| revision of the genus stictospora and description of stictospora villani, n. sp. (apicomplexa: eugregarinida: actinocephalidae) from larvae of the japanese beetle, popillia japonica (coleoptera: scarabaeidae), in michigan. | stictospora villani n. sp. is described from larvae of the japanese beetle popillia japonica (coleoptera: scarabaeidae) from southern michigan. stictospora villani is distinguished from known species of the genus by differences in gamont size and by structural details of the epimerite. in general, s. villani is smaller than other known species of the genus and possesses an epimerite with a margin of 20-24 sympetalous, pendulate, narrowly to very narrowly elliptoid lamina. previously described sp ... | 2004 | 15715242 |
| the susceptibility of parental and hybrid willows to plant enemies under contrasting soil nutrient conditions. | we conducted an experimental study of the effects of nutrient addition on the susceptibility of two species of willows (salix eriocephala and s. sericea) and their hybrid to a pathogen and several herbivores. we hypothesized that the relative susceptibility of parental and hybrid willows would depend upon soil nutrient availability and vary among plant enemies. using potted plants in a common garden, we found that s. eriocephala was significantly more susceptible to attack by a fungal rust (mela ... | 1997 | 28307538 |
| impact of elevated co2 and increased temperature on japanese beetle herbivory. | to examine how the major elements of global change affect herbivory in agroecosystems, a multifactorial experiment was conducted where soybeans were grown at two levels of carbon dioxide and temperature, including those predicted for 2050, under otherwise normal field conditions. japanese beetles (popillia japonica newman) were enclosed on foliage for 24 h, after which the beetle survivorship, total and per capita leaf consumption, and leaf protease inhibitor activity were measured. the direct e ... | 2013 | 23955947 |
| elevated carbon dioxide increases salicylic acid in glycine max. | concentrations of carbon dioxide (co(2)) are increasing in the atmosphere, affecting soybean (glycine max l.) phytohormone signaling and herbivore resistance. whether the impact of elevated co(2) on phytohormones and induced defenses is a generalized response within this species is an open question. we examined jasmonic acid (ja) and salicylic acid (sa) under ambient and elevated co(2) concentrations with and without japanese beetle (popillia japonica newman) damage and artificial damage across ... | 2012 | 23321090 |
| role of cysteine proteinase inhibitors in preference of japanese beetles (popillia japonica) for soybean (glycine max) leaves of different ages and grown under elevated co2. | elevated levels of co(2), equivalent to those projected to occur under global climate change scenarios, increase the susceptibility of soybean foliage to herbivores by down-regulating the expression of genes related to the defense hormones jasmonic acid and ethylene; these in turn decrease the gene expression and activity of cysteine proteinase inhibitors (cystpis), the principal antiherbivore defenses in foliage. to examine the effects of elevated co(2) on the preference of japanese beetle (jb; ... | 2009 | 19418071 |
| longevity and fecundity of japanese beetle (popillia japonica) on foliage grown under elevated carbon dioxide. | atmospheric levels of carbon dioxide (co(2)) have been increasing steadily over the last century. plants grown under elevated co(2) experience physiological changes that influence their suitability as food. previous studies have found increased insect herbivory on plants grown under elevated co(2). to determine effects of consuming foliage of soybean (glycine max) grown under elevated co(2) on adult survivorship and fecundity, japanese beetles (popillia japonica newman) were fed for the duration ... | 2008 | 18419934 |
| transcriptional profiling reveals elevated co2 and elevated o3 alter resistance of soybean (glycine max) to japanese beetles (popillia japonica). | the accumulation of co2 and o3 in the troposphere alters phytochemistry which in turn influences the interactions between plants and insects. using microarray analysis of field-grown soybean (glycine max), we found that the number of transcripts in the leaves affected by herbivory by japanese beetles (popillia japonica) was greater when plants were grown under elevated co2, elevated o3 and the combination of elevated co2 plus elevated o3 than when grown in ambient atmosphere. the effect of herbi ... | 2008 | 18194424 |
| distribution and dynamics of japanese beetles along the indianapolis airport perimeter and the influence of land use on trap catch. | as part of a program to minimize the accidental transportation of japanese beetles (popillia japonica) through cargo aircraft to areas where they are not established, a 4-yr trapping project was initiated to study the relative distribution and dynamics of the beetles along a trap line around the indianapolis international airport. land use influence on beetle abundance (trap catch) was assessed using a geographic information system. trap catch was consistently high in some locations and low in o ... | 2007 | 17445363 |
