Voltinism And The Induction Of Aestival Diapause In The Colorado Potato Beetle, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae), Maurice J. Tauber, Catherine A. Tauber, John J. Obrycki, Brian Gollands, Robert J. Wright Sep 1988

Voltinism And The Induction Of Aestival Diapause In The Colorado Potato Beetle, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae), Maurice J. Tauber, Catherine A. Tauber, John J. Obrycki, Brian Gollands, Robert J. Wright

Department of Entomology: Faculty Publications

Field studies over 3 yr demonstrated that overwintering populations of the Colorado potato beetle in upstate New York and on Long Island are composed of adults from both the first and second summer generations. The two populations from the climatically different regions differ in their responses to environmental factors that influence voltinism. The critical photoperiod for aestival diapause induction is longer, and the induction of diapause by low temperature is greater, in the population from the cooler, inland locality (upstate New York) than in the population from the warm coastal area (Long Island). Under the long days of early summer, …


Use Of Radiography In Behavioral Studies Of Turfgrass-Infesting Scarab Grub Species (Coleoptera: Scarabaeidae), M. G. Villani, Robert J. Wright Sep 1988

Use Of Radiography In Behavioral Studies Of Turfgrass-Infesting Scarab Grub Species (Coleoptera: Scarabaeidae), M. G. Villani, Robert J. Wright

Department of Entomology: Faculty Publications

The behavior of turfgrass-infesting scarab grubs in response to soil physical properties may affect the stress that each species exerts on turfgrass and the efficacy of control tactics. To gain a more realistic picture of the events that occur within the soil matrix, we have developed a nondestructive X-ray technique to study soil insect movement and behavior in simulated and natural soil blocks in the laboratory Laboratory studies using this technique were done to determine the effect of some soil physical factors on scarab grub movement patterns. Species-specific differences were demonstrated in the responses of four scarab grub species (Japanese …


Focality And Mobility Of Some Peridomestic Cockroaches In Florida (Dictyoptera: Blattaria), Richard J. Brenner Jul 1988

Focality And Mobility Of Some Peridomestic Cockroaches In Florida (Dictyoptera: Blattaria), Richard J. Brenner

Entomology Papers from Other Sources

The microhabitat distribution and activities of peridomestic cockroaches were examined (August to October 1985) at three sites in northcentral Florida to assess concentration, immobility, and accessibility of populations. Smokybrown cockroaches, Periplaneta fuliginosa (Serville), and Eurycotis floridana (Walker) accounted for at least 67% of cumulative recaptures at each site. Populations were strongly concentrated in palms, trees with treeholes, woodpiles, and (to a lesser extent) various mulches; salient differences were observed for each species, indicating a partitioning of resources. Recapture rates were high, averaging >62% over all three sites for females of both species; rates were significantly lower for males (P < 0.05), but still averaged >40%. …

Differential Susceptibility Of Japanese Beetle, Oriental Beetle, And European Chafer (Coleoptera: Scarabaeidae) Larvae To Five Soil Insecticides, M. G. Villani, Robert J. Wright, P. B. Baker Jun 1988

Differential Susceptibility Of Japanese Beetle, Oriental Beetle, And European Chafer (Coleoptera: Scarabaeidae) Larvae To Five Soil Insecticides, M. G. Villani, Robert J. Wright, P. B. Baker

Department of Entomology: Faculty Publications

Efficacy of bendiocarb, chlorpyrifos, diazinon, ethoprop, and isofenphos was evaluated against last-instar larvae of European chafer, Rhizotrogus majalis (Razoumowsky), Japanese beetle, Popillia japonica Newman, and Oriental beetle, Anomala orientalis Waterhouse, by incorporating insecticides into soil at one-half New York State recommended rates in a laboratory bioassay. Mortality was assessed at 1, 2, 3, 4, and 5 wk. The experiment was repeated three times with white grubs collected at different times and from different locations in New York. White grub species differed significantly in their response to some of the insecticides; European chafer was generally least susceptible. Diazinon provided high mortality …


Alternation Of Sex Ratio In A Partially Bivoltine Bee., Megachile Rotundata (Hymenoptera: Megachilidae), V. J. Tepedino, F. D. Parker May 1988

Alternation Of Sex Ratio In A Partially Bivoltine Bee., Megachile Rotundata (Hymenoptera: Megachilidae), V. J. Tepedino, F. D. Parker

Entomology Papers from Other Sources

Data on offspring production by the alfalfa leafcutting bee, Megachile rotundata (F.), from three site-years were used to examine predictions of parental investment and sex ratio theory. In northern Utah, spring-emergent adults produce two types of offspring: those that develop directly to the adult stage and emerge in midsummer, and those that develop to the prepupal stage and enter diapause until the following year. For species with this kind of life cycle, it has been hypothesized that spring parents should bias their investment in summer emergent progeny towards females if spring males survive to participate in the summer mating. Results …

Entomogenous Nematodes As Biological Control Agents Of European Chafer And Japanese Beetle (Coleoptera: Scarabaeidae) Larvae Infesting Turfgrass, M. G. Villani, Robert J. Wright

