Residual Action Of Slow Release Systemic Insecticides On Rhopalosiphum Padi (Homoptera: Aphididae) On Wheat, J. E. Araya, J. E. Foster, M. M. Schreiber, R. E. Wing

The Great Lakes Entomologist

Slow release formulations of acephate and carbofuran encapsulated in pearl corn­ starch or corn flour granules were applied to the soil at seeding time of potted 'Caldwell' wheat in the laboratory. Dosages of these insecticides were adjusted to a standard of IO kg/ha of a 10"10 granular formulation of carbofuran. The residual action of these insecticide treatments against Rhopalosiphum padi were compared with those obtained with that of carbofuran 150 at corresponding dosages and foliar sprays of solutions of acephate (25"10 EC) at 0.2"10 and carbofuran (4F) at 1.25"10, applied 12 d after seedling emergence. The residual action of carbofuran …

Late Winter Foraging By Honeybees (Hymenoptera: Apidae) At Sapsucker Drill Holes, Charles E. Williams

The Great Lakes Entomologist

Observations of Apis mellifera foraging at sapsucker drill holes were made during February 1988 in southwestern Virginia. Foraging bouts were dependent upon temperature; more bees visited drill holes when ambient temperatures exceeded 10oC. Honeybees did not feed directly at drill holes but collected congealed sap from bark surfaces.

Marking Adult Colorado Potato Beetles, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae) Using Paper Labels, Michael A. Caprio, Deborah Miller, Edward Grafius

The Great Lakes Entomologist

The smooth elytra of adult Colorado potato beetle, Leptinotarsa decemlineata, make this insect difficult to make efficiently for long-term field studies. Enamel paint marks fell off rapidly, and after 28 days, 25010 of marked beetles had lost all four original marks. Use of small paper labels glued to the elytra after an acetone wash and sanding pretreatment was the most effective method for long term marking of individual beetles. Mortality in labeled laboratory-reared and field-collected beetles did not increase when compared to unmarked beetles.

Survival And Longevity Of Otiorhynchus Ligustici (Coleoptera: Curculionidae) In Alfalfa Hay Bales In Eastern Ontario, D. G. Harcourt, K Bereza

The Great Lakes Entomologist

The alfalfa snout beetle, Otiorhynchus ligustici, a pest of European origin, has recently spread into mainland Ontario. A two-year study showed that dispersing adults incorporated into bales of alfalfa during harvest can survive therein for up to 46 days of storage in a mow. Furthermore, they can remain fertile for most of this period. This has important implications with respect to the shipment of hay from infested areas.

Mass Rearing The Gypsy Moth Pupal Parasitoids Brachymeria Lasus And Brachymeria Intermedia (Hymenoptera: Chalcididae) For Small-Scale Laboratory Studies, S. D. Stowell, H. C. Coppel

The Great Lakes Entomologist

An economical technique was developed for mass rearing the gypsy moth para- sitoids Brachymeria lasus and B. intermedia using a factitious host, the greater wax moth, Galleria mellonella (Lepidoptera: pyralidae). Percentages of host pupae producing adult B. lusus and B. intermedia were 72.2 and 67.5, respectively. Percentages of adult wax moths emerging from groups of pupae exposed to populations of B. lasus and B. intermedia were 3.4 and 9.8, respectively. Mean emergence times of males and females from parasitized pupae incubated at 29° C. were 12.1 days and 13.8 days for B. lasus and 11.9 days and 13.5 days for …

Economic Impact Of The Sugarcane Aphid Outbreak In South Texas, Samuel D. Zapata, Rebekka Dudensing, Danielle Sekula, Gabriela Esparza-Díaz, Raul Villanueva

Entomology Faculty Publications

The objective of this study was to estimate the economic impact of the sugarcane aphid (SCA) outbreak in the Rio Grande Valley (RGV), Texas. Local producers were surveyed to gather detailed information about crop production and pest control practices. Collected data were used to estimate the reduction in profit associated with the SCA infestation, as well as the monetary value of the prevented loss attributed to control efforts. Sorghum industry losses were then used to assess the overall economic impact of the SCA outbreak in the RGV economy.

A History Of The Eastern Larch Beetle, Dendroctonus Simplex (Coleoptera: Scolytidae), In North America, D. W. Langor, A. G. Raske

The Great Lakes Entomologist

The eastern larch beetle, Dendroctonus simplex, is reputedly a secondary pest but may attack and kill tamarack and ornamental larches throughout Canada, the northeastern United Stales, and Alaska. Isolated infestations of this pest have been reported for over 100 years. The first recorded widespread outbreaks of D. simplex started in eastern Canada and the northeastern United States as well as in Alaska in the mid-1970s. During the outbreak in the Atlantic provinces, in excess of 1.4 million m3 of tamarack was killed. No damage estimates are available for Quebec and the United States. Insect defoliators were the most common …

Effect Of Selecting Cereal Leaf Beetle (Coleoptera: Chrysomelidae) Males By Age And Feeding Behavior On Nondiapause Progeny, S. G. Wellso, R. P. Hoxie

