    The third to sixth instar larvae of Spodoptera littoralis (BOISDUVAL) (Prodenia litura) were fed on white clover leaves with nuclear polyhedra of Spodoptera for 24 hrs. Then the larvae were reared individually on untreated leaves at 25°C. Larval body weight were surveyed every day.
    It was observed that infected larvae tended to die in non-molting form, decreasing their body weight (cf. Fig. II). It was, also, observed that larvae inoculated at the fourth or the fifth larval instar and let fall into the polyhedrosis, probably, at an early half of the sixth or the last instar grew more slowly than healthy larvae did, and some of them reached the body weight of normal full grown larvae at the time of prepupal or pupal stage of healthy insects. (cf. Fig. III &. Table III).
    The delay of growth of infected larvae observed at the last instar could be understood from a abnormality that the infected larvae could not increase .and decrease their body weight so rapidly as normal larvae did.

  • Dispersal of Allotropa sp. (Hymenoptera, Platygasteridae), a parasite of persimmon and citrus pest, Planococcus kraunhiae KUWANA (Hemiptera, Pseudococcidae), Iiberated in a persimmon grove

    The dispersion of Allotropa sp. liberated in a persimmon grove was examined. 7, 500 mummies of Allotropa sp. were released as an attempt to control Planococcus kraunhiae Kuwana. The mummies were released on four trees in a grove of 20a, where the host population density was relatively low.
    Distance of the dispersion was estimated from the number of individuals of this parasite which stuck to "Haetori Ribbon" a kind of sticky trap. The sticky traps were hung on 20 trees, five of which were inside of the grove and the others were outside. Each one was placed on three parts of the tree, upper, medium, lower, by tying it on a thread hung from the top branch.
    Before releasing the parasite, these traps were left hanging for a day to know the number of individuals of the parasite originally living there. At the time of release other new traps were hung and collected seven days after.
    Inside of the grove, the average number of the parasite increased by approximately three times after release, which was observed on the traps located at about 10m from the trees released. Outside of the grove, however, average number was reduced to about a half after release, although an increase was observed at No. 16 situated at 8.5m from the nearest tree released.
    From this investigation; it may be concluded that this parasite dispersed to a distance of about 10m and the present result agrees approximately with the estimation by Tanaka & Ko-bayashi (1967) and it seems to disperse searching the host hovering about the height of 2m or higher, the medium and upper parts of the crown. From this result, it can be expected to use this parasite as a biotic insecticide.

  • Studies on the Acaricides Resistance of the Citrus Red Mite, Panonychus citri (McG.) IV. Genetics of Resistance to Phenkapton

    To analyse the genetic make-up of Phenkapton-resistance, haploid F2 eggs produced by the F1 virgin females (hybrids) of reciprocal crosses between resistant and susceptible individuals, and haploid F3 eggs produced by F2 (backcross progenies) were tested toxicologically. These eggs were dipped for 5 seconds in water solution of 1:2000 Phenkapton.
    The haploid F2 eggs produced by F1 virgin females showed a high degree of non-viability which hampered further genetic analysis. In addition, the sterile female in F1 virgin female (SS×R) was about 40%. (Table 2 and 3)
    The present ovicidal test suggested that one major gene was responsible for resistance to Phenkapton. However, it is a problem to determine the resistance level by the corrected egg mortality alone, because the haploid F2 eggs produced by F1 virgin females showed high degree of non-viabilty.
    Therefore, adultcidal test for resistance was carried out with 1:15000 dilution of Phenkapton against the various lines of female and male adults. This concentration consistently gave 100% adult mortality of S strain and no mortality of R strain (Fig.1).
    No significant difference in resistance level was found between the F1 female adults of the crosses RR×S and SS×R the mortality being 54% and 66%. Mortalities of the F2 female adults (backcross progenies) of (RR×S)×R and (SS×R)S were 24% and 74% (Table 4). The present results agreed well with the calculated values on the assumption that the F1 female adults showed 60% mortality.
    We concluded that resistance to Phenkapton in Panonychus citri (McG.) was due to a single incompletely dominant gene. The character was transmitted by either sex.

