1. 經過習性 1) 水原地方에 있어서 뽕나무 순집이혹파리(Diplosis mori Yokoyama)는 5世代를 마친다. 第 1世代는 6月下旬頃 第2世代는 9月下旬頃에 出現한다. 2) 成忠은 午後 7~8時頃에 出現하며 그壽命은 2~5日이며 ♀(雌)가 ♂(雄)보다 若干 긴듯하다. 3) 幼蟲은 第2~第3托葉 AB 內面과 第2~第3未開葉 裏面에 寄生한다. 따라서 生長點 附近에 被害를 준다. 4) 變態別 期間은 氣象條件에 따라서 差가 甚하며 特히 용은 旱魃時는 羽化하지 못한다. 5) 幼蟲孵化時는 乳白色이지만 橙紅色으로 變하여 老熟하며 老熟幼蟲은 15~20cm의 跳躍能力을 가지고 土中 15~30cm에 潛入化용한다. 그 크기는 0.3mm로부터 2.0mm 內外까지 發育한다. 6) 踊期間은 夏季는 7~8일 內外이며 粗雜한 繭에 쌓여있다. 7) 越冬狀態는 原則的으로 踊態越多을 하나 때에 따라서 幼蟲越多도 있다. 2. 防除法 1) B.H.C. 粉劑 土壤撒布는 老熟幼?이 入土 4~5일 後나 羽化하기前에 反黨 2%液 400~600l(20~30斗) 以上을 施用함이 效果的이라고 生覺된다. 3) 埋沒試驗에 있어서는 深度 5cm 以上이면 成蟲羽化를 防止할 수 있다고 認定된다. The insect Diplosis mori Yokoyama is causing extensive destruction of mulberry trees in Korea with a resultant loss in silk production. This study was made to determine an effective method of control. Methods and Materials Used Preliminary studies were made to determine more exactly the life cycle of the insect. Based on this information, various control measures were tested, including the use of spray methods with BHC and control of larvae by tilling. Results Obtained 1. Life cycle studies (a) In the Suwon area, this-insect has 5 generations per year. The first starts in the later part of June and the final cycle ends in the later part of September. (b) The adult insects appear about 7:00-8:00 P.M. and live for 2-5 days. Females live in longer periods than the male. (c) Larvae lives inside the second and third stipules (A. B.) before mulberry leaf development. They cause extensive damage to the leaves at the point where they are attached to the stem. (d) Weather conditions considerably affect the life cycle. The pupa particularly are affected and not be able to change into the moth stage when there is a long period of no rain. (e) Larvae are large......0.3 to 2.0mm......and are milky-white immediately after hatching but turn to pinkish as the worm matures. The matured worm has a jumping ability up to 15-20cm. The worm burrows into the ground 1.5 to 3.0 cm before changing into the pupal stage. (f) The pupal stage usually lasts 7-8 days, in summer weather conditions and the pupa is surrounded with a coarse cocoon. (g) These insects, as a general rule, overwinter as pupae but sometimes as larvae. 2. Control measures (a) BHC dust applied on the ground seem most effective. It should be done 4-5 days after the worm has burrowed into the ground. For this control, it is recommended that 6kg of a 2% formation Tanbo (10ares) be used. (b) For the effective spraying against the fly, it is recommended that a formulation of liquid BHC spray terials be used at the rate of 400-600 liters per Tanbo. (c) Tillage methods which provide a cover of soil 5cm or more in depth above infested areas will effect-maively prevent the emergence of the fly from the pupal stage. 3. Conclusions Methods of control against Diplosis mori Yokoyama can be tied more closely to the life cycle of the insect with more effective results. Further studies are needed to complete information on possible controls during or after hibernation. Economic studies on the cost of these control measures are also needed.

뽕나무 이의 생활사(生活史) 및 방제법시험(防除法試驗)
전대략 ( D. R. Chon ) 한국잠사학회 1964 한국잠사곤충학회지 Vol.4 No.-
뽕나무 이에 대한 생활사와 방제법을 조사하였다. 1) 1년에 1회 발생하며 용기가 명확하지 않다. 2) 수종의 농약으로 방제법을 구명하여 보았으나 난기에 있어서는 실용적 가치가 없다고 생각되며 유충기에 있어서는 DDVP 1000배를 10당 400l 정도이면 사멸시킬 수 있다고 믿다. 3) 방제법으로는 역시 약제와 병용하여서 정지를 잘하여서 일광 풍통이 잘 되도록 하여야 한다. Author investigated the control measure and the life cycle of the mulberry sucker, Anemoneura mori Schwarz. The results are as follows; 1. It is clear that the life cycle of mulberry sucker is one generation a year, but not obvious about the duration of pupa. 2. Even though various insecticides were used for control, they are not of a practical value during the egg stage. It is, however, believed that the mulberry sucker, when become larvae, can be controlled by spraying about 400 litres per 1 tanbo( DDVP, 1000x). 3. Author recommends the control measures which you may use not only an insecticide, but also cut off branches so as to make leaf get enough sunlight and ventilation.

방향식물(芳香植物)이 누에 생리(生理)에 미치는 영향(影響)

春夏秋 三期飼育에 있어서 硏究調査한 結果 本試驗에서 다음과 같은 結果를 얻었다. 1. Menthol의 上記添食試驗에서 Menthol의 1%內에서는 蠶兒의 生理에 何等의 影響이 없다는 結果를 얻었다. 이 結果는 누에의 上記한 實用形質 全面에 걸쳐 無害이며 또 有益하다는 點도 發見치 못하였다. 2. 薄荷를 桑田에 間作하여 支障이 없음이 硏明되었으며 薄荷葉에 摩擦된 桑葉을 蠶兒에 結與하여도 누에 生理에 何等影響이 없다. 3. 들깨(荏)에 있어서도 2項과 同一하다. 4. 結論的으로 薄荷의 桑田間作은 無害로운 作物로 思料되며 들깨의 桑田間作도 農民들이 忌避하는 傾向이 있으나 蠶兒에는 何等影響이 없다. The results for the investigation of the various aromatic plants applied diets on silkworm raising from spring to autumn crops are found as followings. 1. There was no difference between the chemical menthol solution (1.0%) enriched diet and the normal diet for silkworm physiology. Neither injury nor advantage was obtained from the investigation. 2. It was found that there was no danger to use the mulberry leaves as silkworm diet by planting Mentha arvensis L. in the vacansy of mulberry farm, and no worse effect was found by rubbing the leaves of Mentha arvensis L. to the surface of mulberry leaves before feeding to silkworm. 3. For the investigation due to Perilla Ocymoides var application in stead of menthol plant ascribed in Paragraph (2) was obtained the same result. 4. As a conclusion of the study, the plantation of the both aromatical plants with mulberry trees is harmless for silkworm growing even though farmers worry about these to plant together with mulberry tree on mulberry farm.