The Great Lakes Entomologist

In a nondiapause culture of cereal leaf beetles, Oulema melanopus (Coleoptera: Chrysomelidae), females ovipositing within 20 days after emergence were considered nondiapause. However, sexually active males in the same generation could be nondiapause or prediapause. Changes in the nondiapause incidence were compared between progenies from> 15 day old males that were feeding actively and photopositive (considered 'nondiapause' males) and progenies from younger males (nonselected males). Nondiapause females increased by 19% (n = 35 generations) and decreased 22% (n 31 generations) in the progenies of 'nondiapause' and nonselected males, respectively, suggesting that nondiapause males were selected in the former group, but …

The Insects Of Treeholes Of Northern Indiana With Special Reference To Megaselia Scalaris (Diptera: Phoridae) And Spilomyia Longicornis (Diptera: Syrphidae), Robert S. Copeland

The Great Lakes Entomologist

The aquatic insect community of treeholes in northern Indiana was surveyed from 1983-1986. Twenty-three species, representing three orders and nine families, were found. Megaselia scalaris (Diptera: Phoridae) was collected on several occasions from rotholes, the first member of this family from treeholes. Examination of puparia of Spilomyia longicornis (Diptera: Syrphidae) indicated that the larva of this species has been previously described, but incorrectly associated with the genus Xylata.

Sampling Technique For Larvae Of The Alfalfa Snout Beetle, Otiorhynchus Ligustici (Coleoptera: Curculionidae), D. G. Harcourt, M. R. Binns

The Great Lakes Entomologist

This paper presents a sampling procedure for estimating larval populations of the alfalfa snout beetle, Otiorhynchus ligustici. The method is based on counts of the larvae taken in 16 x 16 cm quadrats of soil during early fall when the grubs are in their final two instars and feeding just below the crowns of the plant. Analysis of sampling variability showed that 200 quadrats per field are necessary to obtain adequate precision for intensive population studies but that 50 quadrats are sufficient for survey work. The pattern of counts was overdispersed but conformed to the negative binomial distribution.

Based upon known biologies of host insects and other mite species which utilize these hosts, it is hypothesized that N. lashingi and N. mydophilus may inhabit wet decaying wood andior …

Ecology, Mating And Nesting Of Tachypompilus Ferrugineus Nigrescens (Hymenoptera: Pompilidae), Frank E. Kurczewski

The Great Lakes Entomologist

An aggregation of Tachypompilus Jerrugineus nigrescens was studied during mid­ summer 1988 in Syracuse, NY. Wasp activity was focused on a 2 m high cemetery monument near a gravelly roadway. Males perched on thc stone, chased one another and pursued incoming females in flight. Details of mating are described. Both sexes spent the night and periods of inclement weather inside a narrow crevice near the base of the monument. Females flew around the monument, landed frequently and made exploratory walks inside of the crevice. They were observed searching for prey and transporting paralyzed spiders backward on the ground. Seven conical …

Effects Of Corn And Selected Weed Species On Feeding Behavior Of The Stalk Borer, Papaipema Nebris (Lepidoptera: Noctuidae), Leticia J. Alvarado, David B. Hogg, John L. Wedberg

The Great Lakes Entomologist

Experiments were conducted in an outdoor insectary to examine behavioral interactions between fifth instar stalk borers, Papaiperna nebris, and potential host plant species. Plants tested included 6- and 8-leaf stage corn, Zea mays, and ten weed species (six broadleaf and four grass) commonly associated with corn production in southern Wisconsin. Broadleaf plants found to be acceptable hosts included Ambrosia trifida, Arnaranthus retroflexus, Rumex crispus, and Chenopodium album; Asclepias syriaca and Abutilon theophrasti were not acceptable as host plants. Corn and the other grass species (Agropyron repens, Bromus inermis, Dactylis glomerata, and Setaria faberi) were found to be acceptable …

Response Of Saddled Prominent (Lepidoptera: Notodontidae) Pupae To Desiccation, Cold Treatment, And Post-Cold Treatment Incubation Temperature, Peter J. Martinat, Douglas C. Allen

The Great Lakes Entomologist

Saddled prominent, Heterocampa guttivitta, pupae were placed at 1.5oC for 50 to 200 days, then incubated at one of four post-cold temperatures ranging from 10° to 26.7°C. Adults emerged from pupae exposed to all cold treatment periods. A few adults also emerged from pupae that were not exposed to cold. The time required for adult emergence following cold treatment declined with longer periods of cold treatment and higher post-cold incubation temperature. The interaction between these two main effects was also significant. Adult morphogenesis begins immediately after pupation, and continues until interrupted by cold temperature. When pupae were subjected to …

Estimating Parasitism Of Colorado Potato Beetle Eggs, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae), By Edovum Puttleri (Hymenoptera: Eulophidae), E. Groden, F. A. Drummond, R. A. Casagrande, J. H. Lashomb

The Great Lakes Entomologist

A computer simulation was used to evaluate methods for estimating parasitism of Colorado potato beetle egg mass populations by Edovum puttleri. The algorithm incorporated the specific attack behavior of E. puttleri, and a development time for parasitized egg masses of ca. 2.9 times that of healthy egg masses. Of the methods compared, a modification of Southwood's graphical technique was found to be most accurate in relation to the true parasitism derived from the algorithm. A regression equation is presented to correct the error in this method at high levels of parasitism. A second simulation was used to test the accuracy …
