Infection of Rice stripe virus in Rice Stripe-resistant Cultivar Harboring Stvb-i Gene

Yuriko HAYANO-SAITO

Released: December 25, 2015

p.9-12

Rice stripe disease is one of the viral diseases caused by Rice stripe virus (RSV), and can be controlled effectively by using resistant cultivars. The resistance gene introduced into those rice cultivars is Stvb-i derived from an indica rice cultivar "Modan". In order to understand the mechanism of the stripe resistance, infection of RSV and disease symptoms were examined in detail in rice resistant cultivars harboring the Stvb-i gene, “St. No. 1” and “Tsukinohikari”. Several tens of percent of resistant rice plants were infected with RSV, but not all the infected rice plants showed disease symptoms. The concentration of RSV was low and the viral spread to the upper leaves was suppressed in initial stage of RSV infection as compared to the susceptible rice. Taken together with information on RSV infection in the susceptible rice reported by other researchers, the results in this study suggested a quantitative effect of Stvb-i gene to viral infection and propagation in and around the apical meristem in the initial stage of RSV infection.

Gray Mold and Sclerotinia Rot of Okra Plants

Masaharu KUBOTA, Tomoo MISAWA

Released: December 25, 2015

p.43-46

In November 2007, fruits of okra (Abelmoschus esculentus) cultivated in a nursery were found rotted in Mie prefecture. Petals had not fallen and remained on the fruits. The causal agent of the fruit rot with a pale brown color was identified to Botrytis cinerea and that with a white color as Sclerotinia sclerotiorum. On the other hand, leaf rot of okra was found in a nursery in Hokkaido in July 2008. Rotted petals remained on the leaves after falling from fruits. The causal agent was also identified as B. cinerea. This is the first report of okra diseases during cultivation caused by B. cinerea and S. sclerotiorum in Japan.

In 2012, pineapple lily (Eucomis autumnalis), prairie poppy mallow (Callirhoe involucrata), creeping phlox (Phlox stolonifera) and white cup (Nierembergia rivularis) were blighted in flower beds in Saitama Pref., and similar symptoms occurred in melampodium (Melampodium paludosum) in flower beds in Tokyo Metro. The pathogens isolated from each diseased plant were identified as Sclerotium rolfsii by morphological observations. In addition, the homology of the rDNA-ITS region is high to that of S. rolfsii. This is the first report of the diseases in Japan.

Susceptibility to Diamide Insecticides in Four Local Populations of the Diamondback Moth, Plutella xylostella in Chiba Prefecture

Ken SHIMIZU, Tooru OOTANI, Toshiyuki KAWANA, Masaki ENDOU

Released: December 25, 2015

p.137-140

We investigated susceptibility to two diamide and ten other insecticides in four local populations of the diamondback moth, Plutella xylostella collected from cabbage (Brassica oleracea var. capitata) fields in Asahi City, a rape flower (Brassica rapa var. nippo-oleifera) field and a daikon (Raphanus sativus var. longipinnatus) field in Minamibousou City from October to December 2013 in Chiba Prefecture. For the larvae of two Asahi populations, fed with cabbage leaf disks treated with flubendiamide or chlorantraniliprole, the corrected mortalities at 72 hours after treatment were zero and the leaf areas damaged by the larvae were not significantly different from that of the control, showing a reduced susceptibility to these diamide insecticides. On the other hand, these diamide insecticides were highly effective against two Minamibousou populations. Spinetoram, emamectin benzoate, indoxacarb, tolfenpyrad, Bt and cartap hydrochloride were highly effective against all four populations.

Influence of Sugar Solutions Provided by a Food-supply Device on the Longevity and Life-time Fecundity of Cotesia vestalis, a Larval Parasitoid of the Diamondback Moth Plutella xylostella

p.141-144

We investigated the influence of sugar foods presented in a bottle-type feeding device on female longevity and life-time fecundity of Cotesia vestalis, a larval parasitoid of the diamondback moth Plutella xylostella. Solutions of honey and sugar mixture (sucrose, glucose and fructose) prolonged female longevity significantly more than water, irrespective of the mating status and oviposition experience. These sugar foods also significantly enhanced life-time fecundity of mated parasitoids more than water. We also investigated the continuity of these sugar foods in bottle-type feeding devices installed in a greenhouse for different periods (30 and 120 days). Even 120 days after the installation of these feeding devices, honey and sugar mixtures in feeding devices could respectively enhance female longevity in laboratory experiments. These results indicated that those sugar foods provided by bottle-type feeding devices are useful for maintaining the parasitoids for at least several months in a greenhouse where potential sugar sources (e.g. flowers) are limited.

Effects of Several Insecticides on the Emergence of Encarsia smithi (Silvestri) Parasitizing the Tea Spiny Whitefly Aleurocanthus camelliae Kanmiya & Kasai

Released: December 25, 2015

p.159-162

The effects of several insecticides on the emergence of the parasitoid, Encarsia smithi (Silvestri) parasitizing the tea spiny whitefly Aleurocanthus camelliae Kanmiya & Kasai were evaluated by both laboratory and field experiments. Tea leaves with the pupae of A. camelliae parasitized by E. smithi were collected from a tea field and these leaves were dipped in 13 insecticides diluted with water to ordinary use concentration, and the emergence rate of the parasitoid was checked one month after the treatments in the laboratory experiment. In the field experiment, the emergence rate of the parasitoids was checked 70 days after the application of 13 insecticides in a tea field. The results of these experiments showed that machine oils (two dilutions), methidathion, profenofos and tolfenpyrad were seriously harmful; clothianidin, spinetoram, fenpyroximate·bupurofezin mixer, and methomyl were slightly harmful; and spiromesifen, chlorfenapyr, pyrifluquinazon and diafenthiuron were harmless on the emergence of E. smithi.

Bactericidal or Bacteriostatic Effect of Chlorine Dioxide on the Plant Pathogenic Bacteria Occurring in Hydroponics

Koji AZEGAMI, Masaharu KUBOTA, Takayuki KASHIWABARA, Akimasa NAKANO

Released: December 25, 2015

p.168-171

Bactericidal or bacteriostatic effect of chlorine dioxide (ClO₂) on the plant pathogenic bacteria occurring in hydroponics was examined. In distilled water, 0.1 ppm ClO₂ showed an effect on Pseudomonas cichorii (bacterial rot of lettuce), Pectobacterium carotovorum subsp. carotovorum (bacterial soft rot of lettuce), Pec. c. ssp. odoriferum (causing similar symptoms on lettuce as are caused by ssp. carotovorum), and on Ralstonia solanacearum (bacterial wilt of tomato) in a minute. In hydroponic culture fluid, 0.5 or 1.0 ppm ClO₂ showed an effect on them in a minute. Thus, ClO₂ is a potential control agent or a disinfectant for the diseases occurring in hydroponics.
