    1. Reliance wheat, a differential variety to wheat stem rust, often showed resistance and high susceptibilities to the same isolate of rust fungus. This makes determination of physiological races of Puccinia graminis difficult.
    2. Varying reactions to the same isolate of the fungus was obtained in an inoculation test conducted on Reliance wheat grown in two different localities. In this test the race 21 of the rust fungus reacted to the Morioka grown wheat as type 0 without exception, but on the Konosu grown wheat it was mostly 4 with some 0. On race 56 the wheat from both sources reacted as type 4.
    3. This varying reaction of Reliance wheat to P. graminis was believed to have been caused by the possible hybridization with some other varieties on the Konosu and unlikely to the physiological changes brought about to the wheat as a result of having it grown under different environmental condition of the locality.
    4. When growing Reliance wheat to be used as differential variety extreme care is required in order that the variety identity is not lost.
    5. Isolates of P. graminis obtained in Nagasaki and Kagoshima prefectures and tested in 1959-1962 belonged to race 21 which was in accord with the report Of YAMADA et al. (1961).

    Studies were conducted in 1962 on the dispersal of granular insecticides by the Bell 47 G helicopter.
    The helicopter was flown at a height of approximately 5 meters from the ground level along paths marked at intervals of 18 meters. The insecticides were applied from a spinning disc distributor at a rate of 30 kg per hectare. Sampling vessels were placed along lines laid at right angles to the line of flight paths to receive the granules as they fall.
    The width of both up-and down-wind swaths obtained was about 18 meters, but the distribution pattern of granules was not similar between them. The distribution of granules within the swath was not uniform, and its seemed to be related to the size of granules and the mechanical composition of insecticide.
    Of the components of the tested insecticides, a more uniform distribution was obtained from granules larger than 1.0 mm in diameter, then those smaller than 1.0 mm in diameter which showed tendency to fall in narrower width with greater variation of deposit across the swath.

    Based on a series of counts obtained in a paddy field of about 30 ha. divided into 6 subareas with different insecticide treatments, frequency distributions in each subarea of both the catch by suction machine for the green rice leafhopper, Nephotettix cincticeps and the number of infested stems per 10 rice hills for the rice stem borer, Chilo suppressalis were analyzed.
    Statistical examination of the relationship between mean and variance for both series of distributions revealed that they can be well described by the negative binomial distributions with respective values of common κ (Figs. 1 and 2). On the basis of this result, several problems related to the method of assessing pest populations in wide-areas of paddy fields were discussed (Tables 1, 2 and 3).

    A study was made on the absorption and translocation of 1-14C-naphthyl N-methylcarbamate (NAC) by the rice plant at 1, 3, 7, and 14 days after soil treatment. Suspension of 416 micro grams of NAC toxicant was applied to different layers of each pot containing 500 grams of dry soil. Four methods were used to apply insecticide to the soil: (a) deep placement, (b) application to whole soil, (c) shallow placement, and (d) application to surface water. Just after the application of insecticide, rice seedlings were transplanted on treated soils which were held under flooded condition. The radioassay of extracts from plants, surface water, and soils was made by a Geiger-Muller counter, and the metabolites in the extracts were separated by the paper chromatography.
    The results obtained were summarized as follows:
    1. The detected amounts of radioactive materials per unit weight of the plant by application (c) and (d) were larger than the others, but decreased rapidly at the end of 14 days after treatment.
    2. The amount of uptake of radioactive materials by the rice plant was associated with the radioactivity present in the surface water. This trend was particularly evident in the case of the leaf blade. It seemed that the radioactive materials dissolved in surface water were absorbed into the tissues through the lower part of leaf sheath and translocated to the leaf blade, probably along the stream of plant. sap. However, the detected amount of radioactive materials from the plant had but little association when the radioactivity of the surface water was only a trace or none, and that some portion of radioactive materials in the plant may have been due to what was absorbed through the root.
    3. Recoveries of radioactive materials from the soils applied by (b) and (d) methods, some 50 days later experiment, were respectively 105.0 and 36.3 per cent of the theoretical, which include the absorbed amount by the rice plant.

    Examinations were made on the distribution and decomposition of 32P-labeled Baycid in larval tissues after topical application and oral administration to the larvae of Prodenia litura FABRICIUS, and the absorption and decomposition on larvae and pupae of 32P-labeled Baycid topically applied to the insect bodies.
    The results summarized were as follows :
    1. The partition ratio, (c/c+w)×100, in which c shows radioactivity in chloroform phase and w in aqueous phase, of radioactive materials in various larval tissues was similar between 187 r and 48 r. applications, although the concentration of radioactive materials in various larval tissues was higher when the topically applied doses were higher.
    2. The concentration of radioactive materials in larval haemolymph became gradually higher following topical and oral applications in the larvae that died after 24 hours, but the concentration became gradually lower on those that survived.
    3. The highest concentration of radioactive materials within various tissues, except haemolymph was detected from alimentary canal at 48 r application, and from fat body and alimentary canal at 187 r application. The partition ratio of fat body after topical application was higher than those of any other tissues.
    4. The larvae absorbed almost all topically applied doses within 24 hours, whereas the pupae absorbed less than 17% of the applied doses within 48 hours. The larvae decomposed the absorbed doses more readily than the pupae.

