초록

1000배로 희석한 "인세가"9주성분 : fenoxycarb)를 분무한 뽕잎을 일정기간 누에에 섭식시킨후 각 령의 경과일수, 5령 유충무게, 화용비율, 전견중 및 견층중 등에 미치는 영향을 조사하여 다음과 같은 결과를 얻었다. 1. fenoxycarb 첨식은 유충경과 일수를 연장시킨다. 특히 4령 3일 이후의 처리에서는 5령 경과일수가 20일 이상 길어지고 토사하지 못한채 모두 폐사하였다. 2. fenoxycarb 첨식은 5령 유충무게를 증가시킨다. 처리구의 유충무게 최대치는 대조구에 비해 2령 전기간 처리구에서 약 20%, 3령, 4령, 5령기의 전기간 처리구에서 각각 40%, 70%, 20% 정도 증가하였다. 3. 화용비율은 1령 처리구에서는 90% 이상으로 대조와 큰 차이는 없었으나 2~3령 처리구에서는 70~8-0%, 4령 후반기 이후 처리구에서는 0%였다. 4. 전견중 및 견층중은 1~3령 처리구에서 대체로 증가하였고 특히 전견중은 2령 전령 처리구에서 대조대비 47% 견층중은 3령 전기간 처리구에서 41% 증가하였다.41% 증가하였다.

The effects of oral application of fenoxycarb, the commercial formulation Insegar, to the selected developmental stages of the silkworm, Bombyx mori, was investigated. An oral application of the chemical to the silkworm from the 2nd- to the 5th-instar larvae delayed the larval development upto more than 40 days and increased the larval body weight in the range of 1.1 to 1.7 folds. When the chemical was orally applied to the final instar larvae, spinning and pupation were prevented, and consequently permanent larvae occurred. The weight of a cocoon and its shell of silkworm(bombyx, mori, L) increased following the application of fenoxycarb to the 2nd- and the 3rd-instar larvae.