  • Studies on the Acaricide Resistance of the Citrus Red Mite, Panonychus citri (McG.) V. Relation between the resistance to Phenkapton and one of the esterase bands detected by the thin layer electrophoresis

    The purpose of this investigation is to make clear the relation between resistance level to Phenkapton and character of E1 esterase detected by thin layer electrophoresis.
    Activity of E1 esterase was calculated as follows. The size and colour density of each band, which was thought to signify the activity of each separated esterase, were transformed to the area enclosed with density curve by densitometer, and then the rate of the area of E1 esterase band to the whole was calculated.
    Resistance level to Phenkapton was estimated from the corrected mortality (Abbott) of eggs. By using β-Naphthyl acetate as a substrate, the esterase was separated into four bands, which were designated as E1, E3, E4 and E5 band. The colour density and area of E1 band as the activity of E1 esterase, showed individual difference. All the individuals of following four hybrid progenies showed presence of E1 band; RR×R, F1 (RR×S)×R, RR×S and SS×R. In F1(SS×R)×S progeny about 65% of individuals showed presence of E1 and the susceptible strain SS×S showed no E1. Therefore, it may be said that the mite having the resistant factor even as a heterozygote, showed E1 band, and the individuals without resistant factor did not show. Difference of the activity of E1 esterase was observed between male and female of resistant strain. The male showed higher activity than the female. The activity of E1 esterase of the hybrid progeny of resistant and susceptible strains was lower than pure line of resistant strain.
    The activity of E1 esterase correlated closely with resistance level to Phenkapton. A correlation coefficient of r=-0.854 was obtained.
    In conclusion, the E1 esterase is responsible for genetic factor of Phenkapton resistance, and the resistance level depended on the rate of E1 esterase activity.

    Three kinds of spray programs named ordinary (9-10 times of spraying in one year), economic (5-8 times in one year) and minimum (3-5 times in one year) programs were carried out and the results were compared by the percentage of damaged fruits in each orchard. The experimental orchards were well managed and the density of insect pests and diseases was very low.
    In 1966 and 1967, the differences in the ratio of damaged fruits among these three kinds of orchards were neglisible. In 1968, it was observed that the damaged fruits were most abundant at the orchard of minimum program, but the differences were not so important.
    In conclusion, it seems that the minimum types of spray program (only three or four times of spraying in one year) may be adopted and the remarkable curtailment of expenditure may be possible in citrus orchards in which the damages by pests and diseases were scarcely observed.

    Mainly in May to September of 1966, 120 samples of uncultivated soils were collected from natural grasslands and some woody areas including native pastures which spread over 50 locations throughout Japan. Known and suspected plant-parasitic nematode genera isolated from soils mentioned above are as follows : Meloidogyne, Pratylenchus, Heterodera, Helicotylenchus, Paratylenchus, Holotylus, Tylenchus, Criconema, Criconemoides, Hemicriconemoides, Aphelenchus, Trichodorus and Xiphinema. Of the genera, Paratylenchus most prevailed in these habitats, and Helicotylenchus and Pratylenchus were found frequently. Meloidogyne occurred in uncultivated soils in various places of Japan.

    In May 1964, an inspector of the Moji Plant Protection Station of the Ministry of Agriculture and Forestry at Sasebo, Kyushu, found a number of maggots infesting radishes from America. It was learnt that the maggots could not survive at room temperature then. Consequently, a series of flies were obtained after the maggots had been reared in a refrigerator at about 5°C. The insect was supposed to belong to the genus Hylemya, but we failed to obtain positive identification of the species.
    In 1967, Mr. A. C. Pontoof the British Museum (Natural History) examined the insect and determined it as Hylenzya brassicas (Bouché), which was confirmed by Mr. D.M. Ackland of Hope Department of Zoology, University of Oxford.
    Hylemya brassicae, known as the cabbage maggot in economic literature, is a serious pest of cabbage, cauliflower, radish, and other plants of Cruciferae. The maggot is of European origin, but now widespread over North America as a result of the casual introduction in the 19th century. It is not likely that the maggot can succeed in establishing itself in greater parts of this country, largely due to its low hot-hardiness. Some areas in Hokkaido and the mountainous areas in Hnoshu may harbour the maggot, should it be introduced directly into those areas. The author is indebted to Mr. A.C. Pont of the British Museum, Mr. D.M. Ackland of Hope Department of Zoology, University of Oxford, for identifying the fly.

    In autumn of 1968, population density of aphids on seed born Leaf Roll Virus infected potato plants was examined.
    Number of the green peach aphid, Myzus persicae SULZER on diseaed plants was about twice as much as on healthy plants (Fig. 1). It seemed that number of the cotton aphid, Aphis gossypii GLOVER was much more on diseased plants than on healthy ones (Fig. 2). Three varieties of potato, namely Unzen, Tachibana and Chijiwa showed the same result.
    The cotton aphid, non-vector of leaf roll virus was controlled entirely by six kinds of insecticides, namely DDT, Lindane, Malathion, PAP, Diazinon and Metasystox-s (Fig. 4). The green peach aphid, vector of this virus, was entirely controlled by only Metasystox-s, but not by the others, particularly, on diseased plants (Fig. 3),
    In figures, dotted lines with open circles show the number of insect per healthy plant and solid lines with solid circles show the number of insects per diseased plant.