    1. Among the nematodes found in Kyushu and identified by the authors, the following were regarded noteworthy from the viewpoints of nematode distribution-and parasitism: (1) Aphelenchus avenae and Paraphelenchus amblyurus from the soil of sweet potato field in Arao City, Kumamoto Pref., (2) Gracilacus from the soil of mulberry (Morns bombycis) garden in Mizuho Village, Nagasaki Pref., soil of korai-shiba (Zoysia matrella var. tenuifolia) garden in Unzen, Nagasaki Pref., soil of paniculata (hinoki, Chamaecyparis obtusa, and sasa, Sasa albo-marginata) in Kuroishibaru, Kumamoto Pref., (3) Helicotylenchus dihystera, from the upland soils gathered. throughout Nagasaki Pref., (4) Hemicriconem oides sp., from the soil of korai-shiba garden in Unzen, Nagasaki Pref., (5) Nothotylenchus, from the buds of strawberry plant in Kanoya City, Kagoshima Pref., (6) Pratylenchus thornei, from the upland soil in Ojika Island, Nagasaki Pref., (7) P. peneprans, from the soil of chrysanthemum in Kashima City, Saga Pref., (8) Pratylenchus sp., from the soil of loquat (Eriobotrya japonica) garden in Nagasaki City, Nagasaki Pref., (9) Tylenchorhynchus brevidens, from the upland soil in.Iki. Island, Nagasaki Pref., (10) T. nothus, in Mizuho Village and Kuchinotsu Town, Nagasaki Pref., (11) Tylenchorhynchus spp., in Nagasaki Pref.
    2. In regard to the root-lesion nematodes of the common fields in Kyushu, Pratylenchus coffeae was most frequently found and the damage was most conspicuous. Damage by P. zeae was of next order in seriousness.
    3. Seven species of the stunt nematodes are known in Kyushu as based on investigation conducted by the latter author.

    Erythroneura apicalis, NAWA (nom. jap. Futaten-hime-yokobai) has been known as only one Japanese species of grape leafhopper. In 1961, however, one of the authors recognized another leafhopper, Erythroneura suzukii MATS. (nom. jap. Suzuki-hime-yokobai), attacking grape leaves in Fukuoka district. This may be a new record of damage caused by the species, E. suzukii, from Japan.
    The two species can be distinguished by some of their morphological characters and injuring habit,
    as shown in accompanying figures.

    1. Laboratory tests were conducted using dipping method to reveal the effects of insecticides on the second generation pupae of Anicetus benefzcus IsHII et YASUMATSU, the most effective parasite of Ceroplastes rubens MASKELL in citrus groves.
    2. The insecticides, which had poisonous effects on the pupae inside the scale body and reduced the emergence of parasites, were Parathion, Malathion and Fussol (monofluoroacetamide 10%). Kelthane, Mikagin (CPAS 25%, DDDS 10%, DCPM 15%), Phencapton (CMP 18 %), EPN, Ekatin (Thiometon 20%), Bayer-4741, Methyldemeton, Dimethoate and Sevin were not effective when applied during the pupal stage of parasites.
    3. Parathion and Malathion reduced the emergence of parasites for more than 20 days-after treatments. Fussol was effective only for the first 5 or 10 days.
    4. Of the five systemic insecticides tested on pupae of parasites, Fussol was found most effective. It is believed that Fussol is better able to penetrate the covering wax of the scale than the other systemic insecticides.

    Such ants as Crematogaster laboriosa SMITH and Iridomyrmex itoi FOREL often prey on the larvae of D.spectabilis which have recently hatched from the egg mass. Ants attack the larva which have just made its. emergence hole as well as killing the larva within the egg.
    The evidence of such predatism by ants was shown in the hatching egg mass of D.spectabilis, and in many eggs within an egg mass attacked by ants each egg-shell was untouched except for a part of the emergence hole of the larva (Fig.1, A). On the other hand, in the egg mass that was unattacked by ants, a greater part of each egg-shell was eaten by a newly hatched larva (Fig. 1, B).
    A preliminary survey was done at a plot in a Japanese black pine forest on the sea coast near Fukuoka City in July, 1962. From the data obtained (Table 1) it was shown that the percentage of predatism by ants was 16.7%, which was about twice as much as the percentage of parasitism by egg parasites (Trichogramma dendrolimi MATS. and others). The same data indicate that the ants tend to attack greater numbers of hatching larvae within an egg mass, while parasitic wasps do to parasitize smaller numbers of eggs within an egg mass regardless of the size of the egg mass (Fig.2). It is believed that such difference between predatism by ants and parasitism by egg parasites may arise from the aggregating behavior of ants and the synchronized hatching of eggs within the egg mass of D. spectabilis.
    T.dendrolimi emerging from the host egg was also attacked by C. laboriosa.
