Use Of Aluminum-Foil And Oat-Straw Mulches For Controlling Aster Leafhopper, Macrosteles Fascifrons (Homoptera: Cicadellidae), And Aster Yellows In Carrots., Dwi P. Setiawan, David W. Ragsdale

The Great Lakes Entomologist

Aluminum-foil and oat-straw mulches significantly (P < 0.05) reduced aster leafhopper numbers on carrots compared to an untreated control and a malathion spray treatment during the first half of the growing season. The amount of reflected light was significantly higher in both aluminum-foil and oat-straw mulched plots compared to unmulched treatments. Mulch effectiveness decreased when the closing carrot canopy reduced surface area of reflective mulches and amount of reflected light The percentage of aster yellows-infected plants was significantly lower (P < 0.05) in aluminum-foil and straw mulches and in the malathion spray plots compared to the untreated control. Results demonstrated that aluminum-foil and straw mulches gave control of aster leafhoppers and aster yellows in carrots equal to that of a conventional insecticide spray program.

Total Lipid And Fatty Acid Composition In Male And Female Larvae Of Indian-Meal Moth And Almond Moth (Lepidoptera: Pyralidae), Bh. Subramanyam, L. K. Cutkomp

The Great Lakes Entomologist

The total body lipid and fatty acid composition of last instar larvae of the Indian-meal moth, Plodia interpunctella, and almond moth, Cadra cautella, reared on a turkey mash diet was determined. Male P. interpunctella larvae contained significantly higher (lA-fold) total body lipid than females, while no differences between the sexes of C. cautella larvae were observed. The relative abundance of the fatty acids palmitate, palmitoleate, stearate, oleate, lineoleate, and linolenate was similar in both sexes of P. interpunctella and C. cautella. The accumulation of individual fatty acids in larvae of both the moth species did not correspond to …

Effect Of Prey Density On Diurnal Activity And Ovarian Development In Calosoma Calidum (Coleoptera: Carabidae): Implications For Biological Control Of The Gypsy Moth, Lymantria Dispar (Lepidoptera: Lymantriidae) In The Midwest, Michael R. Jeffords, Laurie J. Case

The Great Lakes Entomologist

Four feeding treatments were used in the laboratory to study the effects of the availability of prey on diurnal behavior and ovarian development of Calosoma calidum. Activity was closely monitored for six weeks. No significant differences were found between male and female behavior patterns. Diurnal beetle activity was found to be inversely related to prey density; in treatments where prey was available, diurnal activity declined during the course of the experiment. At the end of six weeks, dissections of female beetles showed that ovarian development and fat body quantity were dependent upon the number of prey available for consumption.

The Great Lakes Entomologist

(excerpt)

This designation of a neotype, in accordance with the provisions of Article 75(b) of the International Code of Zoological Nomenclature (1985), has to be considered as continuation of the revisional article "Sphinx poecila, a valid North American species (Lepidoptera Sphingidae)" (Riotte 1980).

Rediscovery Of Acanthametropus Pecatonica In The Western Great Lakes Region (Ephemeroptera: Siphlonuridae), Richard A. Lillie, Kurt L. Schmude, William L. Hilsenhoff

The Great Lakes Entomologist

Two nearly mature nymphs of Acanthametropus pecatonica were collected in June 1986 from the shifting sand bottom of the lower Wisconsin River. This is the first known collection of this species in the western Great Lakes region since the original collections of two nymphs by R. E. Richardson in 1926 and 1927.

Northern Distribution Records For Some Nearctic Pompilidae (Hymenoptera), Frank E. Kurczewski, Edmund J. Kurczewski

The Great Lakes Entomologist

Distributional records and nomenclatural changes are presented for 20 species of Nearctic Pompilidae. The records extend the species' ranges northward in North America, are peripheral on the northern boundaries of the ranges, or fill in sizeable gaps in the distributions. Flower records, habitat notes, and remarks on the prey are given for some of the species.

Nest And Prey Of Ageniella (Leucophrus) Fulgifrons (Hymenoptera: Pompilidae), Frank E. Kurczewski, Edmund J. Kurczewski

Biology And Distribution Of Tachysphex Aethiops In Michigan (Hymenoptera: Sphecidae: Larrinae), Mark F. O'Brien

The Great Lakes Entomologist

Tachysphex aethiops is a primarily western species that also occurs in the Upper Peninsula of Michigan. Females nest in mossy, sand slopes and utilize pre-existing burrows of other insects. One shallow, five-celled nest contained a single, third-instar nymph of Spharagemon sp., probably bolli, in each cell. Three prey were parasitized by miltogrammine flies.

Distribution And Host Plants Of Corthylus Punctatissimus (Coleoptera: Scolytidae) In The Lower Peninsula Of Michigan, Richard A. Roeper, Demetrios V. Zestos, Brian J. Palik, Larry R. Kirkendall

The Great Lakes Entomologist

(excerpt)

The pitted ambrosia beetle. Corthylus punctatissimus Zimmerman, infests woody saplings and shrubs 14 mm in diameter or less. The beetle bores an entrance hole into the main stem at soil level and constructs a main gallery tunnel which generally spirals downward in the stem. Egg-niche construction is followed by inoculation of symbiotic fungi and oviposition. The main stem of the host tree wilts as a result of the girdling activity of the beetle. Finnegan (1967) described the life history of C. punctatissimus infesting Acer saccharum Marshall in Ontario and Quebec.

