Dispersal Of Adult European Corn Borer (Lepidoptera: Crambidae) Within And Proximal To Irrigated And Non–Irrigated Corn, Thomas E. Hunt, Leon G. Higley, John F. Witkowski, Linda J. Young, Richard L. Hellmich Jan 2001

Dispersal Of Adult European Corn Borer (Lepidoptera: Crambidae) Within And Proximal To Irrigated And Non–Irrigated Corn, Thomas E. Hunt, Leon G. Higley, John F. Witkowski, Linda J. Young, Richard L. Hellmich

Department of Entomology: Faculty Publications

The European corn borer, Ostrinia nubilalis (Hübner), causes economic damage to corn, Zea mays L., throughout the Corn Belt. Because this insect has become the primary target of Bacillus thuringiensis Berliner (Bt) transgenic corn, current efforts addressing the management of O. nubilalis resistance to Bt corn require information on adult European corn borer dispersal and factors affecting its dispersal. In 1998 we conducted mark-release-recapture, release-recapture, and caged-mating studies to directly measure and compare local dispersal patterns of O. nubilalis adults within and proximal to irrigated and non-irrigated cornfields. Releases of marked adults were made corresponding to the first and second …

Effects Of Decreasing Thermophotoperiod On The Eastern Subterranean Termite (Isoptera: Rhinotermitidae), Brian J. Cabrera, Shripat T. Kamble Jan 2001

Effects Of Decreasing Thermophotoperiod On The Eastern Subterranean Termite (Isoptera: Rhinotermitidae), Brian J. Cabrera, Shripat T. Kamble

Department of Entomology: Faculty Publications

Eastern subterranean termite, Reticulitermes flavipes (Kollar), workers were exposed to decreasing temperatures and a shift in photoperiod to simulate conditions that are encountered during the fall in eastern Nebraska. Mean water and fat content in termites exposed to a decreasing thermophotoperiod did not differ significantly from controls or laboratory colony termites. Survival was higher for termites subjected to a decreasing thermophotoperiod than for controls. This could be attributed to acclimation to low temperatures or a delayed mortality due to lowered metabolic activity at low temperature. Previously reported data on soil temperatures taken in Lincoln, NE, at a depth of 91.4 …

Development Of European Corn Borer Larvae On Event 176 Bt Corn: Influence On Survival And Fitness, Blair D. Siegfried, Amelia C. Zoerb, Terrence A. Spencer

Department of Entomology: Faculty Publications

European corn borer larvae, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae) that have completed development on Event 176 Bt corn hybrids have survived exposure to sublethal doses of the Cry1Ab Bt toxin or are exploiting plant tissues that do not express the toxin. To evaluate the impact of such exposure, diapausing larvae were collected from Event 176 and conventional hybrids and compared for rates of pupation, parasitism, fitness (pupal weight, longevity, and fecundity) and susceptibility to the Cry1Ab toxin. Larvae completing development on Event 176 corn exhibited approximately 10% higher survival rates and correspondingly lower parasitism rates than larvae completing development on …

Expression And Induction Of Three Family 4 Cytochrome P450 (Cyp4)* Genes Identified From Insecticide-Resistant And Susceptible Western Corn Rootworms, Diabrotica Virgifera Virgifera, M. E. Scharf, S. Parimi, Lance J. Meinke, L. D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

We have previously determined that cytochrome P450-based oxidation is involved in resistance to the insecticides methyl parathion and carbaryl in geographically distinct Nebraska western corn rootworm populations. Three new family 4 cytochrome P450 (CYP4) gene fragments (CYP4AJ1, CYP4G18 and CYP4AK1) were cloned and sequenced from insecticide-resistant and -susceptible western corn rootworms. Insecticide bioassays indicated the resistant population employed in this study was significantly resistant to the insecticides methyl parathion and carbaryl. CYP4AJ1 and CYP4G18 were cloned from both genomic PCR and RT-PCR products, although only CYP4AJ1 contains an intronic region. Alignments of inferred amino acid sequences with other homologous insect …