Department of Entomology: Faculty Publications

In laboratory studies, infective juveniles of Steinernema feltiae Filipjev (=Neoaplectana carpocapsae Weiser) (All strain) and Heterorhabditis heliothidis (Khan, Brooks & Hirschmann) were tested for their ability to control third-instar European chafer (EC), Rhizotrogus majalis (Razoumowsky), in soil at rates from 19.4-310.0 nematodes per cm2 of soil surface. H. heliothidis provided better control of EC larvae than S. feltiae over the range of rates tested. After 25 d, treatment with H. heliothidis provided 94% control of larvae at the lowest rate tested (19.4 per cm2). In a field test in turf against a mixed population of Japanese beetle, …

The Status Of The Names Clytus Horridus Leconte And Clytus Leucozonus Castelnau & Gory (Coleoptera: Cerambycidae), Richard L. Hoffman Mar 1988

The Status Of The Names Clytus Horridus Leconte And Clytus Leucozonus Castelnau & Gory (Coleoptera: Cerambycidae), Richard L. Hoffman

Insecta Mundi

Much of the confusion that has plagued the two species considered here originated from the failure of previous authors to examine pertinent type material. I made a special effort to examine types of as many names as readily available, and in addition appealed to a number of museums and individuals for the loan of (or information about) material of horridus and muricatulus in order to account for the range and variation of these taxa. C. horridus, although widely distributed, is by no means common and many - even large - collections have few if any specimens of it.

Insecta Mundi

Information on the taxonomy, anatomy, and bionomics of the species of Psalydolytta Peringuey is presented and summarized. Psalydolytta testaceoapicalis Pic, described from Guinea, is placed in the synonymy of P. cineracea (Maklin) (new synonymy). The genus has a disjunct Ethiopian-Indian distribution (42 species in Africa, 10 in India). Adults appear toward the end of the rainy season, are generally nocturnal, and feed largely on flowers and developing grains of wild and cultivated grasses. Adults attracted to lights are sometimes a nuisance because of their ability to produce blisters on human skin. The larva of the Indian P. rouxi (Castelnau) has …

Environmental Effects On Remating In Drosophila Melanogaster, Lawrence G. Harshman, Ary A. Hoffman, Timothy Prout Mar 1988

Environmental Effects On Remating In Drosophila Melanogaster, Lawrence G. Harshman, Ary A. Hoffman, Timothy Prout

Lawrence G. Harshman Publications

The effects of density and food on remating were investigated using Drosophila melanogaster. The frequency of remating was unaffected by density for some combinations of fly strains but was reduced at low relative densities for other combinations. Until females had used most of their stored sperm, remating was less likely when food was absent or contact with food was prevented. Food availability had little effect on the incidence of remating once stored sperm were depleted and had no effect on initial virgin mating frequency. This study indicates that environmental factors can have a substantial direct influence on the frequency …

Native American Plant Hosts Of Asphondylia Websteri (Diptera: Cecidomyiidae), Raymond J. Gagne, William M. Woods Jan 1988

Native American Plant Hosts Of Asphondylia Websteri (Diptera: Cecidomyiidae), Raymond J. Gagne, William M. Woods

USDA Systematic Entomology Laboratory

Asphondylia websteri Felt is reported for the first time from native American hosts, Parkinsonia and jojoba. Previously, this apparently native American gall midge was known only from alfalfa and guar, two species exotic to North America. Such a wide disparity of hosts is otherwise unknown for North American Asphondylia spp. This discovery excludes A. websteri from consideration as a biocontrol agent of Parkinsonia aculeata in Australia.


The Origin Of Chubutolithes Ihering, Ichnofossils From The Eocene And Oligocene Of Chubut Province, Argentina, Thomas M. Bown, Brett C. Ratcliffe Jan 1988

The Origin Of Chubutolithes Ihering, Ichnofossils From The Eocene And Oligocene Of Chubut Province, Argentina, Thomas M. Bown, Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

ABSTRACT-The distinctive trace fossil Chubutolithes gaimanensis n. ichnosp. occurs in Casamayoran (early Eocene) and Colhuehaupian (late Oligocene) alluvial rocks of the Sarmiento Formation in eastern Chubut Province, Argentina. Though known for nearly 70 years, its origin has remained obscure. Examination of new specimens and comparisons with modem analogs demonstrate that specimens of Chubutolithes represent the fossil nests of a mud-dauber (Hymenoptera: Sphecidae). Virtually identical nests are constructed today by mud-daubers in areas as disparate as southern Santa Cruz Province, Argentina, and Nebraska, confirming that quite similar trace fossils can be produced by several different taxa in a higher taxonomic clade. …

Spermiogenesis Of Eupyrene Sperm In Prepupae"} Pupae"} And Adults Of Heliothis Virescens (Lepidoptera: Noctuidae): An Ultrastructural Study, Leo E. Lachance, Geneva Olstad

Entomology Papers from Other Sources

We have examined the ultrastructure of post meiotic eupyrene sperm maturation in testes of prepupae, pupae, and adult Heliothis virescens (F.) males. Emphasis was placed on the structures present in the elongating sperm tail. In each young spermatid, each cell has a nucleus, acrosome derivative, and numerous mitochondria in a large volume of cytoplasm. These mitochondria coalesce to form a body, the nebenkern. As the sperm cell begins to elongate, the nebenkern divides into two mitochondrial derivatives (MDs) of unequal size. The MDs have an outer and inner membrane, and as they elongate and coil in the sperm tail, cristae …
