박과류에서 목화바둑명나방(Palpita indica)의 산란 및 식이선호성
최동칠,노재종,최광렬 한국응용곤충학회 2003 한국응용곤충학회지 Vol.42 No.2
수박 부위별 산란습성은 상위엽과 하위엽보다는 중간부위의 잎에 산란량이 많았고 잎자루와 줄기보다는 잎에, 잎의 앞면보다는 뒷면에 주로 산란하였다. 목화바둑명나방 유충의 작물 선호도는 오이, 박, 수박 등의 순이었고, 참외, 동아, 멜론, 안동오이 등은 중간정도이었고 수세미와 목화는 매우 낮은 선호도를 보였다. 수박시험장에서 수집한 유전자원과 육성중인 계통에 대한 목화바둑명나방 유충의 선호도는 품종 및 계통간의 뚜렷한 차이가 없었으며 보유중인 품종 중에서는 목화바둑명나방에 대한 저항성 계통을 발견할 수가 없었다. 목화바둑명나방의 섭식량을 추정하기 위한 일별 배설량은 유충 초기에 배설량이 매우 적었고 점차 증가하여 16~18일차에 최고에 달하며 그후 다시 급격히 감소하였다. The adult of the Cotton caterpillar, Palpita indica (Saunder) laid eggs more on mature leaves than on aged and developing leaves. They laid more on leaves than on petiole and stem, and more on the adaxial than on the abaxial surface side of the leaves. Larvae of the Cotton caterpillar showed their preference in the order of the cucumber (Cucumis sativus), gourd (Lagernaria siceraria), watermelon (Citrullus lanatus) > oriental melon (Cucumis melon L. var makuwa), wax gourd (Benincasa hispida), melon (Cucumis melo), star cucumber (Sicyos angulatus) > sponge cucumber (Lufa cylindrica), cotton (Gossypium indicum). There were no distinct differences among varieties and lines that were collected and hybridized at the Gochang Watermelon Experiment Station in Korea. There was a positive relationship between the leaf area and the degree of damage by the Cotton caterpillar. The feeding amounts of the Cotton caterpillar excrement were gradually increased to 16-18 days after hatching, after that the amounts of excrement were rapidly decreased.

The population density of the Cotton caterpillar, Palpita indica (Saunder) larvae was gradually increased until 10th October and then decreased rapidly after that time at the watermelon culture of rain sheltered house. After 15th October, many larvae went to soil and molted to pupae for the hibernation. Most of pupae were found in pF 2.4 soil moisture condition, but none in pF 1.5 hydro-morphic soil. Most of the pupae were found below 5cm and there was no pupa below 10cm from the soil surface. The sex ratio of the overwintering pupae was 1.09 : 1.00. For the monitoring of the cotton caterpillar adults using sex pheromone compounds, different mixture ratios of each pheromone compound were investigated with (E)-11-hexadecenal and (E, E)-10,12-hexadecadienal. Seven versus three ratio of (I)-11-hexadecenal and (E, E) -10,12-hexadecadienal was more attractive than any other ratio, and then followed by 6 : 4, 8 : 2, 9 : 1, and 5 : 5 mixtures. As a result of monitoring with 7 : 3 mixture of (E)-11-hexadecenal and (E, E)-10,12-hexadecadienal, occurrence peaks of cotton caterpillar adults showed 4 times per year. The first time of adult appearance was late July in 2000 and middle July in 2001 and the highest number was collected on late September. 수박재배 하우스에서 목화바둑명나방은 유충이 10월 10일까지 높은 밀도로 유지하다가 10월 15일부터 급격히 밀도가 낮아지기 시작하고 번데기는 10월 15일 이전에는 수박잎이나 과실이 땅과 접촉하는 부위에 있으나 그 이후부터는 지하부로 이동하여 토양속에서 월동하였다. 월동 번데기는 토양의 습도가 pF 2.4정도인 토양에서 대부분이 발견되었으며, 건조한 토양이나 과습한 토양에서는 거의 발견되지 않았다. 하우스 내 월동번데기의 분포는 수박덩굴의 상위엽이 위치해 있었던 부분의 토양내에서 가장 많은 번데기가 발견되었다. 또한 토양 내 수직분포는 지중 5cm 이하에서 대부분이 발견되었으며, 지하 10cm이상에서는 전혀 발견되지 않았다 전체 월동번데기의 암수 성비는 1.09 : 1.00으로 성간에 큰 차이가 없었다. 목화바둑명나방 발생예찰을 위한 성페로몬은 (E)-11-hexadecenal과 (E, E)-10, 12-hexadecadienal을 7 : 3으로 혼합했을 때 가장 유인량이 많았다. 가장 유인효과가 좋았던 (E)-11-hexadecenal : (E, E)-10, 12-hexadecadienal 7 : 3의 페로몬을 이용한 시기별 발생소장 조사에서는 4회의 발생성기를 보였는데 7월 중하순에 처음으로 유인되었고 9월 하순에 가장 유인량이 많았다.

This study was surveyed and analyzed in 2005 year for environmentally-friendly rice’s production 78 farmers in korea. The major results was as follows : The average age of farmers were 54 years old, the experiences of environmentallyfriendly rice’s production farms was 7.4 years, the cultivated scales of environmentally-friendly rice’s production was 3.4ha. The 74%’s Farmers of all unified rice"s breeds for rice’s production of high-grade in quality, the ranking of rice’s breeds selection were the high-grade rice’s breeds of government>japan rice’s breeds. The control of damage by blight and insects were needed environmentally-friendly control, the endured study of this control were very important. To cut down cost of the environmentally-friendly rice for income security of farmers and sustenance of farming will. To receive reasonable price of environmentally-friendly rice, the brand image were raised to consumers, the variety and miniaturization of rice packaging unit were needed in view of consumers. In addition to must be campaigns of publicity through the press and event to consumers, were managed the exchange of rice goods and exchanged e-mail together consumers for the maintenance of confidence. To drive direct marketing between environmentally-friendly rice farmers and consumers through experiential marketing, to diversify the marketing channel. To strengthen public relations at regional level and relationship at the consumers.
