Phosvel분제, Malix분제, Salithion유제, DDVP유제, Cidial 유제의 성충에 대한 방제효과가 우수하였고 핵충에 대해서는 Satchukoto-S유제, Salithion유제가 비교적 우수한 편이였다. The mulberry small weevil, Baris deplanata ROELOFS, has highly infested mulberry trees in Korea. As the damage caused by the mulberry small weevil in mulberry fields has been increased over the country since 1969, the authors has carried out a series of biological and controlling studies on the pest from 1971 to 1972. The results obtained are summarized as follows. 1. The adult weevil is elongate oval in shape with black in color and the probocis is long as usual in curculionidae. The size of adult female is 3.30±0.04mm in length, 1.47±0.04mm in width, and the length of proboscis is 1.25±0.014mm, while adult male is 3.28±0.06mm in length, 1.40±0.04mm in width, and the length of proboscis is 1.30±0.02mm. The antenna is geniculate consisting of 12 segments. The terminal sternite of the abdomen has a pointed tip in male but not in female. 2. The egg is long oval in shape, milky white in color, 0.51±0.05mm in length and 0.32±0.02mm in width. 3. The mature larva is cylindrical and light yellowow in color except the head of dark brown, and legless, 3.88±0.06mm in length, 1.40±0.02mm width, each segment bearing many wrinkless and short setae. 4. The pupa is long oval, milky white and exarate, 3.53±0.09 in length, 1.40±0.03mm in width. 5. Majority of the species has one generation through a year and overwinters as adult in xylem of withered branch and come out again from late April to early May in next year. But some of the female oviposit in the same year and the offsprings overwinter as larva (0.4%) or pupa (0.1%) 6. The eggs are mostly laid under the cork layer of withered branch and the number of eggs deposited by an adult female is 73.44±8.74, the average egg-laying period is 33.88±6.04 days. The incubation period is 11.69±0.39 days, the larval period 45.04±1.63 and the pupal period 11.05±0.49 days. The period of adult`s activity is 46.7±5.90 days. 7. The larvae feed on the cambium under the bark and adults feed on the winter bud, the latent bud, the leaf stalk and the base of newly shoot. 8. An active period of adults was observed during the period of 4 months from April to July. However, the peak of adult-density occurred in the early May (in the fields of spring-prunning) and early to middle June(in the fields of summer-prunning). 9. There is a positive correlation between the density of larvae and diameter and length of the branches. 10. The pattern of distributions of the adult of mulberry small weevil is negative binomial distribution. 11. The chalcid fly was disclosed to be a natural enemy which was parasite on the larvae of mulberry small weevil and its parasitic ratio was 11.9%. 12. Phosvel D, Malix D, Salithion EC, DDVP EC, and Phosvel EC were effective for the control of adults and Satchukoto-S EC, and Salithio EC were effective for the control of larvae.

하추기 뽕나무 총채벌레의 우수 방제 약제 선발과 총채벌레 피해뽕잎이 잠작에 미치는 영향 및 뽕잎 성분 변화를 구명키 위한 시험에서 얻어진 결과를 요약하면 다음과 같다. 1. 총채벌레 방제에 우수한 효과를 나타냄. 약제는 Ortran, Furadan, Metasystox 이었으며, Ortran과 Furadan의 약효 지속기간은 25일로 제일 길었다. 2. 총채벌레 피해뽕잎과 방제 뽕으로 누에를 사육한 결과 수견양이 방제뽕잎구는 상자당 3.68kg (10a당 5.15kg)이 증수되었다. 3. 방제뽕잎중의 수분 및 전탄수화물의 함량은 피해뽕잎중의 그것보다 높았고, 피해뽕잎이 조기에 경화되는 경향을 보였다. This study was conducted out to evaluate the efficacy of insecticides, furadan (3%G), disyston (5%G), ortran (50%WP), pirimor (50%EC) and metasystox (25%EC) to the mulberry thrips (Pseudodendrothrips mori NIWA.) The comparisons between damaged by thrips and controlled leaves with the cocoon producion and the chemical contents in leaves were carried. The results were as follows; 1. Ortran, furadan and matasystox showed the good efficacy to control the thrips, especially the period of efficacy was the longest in ortran and furadan. 2. The cocoon yield increased in the controlled plot by 3.68kg/box and 5.15kg/10a more than in the damaged plot in autumn rearing season. 3. The content of total carbohydrate and water in mulberry leaves was clearly higher in the controlled plot than in the damaged plot. This may cause the earlier leave harding by damage in autumn.

1. 발생소장은 기상환경 중 강우량 및 일조시수에 큰 영향을 받으며 8월초 밀도가 급증하여 하순에 Peak를 나타내었다. 2. 엽위별분포는 상부로부터 4-16엽이 분포하고 그 중 6-12위엽에 최대로 분포하였다. 3. Orthene, Metasystox의 방제효과가 우수하였다. Experiments had been carried out in Suweon area from 1972 to 1973 to determine the seasonal fluctuation of Pseudodendrothrips mori NIWA using direct counts and to know the effects of chemicals for its control. 1. The fluctuation of mulberry thrips was especially influenced by precipitation and number of hours with sunshine in the meteological conditions. The peaks of fluctuation occurred several times but the highest peak occurred in late August. 2. The mulberry thrips was distributed in the range of the 4th to 16th leaves from the apex in a branch. The highest density leaves were 6th to 12th. 3. Orthene, Metasystox were the most effects on the mulberry thrips.

白鉉俊,韓相贊,金永澤 한국잠사학회 1987 한국잠사곤충학회지 Vol.29 No.1

The fauna and the distribution of plant parasitic namatodes were investigated by sampling about five hundred grams of soil around roots of mulberry trees from 929 mulberry fields in Korea. Of fourteen genera detected on mulberry fields, Paralylenchus aciculus, P. projectus, P. morius, Iielicotylenchus dihystera, Meloidogyne arenaria were found to be parasitic to mulberry. Among them Paratylenchus species were the most abundant in mulberry fields, but Tylenchorhynchus sp., Aphelenchus sp., Helicotylenchus sp., and Meloidogyne sp. were also observed in high frequency. Meloidogyne species were observed in high frequency in Jeonbuk, Gyeonggi and Jeonnam, IIelicotylenchus sp., in Gyeongnam and Gyeonggi, Xiphinema sp., in Jeonbuk and Jeonnam, and Paratylenchus sp., in Gyeonggi, Gyeongbuk, Gyeongnam, and Jeonnam. The growth of mulberry was poor as the increase of density of Paratylenchus sp.

The effects of nematicides on root-knot nematode were investigated in the mulberry nursery farm of Jeonnam province from 1985 to 1986. The nematicides applied were Fenamiphos, D-D(92%) , Aldicarb, D-D (55%), Ethoprop and Carbofuran. The control effects of nematicides used were similar in two years (1985 and 1986). The Fenamiphos and D-D (92%) both were a highly effective than any of Aldicarb, D-D (55%) and Ethoprop, Carbofuran. Mulberry sampling showed good growth when the above nematicides were applied.

金永澤,白鉉俊,李載昌 한국잠사학회 1987 한국잠사곤충학회지 Vol.29 No.1

The incidence of mulberry dwarf disease was surveyed on seventy two cocoon producing areas throughout the country from 1983 to 1984. There was a low tendency of incidence in Gyeonggi, Gangwon and Chungbuk, the northern parts of 37 degrees north latitude. However, in Chungnam and Gyeongnam, was a relatively high incidence observed. The most severe incidence areas of mulberry dwarf disease were found in Jeonnam, Jeonbuk and Gyeongbuk.
