are as follows: Young (1954), 120 species from Florida; Folkerts (1978), 120 species from New York; and Brigham (1982) and Sanderson (1982), 115 species from North and South Carolina. Some of the identifications are questionable until generic revisions are completed. This is especially true of Hydroporus and Gyrinus.

Description Of The Larvae Of Two Species Of Hemipeplus Latreille (Coleoptera:Mycteridae), M. C. Thomas, R. E. Woodruff

Insecta Mundi

The key description and illustrations of mouthparts, ocelli, and terminal abdominal segments by Bovinq & Craighead (1931) have been the only information on the larval stages of the genus Hemipeplus Latreille, except for the observation by van Emden (1942) that individuals of the genus would not key properly in Boving & Craighead's key. Their example was of an undescribed species from Cuba. The semidiagrammatic illustrations make it difficult to identify the species illustrated, although it may be H. marginipennis (LeConte).

This paper is based on larvae collected by the authors, in each case associated with adults.

Laying-Worker Production Of Drones In Mixed Colonies Of Africanized And European Honey Bees (Hymenoptera: Apidae), Richard L. Hellmich Ii, Robert G. Danka, Anita M. Collins, Thomas E. Rinderer

Richard L Hellmich

Queenless honey-bee colonies (Apis mellifera L.) with mixed populations of Africanized and European workers produced 15-fold more Africanized drones than European drones. Drones developed from eggs laid by previously nonreproductive workers. First eclosion of Africanized drones preceded that of European drones by 2.4 days. Laying workers of both bee types developed more rapidly when colonies had Africanized queens and brood before queenlessness than when colonies had European queens and brood. The percentage of European drones of the total number of drones that eclosed each day changed significantly in a curvilinear manner over 15 days, starting near 0, increasing to a …

Insects And Pathogens Associated With Rice Grain Discoloration And Their Relationship In The Philippines, S. C. Lee, M. E. Alvenda, J. M. Bonman, Elvis A. Heinrichs

Department of Entomology: Faculty Publications

Species of pathogens and insects associated with grain discoloration in the Philippines were identified. Leptocorisa oratorius was the most dominant insect species causing discoloration. Pathogenicity tests of fungal organisms isolated from discolored grains showed that Drechslera oryzae, Curvularia lunata, Trichoconiella padwickii, Sarocladium oryzae, Alternaria tenuis, and Fusarium solani were the common pathogens responsible for "dirty panicle" disease of rice. Discoloration incidence was higher on treatment when both pests were present than when they occurred singly. The discoloration severity was attributed to the pathogens whereas rice bug caused a high decrease in grain weight and unfilled grains. Rice bug feeding on …

Patterns Of Tree Mortality During An Uncontrolled Spruce Budworm Outbreak In Baxter State Park, 1983, Akira Osawa, Charles J. Spies Iii, John B. Dimond

Technical Bulletins

A forest inventory of Baxter State Park, Maine, was done during the summer and fall of 1983 to study the patterns of mortality in balsam fir and in the red-black spruce complex during an uncontrolled spruce budworm outbreak. The volume of trees that died during the outbreak was estimated at 40% of the original quantity. Fir mortality was consistently greater than that of spruce. The percentage mortality of spruce was always greater in the higher elevation zone than in the lower elevation zone. Percentage mortality of fir and spruce showed inconsistent patterns in relation to the proportion of hardwood species …

Between Population Comparison Of Resource Acquisition In The Long Jawed Orb Weaving Spider Tetragnatha Elongata, Rosemary Grace Gillespie

Doctoral Dissertations

Behavioral adaptations for resource acquisition in the long jawed orb weaving spider Tetragnatha elongata Walckenaer (Araneae: Tetragnathidae) are documented in this study. It examines the form and mechanism of spider foraging behavior, an essential prerequisite to the realization of the commercial use of spiders in integrated pes t management. Being the most common and ubiquitous of insect predators, spiders offer tremendous potential as stabilizers in agro ecosystems with unstable cycling of phytophagous insects. The initial part of this study examines the mechanisms employed by T. elongata in selecting a habitat, and demonstrates that spiders do not build webs where the …