Comparative Biology Of Temperate And Subtropical Bark And Ambrosia Beetles (Coleoptera: Scolytidae, Platypodidae) In Indiana And Florida, Mark Deyrup, Thomas H. Atkinson

The Great Lakes Entomologist

Bark and ambrosia beetles were compared from two intensively studied sites. The Indiana site produced 58 species, the Florida site 57 species; 17 species occurred at both sites. Much greater plant host diversity at the Indiana site seems balanced by more favorable climate at the Florida site. There are more exotic species at the Florida site. Different patterns in feeding habits and mating habits of the beetles are related to the climate and history of the sites in complex ways. A list of the and their habits is included.

Mosquito Larvicidal Activity Of Cassia Tora Seed Extract And Its Key Anthraquinones Aurantio-Obtusin And Obtusin, Valentine C. Mbatchou, David P. Tchouassi, Rita A. Dickson, Kofi Annan, Abraham Y. Mensah, Isaac K. Amponsah, Julia W. Jacob, Xavier Cheseto, Solomon Habtemariam, Baldwyn Torto

All Peer-Reviewed Publications

Background: The edible and medicinal leguminous plant Cassia tora L. (Fabaceae) is known to possess insecticidal properties against a wide range of plant-feeding insects. However, the bioactivity of extracts of this plant and their constituents against vectors of medical importance has been largely unexplored. We investigated the mosquito larvicidal activity of the seed extract and its major anthraquinones against larvae of the African malaria vector Anopheles gambiae (s.s.). Methods: Third-fourth instar larval mortality was observed after 24, 48, 72 and 96 h of exposure to varying doses of the extracts, and two anthraquinones isolates identified using liquid chromatography- quadrupole time …

Ecology And Biology Of The Redbanded Stink Bug, Piezodorus Guildinii (Westwood) In Louisiana, Anup Bastola

LSU Doctoral Dissertations

The redbanded stink bug, Piezodorus guildinii (Westwood) is an invasive stink bug species that was first documented as a soybean pest in Louisiana during the year 2000. This species continues to expand northward in the MidSouth but information is lacking on its biology and ecology in the U.S. In order to determine P. guildinii’s northern range, studies were designed to investigate the cold tolerance ability of this species. The mean supercooling points of adult P. guildinii ranged from highest -8.3 ± 0.2°C in March to the lowest of -11.0 ± 0.2°C in January. Evaluation of lethal exposure time …

Vegetation And Arthropod Responses To Brush Reduction By Grubbing And Stacking, Carter Crouch, J. Alfonso Ortega-Santos, David B. Wester, Fidel Hernández, Leonard A. Brennan, Greta L. Schuster

National Quail Symposium Proceedings

Grubbing is a mechanical brush-reduction technique that allows targeting of mesquite (Prosopis glandulosa) and huisache (Vachellia farnesiana) and can be used to open lanes for hunting northern bobwhites (Colinus virginianus). Follow-up treatments of stacking allow the piling up of downed brush. We initiated this study on the Santa Gertrudis Division of the King Ranch, Inc., Texas, to determine effects of grubbing and stacking on vegetation and arthropod communities important to bobwhite. We hypothesized that grubbing and stacking would be able to selectively remove mesquite and huisache while leaving mixed brush species largely intact. We …

An Improved Biotic Index Of Organic Stream Pollution, William L. Hilsenhoff

The Great Lakes Entomologist

Major improvements were made in using a biotic index of the arthropod fauna to evaluate organic stream pollution. All tolerance values were reevaluated, many were changed, and the scale for tolerance values was expanded to 0-10 to provide greater precision. Keys to larvae of Ceratopsyche have been developed and tolerance values for species in this important genus are provided. Sorting of samples in the laboratory instead of in the field is recommended, and directions for processing and evaluating samples are included.

Economic Thresholds For Central European And North American Wheat Insects, Stanley G. Wellso, Theo Wetzel

The Great Lakes Entomologist

The economic thresholds for implementing control of 24 wheat insect pests from Central Europe and North America are discussed. Additional studies on wheat pests are necessary to better define the existing thresholds.

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

The Great Lakes Entomologist

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.

Change In Nutritional Quality Of Detached Aspen And Willow Foliage Used As Insect Food In The Laboratory, William E. Miller

The Great Lakes Entomologist

Leaves of Populus tremuloides and Salix babylonica held in the laboratory as for feeding insects were analyzed for total nitrogen, total phenolics, and total sugars at 0, 3, and 6 days. More often than not, the three components varied due to leaf age, time since excision, or temperature. Temporal changes altered nutritional balance and probable impact on insect performance, Results suggest that other woody plant species would not remain nutritionally stable for long in the laboratory,

Appearance Of Damage Symptoms And Reinfestation Rates For Christmas Trees Attacked By The Zimmerman Pine Moth, Dioryctria Zimmermani (Lepidoptera: Pyralidae), James W. Yonker, Donald L. Schuder

The Great Lakes Entomologist

Two blocks of Scotch pine Christmas trees were inspected to determine an appropriate time to evaluate Zimmerman pine moth damage, and to determine reinfestation rates for trees previously attacked by this insect. Results showed that damage evaluation should be delayed until mid-August and possibly later, in early fall. Evaluation done before this time could result in underestimation of total damage. In the reinfestation study, previously attacked trees were shown to sustain both a higher rate of reattack and more attacks per tree the following year than control trees. However, at most, only 61 % of the new attacks the following …

Puddling By Female Florida Tiger Swallowtail Butterflies, Papillo Glaucus Australis (Lepidoptera: Papilionidae), J. Mark Scriber

The Great Lakes Entomologist

(excerpt)

Many species from all families of Rhopaloccra have been reported to drink water (Norris 1936). Bates (1863) noted that, in the Amazon, 80 species from 22 genera flocked about the damp edges of water and, with very few exceptions, all of these individuals were males.
