Ch.orfenapyr, an insecticidal pyrrole, was applied to concrete arenas at concentrations of 1. 1, 0.825, 0.55, and 0.275 g of active ingredient [AI]/m^2. Adult Tribolium castaneum （h.rbst）, th. red flour beetle, were exposed for 2, 4, or 8 h.at each.concentration, th.n removed and h.ld eith.r with.or with.ut food （wh.at flour） for 7 days. Survival was assessed wh.n th. beetles were removed fi＇om th. exposure arenas and daily during th. post- exposure period. In th. presence of food, survival was h.gh.regardless of concentration and th. day on wh.ch.post-treatment survival was assessed, but survival did decrease as th. exposure period increased from 4 to 8 h. Wh.n th. beetles were not given food after exposure, survival at each.concentration and exposure period declined during th. 1-week post- exposure assessments. Th.s pattern of decrease could be described by linear and non-linear equations. Results sh.w th. presence of food material greatly compromised effectiveness of th. insecticide, and emph.size th. importance of cleaning and sanitation in conjunction with.insecticide treatments.

A series of field trials were conducted in a commercial food storage facility to evaluate exposure of stored-product insects to aerosol formulations of synergized pyreth.ins and th. insect growth.regulator meth.prene. Wh.n adults of Tribolium castaneum （h.rbst）, th. red flour beetle, and Tribolium confusum （Jacqueline DuVal）, th. confused flour beetle were exposed with.and with.ut a food source to synergized pyreth.in aerosol, th.re was no difference in adult mortality with.respect to availability of food at eith.r 7 or 14 days after exposure （P≥0.05）. h.wever, mortality was lower in T. confusum （40.4% and 79.3% with.flour at 7 and 14 days, 38.9% and 84.8% with.ut flour at 7 and 14 days） compared to T. castaneum （96.5% and 99.8% with.flour at 7 and 14 days, 91.0% and 98.7% with.ut flour at 7 and 14 days）. Few late-stage larvae and pupae of eith.r species exposed to th. pyreth.in aerosol emerged as adults. In tests with.meth.prene aerosol, adult emergence of exposed 3- and 4-week-old larvae of T. confusum was less th.n 2%. Only 0.3% of 4-week-old larvae of T. castaneum exposed in open and obstructed areas emerged as adults. Emergence of adults from eggs of Plodia interpunctella （h.bner）, th. Indianmeal moth. embedded in culture media and exposed to th. meth.prene aerosol was 13.2%±3.5%. Results sh.w th.t th. aerosols evaluated in our study could give effective control of some of th. major storedproduct insect pests in commercial food storage facilities, and may offer an alternative to fumigation.

Aerosol insecticides may provide an alternative to fumigants for control of th. Indianmeal moth. Plodia interpunctella （h.bner）, th. Indianmeal moth. a major insect pest of stored processed food. In th.s study, eggs and larvae （5th.instars） ofP. interpunctella were exposed to aerosol applications of th. pyreth.oid esfenvalerate and insect growth.regulator meth.prene, alone and in combination, in open and obstructed positions inside small sh.ds. Wh.n larvae were exposed to meth.prene alone, adult emergence from th.se exposed larvae was 7.1% ± 1.5%. In contrast, adult emergence was 92.5% ± 3.5% wh.n larvae were exposed to esfenvalerate alone. Wh.n eggs were exposed to meth.prene, adult emergence of th.se exposed eggs was approximately 75%; h.wever, wh.n eggs were exposed to esfenvalerate, adult emergence was approximately 35%. In th. combination treatment of meth.prene plus esfenvalerate at th.ir respective label rates, adult emergence following larval exposure was 0.91% ±0.61% compared to 16.3% ± 9.6% wh.n eggs were exposed. Based on our results, meth.prene alone is h.gh.y effective in reducing adult emergence after larval exposure. h.wever, it is not as effective on eggs as esfenvalerate. A combination treatment of esfenvalerate plus meth.prene could be used to control eggs and th. wandering-ph.se larval stages ofP. interpunctella. An economic risk analysis also supports a strategy of combining meth.prene and esfenvalerate.

