| binding of cyt1aa and cry11aa toxins of bacillus thuringiensis serovar israelensis to brush border membrane vesicles of tipula paludosa (diptera: nematocera) and subsequent pore formation. | bacillus thuringiensis serovar israelensis (b. thuringiensis subsp. israelensis) produces four insecticidal crystal proteins (icps) (cry4a, cry4b, cry11a, and cyt1a). toxicity of recombinant b. thuringiensis subsp. israelensis strains expressing only one of the toxins was determined with first instars of tipula paludosa (diptera: nematocera). cyt1a was the most toxic protein, whereas cry4a, cry4b, and cry11a were virtually nontoxic. synergistic effects were recorded when cry4a and/or cry4b was c ... | 2007 | 17416690 |
| evaluation of entomopathogenic fungi and a nematode against the soil-dwelling stages of the crane fly tipula paludosa. | larvae of the crane fly tipula paludosa (diptera: nematocera) are economically important pests of grasslands, nurseries and organically grown crops. this study was conducted to evaluate several entomopathogenic fungal strains, the entomopathogenic nematode heterorhabditis bacteriophora and the organophosphate insecticide dursban wg (75% chlorpyrifos) against larval stages of t. paludosa under laboratory and greenhouse conditions. | 2012 | 22740286 |
| n-terminal polyhedrin sequences and occluded baculovirus evolution. | a phylogenetic tree for occluded baculoviruses was constructed based on the n-terminal amino acid sequence of occlusion body proteins from six baculoviruses including three lepidopteran nuclear polyhedrosis viruses (npvs), [two unicapsid (bombyx mori and orgyia pseudotsugata) and one multicapsid (orgyia pseudotsugata)]; one granulosis virus (pieris brassicae); and npvs from a hymenopteran (neodiprion sertifer) and a dipteran (tipula paludosa). amino acid sequence data for the b. mori npv were fr ... | 1981 | 7026796 |
| characterization of an iridescent virus isolated from the velvetbean caterpillar, anticarsia gemmatalis. | an insect iridescent virus has been isolated from diseased velvetbean caterpillars, anticarsia gemmatalis, found in argentina. the cytopathology is similar to that reported for other iridescent viruses with infected larvae exhibiting blue-purple opalescence. icosahedral particles (n = 119) purified by sucrose gradient rate zonal centrifugation had dimensions of 145 +/- 7 nm (point-to-point) and 136 +/- 12 nm (side-to-side). the sedimentation coefficient was 2250 +/- 10 s20,w when the virus was s ... | 1995 | 8568281 |
| application timing and efficacy of alternatives for the insecticidal control of tipula paludosa meigen (diptera: tipulidae), a new invasive pest of turf in the northeastern united states. | two invasive crane flies, tipula paludosa meigen and tipula oleracea l. (diptera: tipulidae), were detected in new york state for the first time in 2004. both are damaging pests of turfgrass and other horticultural systems in north america where establishment has already been documented. to develop management recommendations for the northeast and define opportunities for preventive (autumn) and curative (spring) control, four insecticide trials targeting t. paludosa larvae were conducted over a ... | 2008 | 18416446 |
| genetic and electron-microscopic characterization of rickettsiella tipulae, an intracellular bacterial pathogen of the crane fly, tipula paludosa. | rickettsiella tipulae is an intracellular bacterial pathogen of larvae of the crane fly, tipula paludosa (diptera: tipulidae) and has previously been claimed to represent an independent species within the genus rickettsiella. recently, this taxon has been reorganized and transferred as a whole from the alpha-proteobacterial order rickettsiales to the gamma-proteobacterial order legionellales. here we present the electron-microscopic identification of this rickettsial pathogen together with the f ... | 2008 | 18374354 |

| the genome of a baculovirus infecting tipula paludosa (meig) (diptera): a high molecular weight closed circular dna of zero superhelix density. | a characterization of the genome of a baculovirus infecting the diptera, tipula paludosa meig, is presented here. it appears to be a double-stranded closed circular dna. the supercoiled structure has been visualized by electron microscopy. the relaxed molecules have a contour length of 51.2 +/- 1.5 mum which corresponds to a molecular weight of 92 x 10(6) daltons, by taking the value of 6.4 x 10(6) daltons for pm2 dna used as an internal standard for the spreading. t. paludosa baculovirus dna ha ... | 1979 | 18631596 |
| matched filtering by a photoreceptor membrane. | this study demonstrates how phototransduction cascades and membranes tune photoreceptor response dynamics to image quality, and eliminate noise introduced in cell signalling. intracellular recordings from intact retina confirm that the light-adapted photoreceptors of the crane fly tipula paludosa (diptera; tipulidae) have a slow response, appropriate for their visual ecology. to provide a slow response, the phototransduction cascade's impulse response fails to narrow with light-adaptation, despi ... | 1996 | 8759456 |
| first description of the disease by conidiobolus osmodes on tipula paludosa larvae with the report of a natural epizootic. | a new fungal pathogen of tipula paludosa (tipulidae: diptera) larvae, conidiobolus osmodes (ancylistaceae: entomophthorales), was found during a survey of tipulid larval pathogens in northumbria and cumbria in england in 1997-1999. the fungus caused an epizootic in a population at close house during autumn 1999 and spring 2000 with prevalence rising fourfold reaching about 40% in april 2000. the disease development was presented and the fungus was described from naturally infected larvae and art ... | 2003 | 14615216 |
| effect of diplocystis tipulae sherlock (eugregarinida: apicomplexa), a coelomic gregarine pathogen of tipulids, on the larval size of tipula paludosa meigen (tipulidae: diptera). | this study demonstrates the debilitative effect of a coelomic gregarine, diplocystis tipulae, on tipula paludosa. the larvae were provided contaminated fresh grass leaves from a field where 40.0% of t. paludosa larvae were infected by this pathogen. resultant infected larvae were separated into four groups according to infection level. analysing their weights, lengths, and weight/length ratios showed that larval size decreased as infection level increased. differences, especially at the lower an ... | 2005 | 15882868 |
| synchronized dynamics of tipula paludosa metapopulation in a southwestern scotland agroecosystem: linking pattern to process. | synchronization of population fluctuations at disjoint habitats has been observed in many studies, but its mechanisms often remain obscure. synchronization may appear as a result of either interhabitat dispersal or regionally correlated environmental stochastic factors, the latter being known as the moran effect. in this article, we consider the population dynamics of a common agricultural pest insect, tipula paludosa, on a fragmented habitat by analyzing data derived from a multiannual survey o ... | 2013 | 23933728 |
| invasive tipula (diptera: tipulidae) in turfgrass of the northeast united states: geographic distribution and local incidence three years after detection. | two species of invasive crane flies are damaging pests of turfgrass in the great lakes region after their inadvertent introduction and establishment. in new york, where tipula paludosa meigen and tipula oleracea l. (diptera: tipulidae) were first detected in 2004, baseline data on the extent of establishment is needed to monitor range expansion, make predictions about pest status, and guide management efforts. the incidence of both species was therefore addressed at two spatial scales to ascerta ... | 2009 | 19449646 |
