In autumn, 1997, a powdery mildew on platanus occurred throughout the area of Tokyo, Japan. The fungus formed single conidia and multi-lobed appressoria on hyphae. Therefore, the fungus was identified as an
Oidium sp. of the
Erysiphe polygoni type. The pathogenicity of the fungus to three species of platanus was confirmed by replicating the disease symptoms in an inoculation experiment. Therefore, three species of platanus were added to the list of host plants of powdery mildew fungus. This report is the first record of platanus powdery mildew in Japan.

Gray mold and anthracnose of
Stemona japonica (Blume) Miq. occurred in Hachijo-island of Tokyo Metropolis in 1999-2001. A
Botrytis sp. isolated from the infected plants with gray mold was identified as
Botrytis cinerea Persoon: Fries, while
Colletotrichum sp. isolated from infected plants with leaf and stem blight were identified as
Colletotrichum dematium (Persoon: Fries) Grove and
C. gloeosporioides (Penzig) Penzig & Saccardo. Inoculation tests showed that these fungi were the causal agents of the respective diseases. This is the first report on these diseases in Japan.

Seasonal prevalence of the bean bug,
Riptortus clavatus, caught in water-pan traps baited with synthetic aggregation pheromone of this bug was compared with seasonal abundance of the bugs in a soybean field at Tsukuba in 2001. The population density of the adult bugs in the field showed a bimodal pattern with two peaks in mid-August and mid-September. On the other hand, a single peak was observed in the number of adult bugs caught by the pheromone traps in August by a trap placed beside the soybean field and in late September to early October by a trap in the experimental area near glasshouses. The population trend of the adult bugs caught in the traps in the soybean field was not synchronized with that observed in the field. These results suggest that the pheromone traps may not be an effective means to estimate their population trend in soybean fields.

Hyperparasitism of
Neochrysocharis formosa (Westwood) on the primary parasitoid,
Diglyphus isaea Walker, of
Liriomyza trifolii (Burgess) was observed in a greenhouse of tomato plants where
D. isaea was released. The percentage of the indigenous parasitoid,
N. formosa, in the parasitoid complex emerged from
L. trifolii larvae increased with time during June and July. Parasitism by
N. formosa increased to 100% about two months after the first release of
D. isaea. In this time, most of
D. isaea larvae were hyperparasitized by endoparasites. All parasitoids emerged from
D. isaea larvae were females of
N. formosa. Body size of
N. formosa emerged from
D. isaea larvae was significantly smaller than ones which were emerged from
L. trifolii larvae.

Effectiveness of control by the application of granular or wettable powder clothianidin against
Liriomyza trifolii (Burgess) was evaluated in greenhouse tests on tomato plants. The control effect of granular clothianidin against
L. trifolii was more effective than both nitenpyram and acephate. The larvae of leafminer did not occur on tomatoes for about 3 weeks after a granular application at planting. The application of clothianidin WP was more effective than acephate WP and flufenoxuron EC, and the mortality of middle-stage larvae by clothianidin WP was 36.6% and 54.2%. It was considered that clothianidin has the potential become to be one of the principal insecticides in tomato cultivation.

Harmonia axyridis (Pallas) larvae and adults, chrysopid larvae, mantid larvae and adults,
Piocoris varius (Uhler) adults, and
Agelena opulenta L. Koch nymphs. Of the 47 prefectures in Japan, distribution of the beetle expanded to 39 prefectures by the end of 2001.