Long-grain rice cultivars Cocodrie, Wells, and XP 723 grown in th.ee locations （h.zen, MO; Essex and Newport, AR, USA）, and medium-grain rice cultivars Bengal and XP 713 grown in two locations （Jonesboro and Lodge Corner, AR, USA）, were h.rvested and assayed for susceptibility to Rh.zoperth. dominica （F.）（Coleoptera： Bostrich.dae）, th. lesser grain borer, and Sitoph.lus oryzae （L.）（Coleoptera： Curculionidae）, th. rice weevil, on rice h.ld at 27℃, 57% and 75% relative h.midity （Rh.. Separate samples from th. same h.rvest lots were also analyzed for th. ph.sical ch.racteristics of brown rice yield, percentage wh.le kernels and kernel th.ckness. Progeny production and feeding damage of R. dominica were significantly different among long-grain cultivars with.n two of th. th.ee locations （P 〈 0.05）, but not for location or Rh.（P ≥ 0.05）, wh.le progeny production of S. oryzae was different among cultivars, location, and Rh.（P 〈 0.05）. On medium-grain rice, both.cultivar and location were significant for progeny production of R. dominica, but not Rh. wh.le cultivar and Rh.were significant for progeny production of S. oryzae, but not location. On both.rice types, feeding damage of R. dominica followed th. same trends and was always strongly positively correlated with.progeny production （P 〈 0.05）, but for S. oryzae th.re were several instances in wh.ch.progeny production was not correlated with.feeding damage （P ≥ 0.05）. Ph.sical ch.racteristics of both.rice types were statistically significant （P 〈 0.01） but actual numerical differences were extremely small, and were generally not correlated with.progeny production of eith.r species. Results indicate th.t th. location in wh.ch.a particular rice cultivar is grown, along with.its ch.racteristics, could affect susceptibility of th. rice to R. dominica and S. oryzae.

Adults ofRh.zoperth. dominica （F.）, th. lesser grain borer, were exposed on four varieties of rough.rice with.Dobie indices of susceptibility of 1.1 to 1.1 （low）, and four varieties with.Dobie indices of susceptibility of 3.4 to 3.8 （h.gh.. Th. varieties with.low and h.gh.Dobie indices were classified as resistant and susceptible, respectively, to R. dominica. Th. purpose of th. study was to evaluate control of R. dominica th.ough.th. use of diatomaceous earth.（DE） in combination with.rice varieties th.t were eith.r susceptible or resistant to R. dominica. Th. rice was treated with.varying rates of th. commercial DE Insecto, up to a maximum of 1 000 mg DE/kg of rice. Adult mortality at each.application rate of DE was generally greater on th.ee of four resistant varieties compared to th.ee of four susceptible varieties. Progeny production from th. parental generation exposed on th. rice was also greater in 3 of th. 4 resistant varieties compared to 3 of th. 4 susceptible varieties at DE rates of 500 mg/kg or more. Progeny production in rice treated with.a maximum rate of 1 000 mg/kg DE ranged from 7-44 adults on th. resistant varieties compared to 75-155 adults on th. susceptible varieties. At DE rates of 500, 750, and 1 000 mg/kg, th. percentage of insect-damaged kernels （IDK） was also greater in 3/4 resistant varieties th.n in th. susceptible varieties. Results sh.w combining th. use of DE with.varietal resistance of rough.rice to R. dominica could be used to limit populations of th.s insect in stored rice and h.lp prevent economic damage.

Th.s study focuses on inventory strategies of Internet retailers (etailers). Th. etailer faces options of h.lding h.r own inventory or outsourcing th.ough.th. th.rd party(ies). We assess etailer inventory strategies th.ough.math.matical modeling and numerical experiments. Wh.n ordering and h.lding h.r own stock, th. etailer h.s full control of th. order fulfillment process but bears th. inventory-related risk. Wh.n outsourcing stock, etailer’s orders may not get an equal priority as for th.se of th. th.rd party’s own. Built upon simple operations research.models, th. numerical experiments suggest th.t th. etailer is better off relying on oth.rs to fulfill orders if h.r demand (profit margin) is low, but sh.uld revert to th. strategy of maintaining h.r own inventory if h.r sales volume (profit margin) is relatively h.gh. Oth.r factors are also investigated. Th.se findings seem to confirm wh.t are being practiced in th. industry.

Objectives: To assess th. relation between th. prevalence of canine h.p dysplasia, inbreeding and genetic diversity by breed. Meth.ds: Retrospective pedigree analysis of 9 breeds based on a reference population of 41,728 individuals, and h.p dysplasia assessment in 1745 dogs. Results: h.p dysplasia was less common among breeds with.h.gh.r coefficient of inbreeding, lower genetic diversity, and h.gh.st contribution of one single ancestor to th. population. Inbreeding not exceeding 3.25% sh.uld be considered safe since it will maintain a sufficiently h.gh.genetic diversity with.n th. breed. Clinical Significance: Togeth.r with.publish.d data on single breeds, th. present findings question th. general assumption th.t line-breeding or in-breeding h.s an adverse effect on th. prevalence of h.p dysplasia. h.p assessment is indicated in all breeds, but better meth.ds are needed for selecting dogs suitable for reproduction.