Induction Of Resistance In Field Grown Soybean By The Bean Leaf Beetle, Cerotoma Trifurcata (Forster) (Coleoptera: Chrysomelidae), Parimi Srinivas, Stephen D. Danielson

Department of Entomology: Faculty Publications

A study was conducted during the summer of 1998 with soybean cultivar Colfax, germplasm line HC95-24MB and susceptible cultivar Williams 82 to investigate induced resistance in soybean. Bean leaf beetle adults were used to induce resistance in field and also in the dual-choice feeding preference tests that were done in the laboratory to assess induction. Pair-wise comparisons of leaflets from induced and control plants demonstrated that induced resistance was present. Preference index (PI) values were similar in the three soybean entries and were not significantly different. Further investigation is necessary to fully understand induced resistance under field conditions in soybean-insect …

Pcr–Rflp Of The Mitochondrial Cytochrome Oxidase (Subunit I) Gene Provides Diagnostic Markers For Selected Diabrotica Species (Coleoptera: Chrysomelidae), Thomas L. Clark, Lance J. Meinke, John E. Foster

Department of Entomology: Faculty Publications

Adult and larval identification of Diabrotica can be difficult. Some adult identifications require considerable taxonomic experience while larvae of many Diabrotica species are morphologically indistinguishable. This study was conducted to determine whether 12 pest and non-pest Diabrotica species could be separated using polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP). A 1308 bp portion of the mitochondrial cytochrome oxidase subunit I gene (COI) was amplified using PCR and digested using several restriction endonucleases. Double digests of COI amplicons with AluI and MspI resolved on polyacrylamide gels revealed several diagnostic inter- and intraspecific polymorphisms. A key to the 12 species …

Female Sensitivity To Diet And Irradiation Treatments Underlies Sex-Mortality Differentials In The Mediterranean Fruit Fly, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Brad Love, Lawrence G. Harshman, Linda Partridge

Lawrence G. Harshman Publications

Large-scale experiments on medflies that were subjected to sterilizing doses of ionizing radiation (plus intact controls) and maintained on either sugar-only or full, protein-enriched diets revealed that, whereas the mortality trajectories of both intact and irradiated male cohorts maintained on both diets are similar, the mortality patterns of females are highly variable. Mean mortality rates at 35 days in male cohorts ranged from 0.2 to 0.3 but in female cohorts ranged from 0.09 to 0.35, depending on treatment. The study reports three main influences: (a) qualitative differences exist in the sex–mortality response of medflies subjected to dietary manipulations and irradiation, …

The Biology, Life History, And Taxonomy Of Celastrina Neglectamajor (Lycaenidae: Polyommatinae)., Harry Pavulaan, David M. Wright Dec 2000

The Biology, Life History, And Taxonomy Of Celastrina Neglectamajor (Lycaenidae: Polyommatinae)., Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

The biology and life history of Celastrina neglectamajor is described. This lycaenid butterfly was first described from West Virginia, United States by 19th century lepidopterist, William H. Edwards, as a redescription of Lycaena pseudargiolus (Boisduval & Le Conte). Edwards provided evidence of its unique late spring flight, Appalachian affinity, and larval host Cimicifuga racemosa (Ranunculaceae). Edwards and subsequent authors, most notably Samuel Scudder of New England, treated it as an infrasubspecific form of the common eastern Celastrina ladon. In 1908 Tutt applied the form name neglectamajor, describing it from one of Edwards’ 1884 figures. For nearly a century, …

Insecta Mundi

Galiano (1971) revised the genus Fluda Peckham and Peckham 1892, and later updated the revision with additional descriptions, including a new species (Galiano 1986). In her original revision, she transferred Keyserlingella perdita Peckham and Peckham 1892, from Colombia, into the genus. This species was described from both sexes, but only the female was adequately illustrated. Galiano (1971) noted that Banks (1929) had examined only the female type of K. perdita when he described the Panamanian Fluda princeps from both sexes. She concluded that the male of K. perdita was lost subsequent to its description but prior to Banks examination. If …
